SDA9410
5.4.3
The figure below shows a block diagram of the spatial and temporal motion adaptive
noise reduction (first order IIR filter). The spatial noise reduction is only performed on the
luminance signal. The structure of the temporal motion adaptive noise reduction is the
same for the luminance as for the chrominance signal.

5.4.3.1
Normally a spatial noise reduction reduces the resolution due to the low pass
characteristic of the used filter. Therefore the spatial noise reduction of the SDA 9410
works adaptive on the picture content. The low pas filter process is only executed on a
homogeneous area.
