Video Protocol Select the Video compression standard:
Auto - Select this option to use the conference’s
Video Protocol settings and enable the dynamic
adjustment of the Video Protocol in Video Switching
conferences.
H261 – The video compression standard mandatory
to all codecs.
H263 - A compression standard that provides
improved video quality at a line rate lower than 384
Kbps. This standard is not supported by all codecs.
H264 - By default, the Video Protocol is set to Auto.
When H.264 is selected as the Video Protocol, the
participants are “forced” to use the H.264 video
protocol. Endpoints that do not have H.264 video
protocol capabilities connect as Secondary.
Note:
• When the Video Protocol field in the Conference
Properties – Settings is set to Auto it overrides
the Video Protocol settings in the Participant
Properties – Advanced window as the dynamic
mode is enabled and the video settings are forced
by the MCU.
• If the Video Protocol is set to H.263 and the
endpoint does not support it, the participant will
be connected as Secondary (Audio only).
Auto Detect Select this option to enable the MCU to automatically
detect the line rate of incoming ISDN calls and
connect the participant accordingly, without prior
definition of the participant properties, such as Line
Rate. The participant can be connected at the
maximum line rate set for the conference. This option
is disabled for users using the MPI and ATM Interface
Types. When this option is selected, the following
parameters are automatically detected by the MCU
and therefore are disabled: Aggregation, Number of
Channels, Video Protocol, Audio Only, and Restrict.
