Synchronizing The Internal Timecode Generator To An External Timecode - External Synchronization - Sony HDV HVR-1500 Operating Instructions Manual

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 non-drop-frame )
Proceed as follows.

Depending on the type of external timecode, set the
signal input source and TIME CODE menu item (see
page 77) as follows.

2)SDI embedded TC only supports LTC. If SDI input is selected, the
synchronization priority sequence of external timecode is as follows.

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).
