HDTV Info - Purchasing Tips

2008-07-05T09:31:00.001+02:00

When looking for HDTV info for purchasing decisions you may feel that you will never get your head around the technical aspects of this area. So what do you want in your HDTV info gathering quest? You may start with an idea of what you want born from an in store demonstration or admiring a friends system at home. Whatever the initial reason there are esentially three things you will need for your HDTV info options.

*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 ie 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.

HDTV Antenna Reviews

2008-06-25T06:07:00.001+02:00

Read on for some information on the various HDTV antennas available.
HDTV antennas have become a very important part of the home entertainment system. The main reason behind this can be attributed to the razor sharp quality of HDTV broadcasts. As a matter of fact, the quality of the HDTV broadcasts is normally better than what you see on your television sets through a paid satellite subscription. As the over the air (OTA) HDTV is free of charge, you can get a HDTV antenna installed at your house and take the best advantage of the amazing quality of the broadcasts. Before you think that an HDTV antenna is a complex piece of equipment that costs a small fortune, let me clarify that is a regular TV antenna that is used for HDTV reception.

Although there are many antenna reviews available over the internet, it is important to understand that the HDTV antennas are different from most of the other products regarding the information of what is good and what is not as the performance of a HD antenna depends on the specific location that it is placed on along with other factors like the distance from the network tower, presence of any reflecting objects near the antenna and in case of indoor HD antenna’s the materials used in the construction of the building also plays an important role. Hence, it is quite common to find many contradictory reviews of the antennas. It is highly possible that a particular antenna may be perfect for one user but absolutely useless for another user. Hence, while deciding on which HDTV antenna to purchase, along with reading the reviews, it is more important to read a HDTV antenna buying guide or other related articles.

Indoor HDTV Antenna Vs Outdoor HDTV Antenna

Indoor HDTV antennas are usually more popular as they are very easy to install and also cost far less when compared to outdoor antennas. However, the indoor antennas have to be placed very close to the television set which is usually at the same level as the television itself. This lack of elevation along with possible distortions produced from walls, furniture and other items present in the house usually inhibits the performance of the antennas. Hence, the indoor antennas are ideal only when they are in close proximity to local transmitters along with minimal topographical and structural obstructions.

Outdoor HDTV antennas are usually considered to be the best antennas even though they incur high installation and basic costs. Further, the harsh environment also takes its toll on the antenna. They are ideal for reception in remote areas where the transmission towers are very far.

Directional HDTV Antenna Vs Omni-Directional HDTV Antenna

An omni-directional antenna is used when the conditions to receive the signals are good and also the signal is strong. It also provides the advantage that one does not have to worry as to which direction the signal is coming from. A directional antenna on the other hand is a requirement where the signals are weak. Here, if two signals coming from two different directions have to be picked then either two different antennas or an antenna rotator is required.

Outdoor UHF HDTV Antenna Vs Outdoor VHF Antenna

Unless and until the HDTV programs are broad casted on the VHF bands in your area, the VHF antennas should be avoided. These antennas are comparatively very big in size, much more expensive and very difficult to install. A UHF/VHF antenna can be bought but this is always a compromise and the performance will be comparatively deteriorated on each band especially the VHF band. There is also the option to buy UHF and VHF antennas that are stacked together. But these antennas too have the drawback of being very big and expensive along with innumerable installation hassles.

If you are new at buying antennas then it is better to inquire in your neighborhood as to what is the best option available. I agree that cost can play a major factor but you should plan long term and buy wisely. You could also ask the dealer to give you a trial run of the various antennas that you have in mind so that you can work out what works out best in your area. Buy wisely.

New HDTV DVD Technology Challenges Existing Formats

2008-06-13T09:23:00.000+02:00

As if the format war between the HD DVD and the Blu-ray high def DVD formats wasnâ€™t heated enough, there will likely be another player coming into the ring in the immediate future. A virtually unheard of company called New Medium Enterprises is set release its own high def disc format which it calls HD VMD.
Unlike Blu-ray and HD DVD, HD VMD takes advantage of existing red laser technology to read the data off of the discs. This use of an already established technology makes the HD VMD technology much cheaper than HD DVD or Blu-ray. In fact, while HD DVD players are stuck around three hundred dollars a piece and Blu-ray players have only recently dropped below five hundred dollars, HD VMD players will probably cost about a hundred and fifty dollars when they first hit retail stores like Costco and Radio Shack. In addition to lower cost players, the discs themselves should cost less too. HD VMD discs are expected to cost significantly less than either of the two established formats (if you could call two formats that are in the middle of a bitter and protracted format war established) and slightly more than conventional DVDâ€™s.

Before anyone gets too excited about being able to watch movies in high definition off of a disc, it should be pointed out that there are still very few titles available in the HD VMD format. In fact, there will only be about twenty titles that come from the United States and most of them will come from smaller independent studios- including one owned by Mel Gibson. In addition to those twenty American titles, there will also be a variety of foreign titles including Indian movies from Bollywood.

Of course, there is a considerable amount of skepticism about the possibility of a small start up company coming out of nowhere to take down the best efforts of two massive companies like Toshiba and Sony. This is especially difficult to believe when you consider the fact that Blu-ray and HD DVD are both backed by some pretty major motion picture studios, but that doesnâ€™t mean that itâ€™s impossible. After all, the ability to buy a player for half that of the nearest competitor and less than a third of the price of the other nearest competitor can be pretty attractive to consumers and the big companies ultimately have to give the consumers what they want. There will be a lot of economic pressure to release movie titles on HD VMD.

At this point the technical details of the HD VMD format still aren't very clear, but there are a number of things that we can guess about this new format. First of all, since we know that HD VMD is based on the same red laser technology that conventional DVD's and CD's are based, we can guess that an HD VMD disc can't store as much data as Blu-ray or HD DVD discs which are both based on blue violet laser technology. This is a reasonable guess because of the fact that a blue violet laser has a shorter wavelength and can therefore encode more information, more finely onto a disc than the longer wavelength of a red laser can. This might not actually be much of a problem when you look at the fact that a Blu-ray disc can store far more data than an HD DVD can, yet they can still both be used for HDTV movie storage.

Only time will tell how this challenge to the big HDTV DVD formats will play out, but it could be a case where more primitive technology vanquishes more advanced technology because of economics.

The Coming Age Of HDTV - What Does It Mean To Me?

2008-06-05T05:23:00.002+02:00

HDTV - high definition television: it is something that has been discussed for some time now, however not everyone has a strong sense of what it is and why he or she would want to have it.

Because all television stations will be required to broadcast a digital signal after February 17, 2009, many viewers are beginning to ask a lot more questions about how the new digital age of television will affect their personal viewing experience. They want to know whether or not their television set will be compatible, whether or not they will have to replace it, and what steps they will have to take in order to keep watching their favorite shows.

How To Identify If Your Television Is An Analog TV

Analog television has been with us since the inception of television broadcasting. Analog is the old way of processing a television signal.

Television technology took a big leap in the 1960's with the transition from television tubes to circuit boards, but that conversion failed to bring with it any major strides in the quality of the television picture.

If your current television does not have a logo on its front that indicates DTV (Digital TV), EDTV (Enhanced Definition TV), or HDTV, then your television set is an analog TV.

Understanding The Transition From An Analog Signal To The New Digital Signal

Digital image processing is a technology that began in earnest during the 1970's, when Japanese technology companies began to explore the concepts of HDTV. The Japanese TV manufacturers were exploring ways to improve the picture quality of the television image, as a way to find more customers for their television products.

While Americans were busy playing with building the computer industry, the Japanese were hard at work trying to build a better television set. The first HDTV systems developed by the Japanese still relied on the old analog system of sending a broadcast signal to their televisions, but they were still able to produce a better television viewing experience.

When initially introduced to the U.S. Government, the new HDTV system produced a myriad of concerns, which included the issue of an analog HDTV-system needing more bandwidth than what was currently allotted to the television broadcasters.

In 1993, a consortium of American researchers and manufacturers (known as The Grand Alliance) joined forces to find a way to bring HDTV-quality to the American public, while keeping the bandwidth requirements of broadcasters within the existing limits.

Researchers soon understood that they would need to push at least part of the television signal in a digital format to make sure that HDTV could be transmitted within the limits currently allotted to the television broadcasters. By the time they had finished their work, the Grand Alliance had created a system that was 100% Digital.

In 1995, after considerable opposition from the television broadcast industry, the U.S. Federal Communications Commission officially set the standard for completely digital HDTV broadcasting system. This put into motion the events that are just now coming to fruition, with the rollout of the new Digital Television broadcasting system.

Although most television stations have been broadcasting a Digital Television Signal now for a few years, analog television owners have been none the wiser. But that will all change on February 17, 2009.

Will My Analog Television Stop Working In 2009?

The simple answer is "yes", but that does not mean that you will have to buy a new television in order to get the new digital broadcasts. While you may not need to replace your television set, you may have to make changes in how you get your television signal.

There are in fact three ways that the average consumer can continue to get a television signal using their old television set:

1. Subscribe to a cable television service (and use their digital television converter);

2. Subscribe to a satellite television service (and use their digital television converter); or

3. Buy a DTV converter (Digital TV Converter) to receive signals from your analog antenna and to convert that signal back to analog, so that you can continue to use your analog television. (If you receive your television signal over-the-air, the Federal Government has implemented a Coupon Program to help consumers offset the cost of the DTV converter boxes: http://www.ntia.doc.gov/dtvcoupon/index.html )

Understanding The Three Facets Of The New Digital Technology

1. Lines Of Resolution

The newer digital technology is all about Lines Of Resolution. With more lines of resolution, the viewer will receive more image information, therefore bringing the viewer much more picture clarity and detail.

When the Japanese rolled out HDTV on the Japanese mainland, the lines of resolution numbered 1080. To put this into perspective, the standard analog TV signal exhibits 330 lines of resolution. This makes it more than clear that the original analog HDTV format really was a real issue for television broadcasters in the United States. To produce a resolution of 1080 lines on a system designed for 330 lines would have literally required three times the bandwidth of the current analog system.

Here are the standard television resolutions:

* Analog Television - 330 Lines of Resolution

* VCR's - 240 Lines of Resolution

* DVD's - 480 Lines of Resolution

* EDTV - 720 Lines of Resolution

* HDTV - 1080 Lines of Resolution

There is a caveat to this chart though. The minimum requirement of the FCC is that broadcasters must produce a minimum of 720 Lines of Resolution. As a result, some broadcasters like ABC chose the 720-resolution, and yet they can still legally call their programming standard, HDTV.

Other broadcasters like PBS opted for the higher 1080 format. Good for them.

In 1998, when the first HDTV's became available to the buying public, the Headline News newscasters were joking that with the rollout of HDTV, we the audience would be able to see every blackhead and blemish on their faces. Of course, they were probably correct in that assumption. The detail of the HDTV-signal is absolutely amazing.

2. Aspect Ratio

Another factor connected to the new HDTV-format is the Aspect Ratio.

In a standard analog television, the Aspect Ratio is a 4-by-3, which nearly looks square. The 4-by-3 ratio means that it can be measured 4-parts wide to 3-parts high.

With the new HDTV format, the Aspect Ratio has been changed to the same format seen in the movie theatre - a 16-by-9 Aspect Ratio, or 16-parts wide to 9-parts high.

3. Sound Quality

The third factor connected to the new HDTV-format is Sound Quality. In fact, most HDTV programming will carry with it Dolby Digital 5.1 surround sound, as frequently heard on DVD's. So long as you have a surround sound unit attached to your television set, the surround sound will enable to the television viewer to be immersed in the sound, so much so as it often feels as if you are in the middle of the action happening on your television set.

In Conclusion...

While it is true that you do not need to upgrade your television from the analog format to the new digital format, you might seriously consider doing so anyway.

Now that we are quickly approaching the end of the analog-television era, the cost of HDTV television sets has fallen considerably. Whereas five years ago, the average HDTV cost in the range of $3-4,000, the cost of most HDTV's has fallen to under $1200 today. After February 17, 2009, the cost of HDTV should drop again, making it much more affordable to the general public.

Although it will be possible to convert the digital television signal to analog, you will lose the extra picture detail on the conversion. So, if you stick with your analog television, you will be restricting yourself to the quality of picture you are currently receiving, even after the change in television broadcasting formats is complete.

Although color-technology was first introduced to audiences with the release of The Wizard Of Oz in 1939, color television did not become mainstream until the late-1960's. And although the technology of color was mainstream, black-and-white televisions were still being manufactured and sold well into the 1980's.

Fortunately, this transition will be a bit quicker than the conversion from black-and-white to color. Under the FCC rules for the transition to digital television, television manufacturers were required to include a digital tuner in all television sets manufactured after March 1, 2006.

This conversion is much like the transition from AM to FM as the standard listening medium in the radio industry. Radio listeners could not listen to FM stations until which time they had upgraded their radio from AM to the AM/FM format. The same thing will happen here as well. If you want to receive the beautiful, high-quality HDTV images, you will need to upgrade to a television set capable of displaying the HDTV images.

If you have any lingering doubts about the better HDTV standard, all you need to do is to visit your local television store and see for yourself just how awesome of a picture HDTV actually produces. Just as Dolby Digital Surround Sound enables the listener to feel as if they are in the middle of the action on the television, HDTV permits the viewer to feel as if they are standing in the same room as the actors, on the sidelines at the football game, or on the same beach as the models - it really is that good of a picture.

Do You Understand High Definition TV?

2008-05-27T09:17:00.000+02:00

Perplexed with HDTV?
Recall when there was just TV. Now we've got SDTV, EDTV, 480i, 480p, 720p, 1080i and 1080p. Enough to make you sick! And if you think you are befogged now, just go communicate to any electronic megastore and you will get what true confusion is all about. Let's address basics. You want the finest picture you can get for your money...that's a gimme. Getting there is actually easier than you imagine. Reading the rest of this article will give you some of what you demand to make an knowledgeable judgement when shopping for an TV. There are over 250 million televisions in the United States. Video signals pump information into a TV at the rate of 30 frames per second. Each frame is a still impression that gives the appearance of endless motion, just like a cartoon. I could go on here but lets leave it at the basics.
High Definition Television does two things. Firstly, it increases the amount of scan lines on the display. Second, it widens the aspect ratio of the display from the standard 4:3 to 16:9. The wider screent format has a more theatrical look. HD TV format is 1080p, or 1080 lines interlaced. An alternative format is 720-lines progressive scan, or 720i. Though it has fewer lines, the native progressive scan format eliminates motion artifacts that originate in interlacing, and are still apparent in large screen 1080i. The bottom line is that 1080i and 720p are both excellent formats. One is not better than the other; they are just each better with particular types of material. When done correct, both HDTV signals are clearly superior to orthodox 480-line format we have today.
High Def. coming sooner than you think
Everyone crosswise the country will have to make a choice on Feb 17, 2009: A government mandate requires that all full-power TV stations cease broadcasting analog signals and exchange to 100% digital broadcasting!! This transformation primarily affect nearly 15-20 million TV viewers who rely on localised over-the-air broadcasts received via antenna. People who fall into this category will have to purchase an hdtv antenna. An antenna will allow you to receive your local HD stations. Antennas come in diverse styles and shapes and are inexpensive, usually around $40 to $50.
The great about an hdtv antenna compared to the old analog antenna is you will either get an HDTV image or you wont. You will not miss ghosting and interference you had to deal with on your old antenna. When you switch to an hdtv antenna you either get the digital image or you don't.

HDTV Receivers

2008-05-17T07:56:00.004+02:00

HDTV (High Definition Television) is an innovative form of DTV for broadcasting TV programs. A HDTV receiver is a specially designed device to decode digital signals and enhance the quality of pictures and sounds of your home theater. The HDTV receivers are also known as HDTV set-top box or HDTV tuners.

Generally, the HDTV receivers collect and decode the signals and display the signals in 1080i and 480i or p format, where, "i" means interlaced and "p" means progressive. The HDTV receiver can also be used to display videos from cable TV, satellite TV, DVD players, or any other video source. The signals transmitted by the HDTV receivers will produce pictures with high resolution and great clarity. Apart from transmitting high quality pictures, the HDTV receivers also broadcast high quality surround sound.

When compared with other DTV receivers, the HDTV receivers come with many added advantages. Some HDTV receivers also come with access cards for security and digital video recorders. The HDTV receivers with digital video recorders can store programs up to 30 hours or 200 hours.

Though the HDTV receivers provide high quality picture and sound, they are highly sensitive to multi path distortions and more over, the HDTV receivers are very expensive and programming are limited. In spite of the downsides, there is a big demand for HDTV receivers, and a great competition in the HDTV receiver market. Today, the US market is filled with countless domestic and foreign brands of HDTV receivers. Mitsubishi, Thomson, and Samsung are some of the leading brands in HDTV receivers.

With the advance of technology, the HDTV television sets are coming with inbuilt receivers. But still, there is a great demand for external HDTV receivers. The HDTV receivers are quite expensive and the cost of a HDTV receiver will range from $300 to $1,000.

HDTV receivers can be purchased from any of the local stores, dealers, wholesalers, or online shops. Among these, an online shop is the best option for a wider choice in different types, brands, and price levels of the HDTV receivers. Carefully selected, HDTV receivers will allow you to enjoy your favorite television program with high resolution and surround sound.

Which HDTV Should You Buy?

2008-05-16T09:10:00.001+02:00

HDTV's Surging Popularity

This year alone sales of HDTVs is expected to reach 20 million. In fact, HDTV sales is on track to post a one week record shortly before the Super Bowl, as fans to want to enjoy the big game in all of its high-definition glory. HDTV comes in different prices and sizes. Whether it is DLP, LCD and Plasma. Consumers are confused on what to buy because of their unfamiliarity with the technology.

Studies show that nearly 60% of HDTV buyers are not sure on the difference between LCD, Plasma and Micro Display. Many HDTV shoppers do take time to research but still need to be guided on which product is appropriate for their demands and budget.

Cable companies have strengthened the demand for HDTV, as there is already 17 channels that offer HD programming. In addition, HDTV prices have sharply dropped over the past year and some sets cost as lows $1,500.

Comcast has reported that its roster of HDTV customer agents has ballooned to 1,100 and they answer queries and take orders from subscribers. The company has also deployed 1,100 HDTV technicians to assist in setting-up the products at homes.

Terminology of HDTV

HDTV - a new breed of TV that combines the capabilites of a HD-tuner and HD-ready display. Nearly all of HDTV’s being sold in the market today use the 16:9 widescreen aspect ratio. An HDTV tuner can receive analog and digital broadcasts over-the-air.

HD–compatible TV- only composes the high-resolution display. Can only accept digital broadcasts if hooked with a separate HDTV tuner. HD-compatible TVs can have the 16:9 widescreen ratio or the square-ish 4:3 aspect ratio.

Starting on HDTV

A recent study by the Consumer Electronics Association indicated that 71% on consumers it has surveyed plans to purchase an HDTV set soon are already planning and saving up. However, one reality in the consumer market today is that store do have the right number salespeople that have a good grasp on new technoliges.

Most are more concerned on making a quick sale rather than making it easy for the consumer to understand what he is going through. Translating or explaining complicated technology terms is never an easy task.

It's hard enought to expain the difference between HDTV and analog TV and it will be more complicated to clearly tell the difference between HDTV and EDTV.

Setting up HDTV

When you decide to jump into HDTV give yourself time to become familiar with the technology. An HDTV setup normally consists of the following, HD-ready TV, receiver, antenna and HDTV service provider. Many HDTV's nowadays already have a built-in tuner, eliminating the need to purchase an independent box.

No Such Thing As an HDTV Antenna!

2008-05-14T07:17:00.002+02:00

Why HDTV broadcasts can be received with a regular TV antenna and HDTV antenna is just a marketing spin.
Over-the-air (OTA) HDTV becomes more and more popular. For someone who is used to noisy analog TV pictures, it is hard to believe how amazing a quality of HDTV broadcasts can be. In fact, HDTV channels received over the air free of charge often have better quality than the same channels received through a paid satellite HDTV subscription. All you need to enjoy OTA HDTV is a HD television with a built-in HDTV tuner and an HDTV antenna.

Huh? Which kind of antenna?! If you have Ph.D in Electrical Engineering and have never heard about the antenna type called "HDTV antenna", it's not because you were a bad student. HDTV antenna has nothing to do with physics and engineering. It was invented in marketing departments. Marketing found an effective trick to boost TV antenna sales. HDTV is a hot thing these days. Call essentially the same device HDTV antenna, and it sells better. It makes people to believe they must buy an HDTV model or HDTV optimized antenna to watch HDTV broadcasts. This is very far from truth.

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.

Shopping For An Hdtv

2008-05-10T09:29:00.000+02:00

There is an option to greatly enhance your television viewing; high definition television. The resolution offers amazingly lifelike pictures that make you feel as though you can reach out and touch the picture, itself. Many people have found the joy of owning an HDTV, but others are confused by the number of options available. What is the best option to choose? Is plasma better, or should they choose LCD or DLP technology? To help you make a little more sense of the market, here are a few tips.

Plasma: Plasma offers one of the best pictures on the market, today. However, there are a few drawbacks. It is one of the oldest technologies, for starters. Plasma televisions also generate an enormous amount of heat; they can get hot enough to be painful to the touch, in fact. There is also the question of burn in on the screen itself. Many plasma televisions have a lifespan of about 5 years, though newer models offer a longer lifespan.

LCD: LCD technology has been around for a long time. LCD televisions offer a great picture, though they cannot attain the same clarity that plasma televisions can. That said, they stay cool to the touch and can last for a very long time. These are some of the most reliable options in the HDTV market.

DLP: DLP is a relatively new technology that uses a projector and millions of microscopic mirrors. The picture quality with DLP is wonderful; however, they do have a few drawbacks. The projector in the television usually burns out in a few years, necessitating a replacement. Many manufacturers actually include projector replacement instructions in the box.

Regardless of which HDTV you choose, you will have to purchase HD programming from your television provider. This will be in addition to any other channel package that you currently have.

Satellite TV Provides HDTV Channels

2008-05-06T07:37:00.001+02:00

There are several different things that you can do in order to get the best picture possible when it comes to home entertainment. The first thing that most people will think to do is to get an HDTV set. While this is a positive step in the quest for a better TV picture, the purchase of an HDTV set alone won't provide a better TV image. In fact, without taking the necessary steps to ensure that a new HDTV set is able to function optimally, it may actually give you a worse picture than you're used to. The reason for this is that HDTV is a television format rather than a type of TV set, and the HDTV set is simply the device that's needed in order to view that TV format. While an HDTV set can display normal TV content, the resulting picture may not look as good as it does on a normal TV set. That's because of the way that an HDTV set is able to display a higher quality picture. An HDTV screen is made up of a lot more individual pixels so that more detail can be packed into each frame. Normal TV programming doesn't provide the instructions of what to do with all of those extra pixels, so they remain unused and the result is a grainy low resolution picture. In all fairness though, this result will be much more apparent on a larger HDTV screen than it is on a smaller one simply because a larger HDTV screen makes it easier to see any kind of defect in the picture.
While knowing the reason why normal TV doesn't look as good on an HDTV screen may be enlightening, you're probably wondering what you can do in order to remedy the situation. The solution is actually fairly simple and goes back to the fact that HDTV is a new TV format. In other words, you need programming in HDTV format in order to get the high quality picture that your HDTV set is capable of. You can get HDTV programming in any way that you can get normal TV programming- over the air, cable TV, satellite TV, off of an optical disc, or downloaded from the Internet. Out of all of these options though, satellite TV is the best for delivering HDTV.

First of all, HDTV is extremely data intensive to transmit, so it requires a lot of bandwidth. Satellite TV technology has a surplus of bandwidth, which makes it ideal for transmitting lots of HDTV channels. Satellite TV providers such as Directv have taken advantage of this fact by providing a plethora of HDTV channels to their subscribers. It also provides the specialized receiver equipment necessary to process an HDTV signal.

While HDTV is available from other sources, the high bandwidth requirements exaggerate the problems of those other mediums. For example, there aren't many normal TV channels available over the air, and there are even fewer HDTV channels. Normal TV takes forever to download from the Internet and HDTV takes even longer. Cable TV has severe bandwidth limitations, and HDTV channels use up that limited bandwidth even faster.

Hopefully, this article will set you on the road towards getting a TV picture that's truly better.

Updating My Home For HDTV Viewing

2008-05-05T06:06:00.001+02:00

Recently, I decided to change my home office because it was in dreaded need of organization and décor. I know what I want in a work station, I just have never taken the time to sit down and think it all out. The first things I knew I needed were a new desk, desk chair, bookcase, and media station. I had a set budget of what I wanted to pay and truly didn't want to surpass it. I went to Office Depot and Office Max to see what I could acquire.
All of the furnishings totaled up to be more than what I wanted to spend. I ended up searching the internet to see what I could acquire. I was able to go through a company located in New Jersey that sold several of the same furnishings in Office Depot and Office Max for much less. I was glad to be able to get all of the stuff I needed without even coming close to my budget. Once I got all the essentials, I wanted to work on the media area of my home office. I savor listening to music and having the tv on in the background while I work. I wanted to buy a new stereo and an HDTV if I could afford it.
I headed out the door to Ultimate Electronics to see what I could find. The first thing I looked into was the sound system. They were pricy so I started looking at the iPod players. They weren't so much money and would fit my needs so I purchased one. Then I browsed the high definition televisions. The pictures on HDTVs are out of this world. I knew I wouldn't be watching much of it while I worked but how could I get anything less than a high definition picture? I had to buy the best.
The HDTV I decided on is only a 32" but I can mount it on the wall, which means it won't take any area. I was so excited to get home and try out my new toys. When I came home, I instantly put up the HDTV and MP3 player. It was as if I had my own personal space where I could do anything I wanted. I turned the TV on and it had the clearest picture I have ever seen. High definition sure is one of the best inventions. At first, I thought my new HDTV and sound system was going to distract me too much but it has actually made me more at ease. I don't hate sitting in my office now...I love it!

Save Hundreds When Buying a New HDTV!

What You Need to Know About HDTV

If you are reading this then I presume that you are either interested in HDTV's or are thinking of purchasing one. Think no more, make the switch now! You might ask why would you want to change your old television set for a HDTV? Well, the main reason is that an old television set does not have digital superiority, and HDTV's are gorgeous to look at!

With HDTV's, digital superiority is one of their many features. The difference is particularly evident when viewing movies. The details are crystal clear and when it focuses on a certain item, that item seems to be magnified for you, as if it is really in front of you.

HDTV's also feature progressive scanning and digital audio. It is completely balanced. You cannot really enjoy the full cinematic viewing experience if the sound is not really clear. Well, there's no need to worry there. With the digital technology, the audio makes you feel as if you are really there, right in the thick of the action.

There are also no more ghost images. By ghost images, we are talking about a certain blur on the things you watch on TV that makes them look like they are ghosts. These can be highly annoying but are a thing of the past with HDTV. You can also watch DVDs in a much better way and with greater satisfaction because HDTV's have a better quality DVD playback.

Common television sets are based on the aspect ratio of four to three (4:3). This ratio means that the television can be measured with an approximation of its height of three feet, and a width of four feet.

However, the aspect ratio of an HDTV is, drumroll please, a whopping sixteen is to nine (16:9). This makes the image an HDTV gives out much much wider! In fact, the screen size of an HDTV is thirty three percent wider!

The width that is increased indicates a huge improvement since it permits you to view tv sitcoms and movies that you like, as if you were watching them in the cinema, just minus the loud snoring guy behind you and the couple that never seem to gasp for air in their kissing spree in front of you!

Just in case you do not know, when you are watching whatever it is that you are watching on a 16:9 screen, you are actually making use of your peripheral vision. The utility of your peripheral vision will definitely make you feel like you are part of the program that you are watching.

The director of ABC's Monday night football, Norm Samat, did a feed about HDTV. And she vouched for the wonder that HDTV's can bring. She said that once you look at the pictures on your HDTV, you would seem like you entered a sort of trance because you actually see more than what is really shown!

Now in terms of football, the sixteen is to nine (16:9) aspect ratio makes a big difference. In the old four to three (4:3) aspect ratio, it was often a very tricky to have all of the action covered on one screen. On a HDTV, they are already in your picture, so you can actually get to see more of the play, and also more of the development of the play.

In conclusion, HDTV is the future and is becoming increasingly popular and commonplace. This also brings a final problem. With new technology comes confusion as to what system you need exactly. With HDTV sets costing hundreds and sometimes thousands of dollars, it is well worth ensuring that you read up what you are buying to ensure that you get the right system for you and not waste your hard earned money! This is where a HDTV Buyers Guide comes in useful. You can get a free HDTV buyers report at: http://www.which-HDTV.info.

Some HDTV Technologies are Better Than Others at Displaying SDTV

2008-05-01T08:57:00.000+02:00

Despite the growing popularity of HDTV and the rising sales of HDTV sets, most of the TV content that's watched on HDTV sets is in standard definition television- the older format that's been around since the dawn of broadcast TV more than half a century ago. There are two major reasons for this. The most obvious reason is that there are still far more standard def channels than there are HDTV channels. In other words, not everything that every HDTV owner wants to watch has made the transition to HD.

The second reason why most of the TV programming that's watched on HDTV sets is still standard def is because HDTV programming isn't nearly as popular as HDTV sets. The evidence for this includes the fact that there are only about half as many households with subscriptions to HDTV programming packages as there are households with HDTV sets. There are several reasons for this. For one thing, HDTV has become something of a status symbol and the HDTV sets are much more evident of this status than having the HDTV programming to watch on them is. Another reason is that HDTV sets have the wide screen aspect ratio that many DVD's and an increasingly large number of standard definition TV shows are available in. The wider viewing area is a good way to heighten enjoyment of watching TV, and in many ways is more noticeable than the high resolution picture that you get with HDTV. Yet another reason is that modern video game systems like the Xbox 360 and Sony's Play Station 3 can display their graphics in high def resolutions and take advantage of the 16:9 aspect ratio of HDTV sets.

Despite all of this, many people find standard definition programming relatively unsatisfying on HDTV sets. There are several reasons for this. For one thing, the analog format that a lot of standard definition TV still comes in, isn't completely compatible with a lot of HDTV sets. This causes a worse picture in many ways than if the same programming was just displayed on a standard def screen. Another problem comes from the fact that HDTV screens are simply designed to display more pixels which result in a more detailed picture than you can get from a standard definition TV set or standard def programming. Therefore, the result of displaying standard def programming on such a high def screen is missing pixels which cause the picture to look grainy and generally low quality. This is especially obvious when standard def programming is displayed on a relatively large high def screen.

There is a way to combat this problem though- buy an HDTV set that's good at rendering standard def programming. There are a variety of sets that are better than average at doing this and they're made in a variety of technologies. DLP projection TV's and Plasma screen TV's can both be good at this, but there are more LCD screen HDTV sets on the market that are well rated for displaying standard def programming than any other type on the market. One thing that will help is getting an HDTV set with a built in up converter that will fill in the absent pixels to make the SD picture look sharper. Barring that, a smaller screen will look better because the gaps in the picture will be harder to see.

In all, this is a problem, but not one that can't be avoided with a little bit of foresight.

Electronic Store HDTV Facts

2008-04-30T17:53:00.001+02:00

Electronic store gadgets seem to sprout out of nowhere like mushrooms. Every time you read a newspaper or magazine and watch the television, you are introduced to the latest and most advanced technological breakthrough on the face of the earth. Of the many gizmos and devices available on the market, one thing that TV addicts may want to consider investing on is the HDTV or High Definition Television.

This new device is a more enhanced version of digital television, or DTV. The resolution in HDTV is more defined and you will truly have a more cinematic experience with this type of television.

However, when buying HDTV, you need to insist on an integrated system because it is complete and you do not have to think about connecting tuner or receiver. With the integrated system, all you need is a satellite or cable connection.

If you do not have enough money, you can probably consider the HDTV-capable set. This is an HDTV monitor but you will need to find or buy an external receiver to enable you to watch an HDTV show or program. It is important to note that an HDTV without this external receiver is just like an ordinary television set. You will not be able to enjoy high definition images even if the monitor is HDTV without this add-on.

By the way, an HDTV ready is not necessarily an HDTV capable screen or monitor. Before buying this type of system, carefully ask your sales clerk if the set is actually an HDTV screen. Better yet, just stick with the HDTV integrated system or the HTV-capable set.

Since there are many brands of HDTV in the market, choosing one can really be daunting. To help you out with this task, read the buying guide below to know what features of HDTV to look for:

Audio

The most common type of sound system used in HDTVs is the Dolby Digital Surround. Some manufacturers, however, use other type of audio systems. The best way to determine which brand has the best sound is to try them out.

Connector Ports

The number of connector ports of HDTV varies tremendously from one brand to another. Thus, if you are buying an HDTV, or any other television sets, you need to see if the product has all the connector ports you need.

The usual connector ports that are being used are the Composite Video, RF, A/V, RCA, Component video, VGA and HDMI.

HD Receiver/Tuner

If you do not want any fuss, you should opt for a set that has an internal HD receiver or tuner. As mentioned earlier, this is the integrated system type of HDTV set. However, if your cable or satellite provider rents out or offers free external HD receiver, then you may want to buy the much cheaper HDTV capable set.

Resolution

One of the most important features that you need to look out for when buying an HDTV is the resolution. If the resolution of the HDTV set is poor, then there is really no reason why you have to buy that set because your old television set may have better resolution.

If you want fantastic resolution, be sure to look for a set that has a vertical resolution of 1080i and 720p. Standard television usually only has a vertical resolution of 480i. By the way, the "i" here stands for interlaced, which is the type of vertical resolution being used in analog TV, while the "p" is progressive, the usual choice for digital television sets.

HDTV builds up popularity worldwide

2008-04-30T17:49:00.001+02:00

HDTV is one technology that does not seem to be loosing steam with consumers. The popularity of this unique viewing system is spreading around the world. With the United States set to move to mandated HDTV broadcasts by the year 2009, and with the same country already restricting the new televisions manufactured in the country to be HD ready, the fascination will only continue growing.

To date, the broadcasters have been hesitant to turn to HDTV. The cost involved has not seemed like the logical choice. With the recent surge of HDTV sets that have been purchased, and with the popularity of sporting programs broadcast in HDTV, it is likely these broadcasters will soon see the error of their ways.

The recent cost reduction of HDTV sets through out the retail market has helped increase consumer interest in the market. Experts are predicting that the prices have probably hit their low mark and will begin to level out. In the mean time, there are millions of set owners struggling to find programming that can do those sets justice.

HDTV veterans will tell anyone who will listen that this viewing is beyond anything that can be experienced. These viewers will demand that broadcasters meet the quality or they will find a way to meet their needs in another arena.

Upconversion Technology Provides HDTV Owners With Alternatives

2008-04-22T06:42:00.001+02:00

HDTV owners are faced with a very real challenge when it comes to figuring out what to watch on their new High Def sets. After all, with only a handful of HDTV channels available from most service providers and and the fact that the high def DVD format war is still very much undecided (though a lot of indications point towards Sony's Blu-ray format coming out on top), it can be pretty difficult to figure out where to get a decent amount of high def programming. At least it's a lot better than it was a few years ago before high def DVD's were available at all, and HDTV channels were even more limited!

There are other options for enjoying and getting more out of an HDTV set though. One good alternative is upconversion. Upconversion is a technique that electronically increases the resolution of a TV image to more closely match that of a real HDTV picture. Basically, an upconverter will analyze an image and add pixels to the picture that are similar to the pixels surrounding the empty space. Put another way, upconversion fills in the gaps in the quality of the picture that would otherwise be left by displaying a standard definition TV picture on a high def TV set. This technology definitely improves the picture beyond what you would get with an ordinary TV picture, but not to the same level of detail and quality that you would get with a recording that's true HDTV.

There are a number of devices on the market that take advantage of upconversion technology. One of the most popular devices is a DVD player that plays conventional DVD's that have a resolution of 480p and bump it up to resolutions that are much closer to the 720p, 1080i, and 1080p that truly count as high definition pictures. Of course the end result won't meet the high level of quality reflected in those resolutions, but they will be close. This type of upconversion that's built into DVD players is a good way to take advantage of DVD's that you might already have- as well as those that you rent- without having to invest in a high def DVD player that may or may not be compatible with anything a year from now.

Another device that takes advantage of upconversion technology is the Vudu. The Vudu is a set top box that takes advantage of your broadband Internet connection to download video in standard definition resolutions and then boost its resolution up to HDTV quality before delivering it to your TV screen. This technique of downloading video in standard def and then upconverting it is certainly a good way to save bandwidth on the network connection, but it really doesn't provide the quality of a real High Def picture. By all accounts it seems that the Vudu's technique is more of a short cut than a way to offer quality.

Another good solution comes in the form of the Play Station 3 from Sony. The Play Station 3 is a video game platform that plays high def movies from Blu-ray discs. The device also has the ability to upconvert normal DVD's and the graphics of older play station video games to high def resolutions. While this does represent an investment in high def DVD technology, it's also a good way to get a variety of entertainment in one device.

Despite the shortcomings of upconversion, it does have a decent amount of potential as an alternative for HDTV viewing.

How to choose the right HDTV antenna for your set-up

2008-04-21T10:27:00.000+02:00

How to choose the right HDTV antenna for your set-up

Choosing an HDTV antenna can be a frustrating business. However, if you prefer to receive HDTV through an antenna, rather than a satellite or cable subscription, there are a couple of things that will make life easier.

First of all, if you can, you should opt a roof or attic mounted HDTV antenna. This will give you the best chance of picking up a good signal and is a must if you a re in an area where signal strength is poor such where you live some distance away from the nearest transmitter or where your signal is affected by hills or other environmental factors.

If an external HDTV antenna is not an option, perhaps because you live in an apartment or in a building of historic interest, then you'll have to go for an internal, set-top antenna.

Unfortunately, every HDTV antenna is not alike and the quality of your picture can vary greatly depending on which antenna you choose. So how do you know which one to go for? Perhaps the best way is to find out from people who already has an internal HDTV antenna, how it works for them. The best way is to talk to people you know - particularly those in the same apartment block. Failing that, user reviews on the Web are a good source.

Amazon sells a number of antennae for HDTV and user opinion on them varies greatly. For example, this Terk HDTVi Indoor VHF/UHF HDTV Antenna gets slated by users, while this Gemini ZHDTV1 HDTV-UHF Digital Indoor Antenna, which is actually cheaper than the Terk, gets great reviews.

As with any item of electronics, the key is to do your research. Find out as much as you can about the HDTV signal in your area, and if possible speak to people locally who are receiving HDTV via an antenna, before you buy.

Defining TV Moments with HDTV

2008-04-18T07:36:00.002+02:00

Television technology as we know it today has evolved tremendously from its inception in the late 1800s. Inspired by the success of the inventions of Bell and Edison in bridging wide distances, scientists became more and more intrigued by the possibility of ‘distance vision’ or the ability to simultaneously see someone in another part of the world moving and talking while one is in another location.

With their relentless efforts, it wasn’t long before American scientist Charles Jenkins and Scotsman John Baird were able to put on air in England and the U.S their first television programming of silhouettes and stick figures. This was followed by several major breakthroughs which eventually led to the development of television technology as we know it today.

• 1927 — Bell Laboratories transmitted the first live picture with voice broadcast.
• 1939 — RCA unveiled its first line of television receivers in its World’s Fair.
• 1943 — The National Television Standards Committee (NTSC) technological standards for black and white TV were established.
• 1957 — Robert Adler invented the first practical remote control called the ‘Space Commander’.
• 1960s — Color television programming was launched.
• 1962 — Television signal via satellite was launched for the first time
• 1970s to 1980s — The highly efficient fiber optic cable was introduced significantly improving delivery of television programming and paving the way for the entry of digital television technology.
• 1990 — Closed-caption television was created for the hearing-impaired.
• 1994 — High Definition Television (HDTV) standards were established along with a plan for the eventual phasing out of analog television and the conversion to the digital format
• 1998 — The first HDTV sets were sold in the market.

What is HDTV?

High Definition TV or HDTV is a digital broadcast standard that insures the viewer the ultimate in viewing quality and sound. It is one of 18 voluntary standards for digital television set by the Advanced Television Standards Committee (ATSC), which provides guidelines on the levels of quality to be followed for sound and video encoding and transmission. Of these 18 standards, which are all superior to the analog technology commonly used in television today, HDTV holds the highest rank. The HDTV broadcast format, therefore, is the most superior. However, purchasing an HDTV-ready TV set does not mean that one automatically gets to enjoy the benefits of this technology. To be able to enjoy HDTV, one must also be viewing a program that has been digitally prepared. In some cases, one needs a set-top converter to convert the broadcasts from analog to digital.

Whatever it is, one cannot escape the fact that the digital age is upon us and, whether or not we are ready, it will just be a matter of time before the analog broadcasts we have grown so used to is phased out and digital TV becomes the standard.

For an avowed TV addict who knows nothing about digital TV, the prospect is daunting. The need to understand DTV and HDTV therefore is now.
