Sanjay presents the slides.
Leslie: Please ask questions now. This is nearing WGLC.
Eric Vyncke: I would suggest that WGLC get forwarded to other working
groups like TSVART.
Glenn Deen: We think we are complete. But people may not be aware that
this is happening in their environment. So people should look at the
work believing these things are in fact happening in their environments.
Lenny presents slides.
Note: Side Meeting on this topic on Wednesday, November 5th from
11:00 to 12:30.
Glenn: I can't come to the side meeting, but I don't see rights
management or geofiltering, which is very much connected to this.
Multicast doesn't handle these well. Broadcasters may use different
encodings as well.
Lenny: My naive answer to this is decryption. So you can join wherever
you are and you won't have the decryption key if you don't have the
rights to one.
Glenn: You are a good engineer and have gone into solution mode. Put it
in the agenda for discussion.

Roger presents slides.
Abdelhak Bentaleb: What are you using to actually direct the content
steering? Is it dynamic? How do you decide to switch?
Roger: It really depends. There are two camps: static or operationally.
But people don't always tell us what they are doing. It's kind of
opaque. It's certainly easiest to just assign weights statically.
Leif: There's an explicit TTL in the manifest in the JSON. How does that
ineract with max-age? Why aren't you using max-age in the cache-control
in the HTTP.
Roger: Steering tends to be independently implemented. The payload of
the steering server don't usually demand or use caching. If we get to
the point where steering manifests are cached, we can look at it.
Ali Begen: Should this working group publish this RFC?
Eric Vyncke: A standards RFC would be stronger, but not in tihs room.
This is out of the charter for this WG.
Leslie: I am not sure there is a desire to get a lot of WG feedback.
Roger: It's perhaps up for discussion.
Abdelhak presents slides.
Jana Iyengar: This is a large area. We're looking at different QUIC
implementation. Not all of them are by default tuned for video delivery.
MVFST is tuned for video delivery, so be mindful of what they are
tuned for. It may help to allow you to focus down on fewer
implementations.
Abdelhak: It's something we're considering. The scope is very big, but I
want to promote the cross-layer sharing.
Leslie: There are many implementers in the meeting, you can find them
for good conversations.
Glenn presents slides.
Jana: How would one participate in these meetings? How would I get it
and how would I engage?
Glenn: If you're an SVTA member, you can get them from the internal
system. Meetings are at 9am Pacific.
Eric: Thank you Kyle for his service as chair. I am looking for a new
chair.
