14:06:18 <kaz> cpn: TPAC is coming up
14:06:26 <kaz> i/TPAC/topic: TPAC/
14:06:40 <kaz> ... (shows the basic structure)
14:07:20 <kaz> ... the question is whether we'd like to meet or not
14:07:31 <kaz> ... a few suggestions here
14:07:51 <kaz> ... 18-22 Oct: breakouts
14:08:02 <kaz> ... 25-29 Oct: Group meeting
14:08:42 <kaz> ... currently planned: WebRTC, Media, WebTransport, WebRTC
14:09:04 <tidoust> -> https://github.com/w3c/media-and-entertainment/issues/25#issuecomment-866684452 Possible topics for WebTransport
14:09:08 <kaz> ... do we want to have a joint meeting with WebTransport, etc.?
14:09:33 <kaz> jake: updates on Web Transport?
14:09:43 <kaz> fd: put info above
14:09:48 <cpn> https://github.com/w3c/webtransport/blob/main/explainer.md WebTransport explainer
14:09:54 <kaz> ... there is an ssue (Issue 25)
14:09:59 <kaz> s/ssue/issue/
14:10:04 <jholland> webtransport use cases: https://github.com/w3c/webtransport/blob/main/use-cases.md
14:10:20 <kaz> cpn: Multicast CG may be considering joint discussion
14:10:37 <kaz> jh: ok
14:10:46 <kaz> ... use cases document above
14:11:07 <kaz> ... do you have other use cases in mind?
14:11:35 <kaz> fd: basically, low-latency and live streaming
14:12:05 <kaz> jh: do agree but in terms of media...
14:12:11 <kaz> cpn: my question was...
14:12:35 <kaz> ... whether we'd use Web Transport for low-latency distribution or not
14:12:59 <kaz> ... live streaming scale for large number of viewers
14:13:05 <kaz> zakim, who is on the call?
14:13:07 <Zakim> Present: Chris_Needham, Andreas_Tai, Takio_Yamaoka, Tatsuya_Igarashi, Kazuyuki_Ashimura, Francois_Daoust, Nigel_Megitt, Rob_Smith, Jake_Holland
14:13:15 <kaz> ... not really my own expertise
14:13:29 <kaz> iga: CDN support for low-latency streaming
14:13:45 <kaz> ... kind of implementation issue on that
14:14:10 <kaz> present+ Gry_Katsevman
14:14:15 <kaz> present+ Kazuhiro_Hoya
14:14:27 <kaz> ... not aware of other requirements myself
14:14:48 <kaz> cpn: don't want to push multicast topic at the moment
14:15:27 <kaz> ... but joint discussion on WG's requirements, etc., would make sense
14:15:51 <kaz> iga: live streaming for low-latency is a good use case for us
14:16:16 <kaz> jh: would ask if there is any implementation
14:16:39 <kaz> ... interesting to know
14:17:00 <kaz> ... Web Transport is already out?
14:17:05 <kaz> cpn: not sure about the status
14:17:22 <kaz> ... maybe in Chrome but as experimental feature
14:17:31 <cpn> https://web.dev/webtransport/
14:17:33 <kaz> ... like web-dev
14:17:45 <kaz> ... status update table there
14:17:57 <kaz> ... happy to organize a joint meeting
14:18:14 <kaz> ... need to decide the agenda, though
14:18:24 <kaz> ... who to present what...
14:18:39 <kaz> ... anybody who implemented may talk
14:18:50 <kaz> jh: if there is anybody, would be interested
14:19:17 <kaz> cpn: Will Law is the co-Chair
14:19:20 <kaz> jh: can ask him
14:19:23 <kaz> ... or Ali
14:19:28 <kaz> cpn: great
14:19:46 <kaz> iga: we also can ask the Web Transport WG if they think about CDN support
14:19:49 <kaz> cpn: yes
14:20:13 <kaz> jh: it's already listed as a use case
14:20:21 <kaz> iga: usage of CDN?
14:20:33 <kaz> jh: anybody who provide the service
14:21:11 <kaz> iga: what about limelight?
14:21:38 <kaz> ... they already provide CDN for low-latency streaming on WebRTC
14:21:51 <kaz> ... similar approach to be applied
14:22:00 <kaz> jh: yeah
14:22:16 <kaz> ... don't know about the pros and cons, though
14:22:39 <kaz> cpn: let's organize a joint meeting with the Web Transport WG
14:22:43 <kaz> jh: ok
14:23:01 <kaz> ... interested in finding an implementation
14:23:13 <kaz> cpn: in the early discussion we had
14:23:33 <kaz> ... people were thinking about sending CMAF message
14:23:50 <kaz> ... can we make a dedicated secure protocol?
14:24:24 <kaz> iga: the other benefit of WebRTC is application's having low-latency control
14:24:31 <kaz> q?
14:24:31 <cpn> q?
14:24:52 <kaz> cpn: next
14:24:55 <kaz> ... MiniApps
14:25:06 <kaz> ... Chris Lorenzo is interested
14:25:12 <kaz> s/Apps/Apps for TV devices/
14:25:20 <kaz> ... maybe concerns about Web technologies
14:25:37 <kaz> ... in terms of efficiency of UIs for low-power devices
14:25:47 <kaz> ...he has been looking at MiniApps approach
14:25:55 <kaz> ... could be interesting to look into it
14:26:31 <kaz> ... and gauge interest from other media companies
14:26:39 <kaz> ... doesn't have to wait until TPAC
14:26:52 <kaz> ... can have a joint meeting with them earlier
14:27:17 <kaz> ... would be interesting to see if there is general interest
14:27:31 <kaz> ... then
14:27:43 <kaz> ... finally new areas?
14:27:55 <kaz> ... are we looking at the right things?
14:28:02 <kaz> q+
14:28:15 <kaz> ... and kind of related topic
14:28:25 <kaz> ... how to increase participation?
14:28:42 <kaz> ... covering right topics or not?
14:28:48 <kazho> kazho has joined #me
14:29:01 <kaz> ... could organize something about that
14:29:14 <kaz> ... post-TPAC planning
14:30:20 <cpn> kaz: Could be several levels to joint meetings: invite other groups to our meetings, or MEIG members visiting other groups and reporting back
14:31:11 <cpn> ... Discussion for expected joint meetings so far, inviting people into MEIG meeting. I'd like to suggest some MEIG members visit the WoT meeting to discuss TV devices and media streaming integration in the IoT context
14:31:35 <cpn> ... I organised a W3C workshop on smart cities. I'm generating a charter for a Smart Cities IG based on the results
14:32:15 <kaz> i/Could be/scribenick: cpn/
14:32:16 <cpn> ... May not be ready by TPAC, but could have a breakout session. Thinking about media streaming or content in general for smart cities could be another topic for TPAC
14:32:23 <kaz> scribenick: kaz
14:32:47 <kaz> cpn: yeah
14:33:24 <RobSmith> q+
14:33:35 <kaz> ... could be interesting though the detail is not clear yet
14:33:42 <kaz> ack k
14:34:38 <kaz> jh: possible use case on vide streaming?
14:34:57 <kaz> ... e.g. IoT devices (like video cams)?
14:35:07 <kaz> cpn: IoT aspects and smart cities aspects
14:35:32 <kaz> ... how to work together interoperably?
14:35:54 <kaz> ... media context within smart home environment, etc.
14:36:20 <kaz> kaz: and data governance in general
14:36:35 <kaz> rs: something I've been thinking about smart cities
14:36:45 <kaz> ... moving object data from video
14:36:57 <kaz> ... e.g., school busses to be tracked
14:37:11 <kaz> ... based on the video image captured by a webcam
14:37:26 <kaz> ... take a video frame to identify the target
14:37:38 <kaz> ... calculate the location from that
14:37:46 <kaz> ... metadata to handle that
14:38:00 <kaz> ... CCTV and also autonomous cars
14:38:16 <kaz> ... hoping some breakout sessions during TPAC
14:38:38 <kaz> cpn: interested in combining multiple data like that
14:38:51 <kaz> rs: combining multiple cameras as well
14:39:08 <kaz> ... can be identified from one specific vehicle
14:39:20 <kaz> ... to track the specific vehicle
14:39:43 <kaz> kaz: kind of scary :)
14:39:45 <kaz> rs: yeah
14:39:50 <kaz> ack r
14:40:00 <kaz> cpn: image processing and ML
14:40:15 <kaz> ... if you're organizing something, that would be good
14:40:45 <kaz> ... so if there is any possible discussion on smart cities, we can join it
14:40:49 <kaz> kaz: yes, very welcome
14:40:54 <jholland> +q
14:40:58 <kaz> cpn: rather than organizing something ourselves
14:41:01 <kaz> kaz: right
14:41:12 <kaz> jh: attaching metadata to video?
14:41:38 <jholland> -q
14:41:38 <kaz> rs: I'm working on WebVMT
14:41:59 <kaz> ... location side of geospatial data
14:42:21 <kaz> ... moving features work by OGC
14:42:43 <kaz> ... e.g., template at some location
14:42:49 <kaz> s/template/temperature/
14:43:45 <kaz> ... putting some resource on IRC
14:43:58 <kaz> cpn: we've got a separate activity about that
14:44:08 <RobSmith> OGC Testbed-17 MF: https://portal.ogc.org/files/?artifact_id=95726#MovingFeatures
14:44:43 <kaz> cpn: we should have discussion with TTWG as well

14:57:22 <kaz> topic: Open issue review
14:57:31 <kaz> cpn: GitHub issues
14:57:38 <kaz> ... a number of open topics
14:57:53 <kaz> ... good to decide whether we'd like to keetp them or not
14:58:11 <kaz> ... noticing Andreas is on the call
14:58:25 <kaz> ... question about environment
14:58:38 <kaz> ... makes me wonder if there is any progress
14:58:47 <kaz> ... any updates on the issues?
14:58:52 <kaz> at: there is another CG
14:59:01 <kaz> ... working on issues about captioning
14:59:15 <kaz> ... accessibility experts there
14:59:36 <kaz> ... maybe we could the issue on our side
14:59:44 <kaz> cpn: we could invite the CG guys
15:00:07 <kaz> kaz: which CG, btw?
15:00:10 <tidoust> s/we could the issue/we could close the issue/
15:00:19 <kaz> cpn: immersive captions, I thought
15:00:38 <tidoust> -> https://www.w3.org/community/immersive-captions/ Immersive Captions CG
15:01:09 <kaz> at: my impression is there is some discussion held in parallel there
15:01:19 <kaz> cpn: yeah
15:01:30 <kaz> ... cross-group coordination is important here
15:01:55 <tidoust> (CG meets regularly, see internal mailing-list archives: https://lists.w3.org/Archives/Member/internal-immersive-captions/2021Jun/)
15:02:13 <kaz> cpn: my meta question is
15:02:23 <kaz> ... how to handle the remaining issues
15:02:34 <kaz> ... let's have some more discussion offline
15:02:39 <tidoust> [I started to add "needs input" and "needs editor" labels. Not sure whether that's the right approach :)]
15:03:08 <kaz> topic: Media WG updates
15:03:20 <kaz> cpn: would recommend people look into it
15:03:27 <kaz> topic: Next meeting
15:03:32 <kaz> cpn: August 3
15:03:42 <kaz> ... we'll plan something for the meeting
