Video Profile Parameters (continued)
Parameter
video.profile.H263.SqcifMpi
Specify the frame rate divider that the system uses when negotiating Sub Quarter CIF resolution for a video call. You
can enter a value between 0-32. To disable, enter '0'. The default frame rate divider is '1'.
video.profile.H2631998.annexF
Enable or disable Annex F when negotiating video calls.
video.profile.H2631998.annexI
Enable or disable Annex I when negotiating video calls.
video.profile.H2631998.annexJ
Enable or disable Annex J when negotiating video calls.
video.profile.H2631998.annexK
Specify the value of Annex K to use when negotiating video calls. You can enter a value between 0-4. To disable,
enter '0'. The default value is '1'.
video.profile.H2631998.annexN
Specify the value of Annex N to use when negotiating video calls. You can enter a value between 0-4. To disable,
enter '0'. The default value is '1'.
video.profile.H2631998.annexT
Enable or disable Annex T when negotiating video calls.
video.profile.H2631998.CifMpi
Specify the frame rate divider that the system uses when negotiating CIF resolution for a video call. You can enter a
value between 0-32. To disable, enter '0'. The default frame rate divider is '1'.
video.profile.H2631998.jitterBufferMax
The largest jitter buffer depth to be supported (in milliseconds). Jitter above this size always causes lost packets. This
parameter should be set to the smallest possible value that supports the expected network jitter.
video.profile.H2631998.jitterBufferMin
The smallest jitter buffer depth (in milliseconds) that must be achieved before play out begins for the first time. Once
this depth has been achieved initially, the depth may fall below this point and play out still continues. This parameter
should be set to the smallest possible value which is at least two packet payloads, and larger than the expected short
term average jitter.
video.profile.H2631998.jitterBufferShrink
The absolute minimum duration time (in milliseconds) of RTP packet Rx with no packet loss between jitter buffer size
shrinks. Use smaller values (33 ms) to minimize the delay on known good networks. Use larger values (1000ms) to
minimize packet loss on networks with large jitter (3000 ms).
