The Sony Bravia V3000 series was the most popular request in our latest VIP Poll. I have tested and published my findings on the Sony KDL40V3000.
On an interesting note, I see my competitor over at hdtvorg.co.uk has published a review of the Panasonic TH42PX80. Nothing wrong there, except that on closer inspection it is a word-for-word rehash of their own TH42PX70 review. Have a look at the following screen captures from their website.
From hdtvorg.co.uk/reviews/plasma/panasonic_th42px80.htm:
From hdtvorg.co.uk/reviews/plasma/Panasonic_th42px70_2.htm:
Given HDTVOrg’s past history of plagiarism, constant rehashing (check out the “Performance” section of their Samsung PS63P76FD review which is again completely rehashed from the corresponding section in their PS50P96 review, but somehow they forgot to substitute the model name), and the fact that I haven’t seen anything but generic stock photos on their website, I suspect that HDTVOrg actually writes bogus reviews without having seen many (if any) of the TVs himself.
Part of what motivates me to continue reviewing HDTVs is the sense of achievement I get from publishing my reviews way before the likes of What Hifi and Home Cinema Choice (because I’m not afraid of buying the televisions myself if there’s popular demand in our VIP poll). But how can you compete against someone who can fabricate an entire review at the drop of a hat?
On this bombshell, if you’d like to see us buy and review the Panasonic TH42PX80, I have started a fundraising to help me cover my loss when selling the plasma as second hand after the review. I have been in touch with Panasonic, but they told me that they haven’t received their loan stock in yet, and even if they had they would send the pioneer batch to the major publishing houses first.
Panasonic TH42PZ85 is one of the first true HD plasma televisions from their new 2008 range of HDTVs to arrive on UK shores. The TH42PZ85 boasts Panasonic’s latest motion-compensated frame interpolation (MCFI) technologies – “Intelligent Frame Creation” and “24p Real Cinema” – that separates it from the PZ80 series (available at a slightly later date) which is also blessed with a native screen resolution of 1920×1080.
Our Panasonic TH42PZ85B review will pay particular attention to the effects of Intelligent Frame Creation (IFC) to determine if it’s worth paying extra for this technology over the PZ80 series.
In case you’re wondering about the difference between Panasonic TH42PZ85 and TH42PZ85B when shopping around, there is none: the alphabet B at the end of the model name simply denotes the British version which comes with a 3-pin power plug. Europeans, on the other hand, get the Panasonic TH42PZ85E. Picture performance should be similar across the board.
The Toshiba 37XV505DB is the first of their Regza XV range of LCD televisions we managed to get our hands on to review. Replacing the ever-so-popular Regza X series, the new Toshiba XV LCD TVs feature true high definition (HD) 1920 x 1080 native screen resolution, “Luma Sens” technology which automatically adjusts the LCD backlight depending on the ambient light detected to improve blacks and save energy, a full power down mode which consumes even less power (compared to standby), and a dedicated game mode that decreases input lag for better gaming experience.
While researching this LCD HDTV on the internet, you may have come across different model names such as Toshiba 37XV503DB and Toshiba 37XV505DB. They are essentially the same panel (in terms of specifications and presumably picture performance) bar some minor cosmetic differences. However, some retailers have taken advantage of this difference in model name to refuse price-matching requests which may erode their profits.
Remember the Hitachi 1.5 UltraThin LCD HDTVs you saw at CES earlier this year? Well the 1.5 Ultra thin series has now been released in the US in two separate model ranges. First up is the Hitachi Directors series X, and the Hitachi Ultra Vision V series. We will be talking about the X series / directors series here.
The 1.5 ultra thin sets had a huge amount of attention at CES and rightly so, they are just 1.5-inches thick or thin. The Director’s Series Models will be avaliable in four sizes, from 32-inches to 47-inches. On the larger end, we have the 47-inch Hitachi UT47X902, 42-inch UT42X902, and 37-inch UT37X902, all with a 1920×1080 pixel full 1080p HD resolution, 120Hz Reel120 technology and two year warranty.
On the smaller end of the Hitachi X series, we have the 32-inch UT32X812, and UT32X802. The former features the 120Hz Reel120 technology, while the latter does not. Both have a 1366×768 resolution and 2 year warranty. The unrivaled thinness also comes with a great 360 degrees design that is appealing all around. All come with an optional audio video center.
One of the most exciting HDTVs announced this year by the major brands is the Samsung Series 6 650 range. The Samsung 6 / 650 series consists of six different sized models, and sitting right at the very top of the series is the largest 52-inch Samsung LN52A650.
The Samsung LN52A650 seems to be a straight winner, with an amazing new look featuring Samsung’s “Touch of color” and the very latest and highest specifications and features to being the very best in HD viewing. If your looking for a stylish and modern LCD HDTV, with a large screen size, and also great features, the LN52A650 should suit you very well.
Offering the highest HD format called Full HD / 1080p the 1920×1080 pixel LCD screen offers the native resolution for blu-ray and will show the best image quality for a screen this large. Along with 1080p, Auto Motion Plus 120Hz high frame rate keeps image sharpness and clarity during fast moving scenes, and scenes free from image judder, often seen during image panning. A high 178 degree viewing angle enables easy viewing from around the room, and the fast 4ms response time works well with the 120Hz technology for motion blur free viewing. A massively high contrast ratio of 50,000:1 ensures vivid and natural colors with deep black levels.
From use of the Ethernet port on the Samsung LN52A650, you can access the latest news, weather, stock info and sports news with a simple press of the button on the remote via the InfoLink RSS technology.
Other connections on the LN52A650 are very healthy with a nice collection of four HDMI 1.3 inputs (1 on side), 2x component, s-video, composite and PC VGA input.
Samsung have given the plasma HDTV market some love with it’s latest 50-inch plasma offering, the Samsung PN50A550. Samsung looks set to win some of the plasma market back from Pioneer with the PN50A550. It comes from the new Samsung Series 5 range, and offers a full HD 1080p resolution, with advanced processing to improve image quality and reduce noise.
The specifications look very impressive on the Samsung PN50A550, with a very high contrast of 30,000:1 for great colors and black levels, along with 18-bit processing for smooth color grading and Samsung’s Ultra FilterBright technology. Connectivity is very good also, with three HDMI 1.3 inputs, PC VGA input, component, s-video, and USB 2.0 for photos and music playback. Cnet took a look at the PN50A550 and say, excellent picture, with highly accurate colors, very little noise, and solid processing. Unlike most HDTVs we’ve tested, the Samsung PN50A550 was able to successfully de-interlace 1080i film-based material once Film Mode was engaged.
PC connection on the PN50A550 is also very good via both the HDMI and VGA inputs, resolving all details at the perfect 1920×1080 pixel resolution.
Panasonic is doing a great job this year with it’s new range of LCD HDTVs, and the very well impressive and well priced Panasonic TX-32LZD85 stands out well. The TX-32LZD85 has some more advanced features over Panasonic’s lower end models, such as the high 100Hz refresh rate which cuts down on motion blur and image judder, while increasing image sharpness and detail by adding in extra frames.
The Panasonic TX32LZD85 features a full HD 1080p LCD screen with 100Hz, 24p and a Motion Focus system brining you the very best in HD from a blu-ray movie. The 1920×1080 pixel resolution is still rare for a screen of this size, and along with the image enhancing V-Real image processing engine, the TX-32LZD85 can produce an amazing image with a very high contrast ratio of 10,000:1 for vibrant colors and deep black levels. TReviews said the TX-32LZD85 delivers greatly, making it easily the company’s best LCD HDTV yet.
Inputs are good on the Panasonic TX-32LZD85 with three HDMI 1.3 input, component, PC VGA input, a SD card slot for viewing photos, and digital audio out for a separate audio system.
At their press conference, Philips used the occasion to great effect (light show and dance intro, fashion catwalk, and even a specially-commissioned film by esteemed director Wong Kar Wai) to drum up interest in their new Aurea 42PFL9900D LCD that could be best described as “Ambilight In Bezel”. Notice in the following video how the colour/ intensity of the light zones embedded within the bezel changed according to what was displayed on screen:
If you feel that the Aurea is too distracting for your taste, there’s always the conventional Ambilight models to fall back on. I am always very impressed with Philips televisions’ performance in showrooms, and this time was no different. They put up a few of their EISA-award-winning Philips 47PFL9732D LCD TVs side-by-side in on/ off mode to demonstrate their 100Hz Clear LCD, Perfect Pixel HD and HD Natural Motion technology. While I believe that the effects were exaggerated (for example, the judder on the “HD Natural Motion Off” screen was much worse than your usual telecine judder), these nevertheless gave a glimpse of what the new generation of Philips LCDs are capable of.
Panasonic
Overall the Panasonic booth was quite dark with the only significant light source coming from all their television screens, which of course showcased the already excellent blacks on their plasmas. Current full HD models like PZ700 and PF9, and the newer TH42PZ70 (which will have twice the quoted contrast ratio but cost £500 less than the outgoing TH42PZ700) were on show, but it was the 103-inch behemoth of a plasma TH103PF9 that grabbed the crowd’s attention (it was placed in a dedicated room with surround sound). Here’s a picture… if you look closely you may see someone standing to the left of the picture which gives you a scale of how humongous that screen is:
Panasonic will also – for the first time – venture beyond 32 inches in their LCD product lineup: the 37″ Panasonic TX37LZD70 LCD TV will feature a full HD 1920 x 1080 screen based on IPS-alpha panel complete with 100Hz Motion Picture Pro technology. Given the low ambient lighting condition, I couldn’t help but notice the average blacks, but hey, I’ll be the first to hold my hands up and admit that it was not calibrated (so black level could be brought down if Panasonic are considerate enough to introduce a long-overdue backlight control). Viewing angle, as always, is one of the best in the LCD business:
Samsung’s exhibition stand covered the largest area among all the HDTV manufacturers I’d visited at IFA Berlin 2007. Strategically positioned near one of the main entrances, it was crawling with dealers, journalists and consumers… like they were holding a trade show of their own. This is probably a testament to the popularity (read: value-for-money) of their products, not to mention their financial clout as the world’s leading consumer electronics company.
Being someone who avidly follows all the advancements in the high-definition television industry, I naturally hustled and bustled my way through the crowd to home in on a pair of LED-powered LCD TVs, the 52″ Samsung LE52F96BD and the 70″ LE70F96BD. Armed with an array of local-dimming LED matrix, the backlight can – theoretically – be shut off totally to produce an absolute black level that’s even lower than the Pioneer Kuros, resulting in an extremely high contrast ratio (Samsung have quoted us a figure of 500,000:1).
While across the pond US consumers have been able to buy and enjoy these LED LCD TVs since 2 weeks ago, here in the UK I probably would still have to wait for a little while longer before getting my hands on a sample to review in the home environment. What I have received though is a Samsung LE40F86BD LCD TV, which is the next step up from the LE40M86BD with 100Hz Motion Plus technology and a higher claimed dynamic contrast ratio:
Sony has launched their new Bravia W4000 range of LCD HDTVs—comprising the Sony KDL40W4000, KDL46W4000, KDL52W4000 and even a 32″ 1080p true HD KDL32W4000—according to a press statement released on 31 March 2008. Here are some snippets of the press release along with our analysis.
XMB is short for XrossMediaBar, Sony’s award-winning graphical user interface (GUI) found on the Sony PS3 and the latest US Bravia LCD HDTV models (e.g. XBR4/ XBR5). This is the first time we will see it implemented on a full HD 1080p HDTV aimed at the UK market.

ส่วนที่เหลือ
LG has released two new series of plasma TVs in the UK market: the PG3000 and PG6000. Both come in 42″ and 50″ versions, and feature LG’s Dual XD video processing engine and 100Hz technology, though neither boasts a true HD 1920 x 1080 native screen resolution.
The LG PG6000 range probably offer better value-for-money than the PG3000: for only between £50 and £100 extra at this time of writing, you get a higher contrast ratio (30,000:1 vs 20,000:1), an extra HDMI 1.3 port (four vs three), an eye-catching “frameless” design, and better USB port functionality (the one on PG3000 can only be used for software upgrades and not JPEG photo viewing).
Of particular interest would be the LG 42PG6000, which will go head-to-head with the new Panasonic TH42PX80 in terms of specifications and price:
Background:
As the HDTV market continues to heat up, consumers are in need of being educated on the latest technology. One of the terms that you, the consumer, will surely run into while selecting a HDTV set is: HDMI. For most this is an unfamiliar term and we will explain the details of HDMI in this article so you, the consumer, is armed with the proper knowledge to make intelligent purchasing decisions.
What is HDMI: HDMI is an acronym for High Definition Multi-Media Interface. The HDMI specification (now at 1.2) was created by some of the largest consumer electronics manufacturers in the world: Hitachi, Matsushita, Philips, Silicon Image, Sony, Thomson, and Toshiba. HDMI is the latest digital HDTV interconnection standard. The notable differences between HDMI and the earlier HDTV interconnects standards (component video, and DVI) are:
-HDMI is all digital unlike analog component video cables
-HDMI supports multi-channel audio in addition to digital video. (DVI only supports digital video)
- HDMI is more compact in size and carries both audio and video signals therefore eliminate cable clutter.
-HDMI incorporates content protection called HDCP ( high definition content protection)
What does a HDMI connector look like: HDMI looks similar to a USB cable. The compact size and high integration (carries both audio and video) makes the HDTV installation experience truly "plug and play."
Why should I use HDMI:
-HDMI is all digital, so picture quality is "perfect" from source to display
-HDMI is both a digital audio and video connection. This will minimize cabling in your system
-HDMI is rapidly becoming the de facto standard for HDTV connections.
How does HDMI transport the digital video: The video portion of HDMI is carried by 3 separate differential pairs. Each pair transports 1 of 3 uncompressed native digital R,G, B signals from source ( dvd player,set top box) to the sink ( HDTV display). A unique protocol, T.M.D.S.( transmission minimized differential signaling), is used to transport the digital data. Each pixel is represented by 24 bits ( 8 bits each for each of the primary colors). The T.M.D.S. protocol then "calculates" and stuffs 2 extra bits to the video data stream in order to create a digital stream with minimum transitions ( lower EMI, lower interference) and also minimize long strings of '1' and '0' which can cause detection errors.
A fourth differential pair, called the TMDS clock provides the pixel clock for timing the data stream. The maximum TMDS single link pixel clock rate is 165 MHz.
What is the data rate of a single link HDMI connection: The maximum pixel clock rate is 165MHz and each of the 3 TMDS video streams carries 10 bits. Therefore the aggregate data rate is 3 x 10 x 165MHz = 4.96Gbps.
How many pins are included in the HDMI connector: There are 19 individual pins in the HDMI connector. There are 3 pairs of TMDS signals which carry all the digital audio and video signals.
How is the digital Audio signal transported: The multi-channel audio is time multiplexed into the TMDS data streams. Audio is much lower data rate (192kbps) and the extra time is used to demux the audio signals.
What is HDCP: HDCP is an acronym for High-Bandwidth Digital Content Protection. HDCP is an encryption method developed by Intel in order to control unauthorized copying of digital media. The encryption is carried out in the HDMI transmitter found in the "source" ( dvd player, set top box) and decryption is carried out by the HDMI receiver ( the HDTV display). The secret keys for encryption are exchanged between the source and display over an I2C bus ( pins 15 and 16).
Is HDMI compatible with DVI: DVI is the predecessor to HDMI. HDMI and DVI are identical as far as video is concerned. Therefore, video backward compatibility exists. However, DVI will not support digital audio. For example, if you have an older DVI connection on your source and a HDMI connector on your display, a HDMI to DVI cable is all that is needed in order to view the video. A separate audio cable ( TOSLINK or SPDIF) will be needed to carry the digital audio.
What formats will HDMI support: HDMI is high speed digital connection and will support resolutions of 480i, 480P, 720i, 720 P, 1080i and in the future,1080P.
Conclusion:
HDTV technology is changing rapidly. HD connections such as HDMI will become the de facto standard in HDTV connections. We have outlined the important features of HDMI, so the consumer is well informed and ready to make intelligent purchasing decisions.
Analog
An analog television receives signals via satellite, over the air or through a cable; whereas older (standard) televisions accepted signals from radio waves transformed into sounds and screen images.
Digital
Digital television (DTV) converts signals for DVD players to analog. However, limited pixels limit resolution for viewers, affecting quality imaging on the television screen.
Reportedly U.S. broadcasts are moving in the direction of DTV transmission, transmitting video and sound data zeros and ones over wave transmissions, basically using the UHF spectrum over the air with a 6 MHz bandwidth, similar to analog transmitting.
Features and benefits of DTV include:
• Better quality image.
• Better resolution with big screen TVs
• Better video graphic imaging.
• Multicasting.
• Interactive content can be transmitted.
• High-definition (HDTV) compatibility.
Bad news: older standard analog televisions cannot show DTV productions. So you may still need two TVs at this time, depending upon cable and how late you stay up and want good content, etc.
HD
HDTV is part of DTV. It carries the highest standards for DTV, as set forth by the Advanced Television Standards Committee (ATSC) for digital television.
Of the18 digital broadcast formats for video, the top tier for HDTV needs to reflect the following over analog and other lower standards with respect to:
Aspect ratio - HDTV must have a 16:9 aspect ratio; standard TV only needs a 4:3.
Resolution - HDTV needs high resolution, like up to 1920 x 1080 pixels; standard TV only needs 704 x 480 pixels.
Frame rate – HDTV needs the highest frame rate (like screen speed), at least 60 frames per second. Standard TV is under 24.
The mains things to note with high-definition visual and sound are twofold. Number one, the television station needs to be transmitting high-definition signals. Without that much, no need to continue. And number two, you need to have the right television equipment to receive and view the high-definition transmissions.
So get informed and check out your systems and equipment! It’ll make upgrading to HDTV that much easier – and enjoyable for your family.
What was then a crude box of wires and valves and brushes, is a magical tool that provides crystal clear pictures and surround, natural sound from a size of not more than your two skateboards put together! Today`s television quality has been defined by the introduction of High-Definition TV (HDTV).
It is a digital broadcasting system that allows more video compression, less bandwidth and most importantly clears and superior quality pictures or video. HDTV provides an image resolution of around 720 lines of progressive scanning range (720p) to 1080 lines of interlaced scanning (1080i). The quality and superiority of HDTV is unmatched as per now. The image resolution is much higher as compared to conventional TV sets. But television`s superiority hasn`t stopped at HDTV itself. A new introduction has been made to the superior range of televisions today.
Full HDTV, or ultra-HD, true HDTV or 1080p has excelled over the quality of HDTV sets. The image resolution, picture quality and sharpness are all much higher than HDTV sets. Full HDTV sets provide an image resolution of around 1920 by 1080 pixels.
Full HDTV uses the progressive scanning technique to produce an image, while other HDTV sets use the interlaced scanning technique. The former is superior as the jitter factor is ruled out considerably than in the latter. The former is better for video displays or moving objects that move diagonally or vertically from one part of the screen to another. The progressive scanning used in it is also important as per the following factor. The fact that a clean, sharp and distinct superior quality video is only possible in LCD sets, Plasma sets and also with micro displays is only provided by progressive scanning is a boost for Full HDTV sets.
The picture quality in full HDTV sets is far higher than conventional and other HDTV sets. This is because in large screen TV sets, the pixels are less in number and hence are magnified to occupy maximum screen space. This gives a deteriorated picture quality. But due to the high quantity of pixels in the Full HDTV sets, picture quality automatically gets smoother and better. Vastly detailed pictures and video can be viewed and provides an optimum quality of TV viewing experience.
Nowadays, in the age of the Home Theater, DVDs and VCDs, films are often watched sitting in the comfort of home. Full HDTV sets provide you with the best option available, as huge screens (conventional or flat) only provide you with optimized video content only with the full HDTV system. Not only is the film-experience aggravated, but also lends it an authentic touch as of excellent picture quality as in cinema halls and theaters.
Full HDTV has been so successful only because of the high-definition digital broadcast of programs. But the same can be said the other way round. Probably, in the coming generation, television will attain even more advanced forms. But it is correct to state that only with the initiation of the full HDTV sets, was the sweeping modernization of sleek television truly born. As the new age television takes its place in drawing-rooms all across the world, full HDTV acts as much more than a mere complement to it.
* The HDTV TV set itself
* A media supplier, cable ,satellite or local stations
* A signal provider, antenna, cable, satellite
Firstly it would be advisable to look for your HDTV set. You should find two kinds of sets available. The most common at the moment is the HDTV ready set which means it has the capability to upgrade at a later time to receive high quality broadcasts but does not do so at the moment. It will adequately give reasonable standard picture quality but not high definition.
Secondly there is the integrated set. This TV set has the correct components i.e. a in built digital tuner, so you can install a HDTV antenna and receive a wide screen high definition signals.
HDTV Info About Signals
After searching around for HDTV info about the TV signals the conclusion will be that there are various types of ATSC signals. There are no current HDTV sets that will convert and display all of them on the one set. What happens is the HDTV set receives a couple of these signals and displays a scaled down view which is adequate for general watching under most conditions.
Your HDTV info will let you know that there are further continuing improvements being implemented to improve the digital signals across the board which means that the local resolutions available will dove tail the signals you need for optimum high definition display. Having a set that is capable of producing high frames rates will be of no advantage to the owner as this does not produce better picture quality when receiving lower frame rate signals from your local signal provider. As mentioned, this will improve over time.
So which signal provision will you choose. Be it satellite, cable or antenna. HDTV info is readily available from each of these providers and some stores are well stocked with HDTV info just to confuse you even more. But as long as you decide on a particular signal supplier first and then match your HDTV set to it you should be on track. It is no use to find the best HDTV with all the state of art gadgets if the signal provision in your area will not be sufficient to give this wonderful technology the best show it can deliver. Some signal providers have matched their technology to the manufacturers capability and provide packages which makes the HDTV info gathering a lot easier. Just choose your signal provider and match the HDTV to it.
The proper antenna choice is dictated by numerous factors, most of them are derived from your location. The most important step in HDTV antenna selection process is to find out what broadcasts are available in your area, which frequencies (channels) they are transmitted on, and which CEA color area you are located in with respect to the transmitting towers. Consult HDTV Antenna Labs guide and follow the selection process.
In most cases an outdoor antenna is the way to go. Indoor antenna reception quality is always inferior to the quality obtained with an outdoor antenna, especially in remote areas. However, of you live in a HD signal saturated area in the immediate proximity to the towers, then an indoor HDTV antenna may work great for you.
There are many reasons for using indoors antennas, most of which have to do with the inability of installing an outdoor television antenna. Indoor HDTV antennas are especially popular with individuals living in apartments. Your home may simply not have the space to mount an outdoor antenna, and there are several indoor models that serve as space savers while providing you with reception.
Many individuals choose to purchase an indoor TV antenna instead of its outdoor counterpart for aesthetic reasons. Some housing developments and neighborhoods have gone so far as to ban outdoor TV antennas, especially neighborhoods of historical homes. For this reason, and indoor HDTV antenna still allows you all the fantastic qualities of HDTV while not marring the physical look of your home with an unsightly antenna.
Normally, indoor antennas do not require any maintenance and the troubleshooting is trivial. This is not always the case with outdoor antennas. Strong winds, and stormy weather in general, may cause damages to rooftop antennas. Professional assistance in the roof antenna installation is recommended.
The major issue with indoor TV antennas is a poor reception of weak HD signals. Performance of any particular indoor antenna type or model is hardly predictable because it depends on so many factors - construction materials of the building, the exact placement in the house, other objects located near the antenna. For these reasons, Consumer Electronics Associations (CEA) does not rate indoor antennas by CEA color areas as they do for outdoor antennas. With indoor antennas nothing is guaranteed.
Although an outdoor antenna can potentially pull in more TV channels, its higher cost, bigger size and installation hassle can turn your decision in favor of an indoor antenna. Audiovox, RCA, Samsung these are just a few of many indoor HDTV antenna manufacturers. All of them offer similar products. For VHF TV channels 2 to 13 all you have is the well known rabbit ears antenna. Anything more sophisticated than that in VHF band would be simply too large to place indoors. UHF antennas are smaller and a consumer has many antenna types to choose from. The most basic (and poorly performing) is the UHF loop antenna. More sophisticated UHF antenna types are directional log-periodic and scatter plane antennas.
When considering the particular antenna types and brands, be sure to research a specific model before you buy. Look at customer reviews and compare antenna specifications carefully.
HD (high definition) refers to the quality of the picture being transmitted to your television set.
Picture quality is measured in scan lines. The more scan lines that are transmitted to your TV, the clearer the picture.
For instance, analog (over-the-air) TV has 525 scan lines per image. HDTV, on the other hand, has up to 1,080 lines per image -- almost twice as many lines of resolution giving you twice the clarity of analog TV.
There's a huge difference between watching TV on a regular TV set as opposed to watching an HD TV. The HD picture is sharper and the colors are brighter. The picture is so realistic it's almost like watching a scene through a window.
HD Satellite TV Features
Here are the main features of HD satellite TV:
* High resolution picture -- HDTV produces a super-sharp image, resulting
in a clearer, more lifelike picture.
* Widescreen picture -- you get a full-width picture just like you see in the movies.
* Digital audio -- HD audio programming is broadcast Dolby Digital format so you get a three-dimensional surround-sound listening experience.

The Bottom Line
The only drawback to having HD satellite TV is the cost. If you don't already own an HD TV set, then you'll have to buy one. And the HD programming fees are another expense that will add to your satellite TV bill.
However, if you want to see your favorite shows in near lifelike clarity and you can afford the extra expense, having HD satellite TV is definitely worth the added cost.
People were amazed by the technology of being able to watch live broadcasts from across the world, films and sports all whilst not having to leave their homes.
Then came along colour!
Obviously, we have come a long way since then, what with the capabilities of computers and the internet, video calling and other technological advances, having colour television all seems a bit primitive.
Since colour television there also have been some more advances for our viewing pleasure.
There was the VCR, giving people the choice of recording their programmes or buying video’s for their kids.
Then came along DVD. DVD produced improved quality in audio and visual a normal VCR cassette couldn’t compete with, as well as separating the films into scenes and sections, and adding extras.
Now with digital television widely becoming the standard, we have LCD (Liquid Crystal Display) & Plasma screens, again improving picture quality whilst saving space. But it doesn’t stop there.
The new technology that again, will improve the viewing pleasure is ‘High Definition TV’ or HDTV for short.
So, what is HDTV?
HDTV is the latest generation of digital TV, providing life-like picture quality, at least four times superior to current standards. It will provide extremely clear and fine picture detail with richer colours, improving the visual experience.
At launch, HDTV is thought to be available from BSkyB. In order to view programmes broadcast in 'High Definition', a soon to be released HDTV Sky Receiver with Sky+ technology will be required. In addition, the benefit of High Definition will only be apparent through a HDTV television (ideally plasma or LCD).
Please note, not all Plasma & LCD televisions currently available are HDTV compatible. It is expected to become available in the first quarter of 2006.
The terms HD ready and HD compatible are being used around the industrial world for marketing purposes. They indicate that a TV or display is able to accept video over an HDMI connection, using a new connector design, the main purpose of which seems to be to ensure that digital video is only passed over an interface which, by agreement, incorporates copyright protection. Even HD-ready sets do not necessarily have enough pixels to display video to the 1080-line (1920x1080) or 720-line (1280x720) HD standards in full resolution without interpolation, and HD-compatible sets are often just standard-definition sets with an HDMI input. This is a confusing use of the terms HD and hdtv.
MPEG-2 is most commonly used as the compression codec for digital hdtv broadcasts. The hdtv is capable of "theater quality" audio because it uses the Dolby Digital (AC-3) format to support "5.1" surround sound.
Japan has the earliest working hdtv system still in use, with design efforts going back to 1979. Japan began broadcasting analog hdtv signals in the early 1990s using an interlaced resolution of 1035 lines (1035i). The Japanese MUSE (Multiple sub-nyquist sampling Encoding) system, developed by NHK Science and Technical Research Laboratories (STRL) in the 1980s, employed filtering tricks to reduce the original source signal to decrease bandwidth utilization.
Japan is forerunner of hdtv in the world. Japan terrestrial broadcast of HD via ISDB-T started in December 2003.
The hdtv transmission in Europe started in 2004. Euro1080 is the pioneer in hdtv transmission in Europe. Australia started HD broadcasting in January 2001.
CHUM Limited's Citytv in Toronto was the first hdtv broadcaster in Canada and CBC (Canadian Broadcasting Corporation) officially launched hdtv programming on March 5, 2005.
Mexican television company Televisa experimented hdtv broadcasts in the early 1990s, in collaboration with Japan's NHK.
The hdtv specifications are defined by the ATSC in the United States. An hdtv-compatible TV usually uses a 16:9 aspect ratio display with an integrated ATSC tuner. Lower resolution sources like regular DVDs may be upscaled to the native resolution of the TV.
The hdtv services were made available in the Republic of Korea in 2005 and Brazil is expected to go for it in 2006.
There are numerous online sources carrying volumes of info on plasma hdtv, lcd hdtv, hdtv antenna, hdtv receiver, dlp hdtv, hdtv cables, hdtv tuner etc. Scores of sites are offering hdtv reviews, hdtv articles and hdtv news that are very helpful for the potential customers to buy hdtv.
Now that you’ve chosen what size HDTV to get the next question is what type of technology you should look at. Older CRT analog televisions were all based on the same basic technology, but now you have a potentially confusing array of choices: LCD, plasma, DLP, LCoS, and D-ILA. LCD and plasma are both flat panel technologies that can be mounted on walls. If you’re looking for an HDTV less than 42 inches then LCD is probably your best choice. Plasma is a better choice for HDTVs over 42 inches, as current LCD units get very expensive in larger size formats.
I just pre-ordered the new Samsung HLS-5087W 50 inch rear projection DLP HDTV. Many believe that DLP technology offers the best price/performance in the 50 inch plus category of HDTV today. Sony has made a large investment in LCoS technology which it brands as SRXD, while JVC brands their LCoS line D-ILA. LCoS (Liquid Crystal on Silicon) is most similar to DLP (Digital Light Projection) technology, however many believe the DLP camp has made faster progress on reducing manufacturing costs to offer consumers a better price/performance ratio. While rear projection DLP HDTVs lack the flat panel appeal of LCD and plasma units, they are much lighter and have far less depth than the CRT televisions of the past.
You’ve chosen the right size and technology for your new HDTV, and now you’re trying to understand what is 720p versus 1080i versus 1080p. Let me help you out here – don’t bother getting a 720p today. I’d recommend at least a 1080i, better yet a 1080p. My new Samsung is both 1080p input as well as output. In order to understand what all of these strange numbers mean, well, you’ve have to wait until my next article.
CRT TVs
While it may not be as high-tech as a Plasma HDTV screen, you can still get a big screen TV with the Cathode Ray Tube (CRT) technology (small cathode ray tubes that produce color to create images), also known as direct-view televisions. CRT is the basic technology for televisions that everyone is familiar with and is most commonly available. While they are bulkier and do not have the same image quality as the newer technologies, CRT screens still provide good color, have a long life, can be viewed in brightly lit rooms, and are available for decent prices. CRT screens exist in wide screen and flat screen options. CRTs are built to last, with picture quality that does not fade. A CRT is a good economical choice. However, when Plasma HDTV becomes less expensive in the future the CRT TVs will probably become extinct.
LCD TVs
Liquid Crystal Display (LCD) screens consist of two polarizing transparent panels with a liquid crystal solution in the center that is in a state between solid and liquid. LCD is flat and lightweight, which makes the LCD technology popular for laptop and even some desktop computer screens. The biggest detriment of this type of TV is its limit in size (about 40 inches). The LCD screen is a good choice if you are not interested in getting a large screen.
Plasma HDTV
Plasma HDTV is one of the best and most impressive technologies in the market right now. The plasma screen consists of tiny gas plasma cells that are charged at exact electrical voltages to make a picture. It uses a digital technology that has a higher resolution than the CRT TV screens. The Plasma screens can be produced to have the resolution to watch HDTV. As of now, Plasma HDTV is still superior to LCD screens in displaying blacks which means it has better contrast and picture. They also have better viewing angles than the LCD screens.
The Plasma HDTV not only gives you superior picture quality but it is also smooth and sleek. These screens are flat and light (but not quite as light as the LCD screen) and can be hung on the wall like a picture and are not limited in screen size as the other models are. However, this new technology is still very expensive.
Projectors
Projectors, although not technically a television, are a popular way to get the big screen experience. Quality projectors will give you a good picture and they are excellent for watching movies or playing games. However, you need to have a blank wall or screen and lights have to be dimmed or off to watch it since the projector’s light is dim.
With a better knowledge of the CRT technology, LCD Screens, Plasma HDTV, and projectors you can make a better decision on what type of big screen TV you want to have. With so many choices it is important to know what you are selecting from. If you are serious about your television watching experience, than you will want to get Plasma HDTV for your next big screen TV purchase. This will give you the sharpest image out of all your choices.
Recently TV’s have got wider and thinner, but have they got any better ?
Sure, the latest trend is HDTV (High Definition TeleVision), promising stunning picture quality, but at a much higher price than regular CRT (Cathode Ray Tube) Televisions.
Have a look online, or in the electrical stores and you will see a massive quantity of High-def televisions available. Buzz words like plasma, rear projection and LCD will roll off the salemans tongue and then you will have to choose from a variety of screen sizes, shapes and brands. It's enough to make you give up before you even start looking for the perfect compliment to your Sony PlayStation 3 videogame console.
So what exactly is HDTV then ?
Putting it simply, it's all about small dots. Any television picture is made up of dots of colour. The smaller the dots, the more vivid the images will look. That is why HDTV images look great.
Why do HDTV cost so much ?
Currently we are still paying a premium price because the technology is new and cost a lot of money to develop. The reason for this is that the colour dots that make up the picture have to be 9 times smaller on the HDTV. This makes them very expensive to build.
The PlayStation3 is similar in that it cost a huge amount of money to develop, but Sony can afford to sell the PS3 console at a gross loss, purely because Sony know that the average owner will spend an additional $100 + on very profitable games and accessories for their next-gen games machine. HDTV manufacturers do not have this option, so we pay more until the development costs are covered.
So Do I need a HDTV for my PS3 ?
If the question was ‘will my PS3 only work with a HDTV’, then the answer is no. The PlayStation 3 comes bundled with a cable that will let you use a regular television, however the picture quality is so much worse than a HDTV that is makes your PS3 games look only slightly better than PlayStation 2 games.
If you are happy with a small screen, then the alternative is to hook your PS3 up to a computer monitor. You will need a special cable, and a monitor with a digital input, but this will work fine. If your monitor doesn’t have speakers, then you will need to buy some.
If you want a screen larger than 22 inches, then definitely get a HTDV, but make sure it has at least one HDMI connector on the back and has a resolution of 1080i or 1080p and a screen refresh rate of 8ms or less.
It is natural for us to be initially attracted to the big names in the industry, the brand name does its thing and most of us a captured in a loop that is going around buying one of the big name HDTV sets, this does have some logic behind it, since big companies usually have outstanding customer service and the warranty and guarantees that they provide are, most of time, excellent. You will also find that big names cost big money, and that you can always cut costs of electronic equipment by going to the lesser known company, or a “no name” company, but in this case of looking for a high definition television set you will need to think about your choices carefully, simply because this technology is not yet available on the really mass manufactured level.
There are a few things that could make your decision making process a little more structured, you will need to give up your impulsive feeling and the rush to buy kind of attitude if you want to make this purchase a reasonable one, and many think that this is a way to save a lot of money, and avoid many mistakes.
So when you start looking for a HDTV think about a few shops that you can visit and see some of the HDTV models, think about places that have those TV’s on display and that they are plugged into cable or satellite television so you can actually see how the HDTV looks like while a real HDTV show is on. In any place that you will look for HDTV you will need to take a few minutes and simply watch the screen, so be prepared to politely ask the sales people to give you some space, and let you just watch the TV does it own thing.
There is no real need for all the technical mambo jumbo that usually less then ten percent of the shoppers actually understand, and there is even less need for you to ask the person telling you about the technical details what does he mean, since you can always go back home, log into the internet and find the real answer from someone who is less biased about your next purchase.
While you watch the TV you can ask if the shop has any DVD’s that you can see, since this is almost surely the highest quality available and a very good way to see the ultimate output of the television set, if you are thinking about a few models and the shop has those on the floor, ask to watch the same DVD in all the models you are interested in. Remember that these shops are designed for television sets to look as good as possible, so this will not be the case in your living room, but if all things are equal you will stand a good chance of seeing with your own eyes which HDTV you like best.
Another option is the "S-PVA" feature which allows you to watch the screen easily no matter how you are angled in front of the TV.
Although all TV’s aspire to reach 100 percent of the color array of the National Television System Committee Standard, at 92 percent, the LN-s4692d surpasses most of the televisions in the market today which are usually around 73 percent. In this way, you are able to enjoy a highly detailed and realistic picture.
HPs5033 is another television under the new line of Samsung HDTVs. This plasma TV has a feature called the Gen-5 that addresses the issue of the glare on a screen when in a room with bright lights. With Gen-5 you can get a clear picture not matter how bright the lighting is in the room. And the HPs5033 is able to display more than five hundred and forty nine billion colors so you get a very detailed picture.
There is also an improvement to the design that should be pointed out. Unlike other TV’s where you have to move the whole thing to get to the A/V input the HPs5033 A/V input is on the side of the TV so you can disconnect and connect without the hassle.
Finally, the sound quality on this model is increased with the addition of the SRS Trusound XT. With this feature, no matter where you are in the room you get the same level of sound.
The TX-s27794 could be designed for consumers who are concerned about space. This compact 27-inch screen TV can fit many small or awkward positions in a home. And its size doesn’t take away from the sound and picture quality at all. In fact the TX-s27794 comes with the SRS HDTV system installed. This ensures you the level of sound anyone with a plasma TV has come to expect.
These are only a few of the models in the new HDTV line from Samsung. There are more to see and no doubt in the future Samsung will have a variety of models with new additions and features that will top what it has managed to do today.
HDTV antenna hype created a huge misconception with regard to TV antennas used for HDTV reception. This article is an attempt to clarify this issue.
Do you know what a regular antenna is? Antenna is a piece of metal designed to resonate at a specific frequency and to be responsive over a certain range of frequencies. TV antennas are designed to work either in the range of Ultra High Frequencies (UHF), Very High Frequencies (VHF) or both. Any station transmitting in the VHF/UHF frequency bands, can be picked up by a VHF/UHF antenna and transferred to the TV set.
All television broadcasts, digital and analog, are in the VHF and UHF bands. Over 90% of the HDTV broadcasts are in the UHF, and less than 10% in the VHF band. What is important from the antenna perspective is that HDTV falls in the bandwidth of a regular VHF/UHF antenna. Not HDTV antenna, not HDTV optimized antenna, just a normal regular TV antenna. What makes a signal to be HD is its content, the way a signal is modulated, and not the carrier frequency it is transmitted on. On the contrary, the antenna knows nothing about the signal modulation and content. Hence, you don't need an HDTV antenna to pick up the HD signal. An antenna has absolutely no idea what the signal resolution is. It can be HDTV, SDTV, NTSC, whatever. It is the job of a HDTV tuner and HD television set to demodulate the signal and to present the actual content on the screen.
Well, the antenna bandwidth and frequency response are not the only parameters that are important for clear TV reception. An antenna has other important electrical and spatial properties, such as antenna gain (directivity) and high front-to-back (F/B) ratio. One might assume that an HDTV antenna should be more powerful in terms of F/B and gain parameters. Does HDTV reception impose more stringent requirements on antenna gain and F/B ratio?
There is a wrong, yet widespread belief that you need more antenna gain to receive digital television. I don't know where the hell this belief comes from, cause the situation is exactly the opposite. HDTV has much better noise and interference immunity than the analog television and can produce high quality video at significantly lower signal-to-noise ratios.
Another important specification, F/B ratio, has to do with the antenna ability to cope with a multi-path signal propagation from the towers to the receiving antenna. The higher F/B ratio is, the better is multi-path rejection (also known as ghost suppression). Without going into technical details, we must say that HDTV signal is a bit more sensitive to multi-path cause it has slightly larger bandwidth. Multi-path causes dips in the signal spectrum, whereas we want to keep the spectrum as flat as possible. When signal content is spread over a larger portion of spectrum it is more likely to be distorted by multi-path. Basically, what TV equipment manufacturers are trying to do in the so called HDTV optimization is to keep the spectrum flat in the whole frequency band. It is important for HDTV antenna to have a high F/B ratio in some areas where ghosts may be a problem. The point is, however, that most directional, old fashioned and cheap TV antennas have F/B ratio good enough to handle multi-path propagation of HDTV signal and keep spectrum distortion at minimum. If an antenna can handle an analog signal, it can handle a digital signal as well.
There is nothing specific about a TV antenna that is used to receive HDTV. When choosing an HDTV antenna, check the really important parameters such as directivity, gain, F/B ratio. These specifications are important for reception of both, digital and analog broadcasts. The HDTV optimization is probably the least important factor you should take into account.
A new production and transmission equipment at the DirecTV HDTV station and even a new equipment for reception for DirecTV HDTV is required by the consumer. The strongest selling point for DirecTV HDTV is the higher resolution picture. After media's perfect show up about DirecTV HDTV, the DirecTV HDTV has reached to all the electronic stores. The higher resolution which produces crystal clarity, as never seen before through picture tube, gives us a life like picture and digital sound. A usual TV gives us an effective picture resolution of about 210,000 pixels whereas in the highest resolution DirecTV HDTV format, each picture contains 2 million pixels. This nearly gives us ten times more detailed picture. The basic aim behind DirecTV HDTV is not to increase the definition per unit area but it is rather that the visual field percentage contained by the image should be increased. The proposal about all DirecTV HDTV was first submitted by General Instrument Corporation on May 31, 1990
By December 1990 ATRC also launched the same followed by Zenith and AT&T and the MIT. At present Japan is the only country which broadcasts DirecTV HDTV services to the viewers. The number of converters and receivers sold to the customers has reached to 100,000 and 30,000 respectively. The possibility of starting a digital satellite HDTV service in Japan has been eliminated by the establishment of the analog broadcast service, DirecTV HDTV. Right now, many stations do not broadcast HDTV program.
Slowly, the current analog TV can be either replaced or a new set-top box can be purchased for converting the digital signal. While purchasing any TV receivers we should first ensure that the new receiver has all the input jacks that match the connectors on the VCR, cable boxed DVD player etc.
We should always go in for a composite, S-video and component video as a minimum set of analog jacks so we can use our existing analog equipment with a new set.
The use of digital signal is what separates HDTV from your common television set. The reason why there is such a notable difference between the two is that conventional televisions operate on analog signal. Digital signals are much faster, meaning images are is refreshed more rapidly, therefore providing superb picture resolution. Analog signals are much slower. As a result, the images produced by a television using this type of signal are of low resolution. Simply put, the picture is just not as sharp and view is restricted.
Not only do HDTV's offer superb picture quality, but HD sound is second to none. This is because Dolby Digital surround sound comes standard with HDTV. So, not only does watching an HDTV remind you of a movie theater, it also has the sound system to further enhance the experience.
Along with better quality picture and sound, HDTV's are quite easily integrated with your computer. They are able to easily communicate directly with one another through the use of a type of data compression software such as MPEG-2. Once this software is successfully installed, a whole new world of multimedia technology is literally at your fingertips! For instance, CD-R applications can be transmitted to an HDTV, as well as HDTV programs can be downloaded onto your computer. Either way, the picture resolution is top notch and the signal is stable.
Lastly, HDTV's are more affordable than one might assume. There are many different ways to buy or finance an HDTV system. Some companies offer money-saving offers both in-store and online. Some of these include rebate programs; others include special deals, extra gifts or incentive packages offering items such as hundreds of dollars in gift cards. There are both in-store and online promotions as well as savings with shipping and delivery. Bottom line, HDTV is affordable for almost any budget and well worth every penny!
Other Things to Think About in Buying a HDTV
These days there is a plethora of electronic outlets that have sprouted in U.S suburbs. As well, there is an overload of information dealing with the latest improvements in HD and Plasma TV in newspapers and magazines. HDTV is simply the next generation of digital TV. HD stands for High Definition, and anyone who has viewed HDTV will tell you the viewing experience is far better, especially seeing athletic events or Hollywood productions. So, if your a TV addict then there is nothing today that can satisfy your cravings more than an HDTV.
Among the other considerations you should pay attention to are audio, connector ports, HD receiver/tuner, and, finally, resolution. With regard to audio, top of the line is Dolby Digital Surround, but there are different types worth a look. The best choice is to try out various audio systems before choosing which is best for you.
Also take into consideration how many connector ports you’ll require. The number you can use will vary from brand to brand and model to model. The best way to go is to be certain that there are enough to furnish all your needs. In most Cases you’ll require connector ports such as Composite Video, A/V, RF, RCA and Component video along with HDMI and VGA.
Next, you need to ensure that your HDTV includes an internal HD receiver which will enhance your viewing experience. Of course, some satellite and cable TV providers will provide these for rent, or even give you a free external HD receiver.
Resolution, The Final Arbiter
Finally, don’t overlook resolution, which, in the final analysis is the most critical. If resolution is not up to standards you will not go home to a significantly better television viewing experience, which is the whole objective in the first place. Otherwise, you could have simply continued with your old television. At the very least there should be a vertical resolution of not less than 1080i and 720p which, of course, is much better than what standard television models provide, that is only a single resolution of 480i.
In time, more and more programming for HDTV will evolve. Already, such channels as Discovery and ESPN have adopted it, and the networks in many metropolitan areas are viewable on HDTV. It's a good idea to have the equipment in place to take advantage of this truly enhanced way of watching the tube as it continues to grow.
This new HDTV TiVo has many similar features to it from the TiVo Series 3. It comes with dual ATSC tuners and CableCARD support. The previous version had quite a few items on it that displeased many a consumer and critics alike. So we can all sat good-bye to the THX certification, the 250 GB hard-drive and the front OLED display.
TiVo decided to lessen the amount of space on the hard-drive for the new HDTV TiVo. What the company found was that many of the customers simply were not going to use 32 hours worth of content. Plus this amount of hard-drive was really helping to drive up the cost of the unite. So TiVo decided to take down the size of the hard-drive to 20 hours. In my opinion you really don't need to worry about the size of the hard-drive. 20 hours on the new HDTV TiVo is plenty!
Some of the other more noteworthy features on the new HDTV TiVo are the direct downloads from movies and Television services. This should prove to be the gateway for more services to start being offered in an "On-Demand" basis. Other key offerings include the ability for online scheduling of your HDTV TiVo and music and image streaming for your own computer!
If there is one complaint that I still have with the original TiVo is that the $13 a month subscription fee still applies. I find this amazing as TiVo is really trying to compete with companies such as Dish Network who are stealing away TiVo's customer base. I would have hoped that the level of competition would have done away with this.
In any case, overall I giver the new HDTV TiVo a thumbs up. The pros of the new DVR far outweigh the cons.
I sincerely hope this article has been informative for you.
Adding full high definition capability to your HDTV upgradeable TV is simple, but you'll need to keep a couple of points in mind. In order to receive HDTV broadcasts, you will need a special antenna. With HDTV on DIRECTV, you'll require a special satellite dish. And of course, you need to purchase a specialized receiver. Similar to a conventional cable box, an HDTV receiver is connected directly to your HDTV upgradeable set and used to switch channels.
When you're choosing an HDTV receiver, make sure you get one that will work well for you now, and in the future. Here are a few features to keep in mind:
Affordability
You may have noticed that many of the most reputable manufacturers are now producing high definition televisions at prices the average consumer can afford. HDTV is no longer the luxury it once was, and virtually anyone can enjoy the benefits of high-definition technology. If you find yourself with a little extra cash to spend, consider giving the new gold standard in home entertainment a try. It's a decision your whole family will applaud.
Big, Big Picture
If you're a sports fanatic or a movie buff, you'll want to experience the complete theatre and stadium experience. In this case, an HDTV with a very large screen of over 59 inches is for you, and it can be yours for under $2,000. The RCA 61-inch HDTV Projection Television is available at http://www.dmartstores.com for $1,877. If you're looking to go even bigger, consider the Toshiba 65-inch Flat Screen Projection TV, available from http://www.ibuyplasma.com for only $1,644. Sharp, Hitachi, Philips, Mitsubishi and Zenith all make HDTV sets with similarly large screens that can be found online for under $2,000.
Shopping online will not only save you time, but can also save you a good deal of money. From the comfort of home you can easily buy inexpensive HDTV accessories. A quick Internet search will find satellite receivers like DIRECTV. Look for brand names that offer superior quality and great warranties, like JVD, Toshiba, Hughes, Mitsubishi, Sony, Hitachi, Zenith, Pros can, Panasonic and Samsung SIR-TS360.
HDTV receivers are designed to deliver the highest resolution, and will display video from VCRs, DVD players, satellite and cable TV, game consoles and any other video source.
Network shows are broadcast in HDTV format in almost every major city. You may have noticed the "Simulcast in HDTV" logo at the beginning of some of your favorite shows like C.S.I. DIRECTV offers an all-HDTV channel called HDNET, an all HDTV channel. With DIRECTV, you can also watch shows like The Sopranos on HBO in high definition. There is a good selection of HDTV programming available, and more is being added all the time.
HDTV can bring your television viewing to a whole new level, but you need to do your homework to make sure it's a pleasurable and successful level. Shop around and you will find a great quality high-definition television at a good price.
Rear Projecting HDTV
Currently there are two types of Rear Projection HDTVs. The older Rear Projection HDTV is based on the CRT technology while the newer one is based on the LCD/DLP/LCoS Projection technology. Like HDTV CRT, Rear Projection CRT offers large wide screens at a very low price point. However, you have to deal with poor picture quality from non digital signals, expensive maintenance, bulky cabinet enclosures and narrow viewing angles. The newer LCD/DLP/LCoS Projection technology offer larger screen sizes, good black levels, larger viewing angle, and great picture quality. However, with this technology you have to deal with expensive bulbs that have to be replaced every 5,000-7,000 hours.
Plasma HDTV
The Plasma HDTV is a mainstream technology for viewing high definition channels. Plasma HDTV displays offer amazing color definitions, large viewing angle, good black levels and they occupy less space. However, with this technology you have to deal with the possibility of screen burn-in problems and screen glares.
LCD Flat Panel HDTV
The LCD Flat Panel HDTV is the other mainstream technology for viewing high definition channels. LCD HDTVs offer wider range of screen sizes (7” to 65”), greater image resolutions, are very bright, no burn-in problems and last very long (60,000+ hours). However, with this technology you have to deal with poor black levels, small viewing angle and a high entry price point.
Firstly, HDTV stands for High Definition Television, it uses more pixels on your television screen therefore giving you a better quality picture.
Without going in to all of the technical specifications, with the use of more pixels you are able to see more vibrant colour, and better viewing of moving footage.
To view HDTV you are going to need a HDTV ready plasma or LCD television set. To ensure that your television can pick up the necessary signals you need to make sure you have either a HDMI socket (High Definition Multimedia Interface) or a DVI socket (Digital Video Interface) usually sited at the rear of the TV, and a set top box.
HDTV is not a totally new thing to everybody, Belgium were the first country in Europe to experience High Definition Television, Japan, USA, Australia, Canada, Brazil, China and South Korea are currently enjoying the benefits also. In the USA many programmes are broadcast in HDTV.
The benefits that you are going to enjoy by viewing HDTV are many and the cost of enabled televisions are dropping all the time so soon everyone can participate!
You will be able to enjoy watching crystal clear widescreen images, with stunning true to life colors, if you have Dolby 5.1 surround sound speakers you can also enjoy real cinema quality sound.
There is amazing quality graphics for video gaming, but currently only compatible with the Xbox 360, although future gaming consoles will be compatible.
Soon there will be a new DVD format called Blu-ray Disc, which will allow us to watch and record in high definition.
So the conclusion is that, HDTV is a better and brighter way of watching television and includes benefits for video gamers. With more competition on the market, enabled televisions are really coming down in price making it more accessible to all.
Generally HDTV is broadcast digitally, i.e. together with cable, satellite, or a digital receiver. You cannot view HDTV with an analogue aerial.
There are three things you need to be able to view HDTV and these are firstly a source, such as a local, cable or satellite HDTV station. Secondly, a way to receive the signal, like an antenna, cable or satellite service, and finally an HDTV set.
For the set you can choose from an integrated HDTV, which has a digital tuner, also known as an ATSC tuner, built in. If a station near you is broadcasting in HDTV, you can attach an antenna to an integrated set and watch the station in high definition. Or you can purchase an HDTV-ready set, also called an HDTV monitor, which does not have an HDTV tuner. HDTV-ready sets often have NTSC tuners, so you can still watch analogue TV with them. Your picture quality will still be better than on your old TV, but it won't be high definition until you get an HDTV receiver.
Once you've picked up your set and installed it in your home, you'll need to get a signal. To get a signal, you can use:
An antenna - Depending on your location relative to the stations you want to watch, a small antenna may suffice, but otherwise you might need a rooftop or attic antenna. You can buy an antenna that's specifically made for digital signals, but any reliable VHF/UHF antenna will work.
Cable - Remember that digital cable is not the same as HDTV. Check with your provider to find out which packages include HDTV stations. You'll also either need a set-top cable box or a CableCARD™ to allow your television to receive and decode the cable signal.
Satellite service - As with cable, check with your provider to find out which plans and stations use HDTV signals. You may need a different satellite dish and tuner to receive HDTV signals via satellite.
Many people are not aware that by the end of this year, from what I have read, all TV signals will be sent via HDTV format. In order to watch TV you will either need a HDTV or you will have to have a converter to attach to your existing TV. The converter will not make your current TV an HDTV all of a sudden, it will just allow you to continue to get the same picture you have always gotten. Those converters are going to go for roughly $250 or so, based on my past research.
Now you are considering buying a HDTV, I have convinced you, right? How do you decide which kind to buy? There are regular tube TV’s that are HDTV ready. There are LCD and plasma TV’s. Budget will be a major factor in determining which one to buy. The tradition tube style TV’s are cheaper and they will also fit some existing entertainment centers. The flat screen TV’s will need to be mounted on the wall or most likely require a different kind of base than the entertainment center you currently have.
I did a lot of research before buying my TV. I ended up buying a 42” Sony LCD projection TV. It is a beautiful picture. I am very pleased with the purchase. But, none of these TV’s is without flaws. This particular model has a bulb that helps to project the image to the screen. It has a shelf life of about 18 months. I have had it replaced recently. The bulbs are a couple hundred dollars. Thankfully I purchased the maintenance plan when I bought the unit. Other than that I couldn’t be more satisfied. I can turn out all the lights in the room and throw in a DVD and it is better than going to the movies. I do have mine hooked up to a home theater system. Without that the sound would not be good enough to compare to a movie theater.
Some of the issues with the other kinds of TV’s are: the tube style TV’s are not as compact as the flat screens obviously. They do not get as big as the flat screens. I think the biggest I have seen is 36 inches. Because they are so much cheaper than the other two styles that is all I could think of as problems for the tube style TV. Plasma TV’s on the other hand are the worst buy of them all, in my opinion. My research discovered that plasma TV’s eventually burn out. Whatever is used inside the screen to project the image burns out and cannot be repaired. So, your picture will progressively get worse and you can’t do anything about it except wait for it to get so bad you need to buy another TV. This is a major problem given the price of these types of TV’s. They are the most expensive of the three types. There is no doubt they look nice when you first buy them. They look great in the room you put them in. They are very appealing to most people.
No matter what kind of TV you end up buying the bottom line is that you are going to be amazed the first time you watch your favorite show or sporting event in HD. It is actually funny to me when I look back and think of what TV’s I used to watch when I was little. We had those knobs that you could hear being turned down the street. No remotes, no cable or satellite, and we had to constantly fiddle with the rabbit ears to get a decent picture. I watch a program in HD and I sometimes wonder to myself how they are going to make watching TV in the future even better. It doesn’t seem possible but you know it is. History has shown things only continue to get better.
HDTV seems like a completely new innovation but actually the system has been around in various forms since the mid-1970s and has developed quite an impressive history.
During the 1970s and 1980s, the trial product for HDTV was being developed in Japan as a way to improve television quality and therefore sell more TVs. The first HDTV system was called MUSE and employed filtering tricks to reduce the original source signal to decrease bandwidth utilization.
The idea of introducing HDTV in the United States was met with mixed responses. In the 1980s, the National Association of Broadcasters in the United States invited NHK, Japan’s public network, to present the ideas behind the MUSE system to the Federal Communications Commission. At that time, there were two groups that were adamantly against the introduction of HDTV in the U.S.
The first group that opposed the introduction of this new technology was the Terrestrial Television Broadcasters. They were scared by the possibility of being excluded from the HDTV market because HDTV required more bandwidth (the amount of information sent through a channel or connection) than standard TV. These broadcasters worried because the channels that they already had license to would not be able to handle the bandwidth of this new form of television.
The other group that became concerned about HDTV in the U.S. was Congress. Congress felt threatened by the many Japanese innovations that they saw arriving in the U.S. and ultimately they didn’t want to introduce a new form of communication that was owned by another country all together.
With these two complaints in mind, the American government sought to invent a new form of HDTV. Groups of researchers and manufacturers were gathered together to form different teams. Each team would attempt to create an HDTV system that could fit into the existing channels that were used by broadcasters.
After years of work, the separate teams of researchers and manufacturers decided to combine forces. This unity gave birth to a new group known as Grand Alliance.
As researchers continued their attempts to develop this new form of HDTV, they discovered that this new technology would have to be partially digital in order for all the necessary information to fit into the existing channels. With this in mind, they were able to develop a system that was quite different from the Japanese system. The Japanese NHK version of HDTV was analog but the updated version created by the American researchers ended up being completely digital.
Unlike BETA VCRs and 8-track players, HDTV is one form of technology that is being built to withstand the test of time.
With the decades of development and research that have gone into optimizing the HDTV system, this form of television is likely to endure for decades to come.
The industry is big on hyping HDTV. You may be tempted by the promise of more life-like pictures and crystal clear sound. Even some of your favorite programs will advertise the fact that they are available in HDTV. Maybe you've seen the store ads, or heard friends bragging about their own HDTV sets. If you've been thinking about testing the HDTV waters, this is a great time to do it. HDTV does, in fact, offer audio and video that are leaps and bounds over the quality of traditional television sets. You can easily create the perfect movie night at home with the addition of a good quality DVD player. The best news, however, is that you can now find a wide variety of affordable HDTV sets.
Some television stations have been slow to jump aboard the HDTV train. This type of format change can be a costly undertaking for smaller stations. The equipment alone requires a great deal of financial investment just to make the transition. Television stations need to know that there is a big enough market to justify the expense. In the meantime, we have some local stations broadcasting in high definition, while others continue to transmit analog signals. There are federal guidelines in place, however, and all stations will be forced to comply and make the transition. Considering this fact, it's safe to say that HDTV is here to stay. Until then, digital signals are currently only available through the local stations through a traditional antenna or modern satellite dish.
The first question in making the HDTV transition is whether to buy an analog or digital capable TV. Analog TV is the same basic television service you've used in the past years. Analog signals are sent and received in analog format. This system has been a popular choice for a long time, although the analog TV signals are limited by how much data can be held for the screen and sound. Also, analog signals can easily degrade. It's not perfect technology, although it will still be in use for many years to come, even after HDTV has become the standard format.
HDTV models are known for their wide screens. It may take a little while to get used to the 16:9 ratio, rather than the 4:3 screen you're used to. The truth is, widescreen sets deliver more sports action and incredible theatre-like movie viewing. The screen is nearly twice as wide as it is tall, and you'll see things in your favorite flicks you've never noticed before.
Don't be fooled by imitations. In other words, read the label and the instructions carefully before buying. Some television sets are labeled 'HDTV Ready', or 'HDTV Monitor'. These are not true high-definition televisions. HDTV's have a digital tuner built in, while HDTV-ready sets get their high-definition images either from external sources, like cable boxes and satellite receivers, or from a separate digital tuner (priced at about $350) that hooks directly to the antenna.
These are the basics of high-definition television, although there is much more to learn. Speak to reliable sales associates at a trusted retailer, or do your own research online to learn all about HDTV technology. With the right information, you can be confident in choosing the HDTV model that's best for you.
We've come a long way from those days when the family gathered around a six-inch black and white screen to watch the local news. The incredible sound and picture provided by HDTV brings your family movie night to a whole new platform.
Most major broadcasters are now offering their programming in high definition, and the technology can turn your television viewing experience into a whole new level of cinematic enjoyment, especially in terms of sports events. A large screen high definition television combined with a digital broadcast from your provider mean that you are truly experiencing any sporting event that you may watch for an angle that is arguably even better than attending.
In order to get HDTV into your home, you may have to purchase a special box through your cable company. These boxes can receive and translate the digital broadcast to your television. You can also purchase televisions that are integrated or upgradable to HDTV capacity. The integrated models and upgradables will also require a box or antenna, although some models are available with slots in which you can put a Cable Card, provided your service offers this option.
As might be apparent, a lot of the decision process when determining whether or not to obtain HDTV will depend on your cable service provider. Some providers will offer high definition television only from national broadcasts, while larger local stations will also have HDTV broadcasting abilities. High definition will inevitably present a greater cost to the average consumer, as the receiver must be bought or rented from the service provider. However, most people agree that the clear image and the accompanying sound abilities more than make up for the extra cost of high definition television. Additionally, there have long been plans to fully integrate HDTV broadcasts into all programming. The original goal was to have this accomplished by 2006, however new projections are putting the date at 2009. This does not meant that all analog televisions will become obsolete, as most are able to have boxes attached to receive the high definition signal. Consumers may decide to lessen future expenses that will inevitably occur in the future, however, by purchasing their high definition television now. All HDTV systems available with analog tuners built in, so you will be able to enjoy the full range of programming.
High Definition TeleVision is what HDTV literally means. But high definition compared to what? In order to answer this question, we need to know a bit about the original analog TV system.
Analog TV
30 images per second (in Europe 25) are shown by normal analog TV sets. It does this by writing image lines horizontally, 525 lines in one image (In Europe 625) on the screen. The number of pixels on one line is about 500. This would be a definition of 500 pixels per line by 525 (or 625) lines. Compared to modern computer monitors this is really bad. Even the lowest resolutions monitors have higher resolutions (640 x 480) than an analog TV.
HDTV - High Definition TeleVision
HDTV is high resolution Digital TeleVision (DTV) combined with Dolby Digital Surround Sound (AC-3). There are 18 different formats defined for Digital TV of which 6 are considered to be HDTV.
The difference between Progressive and Interlaced is not difficult. It has to do with how one image is built up. With interlaced technology the odd lines are shown first and then the even lines are shown. The lines are shown in this order: 1,3,5,….521, 523, 525, 2, 4, 6,…. 522, 524, 1, 3, etc. This means that every 1/60 of a second a half image is shown. This often results in flickering, which can be tiring for the eyes.
Progressive technology manages to show a whole image every 1/60 of a second, resulting in a much smoother picture.
How Is HDTV Better?
Normal TV has a resolution of about 210.000 pixels. An HDTV screen has a resolution of upto 2.000.000 pixels, which gives up to 10 times more picture detail.
The aspect ration of normal TV is 4 x 3 (4/3 times wider than high). An HDTV screen has an aspect ration of 16 x 9, which is also known as wide screen.
The Future of HDTV
The FCC (Federal Communications Committee) has mandated that all TV stations in the USA have to be able to broadcast HDTV programs by the year 2006. The mandates of the FCC do not have an impact on just the broadcast companies, but also on cable companies and consumers.
Broadcast companies have to invest on new equipment like cameras, editing equipment, etc.
Cable companies have to convert all of their equipment, including receivers at the homes of their clients.
Consumers may have to buy new equipment, like a top-box to convert digital signals back to analog signals, or even buy a whole new TV set.
HDTV is the future, and a really big step forward. We once started with simple black and white TV, then moved to color TV, and wide screen TV. But all those systems were still based on the same signals as the original black and white TV used. When color TV was introduced it was not possible to force the complete population to throw away their black and white TV-sets and buy a color TV set. Therefore a color TV signal still needed to be understandable for a black and white TV. This prohibited the improvement of picture quality until the age of Digital TV.
The need to satisfy older TV sets no longer exists and the much higher quality HDTV is available via Satellite TV Systems, including Dish Network.
