Video scaler features
The versatile scaler provides variable horizontal and vertical
up- and down-scaling to randomly sized windows and has
independent brightness, contrast and saturation control for
scaled outputs.Vertical scaling offers linear phase interpolation;
6-bit phase accuracy and an accumulating filter for anti-aliasing.
Horizontal phase-correct up- and down-scaling means improved
signal quality of scaled data, especially for compression and video
conferencing applications.This scaling, at 6-bit phase accuracy
(1.2 ns step width), uses an anti-aliasing and accumulating filter.

• Horizontal and vertical scaling range: variable zoom to 1/64
