∑Concerning the TC SYNC value and sync phase settings
Since the TC is similarly converted when the 1080/23psf (p) or 1080/24psf (p) format is converted into the
1080/59i (480/59i) or 1080/60i format, it is necessary to input the time information (TC SYNC value) that will
serve as the reference for conversion and the 3:2 pull-down sequence (sync phase) of the post-conversion
output images.
∑Setting the TC SYNC value
Input the pre-conversion TC with the frame count of 24 (24TC) and the post-conversion TC with the frame
count of 30 (30TC)/25 (25TC) to serve as the reference for conversion.
ONoteN
When converting from 1080/25psf to 1080/23psf to 1080/59i (480/59i), or from 1080/25psf to 1080/24psf
to 1080/60i
Input the pre-conversion 25-frame count TC (25TC) value that will serve as the reference during conversion
and the post-conversion 24/30-frame count TC (24TC)/(30TC) value. SYNC PHASE is valid during the 24TC
to 30TC conversion. When the audio insert editing status has been established by selecting ON as the setting for the F6
(RC_30SYS) key and 30TC for the F10 (RC_TC) key,  will appear at the top right of the HOME
menu and MANUAL EDIT menu, as shown below.

Audio insert editing function with 23.98 Hz VTR system and 30 Hz
external operating environments
As shown in the above diagram of the system connections, this function enables audio insert editing on the
23.98P tape of the model HD3700B even in an environment with a 30 Hz external device, and by so doing, the
efficiency of the editing work is improved.
Refer to the information provided later for details on the VTR menu settings.
OEditing accuracyN
With the model HD3700B, the IN/OUT point accuracy falls into one of the following three patterns since the
signals are recorded with the video and input audio phases aligned (there is no misalignment between the
audio and video phases) on the tape. (Bear in mind that, as shown in patterns 2 and 3, the IN and/or OUT
points may shift.)

Audio insert editing function with 23.98 Hz VTR system and 30 Hz
external operating environments
OPoints to noteN
The function will not work unless the following conditions are met.
(a) The system frequency of the VTR must be set to 23.98 Hz.
(b) The black burst reference signal must be connected.
(c) The settings below must be selected for the following items on the TC/CHR CONVERT menu:
RC_30SYS (F6) ON
RC_TC (F10) 30TC
(d) Use the AES input or analog input as the audio input signals, and make sure that embedded audio signals
are not selected.
(Otherwise, the signals may be edited with the audio and video phases misaligned.)
(e) The settings below must be selected for the following item on the INTERFACE SETUP menu:
VAR LIMT (F10) OFF
This function can be executed for audio insert editing only. Bear in mind that, in the status where the settings
above have been completed, the following editing modes are prohibited and cannot be set.
—Assemble editing mode
—Insert (video) editing mode
—Insert (CUE selection) editing mode
—Insert (TC selection) editing mode
Bear in mind that if, after the edit channel selection has been entered, one of the applicable prohibition condi-
tions has been established from an external source (9-pin or 232C connector) or by loading a user file or by
other means, the EDIT preset command or insert operation (video, CUE or TC) will be masked and executed.

LTC output selection when playing back a 25P (23.98P/24P) tape
with a 23.98/24 (25) Hz VTR system added
Since, as shown in the figure above, the video and audio signals are synchronized in the system in which a
tape recorded with a system frequency of 25 Hz is played back on a VTR with a system frequency of 23.98 (or
24) Hz, this function enables 25 Hz TC information to be supplied to an external DAT device for synchronized
operation with the VTR.
When a 1080/25P recorded tape is to be played back in this way on a VTR with a system frequency of 23.98
(or 24) Hz, the function makes it possible for the operator to select that the original 25-frame count TC record-
ed on the tape be output from the LTC_OUT connector in addition to the 24-frame count TC.
Conversely, when a 1080/23.98P or 1080/24P recorded tape is to be played back on a VTR with a system fre-
quency of 25 Hz, the function enables not only the 25-frame count TC but also the original 24-frame count TC
recorded on the tape to be output from the LTC_OUT connector.
[Bear in mind that, with the model AJ-HD3700H, audio signals will not be output properly when a 23.98P (or
24P) tape is played back on a VTR with a system frequency of 25 Hz.]
In short, the function expands the ability of systems to support the connection with and operation of external
devices, and it does this by making it possible for the original TC of pre-recorded tapes to be selected and out-
put from the LTC_OUT connector even when the system frequency of the VTR is at variance from the fre-
quency of the pre-recorded tapes in the manner explained above.
Refer to page 87 for the VTR menu setting items.
(Furthermore, the LTC waveforms which are output from the LTC_OUT connector using this function differ
from the waveforms defined in the specifications. This is because the tapes are played back at a different
speed from the speed at which they were recorded even when they are played back at the normal tape speed.)
