modern television devices that will replace analog televisions and will greatly improve broadcast quality and increase the number of broadcast channels
Digital television (DTV) is a telecommunication system for broadcasting and receiving moving pictures and sound by means of
digital signals, in contrast to
analog signals used by analog (traditional) TV. DTV uses digital
modulation data, which is digitally compressed and requires decoding by a specially designed
television set, or a standard receiver with a
set-top box, or a PC fitted with a television card. Introduced in the late 1990s, this technology appealed to the television broadcasting business and consumer electronics industries as offering new financial opportunities.
