Test 1 (3.4)

iOS and Android

1. Identify on the screen video-only time-based media with an alternative (text transcript or audio-only version).
2. If the text transcript is present, check
   • that it is relevant (all important audio or visual information is present, including dialogue and embedded text).
3. If there is an audio description, check
   • that it is relevant (all the important visual information is present);
   • and that it is correctly synchronised (the audio description soundtrack coincides correctly with the video).
4. If there is an "audio only" version, check
   • that it is relevant (all important audio or visual information is present, including dialogue and embedded text).
5. If this is the case, the criterion is validated.
