Subject: BT848 adaptive AGC (fwd)

Can the BT848 driver enable the adaptive AGC mode?
In the BT848 hardware documentation
http://www.brooktree.com/pdf/graphics/DATASHTS/l848a_a.pdf
(page 106) describe how to enable the adaptive AGC.

Reason:
All the BT848 based video transmissions use a unnecessary high bandwith.
The automatic gain control (AGC) is to fast.
If a small part of the video change its brightness, the
whole video change it too.
The adaptive AGC could avoid this.

If possible, could you point my how to do it?
Other ideas?

Rgds,
Christoph Fleck
