Using GENLOCK Func- tions

Synchronized Signals

The synchronized signal differs depending on the input sync signal.

Refer the table below.

Dubbing with AV Devices

VIDEO FORMAT menu screen

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.

By connecting the video signal output terminal and the AUDIO OUTPUT terminal on GY-HD250/GY-HD251 to an AV device, analog signal dubbing is possible.

1.Connect the cables.

To reduce the emission of unwanted radio waves, be sure to attach the provided clamp filter as shown in the figure below.

•Attach the clamp filter as close to this device as possi- ble, as shown in the figure.

• HDV PB OUTPUT item:

Set the video format to be output from the video output terminal during tape playback.

• PB TAPE item:

GENLOCK/AUX IN switch
GENLOCK/AUX IN terminal	-CH1 VIDEO
	CH2-AUDIOOUT
	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/

	V : 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.

Select whether to automatically detect the playback tape video format or play back only a particular format. Normally, use the “AUTO” setting.

• OUTPUT TERM. [DV] item:

Set component, RGB or Y/C signals for the output image signals of the [Y/PB/PR] terminal. (Only for DV format)

5.Set the audio output. X See page 63.

Set the AUDIO menu screen. X See page 87.

• PB AUDIO CH [DV] item:

Set the audio channel to be output.

6.Insert the videocassettes.

GY-HD250/GY-HD251 : Insert the recorded videocas-

sette.

Recording unit : Insert the videocassette to be dubbed to.

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.

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.

Clamp filter

2.Turn both devices on.

3.Set this device to VTR mode.

Press the CAM/VTR button. The VTR indicator lights.

4.Set the video output.

Set the VIDEO FORMAT menu screen. X See page 77.

7.Press the PLAY/STILL button on the GY-HD250/GY- HD251 to start playback.

8.Start recording on the recording unit.

For details, see the instructions to the unit used for recording.

9.When dubbing is completed.

Stop recording on the recording unit, and then press the STOP button on the GY-HD250/GY-HD251 to stop play- back.
