• The Collaboration Server supports the VUI addition to the H.264 protocol for endpoints that
transmit wide video (16:9) in standard 4SIF resolution.
• When there is a change of speaker in a Continuous Presence conference, the transition is set by
default to fade in the current speaker while fading out the previous speaker.
To make this transition visually pleasant, fading in the current speaker while fading out the

The Fade In/Out feature can be disabled by adding FADE_IN_FADE_OUT as a new flag to the
System Configuration, and setting its value to NO.
