Description
The Content Rate drop-down menu is displayed next to the Content Resolution
drop-down menu when:
• H.264 Cascade and SVC Optimized is the selected Content Protocol
and
• CustomizedContentRate is the selected Content Setting.
The Content Rate is dependent on the MCU type (Realpresence Collaboration
Server with MPMRx or Realpresence Collaboration Server 1800) and can be up to
66% of the conference line rate. In MCUs with MPMRx cards the Content Rate is
limited to 2048 kbps, while when used with the Realpresence Collaboration Server
1800 the Content Rate is limited to 4096 kbps.
When enabled (default), Content can be sent to H.323/SIP/ISDN (Collaboration
Server (RMX) 1500/2000/4000) endpoints that do not support H.239 Content
(legacy endpoints) over the video (people) channel. For more information see
Sending Content to Legacy Endpoints (AVC Only)
Notes:
• This option is enabled in MPMx and MPMRx Card Configuration Modes only
(Collaboration Server (RMX) 1500/2000/4000).
• When enabled, an additional HD video resource is allocated to the conference.
• This option is valid when sending Content as a separate stream is enabled by the
System Flag ENABLE_H239 set to YES.
• Select this option when Avaya IP Softphone will be connecting to the conference.
• In Video Switching Conferencing Mode the Send Content to Legacy Endpoints
option is disabled (Collaboration Server (RMX) 1500/2000/4000).
• If the Same Layout option is selected, the Send Content to Legacy Endpoints
selection is cleared and is disabled.
• Once an endpoint is categorized as Legacy, it will not be able to restore its
content to the Content channel and will receive content only in the video channel.
