Sign language interpretation is provided for all prerecorded audio content in synchronized media.

Testing & Remediation

How to test: Navigate to any video content you have on your site and look to see if there is a sign language interpretation is provided. How to remediate: When including video content in your site, provide one of the following:
  • Sign language interpreter in the video. This part of the video should scale at the same rate as the rest of the video (eg if you put the video in fullscreen, the sign language interpreter part also increases in size relative to the size of the window)
  • Provide a synchronized video of the sign language interpreter that can be displayed in a different viewport or overlaid on the the video player

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.
