Receiver-mixed and broadcast-mixed audio description

Audio description  is delivered as a second audio stream to your television or set-top box, and can be either 'receiver mixed' or 'broadcast mixed'.

With receiver-mixed audio description, the normal audio stream for the program is broadcast, while the second audio stream consists of the audio description narration only, along with signals that lower the sound level on the primary audio stream so that the descriptions can be heard.

With broadcast-mixed audio description, the second audio stream contains both the original soundtrack and the descriptions mixed into it.

Audio description on TV in the UK

The United Kingdom has the most developed and regulated market for audio description, which appears on both free-to-air and subscription TV.

Audio description quotas require a maximum of 10% of audio description on TV depending on the size of the channel, with some exemptions for live programming such as news and live sport. In 2008 the highest level channels reached the full 10% quota requirement for audio description, although a number of them exceeded this.

DVDs with audio menus

DVD discs themselves offer a method of choosing the audio track through the disc’s own menu system. However, these menus vary from title to title and most do not talk, making it difficult for a blind user to select the AD independently. 

Audio menus are DVD menus that narrate the options to a viewer from the moment you insert the disc into your DVD player. They assist you to navigate through the menu options to select the options you wish, including AD. The development of audio menus, also called audio navigation, is still in its infancy both in Australia and internationally.
