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

 

minimum>, which is the default setting.

 

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

 

channel bit rate; in this case, the MCU will close

 

the content channel to that participant. To re-

way) to this participant, go to the conference's
