Synchronizing The Time Codes - Sony DSR-45 Service Manual

DSR-45/45P
• When this item is set to EXTERNAL, the INPUT
SELECT selector on the front panel is set to DV, and
no signal is input via the DV jack, or the software of
the editing controller does not output a time code, if
you start recording, bars (– –:– –:– –:– –) are
recorded as time code. At the point that the input of a
signal begins, the time code of that signal will be
recorded.
• When this item is set to EXTERNAL, if you input
time code to the DV jack that is not continuous or
does not advance correctly, the value of the recorded
or displayed time code may not be equal to the actual
value of the input one. If you use a tape with this
problem, you may not be able to perform search or
edit, depending on the devices you use.
To set the time code when the recording
starts
Set TC MAKE on the TC/UB SET menu to select the
time code to be recorded when recording starts.
REGEN: The time code value is set to continue the
time code from the time code already recorded on
the tape. If you start recording from a blank
portion of the tape, the time code starts from
00:00:00:00.
PRESET: The time code starts from the value set in
TC PRESET on the TC/UB SET menu.
To set the advancement mode
Set TC RUN on the TC/UB SET menu to switch the
advancement mode (counting up).
REC RUN: Time code advances only while
recording.
FREE RUN: Time code advances even when the
unit is not recording. This mode is used to set the
current time as the initial time code value, or to
synchronize the internal time code to an external
one.
Notes
• If you set the advancement mode to FREE RUN, the
time code will be updated by the internal clock while
the unit's power is off. The time code may have been
delayed or advanced somewhat if you turn on the unit
power again, play back a tape, or set the INPUT
SELECT selector to DV.
DSR-45/45P time codes
This unit has a DV jack. The time code output and
recorded on the tape differs as shown below when the
INPUT SELECT selector is set to DV and when it is set
to other than DV.

a) This includes stop, fast-forward or rewind. If the unit
cannot read the time code on the tape correctly, the
counter displays "– –:– –:– –:– –" and the time code is
not output from the TC OUT connector.
b) "DUB1", "DUP1" and "REC1" represent the state of the
unit when you press each of these buttons (AUDIO DUB,
DUP or REC) in the stop mode. If the counter displays
"– –:– –:– –:– –", the time code is not output from the TC
OUT connector when you press the AUDIO DUB button
in the stop mode.
• If the internal backup battery charge is exhausted, the
time code of the FREE RUN setting will be
initialized. The internal backup battery is fully
charged if you connect the power to the unit for about
8 hours. A fully charged internal battery can run for
about two weeks.
To set the frame mode (DSR-45 only)
Set TC FORMAT on the TC/UB SET menu to switch
the frame mode.
AUTO: Automatically sets the mode in accordance
with the loaded tape.
If nothing is recorded on the tape, the mode is set
to the non-drop frame mode. If the unit cannot
read the frame mode correctly from the tape, the
unit will use the mode that was set in the last
position it was able to read correctly on the tape. If
you remove the cassette, the mode of the last
position it was able to read correctly is cleared and
the mode is set to the non-drop frame mode. If TC
MAKE is set to PRESET, the mode is also set to
the non-drop frame mode.
DF: Selects the drop frame mode.
NDF: Selects the non-drop frame mode.
Note
In a DV format recording, the drop-frame mode is
used automatically.
To switch the time code output when
playing at various speeds (JOG)
Set JOG TC OUT on the TC/UB SET menu to control
the time code output from the TC OUT connector
when the tape is played at various speeds.
OFF: Does not output the time code.
ON: Outputs the time code.
Note
Continuous time code is output only when the tape is
played at normal speed. When the unit is in the jog or
search mode, discontinuous time code is output.

Notes on the Time Codes
Time codes output from the unit have the following
restrictions:
• The unit outputs an EE signal when it is in recording
or recording pause modes, or when you press the
REC button.
While the unit is outputing an EE signal, only the time
code from an external device that is connected to the TC
IN connector will be through-output from the TC OUT
connector when the INPUT SELECT selector is set to
other than DV, and TC/UB IN on the TC/UB SET
menu has been set to other than INTERNAL. (The time
code and user bits that are internally generated are not
output from the TC OUT connector.)
In this case, as a result, the time code will not be
output from the TC OUT connector when the time
code is not input from the external device connected
c)
to the TC IN connector.
You need to set TC/UB IN on the TC/UB SET menu to
INTERNAL to output a time code from the TC OUT
c)
connector even if no time code has been input from an
external device connected to the TC IN connector.
To set the unit to inherit a time code from the external
device even after you set TC/UB IN to INTERNAL
from some other setting, follow the steps below.
c)
1
Match the settings (used when TC/UB IN is set to
INTERNAL) of the unit with the external device
format. (See the setting example below.)
2
After setting TC/UB IN to other than
d) .
INTERNAL, connect the external device to the
TC IN connector to input the time code.
3
Set TC/UB IN on the TC/UB SET menu to
INTERNAL.
4
Disconnect the external device from the TC IN
connector.
Setting example
If the time code setting of the external device is

To synchronize the internal time code to
an external time code
1
Set the INPUT SELECT selector to other than DV.
2
Input an external time code (LTC) signal to the TC
IN connector of the unit.
3
Set TC/UB IN on the TC/UB SET menu to
DSR-45/45P (rear panel)
TC&UB EXT or TC EXT.
4
Set TC RUN on the TC/UB SET menu to FREE
RUN.
The internal time code generator locks onto the
external time code and starts advancing. Once the
internal time code generator has become
synchronized in this way, you can disconnect the
external time code input and this unit will maintain
the time code.
Notes
• This unit has a DV jack. The time code input/output
: Signal flow
with a DV connection is different from that with
other analog connections.
For details, see "DSR-45/45P time codes" on page 63
(GB).
• The time code output from this unit has some
restrictions.
For details, see "Notes on the Time Codes" on page 64
(GB).
To confirm external synchronization
Before you start recording, check that the internal time
code is synchronized with the external time code.
Press the STOP button to turn the unit to the stop
mode, then press the REC button.
Look at the time counter display and check that the
time code value displayed there matches the external
time code value.
• The internal time code is output with the phase
synchronized to the line-outs (COMPONENT OUT,
S VIDEO OUT, VIDEO OUT) when TC/UB IN on
the TC/UB SET menu is set to INTERNAL.
(When the EE signal is output, the output signals of
the line-outs are delayed for one line from the input
video signal when component video or S-video is
input, and delayed for two lines from the input video
signal when composite video (VIDEO IN REF.IN) is
input.)
• When inputting signals from the DV jack, if you set
DV IN TC to INTERNAL, the time code and user
bits generated internally are recorded under the
INTERNAL setting in TC/UB IN on the TC/UB SET
menu. If you want to record with the time code input
from the DV jack, set DV IN TC to EXTERNAL or
use the duplicate function.
• When REC MODE on the VTR SET menu is set to
DVCAM, if you set DV IN TC to EXTERNAL, this
unit records the time code input via the DV jack and
the user bits internally generated, and the TC OUT
connector outputs the same time code and user bits.
• During the duplicate operation, this unit records the
time code and user bits on the source tape currently
being duplicated and the TC OUT connector outputs
the same time code and user bits. The time code and
user bits are output with the phase synchronized to
the line-outs (COMPONENT OUT, S VIDEO OUT,
VIDEO OUT) during the duplicate operation.
For details on the duplicate function, see "Duplication
(generating a work tape with the same time code)" on
page 69 (GB).
• During the audio dubbing operation, the TC OUT
connector outputs the time code and user bits on the
tape currently being played.
For details on audio dubbing, see "Audio Dubbing" on
page 74 (GB).
• To display and check the time code currently being
advanced with the FREE RUN setting, press the REC
button when all the conditions below are met.
– The unit is in the stop mode.
– The COUNTER SELECT selector is set to TC.
– TC RUN on the TC/UB SET menu is set to FREE RUN.
– TC MAKE on the TC/UB SET menu is set to
Setting
PRESET.
FREE RUN
If you press the STOP button, the time code display
DF returns to the last time code value it was able to read
on the tape.
