HDTV Quality is NOT just in the Program Offerings
HDTV 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
The best way of gaining knowledge about hdtv is by reading as much about it as
possible. This can be best done through the Internet.
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.
DVDs
HDTV is having a huge impact on the home-movie theatre experience. The quality
of HDTV televisions, combined with HDTV movie DVDs 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 DVDs 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 DVDs 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 HDTVs reaches beyond just the fact that they accept digital
transmissions. In fact, most HDTVs 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 HDTVs 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.
