      * [8]Summary of Action Items


    Clarke: review bugs and first draft of reqs doc -- anything


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

    Clarke: no new bugs recorded -- any new ones?
    ... any status changes on the 7 bugs we are tracking?

    giuseppe: some comments on one of the bugs

    Clarke: anything we want to cover on those bugs?

    guiseppe: not for now

ADB requirements

    Clarke: just sent ADB reqs doc -- this will be submitted to
    HTML Media TF
    ... follows the MPTF template. not on a common repository yet,
    sent as an enclosure
    ... GoToMeeting to follow along
    ... two main things to cover today ...

    … reqs listed form our dashboard page ...

    … section for more comments -- not filled in yet ...

    … section on security and next steps ...

    … part to expand on today is terminology.

    Clarke: need to get additional terms that need to be brought up
    in the doc
    ... any terms that are related to ADB that need to be added?

    <kaz> [10]initial draft of MPTF Requirements for Adaptive Bit
    Rate Streaming


    Clarke: we could add a definition for ADB itself
    ... probably "manifest file"

    giuseppe: list the open sources for this document as well

    Clarke: few definitions from the proposal itself
    ... "common time base" ?
    ... what about "trick play"?

    John_Simmons: for a doc intended to be requirements, any
    definitions not around objects you are trying to articulate are
    not required
    ... a lot of things mentioned will fall out of the proposals
    created and attempts to create a solution for the HTML WG
    ... main thing is to get the reqs clear

    Clarke: get things specific to a proposal and those should be
    in the proposal
    ... what about "user agent"?

    John_Simmons: this is a well define term in the HTML WG -- does
    not need to be defined

    Clarke: any other terms to define?
    ... please take a look at the TOC and see if anything is there



    Clarke: <reading the TOC>

    joesteele: definition of "track"?

    Duncan: authors of the spec has Adrian instead of Kilroy

    Clarke: any other comment on the outline?
    ... back to the agenda

new bugs or TF items?

    Clarke: anything else to discuss here?

    John_Simmons: the TF has been proposed in HTML WG, comments
    have been posted, similar to previous discussion there are
    people opposed to there even being a TF ...

    … I encourage people interested in seeing this work to express
    their support for creation of this TF ...

    Mark_Vickers: do we respond to the CFC?

    John_SImmons: yes - just respond that we support the creation
    of this task force

    Clarke: I thought we had gone through this -- what determines
    whether a TF gets formed? simple majority? feedback? ...

    … how do we know when enough support has been given?

    John_Simmons: it is not a forgone conclusion that TF will be

    <Clarke> ?q

    <glenn> there aren't really any rules

    <glenn> it is a matter of the chairs to determine consensus

    kaz: consensus is the process

    <glenn> consensus does not mean unanimity

    kaz: it would be useful to send out supporting message

    Clarke: seems unlikely to be agreement. does a vote happen?

    kaz: yes -- final resolution is a vote

    <glenn> no vote will occur if the chairs feel there is no need
    for it

    Clarke: companies get to vote?
    ... expressing support is useful and encouraged, but final
    decision is subject to ambiguity

    <glenn> the response date already passed

    Mark_Vickers: I am going to respond today and I encourage

    <glenn> and it only asked for objections

    Clarke: any other discussion?
    ... any other topics?
    ... short meeting today. Will update the docs and send out the
    links for review.

    <kaz> [ adjourned ]
