3-2 Reference Signals for Video Output and Servo System
This section describes how reference signals for the
video output signals and servo system are selected.
The output from the internal reference video signal
generator is supplied to the output video signal and
servo circuits as a reference signal.
3-2-1 External Sync Signal for the Internal Reference Video Signal Generator
The internal reference video signal generator is
synchronized either to a reference video signal or to an
input video signal. Depending on the settings of the
OUT REF switch on the subsidiary control panel and
extended menu item 309, and the input signal
selection, the external synchronization status is as
shown in the following flowchart.
