H.264 High Profile System Flags (<strong>Version</strong> 7.0.1 only)<br />

Chapter 2-Video Protocols and Resolution Configuration for CP Conferencing<br />

The flags listed below are used in version 7.0.1 only. From <strong>Version</strong> 7.0.2 these flags were replaced<br />

with the High Profile sliders in the Resolution Configuration dialog box. For more information, see<br />

"Controlling Resource Allocations for Lync Clients Using RTV Video Protocol” on page 2-26.<br />

Setting minimum bit rate thresholds that are lower than the default may affect the video<br />

quality of endpoints that do not support the H.264 High Profile.<br />

Endpoints that do not support H.264 High Profile will connect according to the minimum<br />

bitrate thresholds defined by the following System Flags:<br />

• H264_BASE_PROFILE_MIN_RATE_SD30_SHARPNESS<br />

• H264_BASE_PROFILE_MIN_RATE_HD720P30_SHARPNESS<br />

• H264_BASE_PROFILE_MIN_RATE_HD1080P30_SHARPNESS<br />

• H264_BASE_PROFILE_MIN_RATE_CIF60_MOTION<br />

• H264_BASE_PROFILE_MIN_RATE_SD60_MOTION<br />

• H264_BASE_PROFILE_MIN_RATE_HD720P60_MOTION<br />

These System Flags must be added to the System Configuration file before they can be<br />

modified. For more information see the "Modifying System Flags” on page 21-1.<br />

Example: If the High Profile Optimized option is selected in the Resolution Configuration dialog<br />

box and the System Flag values are set as in the following table:<br />

System Flag Default Value<br />

H264_BASE_PROFILE_MIN_RATE_SD30_SHARPNESS 256<br />

H264_BASE_PROFILE_MIN_RATE_HD720P30_SHARPNESS 1024<br />

H264_BASE_PROFILE_MIN_RATE_HD1080P30_SHARPNESS 1536<br />

H264_BASE_PROFILE_MIN_RATE_CIF60_MOTION 256<br />

H264_BASE_PROFILE_MIN_RATE_SD60_MOTION 1024<br />

H264_BASE_PROFILE_MIN_RATE_HD720P60_MOTION 1536<br />

Endpoints will connect at resolutions as set out in the following table, depending on<br />

whether they support H.264 High Profile or not:<br />
