3-2 Reference Sync
Signals
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 Selecting Reference Sync
Signal Depending on Operational
Status
The reference sync signal selection switches automatically
between REF and INPUT depending on the menu settings
and the operating status of the unit, as shown in the
following table. a) EE: In E-E mode
PB: Playing back (normal playback, jog mode, shuttle mode, variable
speed mode and stop mode)
EDIT: Edit preset enabled
REC: Recording
• When there is no HDSDI signal input whereas INPUT is
selected, the unit synchronizes with the REF signal.
• When there is no REF signal input whereas REF is
selected, no external reference signal is used. In this
case, the unit synchronizes with the internally generated
reference signal.
3-2-2 Connecting Reference Signals
Connect reference signals as shown below, according to
the way in which the unit is to be used.
• Connections for recording from a switcher or
signal generator
