More Information
Summary:Initially, forward prediction reference block data which has been read out from a reference frame memory and retrieval block data which has been read out from a retrieval frame memory are used to detect forward prediction motion vector and its residual by a forward prediction motion detecting circuit to preserve (store) them into a forward prediction motion vector/residual preservation memory. Then, backward prediction reference block data which has been read out from the reference frame memory and retrieval block data which has been read out from the retrieval frame memory are used to detect, by a backward prediction motion detecting circuit, backward prediction motion vector and its residual, and to read out motion vector and its residual which have been preserved (stored) in the forward prediction motion vector/residual preservation memory to carry out encoding by using these motion vectors in both directions.
