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. 

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 Protocol” on page

 for 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. For more information, see  "Microsoft RTV Video Protocol Support in CP Conferences”
