Meeting minutes

<scott_h> following on IRC< hoping to join call shortly

Media synchronization use cases and user needs.

jasonjgw: Just a placeholder for the wiki at the moment

jasonjgw: Any general comments on expanding media synchronization to new forms such as transcript synchronization

janina: Will look at old meeting notes from a meeting where this was discussed several years ago

jasonjgw: Currently, transcripts are provided as separate files

jasonjgw: But not sure how well video APIs can provide navigation to various points in the video

janina: Tools exist to fix post caption files for better synchronization, so that is a model

janina: In musical works, synchronization of text may be possible with MusicXML

jasonjgw: Whether we want textual content to go into media files so that it is embedded and does not have to be a separate file

jasonjgw: Level of synchronization (word or sentence level) would be something to look at

Raja: In transcripts, timestamps are needed. There is more support now in tools that provide synchronization.

Raja: AI is getting better at figuring this out.

Raja: But most synchronization is at the sentence level, not the word level.

Raja: There are differences in what is supported in live streaming vs. pre-recorded.

janina: What differeneces do you see in transcripts? We were hoping that transcripts would include on-screen information and not just spoken dialogue?

Raja: There has been a request for this sort of information, but it seems to mostly come over in text audio descriptions and not in captions.

Raja: There is a best practice for both captions and audio descriptions, and those can be considered.

Janina: We were thinking that for the deaf-blind population, the synchronization with the video was not as important.

Raja: More video players are starting to include the ability to search for words.

jasonjgw: Finding where certain words appear and moving to that point would be useful to some people.

jasonjgw: Seems like we need to do some more investigating on what is currently possible and what so far doesn't exist.

Lionel: In YouTube, timed transcript playing is already available

Lionel: In streaming contexts, the streaming rate can vary depending upon how much video quality is required.

Raja: There are some opensource players that provide some of these capabilities, but am unsure of this is any of the specifications.

janina: The standards do not seem to currently include these capabilities, be we need more exploration

Raja: Happy to help out on tracking these details down

Raja: You are referring to the link you sent on teh mailing list?

Miscelaneous updates and topics.

jasonjgw: Yes...it is just a placeholder right now. We can continue this discussion next week

Ax-Con Presentation

<janina> Jutta Treviranus presentation

janina: Suggest the presentation is something we consider for mining on possible topics

jasonjgw: She also had a good presentation during the Future of Interface conference

jasonjgw: Also some good presentations on other topics worth our focus


jasonjgw: Still negotiating on a meeting time


janina: Waiting on a response from COGA

janina: Not sure as to what format these comments will come in

janina: May have an update next week after COGA meets

jasonjgw: Will still have to peel out comments into GitHub issues

scott_h: Thanks for continuing to work through this!


janina: APA will be discussing this.

janina: Issues in WoT GitHub repository have been filed...looking at middleware, or "provisioning" as they are calling it

jasonjgw: Important for us to keep following this

jasonjgw: Other comments??

jasonjgw: Our first agendum will come back next week
