ABSTRACT:
Transcoder apparatus for transcoding an input video bit-stream having a first encoding profile (e.g., MPEG-2) into an output video bit-stream having a second encoding profile (e.g., H.264), the first encoding profile including motion estimation information, the apparatus including: a front-end for extracting the motion estimation information from the input video bit-stream, and a back-end for constructing the output bit-stream. The front-end and the back-end of the apparatus are interconnected (e.g., via a buffer) to pass the motion estimation information from the front-end to the back-end, thereby avoiding motion estimation in constructing the output bit-stream at the apparatus back-end.
