Digital switch over is the process of changing the UK’s television broadcasting to digital. This involves converting the current television broadcasting network, as well as ensuring the public has upgraded or converted their TV equipment to receive digital television.

This process involves the replacing the analogue terrestrial transmissions network that has been in place since the 1930s with an all-digital terrestrial network. At the moment digital and analogue signals are broadcast simultaneously. But whilst the analogue signal is maintained, the digital signal can't be broadcast in full and at full power across the UK.

Switch over will affect all viewers who have any televisions through which they can only receive analogue services BBC1, BBC2, ITV, C4/S4C and (where available) Five through the TV aerial.
The switch over process will take place region by region over five years, starting in 2008.
