Requirements Document

    <inserted> [10]Juhani's comments on adaptive bit rate
    requirements

      [10] 
http://lists.w3.org/Archives/Public/public-web-and-tv/2012Jun/0011.html

    juhani: comments around terminology
    ... not new reqs or use cases
    ... should we keep terms not used in doc?

    clarke: agrees no need to retain unused defs

    juhani: e.g., programme, media track, etc.
    ... some of these unused defs are questionable
    ... suggests new pan-definition for 'adaptive bit rate
    {streaming, content, media}'
    ... should have single def using consistent head term 'adaptive
    bit rate'
    ... suggests defs for 'no abr method preference' and 'open
    source browsers'

    clarke: agrees, will review and implement

    action clarke to review and implement changes to terminology
    related to ABR in reqs document

    <trackbot> Created ACTION-99 - Review and implement changes to
    terminology related to ABR in reqs document [on Clarke Stevens
    - due 2012-07-05].


    <inserted> [11]Juhani's comments on content protection
    requirements

      [11] 
http://lists.w3.org/Archives/Public/public-web-and-tv/2012Jun/0012.html

    juhani: further comments about terminology in CP reqs document
    ... in particular, confusion about distinction between 'content
    protection {method,system,solution}'
    ... proposes to use either/or formulation

    <inserted> [12]Requirements for Content Protection

      [12] 
http://dvcs.w3.org/hg/webtv/raw-file/tip/mpreq/MPTF-CP-Requirements.html

    ddorwin: 4.1.4 says system but should be solution...

    clarke: don't need to make reqs on implementations, do we?

    ddorwin: 'system' is misleading w.r.t. applicability to
    implementation or spec

    <ddorwin> 4.1.10: This sounds like a container requirement,
    which I don't think is necessary.

    ddorwin: 4.1.10 sounds like a container req

    <ddorwin> 4.1.11: Is "determine from the media stream" correct?
    Again, this is also a requirement on containers. FYI, I don't
    think ISO CENC does this.

    <ddorwin> 4.1.12: " determine from the media stream" doesn't
    make sense for errors.

    <ddorwin> 4.1.13: Media Source is not an "element".

    <ddorwin> 4.2.1: What does "provision of tools" mean?

    <ddorwin> some are nits

    ddorwin: what does 'provision of tools' mean?
    ... thinking it means 'the specification provides
    tools/features...'

    clarke: 'provision of tools' probably should use different word
    than 'tools'; suggestions welcome
    ... please send comments
    ... believes the TF is near end of life; should transfer
    responsibility to ...
    ... suggests skipping meeting next week (5th) due to US
    holidays
    ... suggests final review of comments, then either shut down TF
    or go dormant

    ACTION clarke to send feedback on these review comments

    <trackbot> Created ACTION-100 - Send feedback on these review
    comments [on Clarke Stevens - due 2012-07-05].
