Where ICT displays video with audio and shows subtitles, it must show each subtitle within 100 ms of its timecode (20 ms is good practice; untimed subtitles as soon as received).
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.
