Abstract
digital television is a completely new way of broadcasting and is the future of television. With
the advent of digital technology, digital audio and video compression and other advanced signal processing, it is possible to transmit and receive broadband data over co-axial cable and through satellite and terrestrial. digital television is a telecommunication system for broadcasting and receiving moving picture and sound by means of digital signals, in contrast to analogue signals in analogue (traditional)television. It 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. For all delivery mechanism a digital set-top box is needed at the customer's premises. It receives the digital transmission and decodes video, audio programs to display on normal television Receiver.
