Official methodology to test criterion 4.1

Find in the document the time-based media (<audio>, <video> or <object> elements) that require a transcript.
For each audio-only time-based media item, check for the presence of a transcript:
- either accessible via a button or an adjacent link (a URL or an anchor);
- or clearly identifiable adjacent.
If this is the case for each time-based media, the test is validated.

Find in the document the time-based media (<video> or <object> elements) that require a transcript.
For each video-only time-based media, check for the presence of:
- an alternative audio-only version accessible via an adjacent link or button (a URL or an anchor); or
- an adjacent alternative audio-only version; or
- a transcript accessible via an adjacent link or button (a URL or an anchor);
- a clearly identifiable adjacent transcript; or
- a synchronised audio description; or
- an alternative version with an audio description accessible by means of an adjacent link or button (a URL or an anchor).
If this is the case for each time-based media, the test is validated.

Find synchronised the time-based media (<video> or <object> elements) in the document that require a transcript.
For each synchronised time-based media, check for the presence of:
- a transcript accessible via an adjacent link or button (a URL or an anchor); or
- or a clearly identifiable adjacent transcript; or
- a synchronised audio description; or
- an alternative version with an audio description accessible by means of an adjacent link or button (a URL or an anchor).
If this is the case for each time-based media, the test is validated.
