Some TV channels have programmes available in multi-channel sound. For example, a programme can be broadcast in German on audio channel 1, in English on audio channel 2 and with an audio description (narration for the blind and visually impaired) on audio channel 3. Which version (e.g. English, German, French or audio description) is available on which channel depends on the TV broadcasting station.
