Field descriptions
VID
Video and frame rate types that the endpoint supports.
“vfmt” = Does not display if the endpoint has no video capability. All
values are blank if an active call or audio-only endpoint exists.
Otherwise, values for this field include:
■
FCIF
for full CIF
■
QCIF
for quarter CIF. CIF support implies QCIF support. For larger
screens, CIF typically displays sharper resolution video, ZCIF is
blocked, but may run at higher frame rates with less clarity.
Differences are less observable on very small displays.
■
cfps
and
qfps
are maximum frame rates (frames/second) that
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 and the
56/64
command mode with a
restrict
value indicate that endpoints operate at 56 kbps per
channel. Endpoints on 56 kbps conferences must send one or both 2
indications that they are operating at 56 kbps before they become a
video source in a 56 kbps conference. If they signal that they are
operating at 56 kbps in a 64 kbps or 384 kbps conference, they
become 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 operates 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 exchanges
passwords, terminal names, and other special capabilities, such
as, WorldWorx PCS specific features support.
■
cic
(Chair Indicate Capability) indicates chair control capability.
