polarity of AVI signal
0 = active video during AVI is high (if <17>AVINT = 0)
1 = active video during AVI is low (if <17>AVINT = 0)

0
polarity of AVO signal
0 = AVO is high active
1 = AVO is low active

delay from AVI (active video in) to AVO to compensate CIP 3250A
processing delays (if <17>AVINT = 0)
(0...63) + 14 – <22>AVPR clocks (if <10>DL1ON=0)

delay between AVO and YUV output
AVO preceedes YUV output by AVPR (0...3) clocks

AVO (active video out)
0 = derived from AVI (active video in)
1 = generated internally (see <23>AVHSTRT, <24>AVHLEN,
