12-3 DUBBING LOOP FUNCTION
12 EDITING SYSTEM PHASE ADJUSTMENT
The dubbing loop function allows you to effectively perform analog video signal adjustment.
The dubbing loop function loops video signals and generates color bar signals from the built-in signal generator.
The picture passes through the looped video signal circuit and is fed back and stored in the memory circuit. Then,
instead of outputting color bar signals from the signal generator, the picture stored in memory is output and
passed through the looped video signal circuit the designated number of times. The same effect is obtained each
time this pseudo-dubbing is repeated and the video signal can be adjusted according to the picture output.
