Abstract:
1. A moving picture encoding apparatus for encoding a moving picture by utilizing motion-compensated inter-frame prediction, comprising: a first encoding module for encoding the moving picture at a first frame rate and at a first image size, by performing at least motion compensation and DCT; a second encoding module for encoding the moving picture at a second frame rate and at a second image size, by extracting data after the motion compensation or DCT by said first encoding module; a motion vector calculation module for calculating a motion vector to be used by said second encoding module from a motion vector to be used by said first encoding module; and a prediction mode control module for controlling to make a prediction mode of said first encoding module be coincident with a prediction mode of said second encoding module, so that said motion vector calculated by said motion vector calculation module can be used by said second encoding module.
