USING EXTERNAL COMPONENTS

Using GENLOCK Func- tions

This device features a GENLOCK IN terminal. Input external synchronization signals in the GENLOCK IN terminal to syn- chronize camera images or playback images with external signals.

Additionally, the H (horizontal) and SC (subcarrier) phase adjustments can be performed on image signals of this device for external synchronization signals from the GEN- LOCK menu screen.

GENLOCK functions are only valid in Camera mode. They do not work in VTR mode.

IEEE 1394

Connection

„During Standby or Stop mode, input synchronization sig- nals from a Sync signal generator to the GENLOCK/AUX IN terminal.

The following synchronization signals are applicable. SD synchronization signal: BB (Black burst) signals SMPTE170M (RS-170A)-compliant for NTSC ITU-R BT.470-6-compliant for PAL

HD synchronization signal: HDTV Tri-sync signals SMPTE296M-compliant for HD720p SMPTE274M-compliant for HD1080i

CAUTION

•When the FRAME RATE is set to 60/30 or 24 in the VIDEO FORMAT[1/2] menu screen, input a 59.94 Hz synchronization signal (vertical synchronization). 50 Hz/ 60 Hz synchronization signals cannot be synchronized.

If the FRAME RATE is set to 50/25, input a 50 Hz syn- chronization signal. 59.94 Hz/60 Hz synchronization sig- nals cannot be synchronized.

•Do not connect or disconnect the cable during recording or playback.

•When the power is turned on while the external synchro- nization signal is input, a vertical vibration occurs for a few seconds. This is not a malfunction.

•VTR playback signals with jitter cannot be synchronized with this device.

Setting

„Set this device to Camera mode.

„Set the GENLOCK/AUX IN switch to GENLOCK.

•When the camera image is locking to external synchro- nization signals, “SYNC LOCKING” is displayed on the screen. When locking to external synchronization sig- nals is complete, the indication disappears and you can enter recording mode.

Synchronized Signals

The synchronized signal differs depending on the input sync signal.

: Vertical phase

F : Field phase

 

Adjust SC PHASE and H PHASE in the above table from the GENLOCK menu screen.

Adjust SC and H PHASE

1.Display the GENLOCK menu screen.

Follow the steps in “Setting Menu Screens” on page 75 and proceed as follows. MENUrOTHERSrGENLOCK

2.In the GENLOCK menu screen, select the item to per- form phase adjustment for and adjust.

SD H PHASE : Adjust the H phase in SD analog signals. (During BB signal input)

HD H PHASE : Adjust the H phase in HD analog and SD/ HD SDI signals. (During Tri-sync signal input, PHASE of SD analog signals are simultaneously adjusted in HD H PHASE

item.)

SC PHASE : Adjust the SC phase in composite and YC signals.

For details, refer to “GENLOCK Menu Screen” on X See page 99.

MEMO

•H PHASE cannot be adjusted during playback or record- ing.

•IEEE1394 output stops while H PHASE is being adjusted.

•When values for SD H PHASE or HD H PHASE is changed, the images cannot be produced properly momentarily. This is not a malfunction.
