Video Protocol Select the video compression standard:
• Auto - Select this option to use the conference’s Video
Protocol settings and to enable the dynamic
adjustment of the Video Protocol. For more details, see
“Defining Advanced Media Settings” on page 4-57.
• H261 - the video compression standard mandatory to
all endpoints.
• H263 - a compression standard that provides improved
video quality. This standard is not supported by all
endpoints.
• H264 - a video compression standard that improves
video quality at a line rate lower than 384 Kbps.
• H264* - a Polycom proprietary standard for video
compression that improves video quality at a line rate
lower than 384 Kbps.
Note:
— When video protocol is set to Auto in the
Conference Properties – Settings, this overrides
the Video Protocol settings in the Participant
Properties – Advanced dialog box as the dynamic
mode is enabled and the video settings are forced
by the MCU.
— When Video Protocol is set to H.263 or H.264 and
the endpoint does not support it, the participant is
connected as Secondary (Audio only).
— During an On Going ISDN/ATM/MPI conference,
this setting may be disabled.
Recording Designate the participant as an audio recording port
connected to an external recording device:
Select one of the following:
• None – The participant is not connected to an external
recording device.
• Dial up – The participant is used as the recording port
to an external device.
