RECORDING
In Record mode, single fields from up to 9 video input channels are assembled to form a continuous
multiplexed video signal, which can then be recorded on a VCR according to a pre-programmed
recording list.
Each recorded field is uniquely identified and linked to its input camera source by coded digital data
that is automatically inserted into the time-sliced video field. Time/date and camera status
information is also included in the coded data within each field. This coded data is used to provide
comprehensive status and camera identification information during later Playback of recorded
signals.
Record mode is always active. It is not necessary to press the RECORD key.
3.2.1
MONITOR OUTPUTS IN RECORD MODE
Monitor-A Output while recording:
The operator can select either the Live or Play mode while recording is taking place. The
operator can select any desired Monitor-A multi-screen function as previously described in
Section 3.0. In Play mode, images on Monitor-A are from the VCR tape recording when the
VCR is in Play mode. If the VCR is not in Play mode, then the images on Monitor-A are from the
VCR output of the
SW-D7000U
, not recorded images.
Record Speed Indicator on Monitor-A:
During recording, the
SW-D7000U
indicates the speed at which it is recording on Monitor-A. It
uses the same time-format for the indicator as is generally used by time lapse VCRs. For
example,
R024
will be displayed to indicate that the unit is
R
ecording in
24
hour mode. (If the
VCR VEXT input is active, then
R EXT
will be displayed.)
Monitor-B Output while recording:
Monitor-B always displays analog Live, full-screen images of the camera inputs, regardless of
which mode is selected.
3.2.2
ALARM DISPLAYS IN RECORD MODE
Alarm displays will conform to the Live or Play modes of operation. See Section 3.4 for further
details on alarms.
3.3
PLAYBACK
Play Mode:
To enter Play mode, press the
PLAY
key.
Play mode will initially always stop any Live mode multi-screen displays on Monitor-A. Monitor-B
always displays full-screen Live displays and hence will not be affected if Play mode is selected.
The
SW-D7000U
video multiplexer can display video Played back from a VCR whether it was
originally recorded from a multiplexer, or whether it was recorded from normal video input, (i.e. not
multiplexed).
