Section 4— Switcher Operations
Still Image Storage
Video and key can be frozen either separately or simultaneously 
through the use of panel controls. In addition, the system has the 
ability to layer stills in a recursive manner. The system 
accomplishes this by sending the output of the frame store to the 
input of an M/E for combination with another image. A 
composite is generated that can be fed back to the input of the 
frame store and re-frozen.
