Format Conversion and Frame Sync
The switcher has four input format converter / frame 
synchronizer (FCFS) channels that can be used for

video format. The format converters can convert 
input video from many formats to the current 
switcher video format.
• Correcting mis-timed or drifting input signals in any 
of the supported video formats. The frame 
synchronizers can not completely correct badly 
formatted video streams, mis-timed switches, 
signal dropouts, or similar issues.
