The prior meeting minutes were approved without change.
IETF BOF planning
<glennd> Reached out to IETF to provide a BOF (or Bar BOF) of
GGIE on the work we are doing; gain more clarity on related
IETF work; convey that we have some ideas that may be of
interest to them; and to discuss items we have identified that
the IETF might be positioned to work on.
<glennd > Areas of interest: RFC around content identifiers:
Similar content IDs have been defined such as EIDR, Ad-ID, but
GGIE’s concept of Cid is not limited to those two. Could also
include e.g. private for content IDs. There is potential for
work that builds on existing IDs based on some of GGIE’s Use
Cases that were developed as part of the W3C Web and TV WG.
Potential for a look-up system to store/retrieve information
related to content based on identifiers.
<KilroyH> Elaboration of ultraviolet features as relate to the
proposed GGIE BoF. [6]http://www.myuv.com. UUIDs identify bit
streams but don’t give an indication of relationship between
works, metadata. Suggest doing a survey of content metadata
that’s out there as a reference
[6] http://www.myuv.com/
<glennd> Haven’t heard back from IETF about whether or not this
will be a formal BoF or a bar BoF or what.
Review of TPAC Use Case slide deck
<glennd> Slide deck is being prepared by Bill Rose as a
showpiece for GGIE at a potential informal session during TPAC
in Sapporo. Basic idea is columns are actors with description
of what each actor does. Is this format OK? Changes, new
format?
<?> Need to capture difference between static adaptive and
dynamic adaptive systems
<KilroyH> Good format for the basic UC-1. Suggest adding colors
to illustrate differences in build.
<glennd> Does this make sense for the audience?
<LeslieD> need to look at how it works for more complex UCs.
<glennd> UC-1b. Label columns with actors. Moving to UC-2.
<KilroyH> Not sure what this adds to UC-1b?
<glennd> Client is doing control and doing byte fetch. Not just
simple start the flow.
<LeslieD> Format is working so far. Adding labels and colors to
show how they change from the previous will help.
Action Item: Bill Rose to label and color code actors and
highlight what’s new.
<NiloM> Lower right does not fit the actor/column paradigm.
<glennd> Moving to UC-3. Adds extraction of the Cid. 3 ways to
extract it. Metadata, embedded A/V watermark, extract A/V
fingerprint.
<BillR> This one didn’t fit into the previous format.
<glennd> Looks like we are evolving from metadata to watermark
to fingerprint. Stack them instead of using arrow.
<glennd> Maybe we don’t make this a UC but a foundational idea
from a UC. Get rid of the arrow in the background. Looks like
the format is holding up with some edits.
Action Item: Bill Rose to change the slide to eliminate the
confusion.
<KilroyH> Suggest keeping the UC slides simple, show difference
between each, focus on user experience. Select assets, move on
to trick play, not sure what UC-3 adds to user experience.
Getting into network mechanics will get complex and cause
confusion and comments on all of the ways it could be done.
<glennd> Some people will want to get down into the engineering
details but the IG focus/scope is not how to do it but what we
want to be able to do.
<KilroyH> Suggest a title for the presentation might be “here
are the problems we are trying to solve”.
<glennd> We will give some of the background on what we are
doing, scope, etc. Then move to the UC slides. Waiting to hear
from the chairs. Scheduled to meet on Monday Oct 26th. There
will be remote access capability.
<glennd> Going forward we will take the rest of the use cases
and put them in this format; circulate to this group for review
and comments. Oct 7th meeting will be a full 90 min, as we’ll
walk through the whole deck as it is intended to be presented
in Sapporo No call on October 21, 2015.
Next meetings
<glennd> Next call is Wed Oct 7 (last call before Sapporo
TPAC). No call on Oct 21 or on Nov 4th.
<glennd> Meeting adjourned
