Official methodology to test criterion 3.8

Test 1 (3.8)

iOS and Android
  1. Identify on the screen pre-recorded and live synchronised time-based media that require captions.
  2. Check that the captions are
    • relevant (all important audio information is present, including dialogue);
    • in the language of the video;
    • correctly synchronised. If there is no delay between the spoken word and the appearance of the captions, the captions are correctly synchronised. The reference standard specifies that captions should appear within 100 ms of the caption time stamp.
  3. If this is the case, the criterion is validated.
