<Clarke> Here is today's agenda: http://www.w3.org/2011/webtv/wiki/MPTF/Agenda_Telco_7th_July_2011

clarke: reviews the agenda

<Clarke> MPTF main page: http://www.w3.org/2011/webtv/wiki/MPTF

charter review

MPTF Charter: 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 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 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 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 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: 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 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

kaz: in the "Communication" section (http://www.w3.org/2011/webtv/wiki/MPTF/MPTF_Charter#Communication)

<scribe> ACTION: stevens to add ML address to the logistics page as well [recorded in http://www.w3.org/2011/07/07-webtv-minutes.html#action06]

<trackbot> Created ACTION-53 - Add ML address to the logistics page 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?

... maybe need another TF

rberkoff: ok
