9-5 Reproducing Time Codes
 Set the VCR Setup Menu item No. 516 DISPLAY SELECT to
“TC”.
☞ See page 69.
 Set the counter display to indicate time code or user's bit
data.
 Reproducing time codes
Press the PLAY button.
• The “PB” indicator lights up on the display and the time
code or user’s bit data are indicated.
• When playing back sections where the time code is not
recorded, the time code progression stops.
The playback mode continues.
Time code more than two hours can not be displayed
correctly by consumer DV equipment, which has no
capability to display more than two hours.
The GY-DV700W also incorporates a time code reader. Therefore, when the unit enters record mode from record-pause mode, it
can read the time code data recorded on the tape and record time codes in continuation of the existing data. The recorded user's
bit data is identical to the user's bit data recorded on tape.
* However, approximately ±1-frame variations may occur in scene transition accuracy.
To enable this, set the time code related switches as follows before starting recording.
 • Set the VCR Setup Menu item No. 302 BACK SPACE to
“STANDARD”.
• Set the VCR Setup Menu item No. 516 DISPLAY SELECT
to “TC”.
☞ See page 69.
 Set the counter display to show time codes or user's bit data.
 Set the PRESET/REGEN switch to REGEN.
• The time code run mode becomes unrelated to the REC/
FREE switch settings.

9-3 Recording Time Codes by Slave-Locking the Built-in Time Code Generator with the External TCG
The built-in time code generator can be synchronized (slave-locked) with the EBU-standard LTC time code signal which is input
through the TC IN connector. Once the slave locking has been carried out, the built-in time code generator runs even when the
external time code input stops. Even when the power is switched off, it continues to run on the backup lithium battery.
1. Input the reference video signal into the external time code
generator and the SYNC IN connector of this unit.
2. Input the EBU standard LTC time code signal into the TC
IN connector.
3. Display time code on the counter display.
4. Set the switches in the TC GENERATOR block as follows.
• Set the PRESET/REGEN switch to “PRESET”.
• Set the REC/FREE switch to “FREE”.
* While the REC/FREE switch is set to “REC”, slave-locking
will not take place.
 Set the related VCR Setup Menus.
• Set the VCR Setup Menu item No. 398 SSF MODE to
“OFF”.
* If set to CUE mode or MARK mode, the slave-locking
will not take place.
• Set the VCR Setup Menu item No. 403 U-BIT SLAVE.
Set to “TC&UB” when the user’s bits should also be slave-
locked with the external time code generator.
5. Set and operate the external time code generator.
➡ The built-in time code generator is slave-locked with the
input external time code data.
The SLAVE indicator lights on the display.
* If the external time code generator phase is not genlocked
with the phase of the camera video signals, the “SLAVE”
display will flicker.
• Once slave locking has been made, the built-in time code
generator keeps on running even when the external time
code generator is stopped.
Note :
Do not connect or disconnect slaves during recording as
this may disturb the servo lock.
Note :
When the power is switched ON while external sync signal
is input, the screen moves in a vertical direction for a few
seconds. This is not a malfunction.
Multi-Camcorder Master-Slave Connection
When there is only one slave GY-DV700W, connect it as
indicated in the figure below.
When connecting several GY-DV700Ws as slaves, input the
REF video signal to SYNC IN connectors of all these units from
the sync signal generator.
