Abstract
This disclosure describes an apparatus (106) for improving performance of a multipoint control unit (210). The apparatus (106) provides a video stream manipulator (208) and a multipoint control unit (210). The video stream manipulator (208) may encode one or more video streams in a predetermined video codec standard separately. Each of the encoded video streams includes at least one encoded video frame made of a plurality of macroblocks, where the macroblocks are segregated into a predetermined number of macroblock lines. The multipoint control unit (210) may assemble predetermined number of macroblock lines from each of the encoded video streams in a predetermined composition.
