When you look at all of the advancements in TV over the half century that it's been part of our lives, few jumps forward are as impressive as the development of HDTV. Sure, there have been a lot of strides forward. TV went from black and white to color. VCR's made it possible to record video directly off of TV signals, and camcorders used similar technologies to make home movies moreaffordable for everyone. Cable TV and satellite TV in turn made TV more accessible and led to the growth of many more channels that people all of over the country now enjoy. Digital video recorders came along to replace VCR's as a more versatile and user friendly technology while most video rentals these days come on DVD. Then, on top of all of these improvements came HDTV.
HDTV is an improvement above and beyond everything else that came before it in a variety of ways. It has a wider screen aspect ratio. That means that movies don't have to be altered before being shown on HDTV and that more detail can be seen with the wider viewing area. The newer prevalence of wider screens has prompted more producers to shoot they're TV programming in 16:9 aspect ratio,and prompted channels to broadcast it in wide screen even if it's not in the HDTV format. The other advantage that HDTV provides is more detail in the form of a much higher resolution TV picture than the old standard definition television format could offer. High Definition Television can have well over twice the number of horizontal lines of resolution that a standard definition television transmission has.
The fact that HDTV is different from standard definition TV makes it so that High Def is a much more information intensive TV format. In fact it can require anywhere between six and ten times the data transmission capability to transmit an hour of HDTV as it does to transmit an hour of SDTV. The fact that satellite TV technology is so much better at moving large amounts of data makes it the TVtransmission technology of choice for HDTV. The satellite TV provider Dish Network has taken full advantage of this fact by being the TV service provider that provides more channels in HDTV than anyone else.
Dish Network currently offers a total of thirty national network channels in HDTV with many more local channels in the High Def format. Given that it's the rare cable TV company that offers a maximum of only twenty two HDTV channels and that the other major satellite TV provider only offers twenty national high definition television channels, Dish Network is in a very competitive position for winningover the majority of HD viewers.
The channels that it offers as part of its programming makes Dish Network highly competitive as well. These channels include everything from high def versions of major network programming to movies and sports in HDTV. There are also plenty of channels devoted to hobbies and other special interests, as well as news, concerts, documentaries, dramas, cartoons, reruns, and much more.
