SD ACTIVE VIDEO EDGE CONTROL
Subaddress 0x82, Bit 7
The ADV739x is able to control fast rising and falling signals at
the start and end of active video to minimize ringing.
When the active video edge control feature is enabled
(Subaddress 0x82, Bit 7 = 1), the first three pixels and the last
three pixels of the active video on the luma channel are scaled
so that maximum transitions on these pixels are not possible.

At the start of active video, the first three pixels are multiplied
by 1/8, 1/2, and 7/8, respectively. Approaching the end of active
video, the last three pixels are multiplied by 7/8, 1/2, and 1/8,
respectively. All other active video pixels pass through unpro-
cessed.
