Synchronizing the Internal Timecode Generator to an External Timecode
— External Synchronization
External regen mode
You can synchronize the internal LTC (Timecode signal connected to the TC IN connector, VITC signal inserted in the video signal, or RP188 LTC signal superimposed on SDI signal) generator to an external timecode (LTC) input to this unit. Use this method when synchronizing the timecode generators of multiple recorders, when recording the playback timecode of an external VCR, or when you want to record without interfering with the timecode relation of a source image.
Note
When an external timecode is input, the internal timecode generator advance mode and frame count mode are automatically set as follows.
Advance mode: FREE RUN
Frame count mode: same as the external timecode (drop- frame or
Proceed as follows.
1 Depending on the type of external timecode, set the signal input source and TIME CODE menu item (see page 77) as follows.

1)Select the video signal input with the INPUT SELECT buttons (see page 14) in the video/audio input selection section.
2)SDI embedded TC only supports LTC. If SDI input is selected, the synchronization priority sequence of external timecode is as follows.
1RP188 (embedded LTC)
2An Input to the TC IN connector
When the timecode generator is in the regenerate mode (when the setting of the TC MODE menu item is INT REGEN or EXT REGEN), you can select whether to regenerate both timecode and user bit data, or to regenerate either one of them, in the TIME CODE >TCG REGEN menu item (see page 78).
Notes
•When the input mode is i.LINK (the i.LINK indication appears in the video area of the input signal display), if you set the TC MODE menu item to EXT REGEN, then the internal timecode generator is synchronized to the i.LINK input and not to the TC IN input.
•External synchronization to VITC is only supported when the recording format of this unit is DVCAM.
•When the TC MODE menu item is set to EXT REGEN, and timecode is also input from an external device connected to the HDV/DV connector, if the input timecode includes discontinuities, or advances incorrectly, the input timecode and the timecode to be recorded on the tape may be out of step with the timecode display on this unit. Also, when using a recorded tape with timecode discontinuous in this way, editing and search operations may not perform correctly depending on the combination of equipment.
To check that an external synchronization is present
Press the STOP button to put this unit in stop mode, then press the REC button.
Watch the time counter display, and check that the value agrees with the external timecode value.
To record VITC
To record VITC on a tape, set the TIME CODE >VITC menu item to ON, and carry out recording (even if VITC is set to OFF, any VITC signal included in input video is recorded unchanged).
