Re: [maitai] Roles of Sender and Receiver

Peter,

Unless of course it is a company meeting and the speaker is your CEO!

Something has to decide what screen tunes into what camera, no matter
what.

Question is what can be programmed automatic, and what is allowed to be
manual.
And if manual, what information is available to make such a decision.

Hi, 

I have been pondering possible ways of representing a room configuration
- but I think I need to back up and ask a question about basic interop
architecture. 

In the selection of content on a stream, who is the active decision
making entity, sender - or receiver - or both?

Consider a three display, 3 camera (3d3c) room A sending to a 1d1c room
B. 

Does A offer all three streams to B and let B pick? (This leads in the
direction of dynamic changes based on B, which is powerful but leads us
into continuous control...)
Does A determine B has only one display and select which video B should
get and send only one stream?

IHMO an approach which lets B have control over what it gets is more
powerful. e.g. If I have heard the pitch from the speaker 100 times, I
want to watch the customer and see if they are engaged, rather than
watch the active speaker blather on....

Peter
