21:37:34 <Zakim> agendum 17. "Clean Audio: Adjusting our Kinds and our docs" taken up [from JF]
21:38:02 <janina> zakim, who's here?
21:38:02 <Zakim> On the phone I see JF, silvia (muted), Janina, Bob_Lund
21:38:04 <Zakim> On IRC I see Bob_Lund, janina, silvia, RRSAgent, JF, MikeSmith, Zakim, [tm], trackbot
21:38:17 <janina> regrets: Judy_Brewer
21:40:14 <JF> JS: this is what Sean discovered about Clear audio - it's clean Audio
21:40:16 <Zakim> +Eric
21:40:44 <JF> once we made this discovery, we were able to find documentation
21:40:58 <JF> suggests thta we change our docs as well as list of @kind
21:41:50 <JF> initial premise is in a 5:1 setting, the center channel is dedicated to dialog, thus if we can reduce/remove the other channels it will allow for better comprehension
21:42:35 <JF> seems that this is UK based, although picked up by ETSI
21:43:42 <JF> see: www.etsi.org
21:44:11 <JF> JS: seems that Silvia has already corrected the wiki
21:44:29 <JF> we need to discuss changing our @kind for this
21:44:33 <JF> is there any dissention?
21:44:42 <silvia> zakim, unmute me
21:44:42 <Zakim> silvia should no longer be muted
21:45:10 <JF> JS: less clear is the implication supporting this understanding of clean audio
21:45:19 <JF> with respect to control and our user-requirements
21:45:31 <JF> s/control/controls
21:46:04 <JF> SP: looked at clean audio as a track-level problem
21:46:32 <JF> we would have a track that hadd all audio content, and a second track with only the speech audio
21:47:11 <JF> however when analized this there are actually 2 ways of doing and delivering this
21:47:24 <JF> one is a 3 channel - left, right and speech
21:47:48 <JF> that remains one audio track (interleaved) 
21:48:35 <JF> 5:1 audio is similar as well
21:49:02 <JF> but now they are replacing the center channel with just speech, which allows people to increase the vlume of center to replicate clean audio
21:49:58 <JF> SP: question is how to get control of the center track
21:50:24 <JF> EC: additional problem and serious problem, is that most container formats cannot 3 or 5 channel audio
21:50:39 <JF> it can only be stereo or mono
21:51:00 <JF> for example mpeg 1 and mpeg3 
21:51:19 <JF> very little today is encoded in anything but stereo
21:51:52 <JF> SP: the 3 relevant formats can (I believe) support multi-track formats, but therer are likely few files like that in the wild
21:52:17 <JF> and it pushes the problem into a larger area, and one that we cannot handle with JavaScript
21:52:38 <JF> prefer we create a new @kind called 'speech" which would be an individual speech track
21:53:09 <JF> EC: think this is the right way forward as well
21:57:58 <JF> SP: the API we have shold handle this. the ETSI spec is just a spec, don't believe there is any implementation in the wild to date
21:58:38 <JF> (Eric and Janina are provisional agreement, bob doesn't have an informed opin)
21:59:19 <JF> SP: suggest we put this on the list, see if there is any opposition to @kind of speech, and if no opposition then change the bugs to reflect this change
21:59:35 <JF> JS: perhaps invite somebody with experience with Clean audio to speak with us
21:59:49 <JF> SP: would LOVE to have somebody with experience to consult with us
22:00:11 <JF> if janina can find somebody that would be highly appreciated
22:00:57 <JF> zakim, next item
22:00:57 <Zakim> agendum 18. "Paused Media: Continuing Discussion" taken up [from JF]
22:01:27 <JF> SP: does it make sense to start a new thread?
22:01:48 <JF> (Question was about Clean Audio thread on the list)
22:02:00 <JF> JS: Paused media, where are we?
22:02:16 <JF> there has been a lot of discussion on list, including some new issues bob has introduced
22:02:23 <JF> not clear where to start
22:02:35 <JF> SP: an interesting week on that topic
22:02:43 <JF> we have trickled out a lot of thoughts
22:03:00 <JF> in my mind what we have started doing and where we are is very iunclear
22:03:17 <JF> started a list a few days ago, and should be updated on the dimensions we are trying to grapple with
22:03:29 <JF> one dimension is whether we have a graphical or text only browser
22:03:43 <JF> may be a side issue, but spills into this discussion as a use-case
22:03:58 <JF> the other is the video player design, how do we expose that textually?
22:04:05 <JF> to the accessibility API?
22:04:14 <JF> then what to do with the representative frame?
22:04:25 <JF> relates back to the missing autoplay attribute
22:04:54 <JF> another use-case is how we represent the video content short description, a longer description and full transcript
22:05:25 <JF> and then the still image need for short and long descriptions
22:05:55 <JF> SP: trying to keep the use-case clear and separate without looking at 'solutions' at this time
22:07:08 <janina> scribenic: janina
22:07:37 <janina> jf: If I'm understanding Silvia correctly, then I agree with this.
22:07:51 <janina> jf: Believe it comprehends the distinctions I've been trying to represent all along.
22:08:12 <janina> jf: If yes, think we've captured the requirements.
22:08:19 <silvia> summary is also at http://lists.w3.org/Archives/Public/public-html-a11y/2011May/0367.html
22:08:21 <janina> ec: Well, I may disagree
22:08:41 <janina> jf: Tried carefully not to go to solutions but to state the needs, the user requirements
22:09:01 <janina> jf: Don't know how to answer "don't agree" when it's about user reqs ...
22:09:24 <janina> sp: Eric, what do you disagree with
22:09:37 <janina> ec: separate representation of the first frame
22:10:01 <janina> sp: that's the next step, i haven't gone there yet
22:11:43 <janina> sp: Next step would be to group things together, and create cnadidate ml
22:12:49 <janina> sp: trying to keep emotion out of this and find the best way to ml, based on good req understanding
22:13:58 <janina> jf: looking at the list in email -- graphical browser -- but think textual description for still images is missing
22:15:21 <janina> jf: if no visual text, we're not obligated to supply text to AT
22:15:34 <janina> jf: But, if graphic, we neet the graphic alternatives, short and long
22:16:49 <janina> jf: so what happens when there's no poster summary, but a poster?
22:17:44 <janina> jf: also agree that whether a first frame or external image is immaterial
22:18:36 <janina> ec: thought we were proposing descriptions ov video to supply to at for those who couldn't see the image
22:18:53 <janina> jf: if there's imagery on screen, it requires both a short and long description mechanism
22:20:17 <janina> jf: image and imagery are substantively the same for this purpose
22:21:00 <janina> janina: suggesting the short and long descriptions are fully in sync with longstanding wcag guidance
22:22:03 <janina> sp: do we need separate descriptions for video and the paused representation
22:22:11 <janina> jf: yes, because they describe different things
22:22:22 <janina> sp: why not one follow the other?
22:23:21 <janina> jf: we have the video element, it's the player chrome. it needs a11y name, etc., and we put things in this player including the video/audio when we press play
22:23:48 <janina> jf: the other thing inside that container, when the video isn't playing is a still image which needs description
22:24:07 <janina> sp: but if it was presented in the summary, does it need to be repeated?
22:24:20 <janina> jf: depends on how presented to the user
22:24:33 <janina> jf: what happens when i pause at 4 secs? poster, no.
22:25:05 <janina> jp: not that we need to describe every frame, but it may be useful to describe certain internal video frames
22:26:27 <janina> sp: so i want to go back to the use case of chapters, subchapters, etc
22:26:41 <janina> jf: except, this may be a useful way to handle that
22:28:13 <janina> sp: we remove an entire level of complexity if we can sequentially satisfy this
22:28:24 <janina> jf: want to check with several people for feedback
22:28:50 <janina> jf: question of what happens when the poster frame doesn't actually say anything about the video
22:29:12 <janina> sp: You can still add that text.
22:30:02 <janina> ec: by definition whatever is in the first frame is related to the video
22:30:44 <janina> ec: if we decide we need a second representation of that frame, we also need to decide when at presents that data
22:31:10 <janina> ec: e.g., if autoplay is on, you never get there
22:31:37 <janina> sp: which why i thought it should be regarded as background to the video
22:32:10 <janina> jf: but it's not a background image, background image has certain meanings, and this isn't it
22:32:39 <janina> sp: yes, same problem with button
22:33:08 <janina> jf: probably not likely though
22:34:02 <Zakim> +Eric.a
22:34:03 <Zakim> -Eric
22:34:35 <janina> sp: with css?
22:34:50 <janina> janina: pf is looking at it, rather behind on our css coordination
22:36:32 <janina> jf: the issue with autoplay is one key reason why i was pushing child element
22:36:43 <janina> sp: but it also doesn't solve the problem
22:37:01 <janina> jf: but it's a child of video in the dom, whether or not it takes an external image
22:37:37 <janina> sp: not technically possible
22:37:52 <janina> jf: not so sure, it can take on properties, e.g. description
22:39:27 <janina> sp: what to do in the fallback case? when it doesn't understand video element
22:39:47 <janina> sp: a broken image in the browser
22:40:08 <janina> jf: it's not an image element, it's a new element, so older browser that don't understand video won't understand this one either
22:40:33 <janina> ec: that frame is only displayed until video is started, and never again
22:41:46 <janina> jf: users wfor whom this matters will all turn autoplay off
22:42:22 <janina> janina: absolutely
22:42:44 <janina> jf: so users for whom this matters will see all the dexcriptions before starting the video
22:43:37 <janina> janina: what about when the video is stopped and the page reloaded
22:43:45 <janina> ec: it's reset
22:43:51 <janina> jf: is that wrong?
22:44:15 <Zakim> -Eric.a
22:45:13 <janina> ec: just don't understand why you need to separately describe something that's only there as a standin until the video starts
22:46:50 <janina> sp: we need to solve the problem that covers both circumstances, first frame, chosen frame, or external image
22:48:29 <janina> sp: why not a div or p inside the frame
22:48:35 <janina> jf: no, because no semantec meaning
22:49:13 <janina> jf: are you saying the description of the static image is the same as the description of the video?
22:49:32 <janina> sp: i think it's one thing that goes into the default fallback
22:50:18 <Zakim> -Bob_Lund

22:56:33 <silvia> <video src="file.mp4" poster="file.png" aria-describedby="posteralt videosummary">
22:56:58 <janina> jf: remember short description is read auto; but the longer description is only invoked by the user
22:57:07 <silvia> <p id="videosummary">A Clockwork Orange Trailer</p>
22:58:01 <janina> sp: we'll always need to go to a link for longder; which is where transcription came in
22:58:13 <silvia> <p id="posteralt">A clockwork orange poster</p>
22:58:15 <silvia> </video>
22:58:31 <janina> jf: but the longer description is not part of the transcript
22:58:44 <janina> jf: also the id attrib doesn't map to a11y apis
22:59:23 <janina> sp: can we focus just on short alts for now?
23:00:30 <janina> jf: i'm already seeing you have children of video, which is correct, imho
23:00:59 <janina> sp: nice that video gives a way to hide text on page without hacks
23:02:20 <silvia> <video src="file.mp4" poster="file.png" aria-describedby="posteralt videosummary">

23:04:26 <silvia> </video>
23:05:26 <silvia> actually, here's an even better one:

23:05:51 <silvia> p id="videosummary">A Clockwork Orange Trailer (<a href="transcript.html">Transcript</a>)</p>

23:06:18 <silvia> </video>
23:07:30 <janina> sp: will allow a right click on transcript
23:08:42 <janina> jf: this feels right
23:08:58 <janina> jf: want to review aria roles,to make sure we can get that in
23:15:18 <janina> jf: think this might work, will check around with several people
