Description

 

 

Content

H.263 Content is shared using H.263 even if some

Protocol

endpoints have H.264 capability.

 

Up to H.264 – H.264 is the default Content sharing

 

algorithm.

 

When selected:

 

Content is shared using H.264 if all endpoints have

 

H.264 capability.

 

Content is shared using H.263 if all endpoints do not

 

have H.264 capability.

 

Endpoints that do not have at least H.263 capability

 

can connect to the conference but cannot share

 

Content.

Sending Content to Legacy Endpoints

The RMX can be configured to send Content to H.323/SIP/ISDN

endpoints that do not support H.239 Content (legacy endpoints) over the video (people) channel, allowing the participants using the legacy endpoints to view the Content as the other conference participants.

Guidelines for Sending Content to Legacy Endpoints

This option is enabled only in MPM+ Card Configuration Mode and Resource Allocation Mode is set to Flexible Mode.

This option is valid when sending Content as a separate stream is enabled in the System Configuration and the flag: ENABLE_H239 is set to YES.

One additional SD (3CIF) video resource is allocated to the conference when Content is sent to legacy endpoints. The allocation is done only when a legacy endpoint is connected to the conference and a Content session is initiated and transmitted via the video channel.

Once the resource is allocated, it remains allocated to the conference until the conference ends.
