• Frame Rate: The frame rate is the number of frames per

second (fps) transmitted by the ViewStation to the far site.

This is adjustable to compensate for distorted video due to

high packet loss. Select the preferred video frame rate for

the broadcast transmission in frames per second or fps:

– 30 fps (Default)

– 15 fps

– 10 fps

– 7.5 fps

Set broadcast configuration parameters to accommodate the

lowest common denominator of the video communication

systems that receive the video and audio broadcasts. For

example, if one video communication system participating in

the video supports H.261 only, set the video protocol to

H.261 to ensure that all systems are able to participate.
