Video Resolutions in AVC CP Conferencing

For a description of resolutions for SVC Conferencing Mode see Defining SVC Conference Profiles.

The RealPresence Collaboration Server always attempts to connect to endpoints at the highest line rate defined for the conference. If the connection cannot be established using the conference line rate, the Collaboration Server attempts to connect at the next highest line rate at its highest supported resolution.

Depending on the line rate, the Collaboration Server sends video at the best possible resolution supported by the endpoint regardless of the resolution received from the endpoint.

The video resolution is also defined by the Video Quality settings in the Profile.

●Motion, when selected, results in lower video resolution at higher frame rates (30 fps to 60 fps).

●Sharpness, when selected, results in higher video resolution at lower frame rate (30 fps and lower). However, it can also be sent in 1080p 60fps.

The combination of frame rate and resolution affects the number of video resources required on the MCU to support the call.

The following resolutions are supported:

Supported Resolutions

Resolution Name	Resolution in Pixels	Frames per Second	Symmetric/Asymmetric
CIF	352 x 288	30, 60	Symmetric
SD	720 x 576	30, 60	Symmetric
HD 720p	1280 x 720	30, 60	Symmetric
HD 1080p	1920 x 1080	30	Symmetric
HD 1080p	1920 x 1080	60	Symmetric in Motion,
			Asymmetric in Sharpness

Video Display with CIF, SD and HD Video Connections

Although any combination of CIF, SD and HD connections is supported in all CP conferences, the following rules apply:
