With Digital Television, sound and pictures are transmitted in digital format by compressing them into tiny bits of information. The signal is then received by a dish or aerial and decoded by a set top box or decoder and displayed on the television.
Digital Television is much more efficient than standard analogue television because of this compression. Therefore it is possible to transmit many more channels on the same space as a single analogue channel. You will be able to receive a much greater range of channels into your home.
The analogue television signal is going to be switched off around 2010. Therefore everyone in the UK will need to convert to digital television before 2010.
