Externally Locking the Time Code

The time code generator built into your AG-HPX370P/AG- HPX371E 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

GENLOCK IN

NOTE

In addition to an HD Y reference signal, a composite video signal can also be input as reference signal.

Input composite video signals when the system mode is 480i (576i) (SD) and 720P.

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 and recording cannot be normally performed, “TEMPORARY PAUSE IRREGULAR FRM SIG” blinks in red in the viewfinder and on the LCD screen and the current clip is divided. The continuity of the time code cannot be guaranteed. Recording resumes when the signal returns to normal. Recording

will not resume if interval, one-shot or loop recording is in progress.

Example 2: Connecting two or more AG-

 

HPX370P/AG-HPX371Es with

 

one another, with one being

4rding rfoRec

used as the reference device.

NOTE

Set the menu option TC VIDEO SYNCHRO to TC IN in the OUTPUT SEL screen and the menu option GL PHASE to COMPOSITE in the OTHER FUNCTIONS screen on both units.

Setting TC VIDEO SYNCHRO in the OUTPUT SEL screen to TC IN will supply the time code via TC IN to the next slave device without delay.

The subcarrier in the VBS signal of the VIDEO OUT connector of the camera cannot be externally locked.

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.
