Abstract
In a method of furnishing output motion vectors (MV′), motion vectors (MV) are retrieved (DEC) from an encoded image signal (MPEG), and the retrieved motion vectors (MV) are post-processed to obtain the output motion vectors (MV′). The post-processing includes generating (CVG) candidate motion vectors, and selecting (CVS) the output motion vectors (MV′) in dependence upon the candidate motion vectors and the retrieved motion vectors (MV).

A method of furnishing output motion vectors, the method comprising the steps:
- retrieving motion vectors and a separate video signal from an input signal comprising an encoded image signal;
- and
- post-processing the retrieved motion vectors to form the output motion vectors,
- wherein the post-processing step includes the steps:
- generating candidate motion vectors independent of said retrieved motion vectors;
- and
- selecting said output motion vectors in dependence upon said candidate motion vectors and said retrieved motion vectors.
