Although the technology that is in fashion this year and will sell more this Christmas is DTT, Digital Terrestrial Television, we can already begin to prepare for who will fashionable next year, HDTV, TV High Definition. Although we already have plenty of available products compatible with HDTV, probably the next-generation consoles will be those that will make this technology take off definitively in our country.

Specifications of HDTV

The most important feature is the highest definition picture offered by HDTV compared with current systems. If the PAL system used in Spain offers a resolution of 768 x 576 pixels, the HDTV can use two different resolutions: 1920 × 1080 and 1280 x 720 pixels, always using the ratio 16:9.

These high resolutions are achieved by sending the signal through a compressed codec as MPEG-2 or H.264. The sound is transmitted with Dolby Digital 5.1 and offers to take advantage of the popular speaker systems of Home Theater.

Differences between 1080i and 720p

Many among you have seen the features of the XBox 360, that supports two different output resolutions: 1080i and 720p. These resolutions are the two we have commented that offers HDTV and indicate the number of lines that can be seen. The i indicates that the signal is interlaced, meaning that in every single frame is drawn half of the lines of the screen (a yes and no), ie 540 lines are displayed every time, switching alternatively. By repeating this process many times and very quickly our brain is able to decode it and we can properly view the images.

The p, in contrast, means progressive, and indicates that all the lines are drawn in the image, one after the other.

Which is better? The theme is a bit subjective, but is recommended for the 1080i images with little movement or movements slow and fast movements that can distort the picture. In return, this resolution provides more detail and a better image.

In contrast, the 720p is more suited to rapid camera movements. For example, in U.S. chains ABC and ESPN use 720p format because it offers better results in their broadcasts of sporting events, where the cameras often have to move at high speed.

How do HDTV Work?

As we commented in our colleague Javier special DTT, this is not the way to see HDTV, as the DTT (at least in the USA) does not provide the bandwidth needed for transmission in high definition across the country at least not yet.

Therefore, most systems will be to see HDTV cable and satellite. In the case of Spain, Digital Plus was doing tests in HD transmission via satellite, while DirectTV intends to deliver through the platform they offer ADSL 2.

Of course, you need a TV that supports this resolution, although many of the new models are already beginning to bear it is advisable to check that the TV that has a buy a HDMI (High Digital Multimedia Interface).

It seems quite doubtful that in the near future we can start watching high-definition television in the USA, at least in a generalized way. For now, the chains are focusing on the transition to DTV and not taking into account the potential of HDTV, so you spend a few years before the system is introduced. At least, we can use our consoles to take advantage of the formats offered by the new televisions.

Nowadays, wide screen mode televisions have become quite popular. Basically, the wide screen mode in television or the wide screen format is considered as the format of the future. The wide screen mode is also called the 16: 9 format. You can get the full benefit of watching this 16:9, if you have both a wide screen television and digital reception.

In a true 16: 9 format or the wide screen mode, the images will naturally fill the screen of the TV without getting cropped or stretched. Also, in the wide screen mode televisions, the programs that are broadcast have wider, better pictures and appear more natural to the eye. Therefore you get a better viewing experience while watching wide screen mode televisions.

Currently, more and more televisions are launched in the markets that have wide screen modes. Wide screen mode televisions allow you to watch a film in a format that the directors intend to be seen. The wide screen display TVs look more like a cinema screen.

There’s no doubt about the fact that the wide screen mode television is the shape of the future for television, and rapidly these will replace the most large screen sets-24 inches and above.

The principle behind the working of HDTV is the digital display mechanism. Whereas the older form of television works on the basic accessories like antennas. The antenna receives the information from the air and displays it through the monitor. Antennas are analogous to the digital television. This is vastly different from the digital mode of display that is found in HDTV. Since digital mechanism is employed in a HDTV, the pictures and sound qualities are vastly improved.

The high resolution enables a clear viewing of the pictures and clearer sound quality. Since in older days, the data was divided into two parts, for picture and for sound, the quality was not so much superior as that of the HDTV. In the digital HDTV, such is not the case. Here, the image and sound are not fragmented. Therefore, the quality of sound and picture are excellent. Moreover, there is proper synchronization between the picture and the sound. Sometimes, in the older generation television, such synchronization was a thing to dream of. Therefore, it is a vast progress in the field of television viewing and motion picture.

Perhaps, due to the vast change in the technological process, the HDTV has made its mark. People are now trying to see the digital television instead of older day television for more pleasure. Herein lies the success of HDTV.

Getting a TV in today’s market really means understanding that the appliance that you buy will not have a very long life. By this I mean that sure it will last forever, sometimes, but really because new technology keeps an exciting pace, there is really no stopping what will become obsolete and what will remain a fresh and novel bit of machinery.

This means that as consumers we must keep abreast of the changing technologies. New terms and the gadgets that go along with them are not easily understood. This is similar to the acronym HDMi.

It was recently announced that all televisions would need to be transferred from analog to digital cable in the coming months. Original cable would be eliminated and television would be given a fresh look. For this, HDMI has come in and begun the conversion.

HDMI, also known as High Definition Multimedia Interface, is the first form of digital audio/video interface. It is currently the only product that provides high quality digital service with only one cord. Replacing analog media, HDMI supports all currently available media formats with multi-channel digital audio and high-definition video. It gives users a crystal clear home theater experience by eliminating additional cords and reduces the chance of a fuzzy picture with no clarity. And, not only does HDMI connect audio and video on PCs to those on televisions, but it is the only creation that delivers media to HDTV’s and digital PC monitors.

To get a handle on the market, HDMI has been implemented by Hitachi, Phillips, Sony, Panasonic, RCA, and Toshiba. It has also been used to support Fox, Disney, Warner Brothers, and Universal as they produced major motion pictures. This year alone, over 200 million HDMI products will ship from one of the many founding companies.

Understanding where and when to locate and buy these products will make the true difference.

If you buy when the product is in BETA, it will be expensive and have a lot of bugs despite the new tricks that it can do. This was made very evident with Windows Vista, which cannot break out of its shell to this day. So we suggest read this blog daily to get more information on breaking technology and how to use this to your Advantage.

Here are the benefits of Blu Ray Technology:

1. Can be made compatible with normal CDS and DVDS to be played.
2. Blu Ray Disc violet laser carries a shorter wavelength than the standard red laser allowing greater precision.
3. The Blu ray disc permits data to be stored in less space, so it’s possible to hold more data on the same size hardware.

Using your blu ray disc TV allows you to see and watch more movies and shows in greater definition and better sound quality. The blu ray disc completely complements the new type HD TVs that are excellent in reception quality and even better when playing regular DVD’s.

Here are a few recommended High Definition Televisions:
