Are transcripts needed for audio visual material?

In certifying audio and audiovisual material and promotional material on databases, interactive systems and the internet, companies must ensure that a written transcript of the material is available, including reproductions of any graphs, tables and the like that appear in it. In the event of a complaint, a copy of the written material will be requested.

Alternatively, companies may certify material on interactive systems by means of producing an electronic copy, for example, on a CD-ROM or data stick, if the electronic copy is write protected and unable to be changed.
