Item Number: Guideline 1.2: Provide synchronized alternatives for multimedia
Part of Item: 
Comment Type: technical
Comment (Including rationale for any proposed change):
The definition of \"multimedia\" correctly provides that multimedia content must

be audio or video, synchronized with another format or involving time-based

interaction. Audio-only and video-only content are not multimedia.

Under sc 1.1.1, live audio-only and video-only content is required to be

identified with a text equivalent. However, nowhere in guideline 1.1 or

guideline 1.2 is it required to be accompanied by a text transcript, at any

level of conformance; and pre-recorded audio-only and video-only content (not

being multimedia) appear to escape coverage altogether.

Thus, a radio station for example that provides transcripts of some of its

content (and such transcripts do exist) isn\'t achieving a superior level of

accessibility under WCAG than a radio station which does not provide such


Proposed Change:
Under guideline 1.1 or guideline 1.2, at different conformance levels if

necessary, provide for transcripts of both live and pre-recorded audio-only

and video-only content.
