H.264 High Profile
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 reduce bandwidth requirements
for video data streams.
Video quality is maintained at bit rates that are 20% to 30% lower than previously
required. For example, a 832kbps 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.
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.
• 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 the RMX 1500/2000/4000 Administrator’s Guide, on page
"IP Participant Properties” on page 11-19.

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.

• H.264 High Profile is not supported:
— In MPM+ card Configuration Modes
— In Video Switched conferences
H.264 High-Profile should be used when all or most endpoints support it.
