JVC PROFESSIONAL, IMAGING PRODUCTS 23
Press the
MULTISCREEN
key. To select different cameras in a multi-screen, use active
cameo setup (see 3.1.2). This can be used, for example, to Play back cameras 4, 5, 11 and 14
in a quad display, which is at the best resolution for four cameras simultaneously.
During Play mode, the operator can select the multi-screen formats
that are available in Live
mode, except
for 7-way and 13-way displays.
Full-screen displays:
To select a camera for full-screen Playback on Monitor-A during the Play mode, push
the corresponding camera key once. A full-screen display of that camera from tape
will be displayed full-screen.
If tapes cannot be decoded:
If the
SW-D8000U, MULTIPLEXER
cannot decode a tape that is being Played back, the system
will display a blank screen. The fields will not be decoded or separated.
There are two possible reasons why a tape cannot be decoded:
q
The tape was not recorded on a multiplexer,
or
q
The tape is not compatible with the decoding format selected in programming.
In the event that the tape was actually recorded on either a
SW-D8000U
compatible multiplexer,
a Dedicated Micros, Robot or Calibur multiplexer, but is not correctly decoded, first check to see
that the correct
PLAYBACK FORMAT
has been selected in the menus. See the OPERATOR
MENU item in this manual.
To view tapes which were not decoded:
With the VCR Playback a tape, press
FUNCTION
then
PLAY
(see 3.6.4) to
view the undecoded input. It should be clear from the undecoded Playback
video if the video is multiplexed or not, as several camera images will be
overlaid on each other.
3.3.2
PLAY MODE: MONITOR-A INDICATIONS
During Playback, the on-screen text ‘
P
’ indicates the unit is in the Play mode.
The speed at which the data
was recorded
is displayed after the ‘
P
’ (e.g.
P002
or
P024
).
If the recording was made using the camera switch input (VEXT), then the mode and speed
indicator will read
‘P EXT’
. The time and date is displayed on-screen during Play mode.
NOTE:
This is the time recorded on the tape, not the current system time.
The indicator
‘V’
will be displayed in the corresponding camera cameo (
‘VDL’
if full screen), if
there was video loss at the time that the recording was made.
NOTE
:
Any camera which is not detected on tape for 8 or more consecutive cycles during
Playback, and is not flagged as a video loss camera, will result in the warning
message
‘N/A’,
signifying that it is
N
ot
A
vailable. This is only a warning, and can
appear during Playback on full-screen or multi-screen formats on Monitor-A.
Several circumstances can cause the
‘N/A’
indication:
q
The camera may not have been included in the record list at the time of recording.
q
The camera may have been disabled at the time of recording.
