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, based on an analysis of the image in a plurality of domains. An encoder section, generates the processed video signal and wherein, when the pattern of interest is detected, a higher quality, such as a higher bit allocation or higher computational processing, is assigned to the region than to portions of the at least one image outside the region.
