Digital television (DTV) is a new way of transmitting high quality video and audio to your TV set. Using DTV, broadcasters can transmit 

high definition TV (HDTV) images, Dolby digital surround audio, and new services such as multicasting (transmitting more than one 

program on the same TV channel) and datacasting. Several of these services can be combined into a single digital broadcast. 

 

DTV programs are transmitted in two different formats. The first is Standard Definition Television (SDTV) and the second is High Definition 

Television (HDTV).

 program formats include 480-line interlaced (480i) and 480-line progressive (480p) video. 480i programs are essentially a digital 

version of our current analog TV programs, while the 480p format offers improved image detail over 480i. Some 480p programs are 

broadcast in widescreen and are comparable to progressive-scan DVD movies in image quality.

 program formats include 1080-line interlaced (1080i) and 720-line progressive (720p). Both HDTV formats are always broadcast 

in widescreen, and offer much higher picture quality than SDTV.

 

With DTV, you can listen to a variety of Dolby digital audio formats from Dolby Surround 2.0 to Dolby Digital 5.1 surround, using your 

home audio system. Many HDTV programs are now broadcast with DD 5.1 soundtracks.
