<Karen> Hi Daniel, I thought we were doing a Skype call today and did not see you there :(
<ddavis> No, I'm ready in TEAM2 but I can do Skype instead.
<ddavis> I stop Zakim and switch to Skype.

Glenn did a roll call
<_M_> _M_ is Mohammed Dadas
<glennd> Glenn Deen
Bill Rose attending
<ldaigle> Leslie Daigle
<azamlerc> Andrew Zamler-Carhart, Cisco
Glenn called for any changes to the 1/14/15 minutes
<jianz> jianz: jian zhao
No changes - adopted without change
Glenn called for any changes/additions to agenda
There were no changes to the agenda. Adopted without change
Glenn discussed the Face to Face Meeting
Glenn suggested that if the mini TPAC on April 13 is not a good choice.
<jgiacalo> Jean-Pierre Giacalone, Intel Corporation, joined IRC
<ldaigle> I seem to have plane tickets booked for dallas
Glenn asked if the IETF meeting in Dallas March 23rd would be good
<azamlerc> I will be in New York, so could probably fly to Dallas.
<jgiacalo> Difficult to grant for me but possible
Several attendees said they would or could be there. Glenn will check for meeting space/options
<azamlerc> Boston is good for me!
He asked for members to get back to him if anyone wanted to host a meeting and to propose alternative venues.
Glenn: Should advertising use
cases be added?
... Also potentially for measurement?
?? There are 2 types of advertising mechanisms
Would be good to be able to converge the 2 means of delivery
Glenn asked the speaker to post the 2 standards he referenced
<NiloMitra> VAST by Internet Advertising bureau and SCTE-130 series
Glenn: Do they include AdIDs?
There are best practices as to how to track. Not certain if there are AdIDs.
Glenn: International/Global stds?
Yes: SCTE is seen as global. The other is a consortium but has global reach.
mark_vickers: It is in the scope
of the Web&TV IG but might not be in scope for GGIE.
Advertising is normally not created with the content and will
vary from dist to dist.
... Encourage Web&TV IG to look at it.
Glenn: In scenarios of E2E delivery, some do include ads. When looking at delivery ads might affect delivery of content. Also the metadata assoc with content and ads could affect how the delivery is done.
mark_vickers: It is the chairs call.
Glenn: Lets continue discussions
on ads and determine later if those use cases should
remain.
... More discussion? - No more discussion.
Glenn: IPv6 offers new scenarios
not available in v4. Some scenarios might not be possible using
v4. Should we describe the scenario or make it clear it is only
possible in v6?
... Comments
Bin: Content dist thru CDN, etc. to home will be impacted. So we should identify the unique features of v6 that enable or require v6 to accomplish. If there is a gap we should identify.
azamlerc: Should support v6 as much as possible. v6 will not be unbiquitous but if something is operating in a specific environment that s v6 only we can identify that. Also identify where v4 would be supported.
Glenn: Regarding mobile, are there things we need to do to support.
Yes. There are a lot of discussion on v6 on mobile
Glenn: We should reach out to get
more research on mobile to determine if there are any
issues/interactions between v4/6 with regard to mobile.
... Are there any volunteers to start the research? Yes: Andrew
Cisco volunteered.
<azamlerc> What kind of support for IPv6 is there on mobile networks? Andrew Zamler-Carhart, Cisco to investigate.
Glenn: Are there any other scenarios for caching we should incorporate into the discussions?
[ There were no suggestions. ]
Glenn: CDNi - cooperation between upstream/downstream CDNs?
[ No responses. ]
Glenn: CDNi within IETF - the work appears to be winding down. Glenn will touch base to determine if there is anything that we should address.
Glenn: Discussion have been taking place on how to transition from mobile to WiFi as a person enters home/work, etc. Presents a problem if the connection is based on an ID/IP address,etc. Could interrupt storage/cache being used during the original session. What do we need to be aware of
Ans: Touches work at Cisco. Asking questions about how devices can support severa different network connections. IPv4 typically only has one interface. v6 can support multiple connections. If you have several IP addresses, there might be a policy issue directing the choice of IP.
Glenn: DNS could be a more complicated selection process. Might want to add on DNS issues in use cases. Choice of delivery channel needs to be addressed in this scenario.
Glenn/JP-Intel: If we bring in IoT, how does that change the situation?
JP: Want to reach displays anywhere? Refrig, etc.? Wearables?
Bill_Rose: Screen synchronization across devices of different capabilities?
mark_vickers: Some work is being done on second screen. Some will be IoT devices. GGIE is not stds body but might do work that applies to IoT devices so it is appropriate but not the same as addresing all IoT device issues.
<azamlerc> Have a look at the W3C Web & TV project called Shared Motion for synchronizing video across multiple screens.
<azamlerc> Use Case Ten – Sync Among Browser- and non-Browser Devices
?? W3C WebTV IG is doing work on shared motion.
?? Is this a part of content creation/dist or part of playback?
Glenn: What is shared motion.
Link was posted in IRC. Web browser on several screens allow you to get frame accurate playback on multi-screens. Frame Sync.
<ddavis> Latest Shared Motion discussion
Glenn: Summarized. In general IoT
are in scope for GGIE, but we should not get involved into
areas that are not a part of E2E content delivery. There might
also be overlap with other work being done in W3C. We should be
aware of that work but stay focused on E2E content.
... Propose a breakdown use cases into priorities and how they
are linked even if separate. e.g. categories of related use
cases. Will make it easier to later look at related metadata
aspects of the use cases.
This was for agenda item 6.
Glenn: multiple cameras capturing
same scene different angles. Needs metadata to
coordinate/identify session, etc. for capture, storage,
editing, etc. Even consumers are doing this today.
... As the content moves through steaming, storage, editing,
packaging and encoding, archiving, etc. the metadata needs to
be created, follow and will be added/altered by different
actors yet be linked.
... Some metadate may be commercial - sold/licensed, etc.
... Used in search, discovery.
... Need to look at workflows
Glenn - continued: Need to examine home/consumer network scenarios
Glenn: Is this a good grouping -
good place to start? - Yes
... Is there anything else anyone wants to discuss?
Mike: Are you asking people to start writing use cases?
<Zakim> kaz, you wanted to ask if we want to have a joint meeting with the WoT IG during TPAC 2015
Glenn: Suggest by submitting use
cases and ask for volunteers to explore them.
... Need to get some "seed" scenarios to start the
discussions.
... Either send your scenarios to the WIKI or submit to Glenn.
Then submit your list of any you want to explore. At the face
to face we can start to flesh out the higher priority use cases
together.
... Next meeting, Feb 11, 2015.
Kaz: Que: Wondering if we should speak to IoT IG about potential of a joint meeting?
Glenn: Might be premature.
Perhaps after the F2F meeting we will have a better idea of
what we need to do in this area..
... Will address this after the F2F meeting.
<glennd> bye all
<ldaigle> thanks — bye
End of call.
