Field Field description
Received If enabled, the Cisco TelePresence
video: flow Server to requests that the endpoint or
control endpoint group send lower speed video
based on if the use of the video from that endpoint
viewed size does not require as high a speed as the
channel allows.
Video Selecting this check box allows the
transmit Cisco TelePresence Server to vary the
size resolution, or resolution and codec, of
optimization the video being sent to a remote
endpoint within the video channel
established to that endpoint.
Screen to The address of the endpoint that audio

Usage tips
Typically the Cisco TelePresence Server would
send a flow control message because of this
setting if the video from that endpoint was either
not being seen at all by other conference
participants or if it was being shown only in small
layout panes.
Select a setting from the drop-down list:
None: Do not allow video size to be changed
n
during transmission
Dynamic resolution only: Allow video size to be
n
optimized during transmission
Dynamic codec and resolution: Allow video size
n
to be optimized during transmission and/or
dynamic codec selection
With this option enabled, the Cisco TelePresence
Server can, for instance, decide to send CIF video
within a 4CIF channel if this will increase the
viewed video quality.
The circumstances under which decreasing the
video resolution can improve the video quality
include:
if the original size of the viewed video is smaller
n
than the outgoing channel
if the remote endpoint has used flow control
n
commands to reduce the bandwidth of the Cisco
TelePresence Server video transmission
Typically, lowering the resolution means that the
Cisco TelePresence Server can transmit video at a
higher frame-rate.
