Abstract:
A method and device to transcode H.264/AVC video frames into MPEG-2 can include converting the H.264/AVC interframe coding modes into modes allowed by MPEG-2 and converting H.264/AVC motion information into corresponding MPEG-2 semantics, and determining a most suitable motion vector for each MPEG-2 macro-block, on the basis of motion vectors of reference frames and sub-blocks of a H.264/AVC macro-block corresponding to the MPEG-2 macro-block.
