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]

"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

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

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
