Re: Synchronised media ambiguity again

It seems like this is the heart of the discussion - must a video with ambient sound be considered synchronized video with synchronized requirements. This means that captions would be required even if the captions were to only show music symbols or perhaps a short description of the type of music playing. If the video contained images that communicate feeling then audio description would be needed rather than a transcript for Level AA.

Regarding WCAG SC 1.2.1 it seems to say "video only" and "audio only" content. There is no clear situation for combined video and audio content where one aspect is decorative. And what if there were - what is the factor in determining if an image or sound is meaningful or decorative? Music sets mood and images convey feeling.
