Video and Audio Signal Relations
MC-3.2 SMART CLOCK HD let’s you set the SD and HD video sync refer-
ence generators independently from each other. But both video genera-
tors are always frequency-locked to one common AES11, Grade 1, clock
basis, even when their frame rates are different.
When adjusting video frame rates of equal basis rates, the system auto-
matically phase-locks both video generators. Due to this, the vertical sync
patterns of the SD and HD video sync reference signal start exactly at the
same position.
Furthermore, MC-3.2 auto-detects integer relationsships between the
adjusted video standards and the basis audio clock rate (CLK
BASIS ). This
applies especially when 24fps or 25fps based video standards are selected
and the basis audio clock rate is set to 48.0kHz, 96.0kHz or 192.0kHz.
In that case, the AES/EBU and S/PDIF generators use the video frame to
lock the Z-preamble of the AES channel block start, aligned to AES11-
1997/2003 and EBU R83-1996.
This setting outputs a
1080 lines progressive
HD tri-level reference
signal with 29.97fps.
