Where pauses in foreground audio are insufficient to allow audio descriptions to convey the sense of the video, extended audio description is provided for all prerecorded video content in synchronized media.

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.

Questions and Answers

What is Time-based media?

Time-based media is content that must be made accessible when held against criterion 1.2 of the WCAG 2.0 guidelines found here: https://www.w3.org/TR/UNDERSTANDING-WCAG20/media-equiv.html Content is considered time-based media if it's:
  • Audio-only
  • Video-only
  • A combination audio/video
  • Audio and or video combined with an interaction.
This terminology encompasses a broad number of third-party software platforms and content libraries, such as:
  • YouTube
  • Video.js
  • SoundCloud
  • Spotify
Put broadly, time-based media is anything that's embedded on a website that: moves, makes noise, displays content synchronized with another element of the site, or displays content that changes without user input. Certain accessibility considerations need to be made when building content so that everyone has access to content regardless of their level of ability.

How long does the accessibliity process take?

This question depends on a number of factors including size of site, desired level of conformance, your developer's understanding of accessibility techniques, etc. Accessible Web is here to help. Reach out and we can discuss your site specifically.
