<scribe> Scribe: Daniel
<scribe> scribenick: ddavis
Bin: We have started second
iteration of the use cases and requirements.
... The deadline is the end of May for use cases.
... At the end of June the use cases will be finalised. The end
of May is for use case submission.
... The end of September is the deadline for the requirements
and gap analysis.
... This allows for some slippage before the end of the
year.
Giuseppe: Please could you send a reminder of this schedule to the list?
Bin: Sure
<scribe> ACTION: Bin to send a reminder of the schedule and process for use cases/requirements and gap analysis [recorded in http://www.w3.org/2014/04/30-webtv-minutes.html#action01]
<trackbot> Created ACTION-192 - Send a reminder of the schedule and process for use cases/requirements and gap analysis [on Bin Hu - due 2014-05-07].
Bin: Also, we have a TV Control
CG established with representatives from about 12
organisations.
... Kaz and Daniel are helping with logistics
... We also have contributions of existing API proposals from
other companies and organisations.
Giuseppe: As a reminder to
newcomers, Community Groups are groups that are set up to
discuss specifications but cannot create standards - Working
Groups do that.
... You don't have to be a member of W3C to join Community
Groups
... The TV IG will keep in touch with relevant Community Groups
to track progress
... Community Groups can create specifications but they are not
endorsed by W3C. If they wish, they can send specifications to
a W3C working group to put it on a path to standardization.
Giuseppe: Mark Vickers is not on
the call so we'll skip this.
... I'll speak to him separately about drafting a response.
Giuseppe: The DAP WG sent a
request to us asking about feedback for the Network Service
Discovery API
... There has been some discussion on this and I've sent some
liaison letters. I haven't received responses yet but if I get
any I'll forward them to the DAP WG.
<giuseppe> http://lists.w3.org/Archives/Public/public-web-and-tv/2014Apr/0025.html
gmandyam: Regarding the ATSC liaison, we'd like to know roughly when the Tuner (TV Control) CG expects to complete its work, because that could effect ATSC 3.0
Giuseppe: I'll work with you and Mark to discuss this.
Giuseppe: On the last call we
discussed testing and what material is available for W3C
testing.
... This discussion is now happening and some questions from
the last discussion have been addressed.
... The testing group would be able to help with guidance on
how to use W3C tests and testing material.
... We could start with a conference call and see if there's a
need for a face-to-face meeting.
So Vang: That seems reasonable to me.
Kaz: Who are we talking with from the testing activity?
Giuseppe: Robin and Tobie should be on the call to help answer questions.
Kaz: Mike Smith is also working on HTML stuff
Giuseppe: You (Kaz) and Daniel
should also be involved. We should discuss this then reach out
to the testing group to arrange the call.
... If anybody in this call or on the TV IG mailing list is
interested, please get in touch. Don't be afraid!
Kaz: There was some discussion on
accessibility at the Munich TV workshop.
... This is in addition to just captioning
... Daniel and I spoke to W3C staff from the accessibility
activity
... They agreed we should work on more that just captioning for
accessibility
... We should bring our ideas and use cases to the media
accessibility task force.
... They can review them and can offer guidance to us. They
also have media accessibility guidelines.
ddavis: Mark from the accessibility activity has just joined us.
MarkS: We're excited to help any
way we can.
... The media accessibility sub-group can make sure
accessibility is addressed.
Giuseppe: The TV IG is not a
Working Group so we can't create standards. We're also not
working on anything specific right now.
... But it's good to have this channel open and as soon as we
start discussing use cases that are relevant we'll ask you to
be involved in the discussion.
... We are also discussing non-relevant things, though, such as
testing.
MarkS: I was wondering if it's useful to go through the first iteration of use cases. We could provide feedback that could be useful when thinking about the second iteration.
Giuseppe: The first iteration
resulted in a TV Control Community Group so maybe it's better
to be involved in that CG.
... The other use cases didn't really have any follow-up so
maybe it's not that useful to look into that.
MarkS: OK, the TV Control CG sounds like a good place to start.
Giuseppe: I'll let you know where to start.
<scribe> ACTION: Giuseppe to send details of TV Control CG to Mark Sadecki [recorded in http://www.w3.org/2014/04/30-webtv-minutes.html#action02]
<trackbot> Created ACTION-193 - Send details of tv control cg to mark sadecki [on Giuseppe Pascale - due 2014-05-07].
Zak: We'll keep in touch with Mark as well
Giuseppe: Also if Mark thinks there are things that are missing in our new use cases then it would be good to hear that.
<MarkS> Media Accessibility User Requirements
MarkS: Also, we have media accessibility guidelines. They were started a few years ago but are now mature and very close to completion. It would be good for the group to review these.
Yosuke: At the workshop, David
Singer brought up this topic. He told us that the TV industry
is pretty good at subtitles/captions thanks to
regulations.
... But it's time for us to think about other types of
accessibility.
... At the workshop we didn't have time to discuss this further
so it would be good to include David in this discussion.
... There are many regional regulations so it's important to
consider where to start with this.
Giuseppe: Yes, I'd encourage anybody to submit ideas and contributions.
<yosuke> http://lists.w3.org/Archives/Public/public-web-and-tv/2014Apr/0079.html
Yosuke: I just sent a mail to the
public list.
... This was proposed by Japanese TV broadcasters.
... The main point is that lessons learned by them is that
performance needs to be improved.
... This is hurdle, blocking expansion of TV apps.
... I put a list of potential deliverables.
... We can have a list of benchmarking software used by the
industry.
... We could then make a proposal for specific APIs if
necessary.
... If we have other interested parties then this Interest
Group is the best place to discuss this.
... If not, then the Web Performance Working Group might be
better.
... So does anybody on this call have any questions?
... After this call I'll send some ideas and how to proceed
with this topic within W3C.
... Then we can start some actual work in two weeks or
so.
... Any questions?
Giuseppe: If the broadcasters you mentioned could put together the results of their work then that can indicate what APIs might be missing.
Yosuke: You mean start something in the IG?
Giuseppe: Yes, at least what the issues are or things that are missing.
Kaz: Yosuke, do you want to create a specific task force for this?
Yosuke: No, we don't need to
create any more task forces.
... My question is whether to start this discussion in the IG
or in the Web Performance WG.
Giuseppe: As this was brought up
at the TV workshop then I think the TV IG is best.
... Any information you have collected from Japanese
broadcasters could be shared in this IG, for example on the
wiki.
Yosuke: So we'll start with collecting some information in this Interest Group and then after that we can expand somewhere else if necessary.
Kaz: Bin has already started to
collect the second iteration use cases. You would also like to
start discussion on the performance topic.
... In that case, would it be better to have two separate phone
calls?
Giuseppe: I don't think there's enough work to discuss this separately. Let's keep everything here.
Yosuke: I don't want to use a
conference call at the early stage - just wiki and mailing list
because of the timezone differences.
... So we don't need to set up a separate conference call for
this (for now).
... I can speak with other stakeholders during these IG calls
if necessary, to make them aware of what we're doing.
Kaz: As long as we work together there's no problem.
Giuseppe: Any other comments?
gmandyam: The W3C normally
doesn't do minimum performance specs or guidelines. I'm
assuming there won't be minimum performance proposals resulting
from this.
... Is that correct?
Yosuke: Correct. We're talking
about how to measure actual performance of existing
environments - not how to impose minimum performance
standards.
... But measuring application performance is really important.
We'd like to share best practises.
... If we need new APIs for user agents then we'll ask the Web
Performance WG to define such APIs.
Giuseppe: There's already a WG working on it but we can say if we think something is missing.
Giuseppe: Is there anything else to discuss?
Pierre: How is this group related to community groups? Is there a formal relationship?
Giuseppe: There isn't an official
relationship.
... For the media in-band tracks CG it was spontaneous.
... The TV Control CG was created from discussion in this group
so we've asked them to keep in touch and report on their
progress.
... The relationship is just to let us know what's happening in
related community groups.
... Technical work has to happen in CGs or WGs. The only thing
we can ask is for community groups to give us an update.
Actually, we should do this for the Timed Text CG.
... If you'd like closer communication then it's best to join
the CGs.
... The next call will be in 2 weeks. I'll send a reminder in
advance. Let me know if you'd like a calendar invite.
... Speak to you in two weeks - meeting adjourned.
<giuseppe> thanks daniel for scribing and sorry for picking you ;)
