Panasonic P2HD VariCam AJ-HPX3700G Operating Instructions Manual page 70

As a result of processing to convert the video captured by
the imaging devices from a progressive signal to an interlace
signal, video signal delays will occur in the camera.
Since time is required for making the 2:3 pull-down from the
24P frame, there is a video signal delay in the camera.
When recording from a device that can record images
without a delay and the unit is connected in parallel, it is
necessary to synchronize the time code. To set this timing,
open the <TC/UB> screen from the MAIN OPERATION
page and set it in the TC VIDEO SYNCHRO item.
Set by referring to the connection example.

Remarks
For setting to correct the time code
according to the delay of video signals.
0: Do not correct.
1: To delay the time code to be
input according to the timing of
the video images.
2: To forward the time code to be
output according to the timing of
the video images.
3: To delay the time code to be
input and forward the time code
to be output, respectively,
according to the timing of the
video images.

Note
In the 1080/23.98PsF or 1080/24PsF mode, set the
23.98PsF or 24PsF HD signal as the reference signal and
input a 24 frame time code to the TC IN input.
If the VTR is capable of recording the HD SDI time code, it is
possible to receive the time code output from the HD SDI A ·
B output, and synchronously record video with the time
code. In this case, it is not necessary to supply a time code
output signal to the VTR.
Example 4:
When the unit and an external device are locked to the
external time code generator and when several units of
the camera are connected in a cascade configuration.
