What is digital TV?

Digital technology means television signals can be transmitted more efficiently, freeing up more space for more channels and services.

The signals are converted into a digital format and compressed, allowing several digital channels to be carried instead of a single analogue channel.

Viewers will need to decode the signals with a set-top box or integrated digital TV (iDTV) set.

If you can watch BBC Three or BBC Four, you already have digital TV.
