Sending Content to Legacy Endpoints

2-38
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 legacy endpoints to
view Content instead of the other conference participants.
Guidelines for Sending Content to Legacy Endpoints
• This option is enabled in MPM+ and MPMx Card Configuration Modes
only.
• 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.
• Additional video resources are allocated to the conference when
Content is sent to legacy endpoints:
— In MPM+ mode, an additional SD video resource is allocated.
— In MPMx mode, an additional HD video resource is allocated.
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.
If the system cannot allocate the resource required for sending the
Content, the conference status changes to "Content Resource
Deficiency" and Content will not be sent to the legacy endpoints.
As the resource required for sending Content to legacy endpoints is
allocated on the fly, when scheduling a reservation, in rare occasions
when the MCU is fully loaded, "Resource deficiency" may be
encountered. This may prevent participants from connecting to the
conference or from Content being sent to the legacy endpoint. To
ensure resource for sending Content to legacy endpoints, add one
resource to the number of resources defined in the Reserve Resources
for Video Participants field, in the Conference Properties - General dialog
box.
• Non-H.239 (legacy) endpoints receive the Content via the video
channel using the same video protocol and resolution with which
they receive video.
• The highest Content resolution for legacy endpoints is:
