Abstract
A system for encoding a video stream into a processed video signal that includes at least one image, includes a pattern detection module for detecting a pattern of interest in the at least one image and identifying a region that contains the pattern of interest when the pattern of interest is detected. An encoder section, generates the processed video signal and wherein, when the pattern of interest is detected, a higher quantization is assigned to the region than to portions of the at least one image outside the region.
