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
