Umesh,
The video mixing scenarios describe typical video conferencing scenarios. An
participants with the right privilege level may select the screen layout he
wants to have. The selection may be for his own view or for the whole
conference view. The availability of such functionality per participant or
per conference is dependent on the mixer functionality. This functionality
is not saying what is the content (whose video is mixed) but on the layout.
Layout may be static during the conference or may be changed dynamically
based on user selection (e.g. start with a single view and request a quad
view later) or the layout can change automatically based on the number of
participants in the conference.
The selection of the layout is independent from the selection of which
stream is seen in each sub-window

Hello,

In section 4.1 of the draft ( Video mixing scenarios ), it says " For video
the user selects one of a set of pre-defined video presentations offered by
the server". Does it mean that end user in the conference knows what all
streams the server can offer? Does this pre-defined video list changes
dynamically ?...For example Particpant A is getting video of particpant B,
but decides to watch a mosaic of participant B and C, it should be able to
do so...The server should be able to mix the streams of B and C and send one
stream to A...

This document describes SIP conferencing scenarios.  It will describe
   basic and advance conferencing scenarios.  These conferencing
   scenarios will help with definition and evaluation of the
   requirements for SIP conferencing framework and the protocol
   associated with the framework.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
