Official methodology to test criterion 4.3

Test 1 (4.3.1)

  1. Find the synchronised pre-recorded time-based media in the document.
  2. For each synchronised time-based media, check for the presence of
    • either captions;
    • or an alternative version with captions accessible via a link or adjacent button.
  3. If this is the case for each time-based media, the test is validated.

Test 2 (4.3.2)

  1. Find the pre-recorded synchronised time-based media with captions in the document using a <track> element.
  2. For each synchronised time-based media, check that the <track> tag has a kind="captions" attribute.
  3. If this is the case for each pre-recorded synchronised time-based media, the test is validated.

Test 3 (4.3.3)

  1. Find the live synchronised time-based media in the document.
  2. For each live synchronised time-based media, check for the presence of
    • either captions;
    • or an alternative version with captions accessible via a link or adjacent button.
  3. If this is the case for each live synchronised time-based media, the test is validated.
