Digital Television (DTV)

Digital Television (DTV) is a form of television broadcast that utilizes digital data and signals to transmit audio and video programming to viewers through cable and satellite transmission mechanisms. Digital television uses compressed digital data for faster transmission. The compressed data must be decoded by the television set, receiver or TV-enabled computer.

DTV takes up less bandwidth than analog TV, enabling broadcasters to provide a greater number of channels, multicasting, digital media guides, interactive services, pay services, and high-definition TV service.
