Review of the high level GGIE diagram

   <glennd> Ingest was added to the diagram per last meeting
   discussion. Also added Enterprise/CDN operated edge cache
   bubble to the Smart Edge (Glass of Viewing)

   <nilo> Shouldn’t CDN be added to the Distribute bubble in Core
   block?

   Action Item – Glenn to add CDN to Distribute bubble in Core
   block

   There were no other comments

Discussion on Cache UC-1 Cache Query

   <glennd> A viewing device is accessing content from a source on
   the network. A cache exists on the network which may have some
   or all of the content elements. The viewing device connects to
   the cache and queries the cache for the content source using a
   URI which contains the content identifier and segment
   identification for the sought content element. If the content
   element is not in cache, the device will get the content from
   the original source Caches assist in obtaining content. May be
   multiple caches. Caches may have all or part of content. If
   viewing device does not find content on an advertised cache, it
   will get the content from the original source.

   There was no further discussion

Discussion on Cache US-2 Cache Discovery which builds on Cache UC-1

   <glennd> A viewing device is accessing content from a source on
   the network. A cache exists on the local network but the device
   is not aware of the cache. The cache advertises itself on the
   local network so that it maybe discovered by devices. The
   device finds the cache and adds it to its list of known caches.
   The viewing device connects to the cache and queries the cache
   for the content source using a URI which contains the content
   identifier and segment identification for the sought content
   element. If the content element is not in cache, the device
   will get the content from the original source . In UC-1 there
   is no discussion on how device finds a cache. Cache exists on
   local network, advertises itself.

   <digitaldale> What constitutes a cache? How does it advertise
   itself – as what?

   <nilo> Since it is on local network, there are some local
   network services that do advertise themselves like UPnP/DLNA

   <glennd> DLNA has a content source but is this really a cache
   or a source?

   <nilo> A device can identify itself as a source. DLNA has
   concept of gateway or media server that caches content. Local
   devices can discover and obtain media. The media server is
   essentially a cache since it may or may not have the complete
   file.

   Action Item: Glenn will add note on DLNA and any other services
   that may fall into this category in the gap section.

   <glennd> We can go into it further when discussing UCs in more
   detail, gap analysis

   <glennd> Submit additional UCs as members think of them

Discussion on Streaming-UC-4 Manipulating streamed content

   <nilo> Content items may be interposed within other content to
   create the version that is streamed to the end consumer such as
   linear TV, video-on-demand, where previews and advertisements
   can be placed before, after and within the main content item.
   The number, position and length of these interstitial content
   items are determined by business agreements between the actors
   identified below. There are standards such as Ad-ID, EIDR, that
   can identify the ad and content respectively. SMPTE is working
   on a specification to insert such identifiers into content
   items. SCTE has defined specs for signaling position of
   interstitials and alternative content.

   <glennd> I understand SCTE only applies to broadcast, not web
   TV

   <nilo> Not OTA broadcast but by cable, others.

   Action Item: Nilo will add note Streaming UC-4 as to what types
   of content SCTE is applicable to.

   <glennd> For user generated content, are there standards that
   can be used? YouTube allows ads between content items, not
   within the content

   <nilo> Could be done in principle but not used.

   Action Item: Nilo will add note to Streaming UC-4 about
   standards for e.g. inserting ads in YouTube content.

   <glennd> Could see the need for longer form user content

   <glennd> Is there any additional information that should be
   passed onto GGIE members about the upcoming Web and TV IG TPAC
   meeting?

   <kaz> Time, date. Speak to chairs of TV Content, others, about
   items they may want to add to the meeting

   <glennd> Need to start thinking about issues for 2016 that GGIE
   should address so we can begin to schedule

Next meeting

   Next call: July 29th at 11:00 AM ET.

IETF meeting

   <glennd> If anyone will be at the IETF meetings in Prague the
   week of July 19 please contact me.
