1.2.1 - Audio-only and video-only (prerecorded)
The intent of this success criterion is to make information conveyed by prerecorded audio-only and prerecorded video-only content available to all users. Alternatives for time-based media that are text based make information accessible because text can be rendered through any sensory modality (i.e. visual, auditory or tactile) to match the needs of the user.
Ways to meet the criterion
Make sure that information conveyed by prerecorded audio-only and prerecorded video-only content is available to all users. Purpose of a transcript varies based on the needs of the user:
- for deaf it provides an alternative to what is presented through audio
- for blind it provides an alternative to what is presented visually
For video-only content, there is also an option to provide an audio track.
