Field descriptions
VID Video and frame rate types that the end point supports.
“vfmt” = Does not d isplay if the endpoint has no video capabi lity. All
values are blank if an active c all or audio-only endp oint exists.
Otherwise, values for this field includ e:
■FCIF for full CIF
■QCIF for quarter CIF. CIF support implies QCIF sup port. For
larger screens, CIF typicall y displays sharper resolution vid eo,
ZCIF is blocked, but may run at higher frame rates with less
clarity. Differences are less observable on v ery small displays.
■cfps and qfps are maximum frame rates (frames/second ) that
the endpoint can rec eive video for CIF and QCIF operating
modes. CIF frame rate values are 30fps, 15fps, 10fp s, and 7.4fps.
If the endpoint does not s upport CIF (that is, the vfmt field is
QCIF), the cfps value should be blank.
■da_sfg indicates supp ort for H.261 Still Frame Graphics
transfers.
■H.CTX, H.CTX+ and SG4 are proprietary vid eo format
capabilities.
■SG4_sfg indicates supp ort for SG4 Still Frame Graphics
MISC The restrict field and the 56/64 co mmand mode with a
restrict value indicate that endp oints operate at 56 kbp s per
channel. Endpoints on 56 kb ps conferences must s end one or both 2
indications that they are op erating at 56 kbps b efore they become a
video source in a 56 kb ps conference. If they sig nal that they are
operating at 56 kbp s in a 64 kbps or 384 kbp s conference, they
become an audio-only source, but the MCU continues to send
Selected Communication Mod e (SCM) toward them when possible.
A MISC capability of derestrict and a 56/64 command of
derestrict together indicate that an end point operates at 64 kbp s.
If either is restrict, the conference operates at 56 kb ps. Other field
values include:
■dcomp indicates supp ort for WorldWorx PCS data compliance.
■mbe indicates supp ort for Multi Byte Extension. MBE exchanges
passwords, terminal names, and other special cap abilities, such
as, WorldWorx PCS specific features support.
■cic (Chair Indicate Capability) indicates chair control capability.
