Playback During Recording (HSR-2/2P only)
With the HSR-2/2P, you can play the latest recorded scene or a scene
recorded before without stopping recording now in progress. You can also
play a scene recorded on other cassettes. Fast-forward, rewind, time
search and alarm search operations are also possible during recording.
In playback during recording, pictures are recorded and stored on the hard
disk, and will be copied to the tape when Playback During Recording
mode is canceled.
Keys that can be used in Playback During Recording mode,
and their functions
When one of the keys below is pressed during recording (the REC
indicator is lit), Playback During Recording mode is activated, and the
operation using these keys is performed while recording is continued using
the hard disk.
PLAY (PRE REVERSE PLAY) key: To locate the preset point of the
pre-reverse time on the hard disk, before the current time. Playback
starts from that point. The pre-reverse time can be set on the PRE
REVERSE TIME SET display from the Function Control menu. Pre-
reverse playback is always directly from data on the hard disk. If
recording has not yet been made for the duration of the pre-reverse
time, playback starts from the recording starting point. This key
functions as the normal playback start key after a cassette operation.
TIME SEARCH and ALARM SEARCH keys: To execute a Time
search, Rec-end search or Alarm search operation.
EJECT key: To change the cassette.
F FWD and REW keys: To fast-forward or rewind a tape.
STOP key: To stop playback during recording. A guidance for the next
operation is displayed.
Note
Even when the REC indicator is lit, the unit will not be switched to
Playback During Recording mode by pressing the REW key at the tape
top.
If the optional SVRM-100A remote control unit is connected, you can
operate the HSR-2/2P using the keys on the SVRM-100A. The Jog/Shuttle
operation from the SVRM-100A is also possible.
Requirements for Playback During Recording
Recording cycle
In order to play back without stopping recording, the recording cycle must
be of a certain value or larger. The valid minimum value for the recording
cycle is displayed under the current REC CYCLE value on the setting
display for a Recording mode.
Even if the current set value is smaller than the valid minimum value, the
Playback During Recording operation will be enabled by setting
PRIORITY of the Function Control Menu to PLAY. In this case, the
recording cycle will be increased automatically to the same value as the
valid minimum value when Playback During Recording mode is activated.
(The recording cycle will return to the original value when Playback
During Recording mode is canceled.)

If the set value is smaller than the valid minimum value and REC is
selected for PRIORITY, a Playback During Recording operation cannot be
performed.
For details on the setting of the recording cycle, see “Setting the Recording
Modes” on page 5-12, and for the setting of PRIORITY, see “Function Control
Menu” on page 4-11.
Other requirements
• A Playback During Recording operation cannot be performed just after
recording has started. Activate Playback During Recording mode after
continuing recording for a certain period. For example, it is about 15
seconds with settings of 4 camera inputs, 0.4-second recording cycle, and
SUPER image quality.
• The message “NOT ORIGINAL” is not displayed during a Playback
During Recording operation.
• During a Playback During Recording operation, the camera name that
you have preset by menu operation is displayed. Therefore, the correct
camera name may not be displayed if a tape which is recorded in another
place is played back.
• The user data cannot be played back during a Playback During Recording
operation (when the RS-232C is used).
To play back the latest recorded scenes (Pre-reverse Playback)
1
Start recording as described in “Recording.”
2
Press the PLAY (PRE REVERSE PLAY) key.
Playback During Recording mode is activated. The point on the hard disc
just before the time set for PRE REVERSE TIME in the Function Control
Menu (1 to 99 minutes) is located, and playback starts. Recording is
continued using the recording buffer of the HDD.
For details on setting the pre-reverse time, see “Setting the Pre-Reverse Time” on
page 5-17.
Status display during a Playback During Recording operation
When Playback During Recording mode is activated, the display
“REC&PLAY**%” appears on the screen (“**” indicates the percentage
of remaining disk capacity available for recording).
As recording is made only on the hard disk in Playback During Recording,
the REC indicator on the front panel rapidly flashes.
Note
When a recording is made up to the maximum recording capacity of the
hard disk (“0%” is displayed) in Playback During Recording mode, data
are overwritten from the oldest. If the remaining disk capacity falls to 5%,
a beep will sound, and a caution message will be displayed.
The caution message will disappear when you press any key. In order to
avoid overwriting before the data on the hard disk are copied to a tape,
cancel Playback During Recording mode before the remaining capacity
falls to 0%.
