16:16:24 <jcraig> no other agenda items
16:17:01 <jcraig> cyril: have others deployed AD in recent deployments
16:17:29 <jcraig> MPEG-H, coding audio descriptions, etc

16:19:14 <jcraig> q+
16:19:30 <nigel> jcraig: To Cyril's question, Apple has a number of different audio description features
16:19:40 <cyril> cyril has joined #tt
16:19:44 <rwarren2> rwarren2 has joined #tt
16:19:45 <nigel> .. as a streaming service provider with Apple TV+, I have no part of it but very proud of the work
16:20:00 <nigel> .. we do with AD and captions. Most of the Apple Original content has 9 AD languages and 40 caption track.
16:20:11 <nigel> .. On the product side, there are a number of features related to AD and captions that most people
16:20:25 <nigel> .. are not aware of. For example if you are blind and have a screen reader you can choose to have
16:20:38 <nigel> .. captions Brailled or spoken live (for translation).
16:20:46 <nigel> .. Experimented with something similar for audio descriptions.
16:20:55 <nigel> .. Eric Carlson and I demoed that 2 years ago in TPAC.
16:21:07 <gabrielbrito> gabrielbrito has joined #tt
16:21:09 <nigel> .. Take AD track type of the web <video> element, parsing it on the fly and either
16:21:23 <nigel> .. speaking it or Brailling it. Silent descriptions sent live to the Braille display.
16:21:32 <nigel> .. Someone who is deafblind could enjoy them widely.
16:21:41 <nigel> .. Not deployed widely, just a tech demo
16:21:50 <nigel> .. Love to get more interest in it, add the Braille support.
16:22:03 <nigel> .. That demo was a custom implementation of WebVTT in the video player
16:22:21 <jcraig> Adam_Page: Hilton deploying more AD to the webiste
16:22:26 <nigel> Adam_Page: Another data point. At Hilton, not a big video platform,
16:22:36 <jcraig> baking the audio track in
16:23:09 <nigel> jcraig: Second track is standard way to deploy AD now, with a tag saying it's AD, to support
16:23:12 <nigel> .. auto selection
16:23:18 <nigel> .. Technically just a standard audio track
16:23:22 <jcraig> user chooses the preferred track
16:23:38 <jcraig> most require extended.
16:24:28 <nigel> jcraig: One of the things was descriptions longer than the natural gap in the audio, e.g.
16:24:43 <nigel> .. extended descriptions, we demoed auto pause of video in the player when that happened.
16:24:49 <nigel> .. Have not seen a lot of deployments of that.
16:24:56 <cyril> RRSAgent, pointer
16:24:56 <RRSAgent> See https://www.w3.org/2024/09/26-tt-irc#T16-24-56
16:25:03 <nigel> .. I think WGBH has some demos of extended description
16:26:04 <jcraig> jcraig: demo in Vancouver was extended lecture paused to describe a chart
16:26:35 <jcraig> nigel: BBC deploys choice between pre-mixed audio trck with AD versus w/o
16:27:03 <jcraig> also deploying a dry AD track (not mixed with main audio) plus mix data
16:28:11 <jcraig> DVBT is widely deployed and supported in the UK
16:28:29 <jcraig> transport stream is specified in the UK's "d-book"
16:28:41 <jcraig> cyril: UK-specific technology?
16:28:49 <jcraig> nigel: yes, since 2006 or so
16:28:56 <rwarren2> "Widely available for a large amount of money" ;)
16:29:01 <jcraig> That's the broadcast standard
16:29:19 <jcraig> online we deploye separate video files like Hilton
16:30:04 <jcraig> lately starting to deploy Live descriptions... timing is an artform.. the describers research ahead of time
16:30:14 <jcraig> cyril: is the describer local or remote?
16:30:27 <jcraig> nigel: either... third-party service
16:30:35 <jcraig> Adam_Page: English only?
16:30:40 <jcraig> nigel: yes
16:31:01 <jcraig> ??: thinking of replicating the live AD use case into browsers as well?
16:31:21 <cyril> s/??/wschi/
16:31:31 <jcraig> nigel: 3-4 yrs ago, demoed TTML2 with live mix instructions in the browser
16:31:45 <jcraig> could be used for live broadcast, too
16:32:39 <jcraig> tech demo can mix two audio tracks using mix data (well) and/or less-well mixed with text-to-speech (generated speech synthesis)
16:33:37 <jcraig> could deploy as SADM, or we may deploy as a custom implementation in the BBC player
16:33:45 <wschi> s/SADM/sADM/
16:34:02 <jcraig> ??: NGA can include AD, and spatial position to separate

16:37:53 <jcraig> cyril: how widely deployed is AD around the world?
16:38:10 <jcraig> Are there countries with no AD? distribution?
16:38:33 <jcraig> nigel: BBC Audio describes over 20% of our programs.
16:38:55 <jcraig> other countries do some percentage
16:39:09 <jcraig> jcraig: smaller percentages
16:39:32 <jcraig> cyril: is AD deployed widely in Japan?
16:40:39 <jcraig> ??: audio subchannels are popular in Japan... for example, background data about baseball players during games.... Not as widely deployed for AD for the Blind
16:40:46 <jcraig> q+
16:41:32 <jcraig> nigel: most recent olympic games in Japan included additional data (NHK?) on the subchannel generating AD about the scores
16:41:53 <jcraig> ??: not sure of which subchannels are auto-generated or not?
16:42:14 <jcraig> nigel: one development in AD that has been gaining in use is synthesized voices
16:42:50 <jcraig> there is an advocacy group in UK that has been running user test experiments

16:44:25 <nigel> q?
16:44:30 <nigel> ack jcraig
16:44:41 <nigel> jcraig: Deployments in Japan: more common with streaming services.
16:44:53 <nigel> .. Japanese is one of the languages that Apple Original content localises to
16:45:17 <nigel> .. HBO is starting to ramp up as well, and starting to lead the way with signed / PiP / ASL movies,
16:45:43 <nigel> .. being deployed as separate video files because there isn't a way to compose the dry components
16:45:46 <nigel> .. and keep them in sync
16:46:00 <rwarren2> rwarren2 has joined #tt
16:46:27 <jcraig> nigel: on the tangent of sign interpretation, there is a new regulatory requirement in Spain
16:46:59 <jcraig> 3Cast (Catalonian broadcaster) recently demoed an HTTBV receiver?
16:47:27 <jcraig> Got the signing stream over IP and recompositing, implementation in WASM
16:47:43 <jcraig> s/recompositing/recomposited/
16:48:03 <nigel> s/3Cast/3cat/g
16:48:26 <jcraig> I think the resolution of the signed video was lower than the main broadcast video
16:48:27 <nigel> s/3/.. 3
16:48:32 <nigel> s/Got/.. Got
16:48:47 <nigel> s/I think/.. I think
16:49:06 <jcraig> jcraig: resolution does not need to be as high, but high framerate is critical with sign language... easy to lose context with dropped frames
16:49:14 <nigel> Topic: DAPT
16:49:51 <jcraig> nigel: this spec has originations back a few years
16:50:10 <jcraig> TTML could trigger audio playback, pitch, etc, audio mixing etc
16:50:45 <jcraig> but in general TTML is a TT format... I tried to do an AD variant, but had not as broad uptake
16:51:03 <jcraig> so DATP is AD plus mainstrean dubbing as use cases
16:51:21 <jcraig> and other uses
16:52:06 <jcraig> thinking of production workflows, video will be commissioned and produced... Loc and AD comes later as a second step
16:52:54 <jcraig> usually need a transcript.... for SDH subtitles or localized translation subtitles
16:53:38 <jcraig> cyril said these processes are sometimes too removed, and the dubbing plus translation can be mismatched
16:53:46 <jcraig> q+ to mention FCC DAC report
16:54:09 <jcraig> trying to convince players to move the transcription process earlier in the chain
16:54:48 <jcraig> a lot of the service provider use proprietary tools
16:54:50 <nigel> q?
16:54:52 <nigel> ack jcraig
16:54:52 <Zakim> jcraig, you wanted to mention FCC DAC report
16:55:15 <nigel> jcraig: I can share afterwards - I'm Apple's rep to the FCC disability advisory committee
16:55:26 <nigel> .. and worked on a report for the commission with other people, which is public, I'll share the link later,
16:55:43 <nigel> .. which is effectively guidelines and recommendations for broadcasters and streamers for how
16:55:56 <nigel> .. to do exactly this, and which specific resources should be deployed widely with the original video.
16:56:16 <nigel> .. A lot of time the contracts for production do not include the accessible alternatives, for subtitles,
16:56:21 <nigel> .. descriptions, translations etc.
16:56:38 <nigel> .. So then when the content goes to cable providers etc., the recommendations talk about this
16:56:50 <nigel> .. particular item, the audio description transcript and ideally timing, as well as the dialogue,
16:57:05 <nigel> .. should as much as possible be considered and distributed by the original distributor, to avoid this mismatch.
16:57:23 <nigel> .. Which avoids rework and mismatch when there's already prior work that's been done.
16:57:35 <nigel> .. Redub with different transcripts etc cause those problems.
16:57:54 <jcraig> nigel: Chris intro?

16:58:37 <cpn> cpn has joined #tt
16:58:58 <jcraig> nigel: broadly speaking, DAPT useful as a production tool
16:59:13 <jcraig> for Timeed Text, audio, etc
16:59:45 <ray-schwartz9> Need to head to another meeting. Thanks for letting me sit in!
17:00:05 <jcraig> moslty upstream of something that would go to the client devices, but DAPT could go directly to the player, for braille or TTS, local audio mix, etc.
17:00:21 <jcraig> including pans, levels, etc
17:00:31 <jcraig> nigel: intro?
17:00:42 <youenn> youenn has joined #tt
17:00:51 <jcraig> youenn: Youenn Fablet, Apple
17:01:29 <jcraig> nigel: doc includes examples to help people understand the use cases
17:02:10 <jcraig> tracking for translation, the current language and original lang ("pivot languages?")
17:02:39 <jcraig> ex: norwegian to hebrew.... probably passed through English as a pivot language
17:03:49 <jcraig> so by tracking through this, you may have a better idea of how to avoid or correct mistranslations
17:04:46 <jcraig> metadata describes characters (the type played by actors) and other info
17:04:58 <jcraig> s/played/portrayed/
17:06:04 <jcraig> metadata could differentiate visual descrioption vs transliteration of text rendered visually on screen... (time or location chyrons, as an example)
17:06:52 <jcraig> scanning through the document... showing timed text example of AD... along with mixing data
17:07:22 <jcraig> also can include prerecorded audio
17:07:48 <jcraig> showing Gain attribute data
17:08:42 <jcraig> result is that is ducks the main program audio while AD mix is played, and re-raises the gain after the "ducking"
17:08:59 <jcraig> q+
17:09:07 <jcraig> q+ to ask about ducking prefs
17:09:11 <jcraig> ack me
17:09:11 <Zakim> jcraig, you wanted to ask about ducking prefs
17:09:21 <wschi> q+
17:09:53 <nigel> jcraig: Screen readers often have a setting for ducking audio, not used when there's pre-mixed audio
17:10:21 <nigel> .. Is there more data here than just the gain, like a context, like "this is a ducking transition",
17:10:32 <nigel> .. because that would potentially allow the user preference for ducking.
17:10:38 <nigel> qq+ to answer that
17:10:52 <nigel> .. Is there semantic information about why the transitions are happening?
17:11:03 <nigel> cyril: I don't think we thought about that use case, semantic signalling,
17:11:19 <nigel> .. but I see that it could easily be added - TTML is easily extended, either in the spec or with
17:11:24 <nigel> .. proprietary information.
17:11:26 <Dana> Dana has joined #tt
17:11:39 <nigel> jcraig: Talking about sub-channel audio for a baseball game earlier, some people might want
17:11:49 <nigel> .. to hear that in the same room as others who do not.
17:12:00 <nigel> .. That mixed data could be deployed to a different channel or speaker.
17:12:08 <nigel> .. That type of semantic metadata could also apply.
17:12:25 <nigel> rwarren2: A friend who has gone blind late in his life: enjoys baseball,
17:12:33 <cyril> cyril has joined #tt
17:12:34 <nigel> .. but now it's not on the radio, there's a change in the announcement style
17:12:47 <nigel> .. It's frustrating because they no longer know what the action is, because the assumption
17:12:54 <nigel> .. is that you can see what's happening.
17:13:11 <nigel> jcraig: Anecdotally, I have a lot of blind friends into baseball, who would like that.
17:14:08 <jcraig> s/who would like that./who would like that. My assumption is because the position don't move, and you can build a mental picture based on action that is described well, like it used to be on radio./
17:14:54 <jcraig> nigel: Irish commission researched about appropriate ducking levels based on how loud the program audio is, how much to duck, and how loud the AD should be.
17:15:11 <jcraig> so that bg sound does not drown out the description
17:15:50 <jcraig> so "one size" does not "fit all" when it comes to audio ducking
17:16:56 <nigel> q?
17:16:58 <nigel> ack me
17:16:58 <Zakim> nigel, you wanted to react to jcraig to answer that
17:17:05 <nigel> ack wschi
17:17:12 <jcraig> anecdotal data point, visited VRT in ?? would hand tweaking gain to allow un-ducking relevant noise ("door opening") during  AD dialog, to improve understandability
17:17:36 <jcraig> ??: ho do you stream the XML?
17:17:49 <jcraig> nigel: could be one big file...
