Enabling Video Switching

For the MCU to run Video Switching conferences the following criteria must be met:
•
The HD_THRESHOLD_BIT RATE flag is responsible for negotiation only,
It does not guarantee that the endpoint will open an HD channel or transmit on an opened HD
channel.

Creating a Video Switching Profile

A Video Switching enabled Profile must be created prior to running Video Switching
conferences.
Polycom, Inc.
Maximum Number of HD1080p Connections by Line Rate
RMX 1500
The display aspect ratio is 4x3 or 16x9.
Site names, skins, etc. are not supported in Video Switching.
Video forcing is enabled at the conference and participant levels.
Endpoints that do not support HD or are unable to meet these requirements connect as
Secondary (audio only).
The HD_THRESHOLD_BITRATE flag must be set in the System Configuration. The value
of this flag is the system minimum threshold bit rate.
The line rate selected in the conference Profile must be the same as or higher than that
specified by the HD_THRESHOLD_BITRATE flag.
The Video Switching option must be selected in the profile. For more information see
"Defining Profiles" on page 1-8.
The RMX must have available resources (ports).
The endpoints must support HD.
Click Setup>System Configuration.
The System Flags dialog box opens.
Set the HD_THRESHOLD_BITRATE flag to the required line rate value (range
384kbps to 4Mbs, default is 768kbps).
Click OK.
The MCU must be reset for flag changes to take effect.
For more information see "System Configuration" on page 19-4.
