TANDBERG MSE 8510, MCU 4500 manual by the Display content in normal video channel

This field sets which video codec is used for conferences' content video streams.

A single content video stream is used for each conference, and this stream will be sent to all viewing endpoints. If an endpoint is unable to receive content video using the codec configured here, no content channel will be opened to that endpoint.

	If you do not wish to exclude endpoints from
	viewing the shared content video channel in a
	conference, make sure this is set to <no

	Where an endpoint cannot, for whatever reason,
	receive the content channel as an additional video
	channel, the MCU can show the content channel
	as part of the main video channel. That is, the
	participant will see the content as a pane in the
	conference layout. This functionality is controlled
	by the Display content in normal video channel
	setting (see below).
	Note that during a call, an endpoint can send a
	'flow control message' to the MCU that could
	cause the MCU to reduce the bit rate to that
	endpoint to below the configured Minimum content
