| 1. A transcoding system comprising:
decoding means for decoding a source encoded video stream to generate decoded video data, and for extracting past encoding
parameters corresponding to different generations of past encoding processes from said source encoded video stream;
encoding means for encoding said video data as a present encoding process to generate an encoded video stream; and
control means for receiving said past encoding parameters generated, and for controlling said present encoding process of
said encoding means based on said past encoding parameters.
