20090097543 | PATTERN DETECTION MODULE WITH REGION DETECTION, VIDEO ENCODING SYSTEM AND METHOD FOR USE THEREWITH - 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. | 04-16-2009 |
20080212680 | METHOD AND SYSTEM FOR TRANSCODING VIDEO DATA - A first method of transcoding video data is disclosed that generates a motion vector for a macroblock encoded as a dual prime macro block that has a direct motion vector, and differential motion vector for its two fields respectively. Another method of transcoding includes replacing a skipped P-macroblock that has been used to backward predict a B-Frame with a P-macroblock having a motion vector of zero. Another method of transcoding includes replacing a skipped B-macroblock with a macroblock having a motion vector from a macroblock of the same frame of the skipped B-macroblock that is not co-located. | 09-04-2008 |
