Format
(in/out)
The video format for single-screen conferences:
CIF
,
QCIF,
QCIF/CIF, H.CTS, H.CTX+
, and
SG4
.
non-H.261 conferences = input and output formats are always
symmetric and the mode is the same for input and output.
(H.CTX, H.CTX+, and SG4).
H.261 mode non-continuous presence conferences = symmetric
format (CIF and QCIF).
Non-presentation, continuous presence conference in
single-screen = symmetric format (CIF and QCIF).
Presentation mode H.261 single screen continuous presence
capable conferences = symmetric input and output formats
QCIF/CIF (displayed as CIF) or asymmetric QCIF/CIF, if the
administered format is upgradeable.
For quad-screen conferences = the format is QCIF/CIF to reflect
the QCIF input from all participants and output of CIF to all
participants.
For presentation mode quad-screen conference = the format is
QCIF/CIF to reflect the input/output of all participants except the
presenter. In quad-screen mode, presenter input is always CIF.
FPS
The CIF frame rate (frames per second) -
‘-‘, 30
,
15
,
10
,
7.5
. FPS indicates the rate that endpoints can receive frames.
The MCU cannot detect maximum transmit frame rates or
current frame rates. Frame rates change due to the amount of
motion in the input image.
QFPS
The ACIF frame rate (frames per second) (‘
-
‘,
30
,
15
,
10
,
7.5)
. The rate that an endpoint can generate/receive frames.
Quad-screen VAS conferences = QFPS reflects the highest
common QCIF frame rate of all endpoints and the video mixer
board rate, that is lower than the rest of the participants. QCIF
calculation accounts for the highest common CIF frame rate
declared by all conference participants, since the QCIF rate
cannot be greater than that of the highest common CIF rate.
Quad-screen presentation conferences = QFPS reflects the
highest common QCIF frame rate of all participants and the
video mixer board rate. QFPS cannot be greater than the CIF
frame rate that is announced by the presenter.
QFPS field is
blank
for proprietary modes.
lo/hi
interworking
Does this conference support Low Speed/High Speed
Interworking? This field defaults to
n
.
Type
The type of conferee — Audio/Video (
P64
), Audio Add-on (
AUD
),
Cascade Link (
CAS
), BONDing Call (
BOND
), BONDing Cascade
Link (
BCAS
), UCC Controller (
UCC
), or Dedicated Access (
DA
).
BONDing calls use up to 12 channels to form a single
multimedia pipe.
Ext
Administered endpoint extension. ().
