SD ACTIVE VIDEO EDGE
[Subaddress 42h, Bit 7]
When the active video edge is enabled, the first three pixels and
the last three pixels of the active video on the luma channel are
scaled in such a way that maximum transitions on these pixels
are not possible. The scaling factors are

SAV/EAV Step Edge Control
The ADV7314 can control fast rising and falling signals at the
start and end of active video to minimize ringing.
An algorithm monitors SAV and EAV and governs when the
edges are too fast. The result will be reduced ringing at the start
and end of active video for fast transitions.
Subaddress 42h, Bit 7 = 1 enables this feature.
