Here are some examples of WebVTT use for non-captions, in case you are interested: For audio descriptions: https://chrome.google.com/webstore/detail/html5-audio-description-v/jafenodgdcelmajjnbcchlfjomlkaifp?utm_source=chrome-ntp-icon or https://chrome.google.com/webstore/detail/html5-audio-description-v/jafenodgdcelmajjnbcchlfjomlkaifp?utm_source=chrome-ntp-icon or For chapters, thumbnails and scripting: http://demo.longtailvideo.com/track/ or http://demo.longtailvideo.com/track_demos/chapters.html It's probably possible to do these with TTML, too, at least from what Glenn seems to think. >> They are likely orthogonal in some features, which cannot be mapped >> to each other, but can map for others. > > Similarly, do you have concrete examples? The latter will be needed to > make technical progress in my mind. I don't, because it takes a bit of investigation. But I see that Glenn has the same hunch. Regards, Silvia.
