The short answer would be providing captioning for hearing impaired where audio is supplied and textual description of information provided in video format for visually impaired.

Subject: Meaning of "synchronized media"

Hello --
I have a question about the meaning of "synchronized media", because the terms used seem very specific. This is related to SC 1.2.5 in WCAG 2.0: https://www.w3.org/TR/UNDERSTANDING-WCAG20/media-equiv-audio-desc-only.html

It defines synchronized media as:
"audio or video synchronized with another format for presenting information and/or with time-based interactive components, unless the media is a media alternative for text that is clearly labeled as such"

My confusion is around "audio or video synchronized with another format" -- what is "another format"? What would some examples of synchronized media be? Does this necessarily include something like a movie?

So does this mean that all videos (I mean, audio & video, like what you would see on youtube) would require described audio in order to meet this SC?
