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

Reference time

TC IN

code

 

 

 

 

 

Reference video

signal

GENLOCK IN

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

Reference video

signal

External time code TC IN generator

GENLOCK IN

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.

 

 

1

Turn on the POWER switch.

 

 

2

Position the TCG switch at F-RUN.

 

 

3

Set the COUNTER button to TC.

 

 

4

Supply a phase-relationship reference

 

time code (that conforms to the time code

 

requirements) and reference video signals

 

to the TC IN and GENLOCK IN connectors,

 

respectively.

•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.*1 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

*1 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.
