Phase lock for the HD reference signal
(23.98PsF) and 525 black burst signal
(59.94i mode)
When an optional HKDV-507D HD Pull Down Board
is installed and item A05. PD EXT SD REF LOCK
MODE  in the VTR SETUP menu is set to “lock1” or
“lock2” to lock the pull down output signal to the
external reference signal, the phase of the external
reference signals for 24F mode and 30F mode should
be locked as illustrated below.
Pull down output phase lock
When an optional HKDV-507D HD Pull Down Board
is installed and item A05. PD EXT SD REF LOCK
MODE  in the VTR SETUP menu is set to “lock2”,
the phase of the pull dowm otuput signal can be locked
as illustrated below.

Output delay
When an optional HKDV-507 HD Pull Down Board is
installed, or when an optional HKDV-507D HD Pull
Down Board is installed and item A05. PD EXT SD
REF LOCK MODE  in the VTR SETUP menu is set to
“off” or “lock1,” the phase of the output delay for
conversion is as illustrated below.
However, when the HKDV-507D board is installed
and item A05 is set to “lock1,” pull down output is
locked to the external reference signal (525 black burst
signal).
Pull down audio output
Audio signal multiplexed to the pull down HD SDI
output signal is delayed so that the audio signal and the
video signal are equal in phase as considering the
video signal delay due to video signal processing.  The
pulled down and down-converted SDI output signal is
also multiplexed with the delayed audio signal.
Note
The AES/EBU or analog audio output signal and 24-
frame video output signal (the main output line of this
unit) are equal in phase.
