AD Explained
Audio Description is the audio commentary provided alongside digital television services that describes key elements of picture activity for the benefit of blind and visually impaired people.
The service consists of an audio commentary and control signals that allow a suitably equipped decoder to reduce the level of the programme sound when an audio description is received. Further control signals allow the broadcaster to position the sound correctly within the stereo sound field. Both Fade and Pan signals are under the control of the broadcaster.
Audio Description was included as one of the ancillary services in the Broadcasting Act 1996. The ITC has set targets for increasing quotas of audio described programmes on digital services.
