Where ICT displays video with audio, it must let the user choose any available audio description and hear it on the default audio channel; where the video technology has no separate audio description mechanism, selecting one of several audio tracks suffices. Support for extended audio description is useful.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
