didn't.
Thanks,

actions
giuseppe: start with 16
russell: should start with 17 first and then go back to 16
<giuseppep> ISSUE-17?
<trackbot> ISSUE-17 -- Use Case: Home Network Enabled User-Agent --
raised
<trackbot> [7]http://www.w3.org/2011/webtv/track/issues/17
[7] http://www.w3.org/2011/webtv/track/issues/17
giuseppe: ok
russell: question about password
... discussion on security
... password is managed locally
... rather than centrally managed
giuseppe: think it's fine
... you can split media player/recorder
<JanL> +q
giuseppe: probably better to split them
russell: fine
... separate use cases eventually
giuseppe: you can put note on DLNA/UPnP in not the use case but
additional note section
russell: did so
giuseppe: ok
russell: five categories
... user agent. requirement for generating content
... for home network
->
[8]http://www.w3.org/2011/webtv/wiki/HNTF/Home_Network_TF_Discussion
s/UPnPHomeNetworkUA Russell's writeup on the Wiki
[8] http://www.w3.org/2011/webtv/wiki/HNTF/Home_Network_TF_Discussions/UPnPHomeNetworkUA
russell: (explains Scenarios section)
...
... requirements for Media Player device metadata like date, etc.
<JanL> clarke is speaking
clarke: special case for buffered device?
russell: add clarification
jan: numbered list would be easier to read
russell: usually use numbered list...
[ Media Server device ]
russell: (explains) Media Server device
jan: managing locally on your PC?
russell: user agent is used for media server
... it exposes contents to home network
jan: administrating metadata for the content?
giuseppe: some content from YouTube, and another content on local
USB
russell: can capture the comments
bob: is that more requirement on how to implement media server?
... interaction in home network
russell: correct
... media server is not necessarily implemented using a specific
method
[ Recording device ]
russell: capture content based on time/date
... and based on EPG
clarke: difference between EPG-based and metadate-based
russell: @@@
bob?: the recording device should provide notification
russell: yes, the device should provide notification on recording
status, schedule change, future activity, etc.
... for example, if I don't specify channel, the recording device
should show several choices
... recording instructions, etc.
<JanL> were we going to limit issues to 10 minutes on each issue?
<JanL> this is a broad issue so it needs more time
<davidmays> -q
<JanL> +q
[ UA commands other media oriented devices ]
russell: control camera angles, etc.
@@@: security?
giuseppe: we can discuss security more
[ Future device classes ]
giuseppe: let's continue the discussion by email
... you suggested some extension is needed
... what kind of extension is needed should be discussed
... good to point out what the missing pieces are
russell: will do
... there is some concern metadata can't be delivered using DLNA
etc.
giuseppe: will continue the discussion by email
russell: ok
jc: not sure if this could be done in specific situation
russell: I think it's generic use case description
... not depending on specific implementation
giuseppe: it's still early stage, so don't need to discuss detailed
methods for messaging, etc.
... if you need specific APIs or messaging mechanism, that should be
separate discussion
<JanL> the queue system is not quite working well
kaz: we should split issue-17 into 5 separate use cases, shouldn't
we?
russell: will do
<jcdufourd> my earlier question to Russel was: is the issue-17 about
defining a set of APIs including one to list available home network
media server, or is it about having a generic API that allows to do
all the described cases
jan: (missed first two comments...)
... security portion?
igarashi: related to comments from Kaz and Jan
... kind of confused
... what is the point of this use case?
russell: originally what currently UPnP does
... but I removed "UPnP specific portion" from the use case
igarashi: all of the use cases are actually examples of user's
requirements for basic framework
... in that case, you don't have to split this big use case, but
simply re-define a generic use case including the current topics as
examples
russell: what kind of format would fit?
... how could I mention metadata handler?
... it's kind of complicated
igarashi: you don't need to explain the details of methods for your
use cases
... I think the detailed description in this "Home Network Enabled
User-Agent" use case
... it's rather examples
... maybe you should explain a "Basic framework for home network
enabled UAs"
giuseppe: the point is how to enable which capability
russell: would care of the details of implementation mechanism
igarashi: we should clarify what kind of messages should be invoked
at which devices/servers
... for example, what kind of metadata, e.g., title, is needed
... that is use case
giuseppe: (we're out of time) so let's continue the discussion on
the mailing list
jan: can agree removing mentioning UPnP, etc.
... relationship with 24?
giuseppe: how to merge with that?
jan: relationship w/ 17?
giuseppe: it would be better to wait for a specific WG
jan: there is no exact APIs for local function like DLNA
... we have DLNA stack and also guidelines
giuseppe: let's talk by email how/whether to merge with 17
jan: ok
<davidmays> bye
giuseppe: will continue discussion by ML
<Clarke> bye
giuseppe: next week we'll start with 18
