Wants to discuss labeling for video descript in traditional broadcast ... Don't think there's any impact on this group, but worth checking ... Also informs us what's happening js: asks to clarify that cs means traditional video descript cs: when additional audio track is sent, tend to use SAP ... or second audio track ... traditionally labeled as "spanish" ... In CA it's labeled as "middle English" ... Turner labels it "Portugese" ... using ac3 lang descriptor ... also an audio descriptor ... bsmod available for labeling ... also provides lang identifier ... uses iso639 ... if using this descriptor, labeling is accurate ... people should be using it, the ac3 audio descriptor ... Cable has proposed "dual labeling" labeling both as "spanish" and also (correctly) in ac3 audio descriptor ... assumption is the older sets will not parse ac3 ... newer equipment will use ac3 ... testing to date proves this ...

I have a white paper that shows this in preparation ... includes marker for "hearing impaired audio," what we are calling "clean audio." sm: notes that Minnesota public broadcasters chose to use their bandwidth for multiple video channels ms: asks about epg, and what data is available to show JS: parallel secondary video track, someone might actually create a second track that a deaf person would use instead of captions because it would be signed, PiP. ...i believe a set of language indicators that made a distinction between the different intl sign-languages <Zakim> just, you wanted to clarify about multi-tracks in minnesota Full Transcript ms: Noting TF wish list for html.next <MarkS> [15]https://www.w3.org/WAI/PF/HTML/wiki/Full_Transcript [15] https://www.w3.org/WAI/PF/HTML/wiki/Full_Transcript JS: I also want us to discuss putting together a working demo that showcases all of the features and permutations of accessible video ...i think we had various reps industry to help us put this together.
