Monitoring RTV
RTV information appears in all three panes of the Participant Properties - SDP tab.
Controlling Resource Allocations for Lync Clients Using RTV Video Protocol
The number of resources used by the system to connect a Lync client with RTV is
determined according to the conference line rate and the Maximum video resolution set in
the Conference Profile.
In versions 7.6 and earlier, when conferences are set to line rates above 600 kbps, the RMX
could allocate up to three video resources to Lync clients connecting using the RTV video
protocol.
From version 7.6.1, the system flag MAX_RTV_RESOLUTION enables you to override the
RMX resolution selection and limit it to a lower resolution. Resource usage can then be
minimized the 1 or 1.5 video resources per call instead of 3 resources, depending on the
selected resolution.
Possible flag values are: AUTO (default), QCIF, CIF, VGA or HD720.
For example, if the flag is set to VGA, conference line rate is 1024Kbps, and the Profile
Maximum Resolution is set to Auto, the system will limit the Lync RTV client to a resolution
of VGA instead of HD720p and will consume only 1.5 video resources instead of 3
resources.
When set to AUTO (default), the system uses the default resolution matrix based on the
conference line rate.
To change the default flag setting, add the MAX_RTV_RESOLUTION flag to the System
Configuration flags and set its value. For information, see the RMX 1500/2000/4000
