Endpoint Capability Information. Fields on this page will only be displayed if an
endpoint declares the specific capability. For example, if an endpoint does not
declare the VID H.CTX capability, the H.CTX field will not be displayed.
VID Provides information about the type of video and frame rate the
endpoint supports.
vfmt - does not display if the endpoint has no video capability. All
values are blank if there is an active call or this is an audio-only
endpoint. Otherwise, values for this field include:
■ FCIF for full CIF
■ QCIF for quarter CIF. Support of CIF implies support of QCIF. In
general, for larger screens, CIF displays sharper resolution video,
which ZCIF is blocked, but may run at higher frame rates and less
clear. The differences are less observable on very small displays.
■ cfps and qfps are the maximum frame rate (frames/second) at
which the endpoint can receive video for CIF and QCIF operating
modes. CIF frame rate values are 30fps, 15fps, 10fps, and 7.4fps.
If the endpoint does not support CIF (that is, the vfmt field is
QCIF), the cfps value should be blank.
■ da_sfg indicates support for H.261 Still Frame Graphics
transfers.
■ H.CTX, H.CTX+ and SG4 are proprietary video format
capabilities.
■ SG4_sfg indicates support for SG4 Still Frame Graphics
MISC The restrict field is 1 way for an endpoint to indicate that it is
operating at 56 kbps per channel, the other way is the 56/64
command mode with a value of restrict. An endpoint on a 56 kbps
conference must send one or both of the 2 indications that they are
operating at 56 kbps before they become a video source in a 56 kbps
conference. If they signal either way that they are operating at 56
kbps in a 64 kbps or 384 kbps conference, they are an audio-only
source, but the MCU continues to send Selected Communication
Mode (SCM) toward them when possible.
A MISC capability of derestrict and a 56/64 command of
derestrict together indicate that an endpoint is operating at 64
kbps. If either is restrict, the conference operates at 56 kbps.
Other field values include:
■ dcomp indicates support for WorldWorx PCS data compliance.
■ mbe indicates support for Multi Byte Extension. MBE capability is
used for the exchange of passwords, terminal names, and other
special capabilities, such as, support of WorldWorx PCS specific
features.
■ cic (Chair Indicate Capability) indicates chair control capability.
