9. TIME CODE OPERATION

The GY-DV550 records SMPTE-standard (U MODEL)/EBU-standard (E MODEL) time codes and user's bits. In the play or record mode, the reproduced time codes or user's bits are shown on the counter display. The LTC signal from the built-in time code generator is output through the TC OUT connector. In the play mode, the time code recorded on the tape is not output through the units connectors.

•Do not directly turn off the POWER switch in the record-pause mode; otherwise, time codes will not continue. Be absolutely sure to turn off the OPERATE switch beforehand.

Press the FF button in play mode to search the tape in the forward direction at about 10 times the normal speed.

•Press the REW button in play mode to search the tape in the reverse direction at about 10 times the normal speed.

Press the PLAY button to resume normal playback.

Press the STOP button to stop.

•The audio is reproduced during the search.

•Video noise may be observed or the image may become

unstable during the search, but this is not a malfunction.

Setting the time code related switches

•Set the TC GENE switch to REC or FREE.

REC : The data preset in the time code generator runs only during recording.

Use this setting if it is required to record continual time codes across different scenes.

*However, approximately ±1-frame variations may occur in scene transition accuracy.

FREE : The time code starts to run from the time it is preset in the time code generator.

Setting the VCR Setup Menu (U MODEL)

•Set the VCR Setup Menu item No. 516 DISPLAY SELECT to “TC”.

Select the time code generator's framing mode using the VCR
Setup Menu item No. 416 NON DROP/DROP.
DROP	: The time code generator's running method is set
	to the drop frame mode.
	Use this setting when placing emphasis on the
	recording time.
	The “DF” indicator lights up on the display in the
	drop-frame mode.

Drop frame/Non-drop frame mode (U MODEL)
In the NTSC system, the actual number of frames per 1
second is approximately 29.97 frames, but the number of
frames that becomes the processing reference of the time
code is 30 frames. To compensate for this difference, the
mode called drop mode drops frame 00 and 01 for every
minute that cannot be divided by 10.
The non-drop frame mode is when no frames are dropped
and the actual time shift is neglected.
Note:
When the VCR Setup Menu item No. 398 SSF MODE is set
to CUE MODE or MARK MODE, the time code generator’s
running method is internally set to the REGEN mode.
When this is the case and you want to enter the preset
mode, set the VCR Setup Menu item No. 398 SSF MODE
to “OFF”, or set the TC GENE switch to the REC or FREE
position again.
