HDTV - Quality is NOT just in the Program Offerings
from: George PhillipsHDTV has, without a doubt, become the wave of the future in the United State. The FCC has mandated its use by broadcasters, videogame manufacturers are taking advantage of its sound and picture clarity, and many consumers are chomping at the bit to get a hold of this latest technology.
Broadcasting Channels
Most people only think about television offerings when it comes to HDTV. True, all of the major television stations, ABC, CBS, Fox, NBX, and PBS, now transmit in HDTV. In addition, many of the big names in cable and satellite, including HBO, ESPN and Showtime, also broadcast in HDTV. Despite the facts that all of these networks currently broadcast in HDTV, there are still a number of programs that are not in HDTV. This is, however, likely to change as the FCC works toward making the change from analog broadcasting to digital broadcasting. Nonetheless, the advantages of HDTV reach beyond just the television programs being offered.
DVD’s
HDTV is having a huge impact on the home-movie theatre experience. The quality of HDTV televisions, combined with HDTV movie DVD’s is outstanding. Most current movie CD’s come in HDTV and in Dolby 5.1 surround-sound. Even older movies are being digitally re-mastered and include HDTV and Dolby 5.1 surround sound. The digital sound and picture placed on these DVD’s combined with the HDTV television’s ability to decode the digital technology combine together to form an unbelievable home-movie experience.
In addition, HDTV televisions are set up in true widescreen format. For this reason, movies can be viewed in the way the filmmaker intended them to be seen. Watching a movie in widescreen on an analog television, on the other hand, produces irritating black lines at the top and the bottom of the screen.
The combined technology of DVD’s and HDTV televisions has caused many people to say that watching television in this way is like looking through a window because it is so crisp and clear. This, combined with the realism brought on by surround sound, is an excellent way to make movies come to life.
Video Games
HDTV is also the way to go for people who enjoy playing video games. The soon to be released X-Box 360 and the PlayStation 3 have both integrated HDTV technology into their gaming systems. Both Microsoft and Sony have claimed that the graphics and sound of video games will be much clearer and enjoyable for those gamers who have HDTV televisions.
In addition, HDTV tube televisions are a much better choice for video game junkies than plasma televisions. Plasma televisions can experience color burn, which are images that are permanently “burned” into the screen, from video games. This is because certain visuals from video games remain on-screen for extended periods of time.
No matter what an HDTV television set is used for, the resolution of all programs, movies, and video games will be better using an HDTV. This is because the quality of HDTV’s reaches beyond just the fact that they accept digital transmissions. In fact, most HDTV’s are set up to receive analog transmissions, as well. But, for even these analog transmissions, the picture is clearer on an HDTV.
The reason the picture continues to remain clearer on an HDTV television, even when a program is not transmitted in HDTV, is because of the pixels in an HDTV.
Most HDTV’s come with either a 1080i resolution or a 720p resolution. For the 1080i resolution, the “I” stands for interlaced. This term is used because the lines of the television are actually interlaced to form a clear picture. With 1080i resolution, 30 frames of interlaced resolution are transmitted at a time. First, the even lines are transmitted, then the odd. This pattern continuously repeats every second. In all, 1080i resolution provides 1920 x 1080 pixels, for a total of 2,073,000 pixels.
In 720p resolution, the “p” stands for progressive. With 720p resolution, 60 frames of resolution are transmitted every second. The resolution of 720p is of 1280 x 720 pixels, for a total of 921,600 pixels. Many people feel this provides an even clearer picture than the 720p resolution, though HDTV televisions are capable of decoding both resolutions. Since HDTV’s have such a large number of pixels, they can create a clearer picture, even for programs that are not broadcast in HDTV.
Important Notice Concerning DTV and HDTV: Although many TV systems have already complied with earlier rulings for changing all transmission to digital TV, there still is doubt as to when overall compliance will be reached. Earlier it was scheduled for late 2006, but it is doubtful if this happens.
