Enabling H.264 High Profile in VSW Conferences
‹ Select the H.264 High Profile check box, in the Profiles - General dialog box.
The High Profile check box is only displayed if MPMx cards are installed in the RMX. By
default the check box is not selected. If H.264 is not the selected video protocol the check
box is inactive (grayed out).
System Flags
Table 1-11 lists the System Flags that control the minimum threshold line rates for the various
resolutions available for High Profile-enabled VSW conferences.
Table 1-11 System Flags - Minimum Threshold Line Rates
Flag Name
Minimum Threshold Line
Rate (Kbps)
VSW_CIF_HP_THRESHOLD_BITRATE 64
VSW_SD_HP_THRESHOLD_BITRATE 128
VSW_HD720p30_HP_THRESHOLD_BITRATE 512
VSW_HD720p50-60_HP_THRESHOLD_BITRATE 832
VSW_HD1080p_HP_THRESHOLD_BITRATE 1024
• Line rate and resolution combinations are checked for validity. If the selected line rate is
below the minimum threshold line rate required for the selected resolution, the line rate is
automatically adjusted to the minimum threshold line rate value for the selected resolution.
• The value of the SUPPORT_HIGH_PROFILE System Flag (used for CP conferences)
has no effect on VSW conferences.
• Before they can be modified, all of the System Flags mentioned above must be added to
the system.cfg file using the RMX Menu – Setup option. For more information see
"Modifying System Flags” on page 21-1.
