Overview
Digital TV transmits a broadcast signal by encoding it as zeroes
and ones to provide new and higher-quality services. It offers an
amazing multimedia experience while providing access to Internet,
voice, and video across the same medium. Digital television provides
crystal clear, "snow-free," and sharper, cinema-like pictures
with CD-quality sound to all TVs that can receive a minimum level
signal. It can be compressed to provide multiple channels (up to
5 channels per program) in the same bandwidth required for one channel
of NTSC television (the current standard).
This system allows transmission of TV programs in wide screen,
high resolution formats known as HDTV
(high definition TV) and SDTV (standard definition TV) format providing
significantly better color performance than existing analog TV systems.
It will be used by more than 1600 broadcast TV stations in the US.
Broadcasters have the ability to simultaneously transmit multiple
video programs using a single TV channel simultaneously delivering
digital data services with TV and audio programming such as publications
(local electronic newspaper), program schedules, computer software,
specific product information, email, and Internet connectivity.
