Video encoding system with region detection and adaptive encoding tools and method for use therewith

摘要

A system for encoding a video stream into a processed video signal that includes at least one image, includes a region identification signal generator for detecting a region of interest in the at least one image and generating a region identification signal when the pattern of interest is detected. An encoder section generates the processed video signal based on the operation of a plurality of encoding tools, each having at least one encoder quality parameter. The encoder section 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.

1. A system for encoding a video stream into a processed video signal, the video stream including at least one image, the system comprising:
a region identification signal generator for detecting a region of interest in the at least one image and generating a region identification signal when the pattern of interest is detected; and an encoder section, coupled to the region identification signal generator, that generates the processed video signal based on the operation of a plurality of encoding tools, each having at least one encoding quality parameter, wherein the encoder section 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 and wherein the at least one encoding quality parameter includes a motion search range employed in motion search to determine a motion search motion vector, wherein the motion search range is adjusted in size within a region of interest to a first value only when the region identification signal indicates the pattern of interest is detected from a second value outside the region of interest.
