4.4.2 Video Tape Recorder Operation
The Video Tape Recorder mode of operation is useful for
display and analysis of pre-recorded activity. Recording is
continuously automatic, so there are no provisions for
"recording" an independent event, as with a standard VTR.
When a channel is set for display, the taped material is
transferred from a special buffer.
When a display on the MFSM has been selected and the
VTR pushbutton has been pressed, the VTR will then
function in a manner similar to normal analog devices. See
Section
3
for an explanation of pushbutton functions
associated with the VTR.
The display status indicates
"TAPE" when the VTR is active. To change the current tape
channel number, press either the
+
or· pushbutton.
The synch signal that is recorded with the original image is
automatically shown during playback. That signal is present
on the bottom part of the screen as numbers that correspond
to the minute and second of a one hour period. Shuttle
search is possible by pressing the
PLAY
pushbutton and
then pressing the
»
or «buttons. A speeded image of
the recorded material will be shown, along with synch
numbers at the bottom.
