Architecture
->[6]Architecture wiki
[6]
https://www.w3.org/2011/webtv/wiki/Main_Page/Cloud_Browser_TF/Architecture
Close to completing work on the architecture. Thus the chapter
can be considered mainly complete, and freeze it.
Alexandra will finalize the chapter and send it to the group
for review.
Alexandra provided an overview of the architecture chapter.
<scribe> New section on functions added last week.
Agreed that it would be good to have everyone review the
chapter and correct the minor errors that may be detected.
Harrison has some input to be provided on lifecycle.
Yosuke also wanted some explanation on changes (if any) the DOM
tree. It is not changed. This will be added.
Everyone is asked to go though the functions and make updates
as necessary. After two weeks this chapter will be sent out for
final review.
Use Cases
[7]Use Case wiki
[7]
https://www.w3.org/2011/webtv/wiki/Main_Page/Cloud_Browser_TF/UseCases
Now we move to the use cases chapter.
Alexandra asked if, given the architecture chapter, the use
case author could identify with which architecture the use case
could apply?
Colin said that this could be provided in the Notes.
Alexandra noted that we have to provide the requirements
document by autumn.
She used the example of the home networking requirements
document to show how that document added requirements into the
use cases.
She suggest that we also try an describe the requirements
implied by each use case
coiln was asked to convert his submitted use case on tuners
into the template provided
Alexandra proposes adding a separate Wiki page on requirements.
Kaz agrees and suggests adding a link from the requirements to
the use cases. later this can be published as an IG Note
(HTML).
s.suggests/suggests
Colin was asked to send a link to the tuner use case to the
list
Colin described the use case. the requirement is that the cloud
environment must be able to signal to the client to tune to a
channel.
<kaz> [8]Tuner use case wiki
[8]
https://www.w3.org/2011/webtv/wiki/Main_Page/Cloud_Browser_TF/UseCases/Tuner
alexandra: should cloud browser be able to get the tuner state
of the client?
alexandra: it is good to reference tv control api, but it would
be good to abstract it
colin agrees that it could be any api that provides the
necessary feature
colin provided a more detailed explanation of step 1. on a
local browser you retrieve the tuning information from the
middleware by attaching to the multicast stream). in a cloud
browser solution you don't receive the multicast stream. thus,
you need to get the information (by another way. this is called
the backend system in the use case.
colin: asks harrison if this is how they do the translation.
harrison thinks it is reasonable. however, he has a question
about the tv control api. is this the one being standardized?
answer is yes.
harrison: overall description is reasonable. however, the
environment must be prepared to support this scenario. EPG
information is derived from the SI. This requires the
preparation of a backoffice system which retrieves the SI
information
colin: even if we standardize the cloud browser solution, how
the interaction with the backoffice takes place will remain
proprietary
alexandra: put harrison's point in the description
colin: yes, the tuner use case exposes the various points where
there would need to be proprietary interfaces
alexandra: add a user?
colin: that would make the use case more complicated
... this use case makes the application do the work, using the
tv control api to tune to a channel. the only difference with
the local browser case is that the cloud browser has to signal
the client to do the tuning
alexandra: explain what application means - the application
which runs on the cloud browser server, for example
... add the requirements implied by the use case
colin will update based on comments and using the template
kaz: would it makes sense to add two sections - one for the
basic architecture and one for concrete implementations?
alexandra says that the uc sections will identify which
architectures these apply to.
kaz asks colin to add some more modules (e.g., tuner module) to
the architecture
kaz says it would be good to know where the tuner capability
and the epg capability exists and will be handled
alexandra asks if there are any additional issues/ None
identified. She adjourns the meeting.
