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.

9.7 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.
