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.

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.
