G68: Providing a descriptive label that describes the purpose of live audio-only and live video-only content


Applies to all technologies

This technique relates to:


This technique provides a descriptive label for Live audio-only and live video-only content. This label may be used in combination with an alternative for time-based media for audio or an alternative for time-based media or audio description of the video. Those alternative however are not part of this technique. The purpose of this technique is to ensure that the user can determine what the non-text content is - even if they cannot access it. NOTE: Even if full alternatives are also available, it is important that users be able to identify the non-text content when they encounter it so that they are not confused, and so that they can associate it with the full alternative when they encounter it.


Example 1


Resources are for information purposes only, no endorsement implied.



  1. remove, hide, or mask the non-text content

  2. display the text alternative(s)

  3. check that the purpose of the non-text content is clear - even if content is lost.

Expected Results

If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
