Re: [maitai] Roles of Sender and Receiver

Charles,

That sounds consistent with the way I have been thinking about it too.  B might also want to ask for a particular stream at a particular time, as in Peter's example of wanting to see the customer even though the customer isn't speaking.

The way I have been thinking about it, A would advertise what cameras it
has and ways it can present them to B. B would then be able to select
the camera and/or representations it wants.
As a simplified example, A could advertise the following:

I have 3 cameras, left, center, and right.
I can provide these as:
- 3 separate streams
- 1 active speaker switched stream
- 1 stream composed of the three

Of course there would be audio and many other things to consider, but
hopefully that gets the general idea across. This allows B to have as
much of as little control over what it receives as it likes, and it
should be able to change mid call.

Cheers,
Charles
