Polycom RealPresence Collaboration Server (RMX) 1500/2000/4000 Administrator’s Guide

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:

•In a 1X1 Video Layout:

—SD: If the speaker transmits CIF, the MCU will send CIF to all participants, including the SD participants. In any other layout the MCU will transmit to each participant at the participant’s sending resolution.

—HD: The MCU transmits speaker resolution (including input from HD participants) at up to SD resolution. If 1x1 is the requested layout for the entire duration of the conference, set the conference to HD Video Switching mode.

•In asymmetrical Video Layouts:

—SD: A participant in the large frame that sends CIF is displayed in CIF.

—HD: Where participants’ video windows are different sizes, the RMX transmits HD and receives SD or lower resolutions.

•In panoramic Video Layouts:

—SD: Participants that send CIF also receive CIF.

—HD: the RMX transmits HD and receives SD or lower resolutions, the RMX scales images from SD to HD resolution.

H.264 High Profile Support in CP Conferences

The H.264 High Profile is a new addition to the H.264 video protocol suite. It uses the most efficient video data compression algorithms to even further reduce bandwidth requirements for video data streams.

Video quality is maintained at bit rates that are up to 50% lower than previously required. For example, a 512Kbps call will have the video quality of a 1Mbps HD call while a 1Mbps

HD call has higher video quality at the same (1Mbps) bit rate.

H.264 High-Profile should be used when all or most endpoints support it.

Guidelines

•H.264 High Profile is supported with MPMx cards only.

•H.264 High Profile is supported in H.323, SIP and ISDN networking environments.

•H.264 High Profile is supported in Continuous Presence conferences at all bit rates, video resolutions and layouts.

•H.264 High Profile is the first protocol declared by the RMX, to ensure that endpoints that support the protocol will connect using it.

Setting minimum bit rate thresholds that are lower than the default may affect the video quality of endpoints that do not support the H.264 High Profile.

•For monitoring purposes, the RMX and endpoint H.264 High Profile capability is listed in the Participant Properties - H.245 and SDP tabs for H.323 participants and SIP participants respectively.

For more information see "IP Participant Properties” on page 13-22.

•H.264 High Profile is not supported:

— In MPM and MPM+ card Configuration Modes
