• What is Digital Television?
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.
• Digital Picture Quality
DTV programs are transmitted in two different formats. The first is Standard Definition Television
(SDTV) and the second is High Definition Television (HDTV).
• SDTV 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.
• HDTV 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.
• Dolby Surround Sound
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.
