“Equivalent alternatives for any multimedia presentation shall be synchronized with the presentation.” – §1194.22(b)

Why it matters

Multimedia presentations are possible, if not especially common, in PDF files, primarily via embedded movies and occasionally, via JavaScript effects.

EXAMPLE: A document contains an embedded video demonstrating the use of a product.
RESOLUTION: Closed captioning is added to the file so the dialogue can be read by users with a hearing impairment.

This checkpoint prompts on pages that contain multimedia presentations or scripts (since scripts could load multimedia presentations). If multimedia presentations or scripts are found, the user will be prompted for a Pass, Fail or Not Applicable judgment based on equivalent alternative information (if any) available on the page or in the presentation, such as captions or a transcript.

This checkpoint will be automatically assigned a status of Not Applicable if the page does not contain multimedia presentations or scripts.

FailIf the equivalent alternatives (e.g. captions or auditory descriptions of the visual track) are not synchronized with the presentation.
