Testing & Remediation

How to test: Watch any prerecorded video content that is present on your site. When there are pauses, visual information or other content that is not understood without supporting context, ensure there is extended audio to describe that information. How to remediate: When posting video content to your site, offer one of the following:
  • A way to turn on & off the extended audio description. This allows users who need the extended audio description the ability to activate it when required.
  • A separate, alternative version of the video that includes the extended audio description content.
