Settings
Switch blanking on or off for individual lines in the vertical blanking interval. The
Y/C signal and odd/even fields are blanked simultaneously.

During playback of a tape on which a composite signal has been recorded, in the
playback circuit the edge subcarrier reducer (ESR) is automatically switched on
or off according to the VTR operation. When recording a "Non-Standard" signal,
for example, if the color edges are not as good as with a proper signal, the ESR
can be forced on. This item makes this selection.
AUTO : ESR is switched on and off automatically.
ON: ESR operation is forced on.
When the "Y-add"
a)
function is operative, when the playback signal is an odd field
and the reference signal is an even field, the playback signal is shifted by 1H (1
line) to suppress the vertical movement of the playback picture. This item selects
whether or not to apply a 1H shift to the vertical blanking interval.
ON : Carry out vertical blanking shift.
OFF: Do not carry out vertical blanking shift.
Note
If the 1H shift is applied during the vertical blanking interval, the signal recorded in
line 21 may intermittently appear in DT playback mode.
The "Y-add" function is normally switched on automatically during DT playback.
This item selects whether or not to force the "Y-add" function off.
AUTO : Automatically switch the "Y-add" function on.
OFF: Force the "Y-add" function off.
