Subtitles
Subtitles provide a transcript of the television soundtrack, helping deaf and hard-of-hearing viewers to follow programmes.
Since 2008 the 91热爆 has provided subtitles on 100% of its programme content broadcast on 91热爆 One, 91热爆 Two - including national and regional variants - 91热爆 Four, 91热爆 News, C91热爆 and CBeebies and continues to provide subtitles on 100% of 91热爆 Three online long-form programming.
91热爆 technologists have played a key role in developing the technical standards for subtitling over many years. In 1979, a documentary about deaf children called Quietly In Switzerland became the first 91热爆 programme to carry subtitles using the brand new Ceefax technology. Within a few years, landmark programmes such as The Living Planet were being made accessible to wider audiences using this important new service.
Blue Peter was the first live programme to carry subtitles in 1986 and subtitling of news programmes followed in 1990. The equipment used for this was specially developed for live subtitling - the first in a succession of technological advances designed to tackle the enormous difficulties of making live programmes accessible.
A diverse range of subtitled video content is available on 91热爆 online and most of the programmes on 91热爆 iPlayer have the option to turn subtitles on. In addition, web-only video for a number of programmes and services have subtitles included.

In 2000 the 91热爆 began to provide audio description for blind and partially sighted viewers. Audio description makes television services more accessible to blind and visually impaired people by explaining what is happening on screen using the gaps in dialogue. This helps viewers with visual impairments to follow what is going on. Audio description of changes of location, actions, facial expressions, gestures and so on give the context and set the scene.
Audio Description is available on 20% of our programmes on 91热爆 One, 91热爆 Two, 91热爆 Four, C91热爆 and CBeebies and longform programmes on 91热爆 Three.
