9.6.3 Noise Reduction and Noise Estimator
The noise reduction function is a sophisticated successor of the
noise reduction module from the PICNIC-chip, also known as
"LIMERIC".
Besides the noise reduction part, the Columbus noise
reduction module also comprises a noise estimator. This noise
estimator (the LORE-noise estimator) is a new design with the
ambition of more accuracy and with less control complexity
than the existing noise estimators.

Video: Scaler Part (Diagram B7, B8 and B9)
The Genesis gm1501 Scaler is a dual channel graphics and
video processing IC for LCD and plasma monitors and
televisions incorporating Picture in Picture, up to SXGA output
resolutions. The Scaler controls the display processing in an
LCD or plasma TV, e.g. like the deflection circuit in a CRT-
based TV. It controls all the view modes (e.g. like "zooming"
and "shifting"). Features like PC (VGA) or HD inputs, are also
handled by this part.
