The current Analogue TV system has been the standard since television began in the 1940s and 50s. Technological advances in the field of computers have allowed television to enter the 21st century producing cinema-like quality and sound in the home.

Digital TV is a new way of broadcasting Television that converts the picture and sound into a binary data stream. Terrestrial Digital TV is transmitted from the TV station on the same radio waves as Analogue TV so that it can be picked up by your existing TV aerial. With the addition of a digital set top box that can read the binary data carried on the radio wave, your existing television will be able to display Digital TV.
