DIGITAL TV
Digital TV broadcasting began in the UK in 1998, from both satellites and terrestrial transmitters. All digital TV systems depend on data-compression to reduce the bit-rate to a point where it can be accommodated in practical broadcast channels and storage media like tape and disc. DTV only became possible for domestic use when complex and fast processor and storage ICs got down to a low enough price in mass production to make cheap receivers; and when the very complex bit-reduction technology was in place, based on the work of the Moving Pictures Expert Group (MPEG) which established the compatible standards used by the broadcasters and the receivers.
