13:03:10 <Zakim> I don't understand 'next itemzakim, next item', jasonjgw
13:05:01 <SteveNoble> jasonjgw: Have found tables in wiki page useful
13:05:27 <SteveNoble> https://en.wikipedia.org/wiki/Comparison_of_video_container_formats
13:06:07 <SteveNoble> jasonjgw: Different container formats can contain transcripts and subtitles in packages
13:06:50 <SteveNoble> janina: Differences between transcripts and captions which are not well defined in specs
13:08:42 <SteveNoble> janina: Metadata needs to define whether captions and transcripts are part of the package
13:10:41 <SteveNoble> jasonjgw: Need to review container formats more thoroughly.
13:11:08 <SteveNoble> present+ Raja
13:12:02 <SteveNoble> Raja: One element is the intellectual property considerations for some of these container technologies
13:13:54 <SteveNoble> janina: Example of various IP licensing of content which limits descriptions from one vendor to another
13:15:21 <SteveNoble> janina: Where and why something is blocked could be contained in the metadata
13:15:55 <SteveNoble> Raja: Distinction between auto captions and human captions
13:16:26 <SteveNoble> Raja: For example, YouTube includes autocaptions
13:17:00 <SteveNoble> Raja: We need to confirm
13:17:43 <SteveNoble> Janina: Can a YouTube user turn on autocaptions?
13:19:01 <SteveNoble> Raja: Not sure if these are always provided, but the platform makes it possible to provide autocaptions
13:19:45 <SteveNoble> janina: Agree that we need to research and document these capabilities
13:20:14 <SteveNoble> jasonjgw: We can add more to our wiki page as we do our research
13:20:48 <SteveNoble> jasonjgw: We need to keep investigating over the next week or so...bring back next week
13:21:57 <SteveNoble> janina: Should also address in upcoming iterations of the EPUB standard

13:22:02 <Zakim> agendum 1 -- Media synchronization use cases and user needs. -- taken up [from jasonjgw]
13:22:29 <jasonjgw> zakim, take up item 2
13:22:29 <Zakim> agendum 2 -- Task Force publications relevant to metaverse standardization, and related issues. -- taken up [from jasonjgw]
13:23:30 <SteveNoble> jasonjgw: Not much to update since last time other than an additional reference that was added
13:24:48 <SteveNoble> janina: Do we also want to reference the MAUR?
13:25:03 <SteveNoble> jasonjgw: Would lean toward including it
13:25:55 <SteveNoble> janina: Content Useable may be generally applicable
13:26:13 <SteveNoble> jasonjgw: Further thoughts?

13:26:13 <Zakim> agendum 1 -- Media synchronization use cases and user needs. -- taken up [from jasonjgw]
13:26:25 <jasonjgw> zakim, take up item 3
13:26:25 <Zakim> agendum 3 -- Miscellaneous updates and topics. -- taken up [from jasonjgw]
13:26:58 <SteveNoble> jasonjgw: Other items we need to address?
13:29:53 <SteveNoble> janina: Discussion around plans to register accessible metadata for human readable
13:30:18 <SteveNoble> jasonjgw: We could help with taxonomy at some point
13:31:45 <SteveNoble> jasonjgw: Concerning IP issues around alternate media versions, there is a recent book on this
13:32:36 <SteveNoble> janina: Example of the DCMA exemption for accessibility
13:33:25 <SteveNoble> jasonjgw: Will send out the link to the reference
13:34:11 <SteveNoble> janina: Legal history on Fair Use statute which cites accessibility many years ago
13:34:54 <SteveNoble> jasonjgw: A lot happening on machine learning
13:36:37 <SteveNoble> jasonjgw: Recent research on emergent learning of AI, based on the theory of mind
13:37:49 <SteveNoble> Raja: Have noticed that there is less common data and a high chance of AI making up facts on low-incidence populations
13:38:31 <SteveNoble> Raja: There is a high chance of error in tools like ChatGPT
13:39:06 <SteveNoble> janina: Jutta Treviranus is a good resource on this
13:39:36 <SteveNoble> janina: She did a good presentation on AXE-CON about this
13:41:01 <SteveNoble> jasonjgw: When AI starts making attributions about intentions for individuals, a lot can go wrong
13:42:13 <SteveNoble> jasonjgw: On the other hand, AI is doing a better job on image descriptions
13:43:28 <SteveNoble> Raja: AI as a captioning assistant, where a human corrects any inaccuracies as it is produced, is also a useful direction
13:43:30 <janina> Jutta's presentation at: https://www.deque.com/axe-con/sessions/preparing-accessibility-for-the-future-and-the-present/
13:44:28 <SteveNoble> jasonjgw: Anything else??
