Digital Television (DTV) is a new type of broadcasting technology that is transforming television as we now know it.
By transmitting the information used to make a TV picture and sound as "data bits" (like a computer), a digital broadcaster can carry more information than is currently possible with analogue broadcast technology. The difference between analogue and digital broadcasting is similar to that between compact discs and cassette tapes.
Digital TV therefore offers a better viewing experience with vastly improved picture and sound quality. DTV is also more efficient than analogue TV technology so broadcasters will be able to produce additional signals using the DTV system.
