If the received video format does not correspond to 525 or 625 digital component
video standards as determined by the flywheel pixel and line counters, then one of
two schemes for determining the EDH calculation ranges will be employed:
1. Ranges will be based on the line and pixel ranges programmed by the host
2. In the absence of user-programmed calculation ranges, ranges will be
The registers available to the host interface for programming EDH calculation
ranges include active picture and full field line start and end positions for both
fields.
reset.
If any or all of these register values are zero, then the EDH CRC calculation ranges
will be determined from the flywheel generated H signal. The first active and full
field pixel will always be the first pixel after the SAV TRS code word. The last active
and full field pixel will always be the last pixel before the start of the EAV TRS code
words.
