<Clarke> User Clarke Stevens shared the file "DVS Dual Labeling 6-16-2014.pptx" with you. It is available for download here: https://owncloud.cablelabs.com/public.php?service=files&t=c93b3b23f897e70d5398c3c8e18be9bd
cs: Has three slides in the
ppt
... 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
... Taken this proposal to CEA Media
... Accepted, also Sony has tested
... also gone to NAB, tentavie agreement there
... Bob Lund and Silvia Pfeiffer believe already accounted for
in our HTML text track
ms: So traditional SAP marker is being used as a fallback
cs: Supports older equipment which doesn't know AC3
<Clarke> "Elephant's Dream_DVS_DD_v2.mpg" is available here: https://owncloud.cablelabs.com/public.php?service=files&t=b1acaa4dc1f4b8e311ef71eada5fb547
cs: This is a test stream that
illustrates this
... Motiviation is industry accepted solution before any
regs
... Can be updated, when new equipment becomes ubiquitous
JS: this sounds good to me. I was wondering what the capacity in digital transport for this alternative content is. Is there any possibility to send multiple language audio tracks
js: Asks about ability to support more than one additional secondary track
cs: designed to support the web
case where numerous tracks are supportable, and all could be
correctly labeled
... 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
ms: Noting TF wish list for html.next
<MarkS> 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.
MS: I think we would need to identify the video first, then begin gathering accessible tracks
JS: I can reach out to Suzanne Taylor. would like a review of my email, proposal to her.
...RE: transcript, this can be done in 5.1. timeline. there has been work done on this already.
...we have authority under plan 2014 to do this.
...no agreement on which approach to take
...possibly publish both
...AAPL approach was to put a link to the video nearby to the transcript
...GOOG approach was more elaborate to the point where it started to be confused with captions
MS: sounds like we need to find out where we left off with those
JS: I need to do that. the interest was mainstream.
MS: can we use aria to achieve this?
JS: for apples approach, yes
...would be a good idea
