Guideline 1.2: Time-based Media (part 1)

Provide alternatives for time-based media

You can use this guideline both for time-based media and synchronized media (with another format and/or time-based interactive components), including:

audio-only (AO)
video-only (VO)
audio-video (AV)
audio and/or video combined with interaction (AVI)

(Different success criterion apply for each one. It will be marked)

Examples

Audio Only (Prerecorded): Provide an alternative that presents equivalent information for prerecorded audio-only content.

Video Only (Prerecorded): Provide either an alternative for time-based media or an audio track to present equivalent information for prerecorded video-only content.

Audio in synchronized media (Prerecorded): Provide captions, and if possible, also sign language interpretation.

Synchronized media (Prerecorded): provide an audio description or media alternative

Audio content in synchronized media (Live): provide captions

Video content in synchronized media (Prerecorded): Provide audio description

When there is so much dialogue that audio description cannot fit into existing pauses in the dialogue, provide an alternative for time-based media (Level A)

Don’t forget to embed interactive elements (for example links) in the alternative

Sign language interpretation and extended audio description for synchronized media (Level AAA) are recommended where appropiate
