Externally Locking The Time Code - Panasonic P2HD AG-3DP1G Operating Instructions Manual

Externally Locking the Time Code

The time code generator built into your camera may be
locked to an external generator. It is also possible to lock
an external time code generator to the internal generator.
Connections for externally locking the
time code (examples)
As illustrated, both the reference video signals and the time
code must be input.
Example 1 : Locking the time code to
external signals
TCIN
Referencetime
code
Referencevideo
signal
GENLOCKIN
 NOTE
• Use an HD Y reference signal as reference video signal.
• During HD-Y signal input in 720P system mode, GENLOCK
input for the video signal is applied but the time code is
delayed by 1 field.
• If the reference GENLOCK input signal becomes irregular,
recording cannot be performed normally and the continuity
of the time code cannot be guaranteed. When the reference
GENLOCK input signal becomes irregular, the unit resets the
L/R section of the camera and is restarted.
(During this process, the image is disturbed.)
• The input signal of the RETURN IN connector can be locked
externally if the menu option GENLOCK SEL in the OTHER
FUNCTIONS screen is set to RETURN IN.
Example 2 : Locking the time code of this
unit and external equipment to
the time code from an external
time code generator
Referencevideo
signal
TCIN
Externaltimecode
generator
GENLOCKIN
 NOTE
When the system mode is 1080/23.98PsF, use the HD signal of
23.98PsF as a reference signal and input a 24-frame time code
to the TC IN connector.
To externally lock the time code
Follow the steps below.

• Now the built-in time code generator is locked to the
reference time code.
• When locked to an external time code generator, the
time code is at all times locked to the external time code,
which is displayed as a highlighted value on the counter
indicator. Do not engage the recording mode during the
few seconds it takes for the sync generator to stabilize.
• Once a slave relationship is established, the TC IN and
GENLOCK IN connectors stay in slave status.
Note that the following events release slave status.
• When TC PRESET is performed
• The power is turned off
• The time code mode is switched
• The TCG switch is set to R-RUN
• When REC FORMAT has been switched
The slave status locks the time code to the TC IN input

and the device will use this time code even if time
code input should subsequently cease.
Setting the user bits when the time code
is externally locked
To externally lock user bits, set the setting menu UB MODE
(RECORDING SETUP screen) to EXT.
Regardless of an F-RUN or R-RUN setting of the TCG
switch, the time code is slaved to user bit values input to
the TC IN connector.
For details, refer to [Setting Time Data] (page 59) and
[Setting User Bits] (page 61).
To unlock the externally locked time code
Discontinue external time code supply, then position the
TCG switch at R-RUN.
