<p>A system (102) for encoding a video stream into a processed video signal that includes at least one image, includes a region identification signal generator (150) for detecting a region of interest in the at least one image and generating (404) a region identification signal when the pattern of interest is detected. An encoder section (75) generates the processed video signal based on the operation of a plurality of encoding tools, each having at least one encoder quality parameter. The wherein encoder section (75) adjusts the at least one encoding quality parameter of at least one of the plurality of encoding tools in response to the region identification signal.</p> |
