When communicating with an endpoint, the
MCU receives a list of supported video codecs
from the endpoint. The MCU chooses a video
codec from those available, and sends video data
to the endpoint in that format.

When enabled, the MCU will upscale video
streams from participants who are sending low
resolution video with the purpose of making best
use of the MCU's HD video capabilities.

The MCU uses intelligent resolution upscaling
technology to improve the clarity of low-
resolution video. Check this setting to enable it
to do so.

Allows the MCU to vary the resolution and codec
of the video being sent to a remote endpoint
within the video channel established to that
endpoint. The options are:
of the video being sent to a remote endpoint
within the video channel established to that

: Do not allow video size to be
changed during transmission
: Allow video
size to be optimized during transmission

With this option enabled, the MCU 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:
video resolution can improve the video quality
include:
if the original size of the viewed video is
smaller than the outgoing channel
smaller than the outgoing channel
if the remote endpoint has used flow
control commands to reduce the
bandwidth of the MCU video
transmission

Typically, lowering the resolution means that the
MCU can transmit video at a higher frame-rate.

This setting can be used to influence the choice of
outgoing video resolution made by the MCU in
certain circumstances.

The MCU will use its normal internal
algorithms to dynamically decide which
resolution to send in order to maximize
the received video quality.
