    clarke: reviews the agenda

charter review

    MPTF Charter: [9]http://www.w3.org/2011/webtv/wiki/MPTF/MPTF_Charter

       [9] http://www.w3.org/2011/webtv/wiki/MPTF/MPTF_Charter

    clarke: (explains the charter)
    ... to see additional requirements to existing standards, e.g.,
    HTML5
    ... questions/comments?

    clarke: (explains "Basic Information", and then "Scope")

    bob: question about user agent adaptive support

    clarke: comment for bullet points
    ... splicing content into stream

    mark: content splicing is not clear

    richard: could you suggest something more descriptive?

    clarke: clear define is useful

    pablo: HTML5 and JavaScrpt are quite dynamic and flexible
    ... one of the problem is "seamless playback"
    ... might want to synchronize multiple streams on different devices

    clarke: tablet and video, e.g.

    <scribe> ACTION: stevens to add clarification to the second point
    "content splicing" [recorded in
    [10]http://www.w3.org/2011/07/07-webtv-minutes.html#action01]

    <trackbot> Created ACTION-48 - Add clarification to the second point
    "content splicing" [on Clarke Stevens - due 2011-07-14].

    clarke: next, the third point "Browser handling..."
    ... make sense?

    @@@: not quite sure

    Steven_Wright: need some mechanism to support it in HTML

    clarke: issue raised earlier is how to synchronize using JavaScript
    ... next point "Enhancements..."
    ... additional metadata specific to commercial video

    ???: one of the issues is you can use metadata but not obvious what
    type of application signals in metadata

    @@@: you need to be very clear about metadata format

    pablo: what if I want to comment some specific scene of a program,
    not the program as a whole?

    clarke: timed text metadata

    bob: regarding the last point
    ... HNTF raised an issue
    ... on MPEG2 transport layer
    ... that may be one thing we should mention

    <mark> +q

    rberkoff: not necessarily depending on actual location
    ... also distribution of content

    clarke: coming from your local network or some network hierarcy(?)

    rberkoff: it's not a matter of content generated from the source

    <scribe> ACTION: stevens to mention russell's point [recorded in
    [11]http://www.w3.org/2011/07/07-webtv-minutes.html#action02]

    <trackbot> Created ACTION-49 - Mention russell's point [on Clarke
    Stevens - due 2011-07-14].

    <r> ack [Samsung]

    mark: media format?

    clarke: need to clarify at least for the first bullet point

    <scribe> ACTION: stevens to add clarification on media format for
    the first bullet [recorded in
    [12]http://www.w3.org/2011/07/07-webtv-minutes.html#action03]

    <trackbot> Created ACTION-50 - Add clarification on media format for
    the first bullet [on Clarke Stevens - due 2011-07-14].

    aizu: we think video stream from a tuner come from air wave will be
    decoded
    ... and used in <video> element
    ... so we'd like to handle both video data from air wave and stream
    from IP
    ... using same mechanism

    clarke: so you want to think about <video> controlled tuner?

    aizu: yeah

    clarke: maybe in scope
    ... we need to write actual use cases

    aizu: ok. will do

    <scribe> ACTION: aizu to generate use case on tuner [recorded in
    [13]http://www.w3.org/2011/07/07-webtv-minutes.html#action04]

    <trackbot> Created ACTION-51 - Generate use case on tuner [on
    Hiroyuki Aizu - due 2011-07-14].

    clarke: let's move on then
    ... "Success Criteria"

    kaz: as HNTF does, we need to generate a TF level requirements doc
    ... so that we can create an IG level requirements doc by the end of
    the IG charter

    clarke: yes
    ... following the HNTF way
    ... generating use cases is our task
    ... and assign them to use case editors

    <Clarke> Use case template:
    [14]http://www.w3.org/2011/webtv/wiki/MPTF/Use_Cases_Template

      [14] http://www.w3.org/2011/webtv/wiki/MPTF/Use_Cases_Template

    clarke: the above is the template for use case submission
    ... description on the importance, etc.
    ... question?

    Bob: sometimes use cases are very broad
    ... should add motivation etc.

    <scribe> ACTION: stevens to synchronize with HNTF for the use case
    template [recorded in
    [15]http://www.w3.org/2011/07/07-webtv-minutes.html#action05]

    <trackbot> Created ACTION-52 - Synchronize with HNTF for the use
    case template [on Clarke Stevens - due 2011-07-14].

    clarke: will hold our calls every week
    ... issues/actions will be discussed

    bob: where is the address of the mail refrecter?

    <mark> apologies, I have to leave now

    as well [on Clarke Stevens - due 2011-07-14].

    clarke: we've covered except open items
    ... anything else?

    rberkoff: content protection is not able to be in the scope?

    clarke: good point
    ... I didn't include it
