HDTV stands for high-definition television. HDTV is DTV at its finest, it has 1080 visible scan lines, most HDTV sets continue to display the 1080 scan lines only as evenly spread up and down the entire screen.
HDTV Truth:
In current practice, HDTV uses 1280 กม 720 pixels in progressive scan mode (abbreviated 720p) or 1920 กม 1080 pixels in interlace mode (1080i). SDTV has less resolution (640 x 480 or 704 กม 480 pixels with NTSC, 768 กม 576 or 1024 กม 576 with PAL in 4:3 and 16:9 aspect ratios respectively), but allows the bandwidth of a DTV channel (or "multiplex") to be subdivided into multiple sub-channels.
The TV stations can use subchannels to carry multiple broadcasts of video, audio, or any other data, and can distribute their so-called "bit budget" as necessary, such as dropping one sub-channel down to a lower resolution in order to make another one available to show a wide-screen movie. Often, this is done automatically, using a statistical multiplexer (or "stat-mux").
Satellite
DTV has been shown to be commercially viable in the satellite television market, where it is used to multiplex large numbers of channels onto the available bandwidth. The business model for satellite DTV in the U.S. and the UK is similar to that for cable TV . Satellite DTV operators tend to act as packagers for large numbers of channels, including pay-TV. The greater radio frequency bandwidth available to satellite operators allows them to out-compete terrestrial DTV operators on both number of channels and picture quality.
