A stream based bitrate transcoder for MPEG bitstreams that utilizes information extracted from MPEG bitstreams, such as picture-type, coding complexity, motion vector and MB-mode. Using this information, a stream-based bitrate conversion of rhythm is realized. DCT coefficients are dropped with regard to two components, specifically, picture/MB-level classification and motion reference calculation.
