Title: Method for decoding compressed video data with a reduced memory requirement

Abstract: For the purpose of bidirectional movement-compensated interpolation, it is proposed, when decoding compressed video sequences, completely to decode only one of the two reference frames. Only those respective picture areas of the other reference frame are decompressed which overlap with the picture area to be determined of the interpolated frame, taking account of a displacement corresponding to the movement compensation. As a result, a considerable reduction in the memory requirement of the decoding hardware is possible.
