Abstract

A method and system for an efficient transcoding of a sequence of input images in a first format to a sequence of output images in a second format are described. The method utilizes the encoding block mode, the motion vectors and the residual information extracted during the decoding of the input image that are effectively reused to select an optimal transcoding block mode and to perform selective refinement of motion vectors. A corresponding system for video transcoding is also provided.
