Chapter 4 Using Time Data Note When the recording format of the tape is HDV, this setting is not available. Synchronizing the internal timecode generator to an external timecode - External synchronization External Regen mode You can synchronize the internal timecode generator of this unit to an external timecode which is either of the following. • LTC signal connected to the TC IN connector • VITC signal inserted in the video signal • Timecode signal embedded in the SD-SDI signal: LTC conforming to RP188 • Timecode signal embedded in the HD-SDI signal: LTC or VITC conforming to ARIB STD-B4.2.0 and RP188 Use this capability when synchronizing the timecode generators of multiple recorders, when recording the playback timecode of an external VCR, or when you want to record without breaking the relation of a source timecode and 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 non-drop-frame ) Proceed as follows. 1 Depending on the type of external timecode, set the signal input source and TIME CODE menu item (see page 79) as follows.

If SDI input is selected, the synchronization priority sequence of external timecode is as follows. 1 SD-SDI signal: RP188. HD-SDI signal: ARIB STD-B4.2.0, and RP188. 2 An input to the TC IN connector 3) HD-SDI input supports VITC as embedded timecode, and SD-SDI input supports VITC multiplexed into video signals. 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 80). 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. • Recording of VITC is supported only 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. 54 Recording Timecode and User Bit Data
