The following table describes the number of allocated video resources for each video resolution when using
the RTV protocol.
Allocated video resolutions per video resolution
Threshold HD Flag Settings using the RTV Video Protocol
The system flag MAX_ALLOWED_RTV_HD_FRAME_RATE defines the threshold Frame Rate (fps) in
which RTV Video Protocol initiates HD resolutions.
Flag values are as follows:
Default: 0 (fps) - Implements any Frame Rate based on Lync RTV Client capabilities
Range: 0-30 (fps)
For example, when the flag is set to 15 and the Lync RTV Client declares HD 720P at 10fps, because the
endpoint’s frame rate (fps) of 10 is less than flag setting of 15, then the endpoint’s video will open VGA and
not HD.
In another example, when the flag is set to a frame rate of 10 and the Lync RTV Client declares HD 720P
at 13fps, because the endpoint’s frame rate (fps) of 13 is greater than flag setting of 10, then the endpoint’s
video will open HD and not VGA
.
When the MAX_ALLOWED_RTV_HD_FRAME_RATE flag equals 0 (default value), Table 1-1 for the
MAX_RTV_RESOLUTION flag applies. When the MAX_ALLOWED_RTV_HD_FRAME_RATE flag
does not equal 0.
Selected Video Resolution Number of Allocated Video Resources
HD720p 3
VGA 1.5
CIF 1
QCIF 1
If the MAX_RTV_RESOLUTION flag is set to AUTO dual core systems always view VGA. For more
information on Lync RTV Client capabilities, see , Controlling Resource Allocations for Lync Clients
Using RTV Video Protocolfor more information.
Single core PC’s cannot view HD and always connect in VGA.
Dual Core Processor - The threshold for flag settings on Dual Core systems is 13 (fps) and less
for viewing HD. When system flag is set to 14 (fps) or higher, the RTV Video Protocol shall connect
in VGA.
Quad Core PC systems always view HD, even when flag settings are set anywhere from to 0-30.
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.
