Abstract
A transcoding method and apparatus and a motion vector interpolation method. The transcoding method and apparatus convert moving picture data from one encoding format to another encoding format. The transcoding method includes (a) decoding an image coded in a first encoding method and then obtaining encoding mode information and motion vector information of each block of the image; (b) selecting at least one of available encoding modes of a second encoding method based on the encoding mode information of each block of the decoded image; and (c) performing a motion estimation process on each block of the decoded image in the at least one selected encoding mode and then determining an optimal encoding mode for each block of the decoded image based on the motion estimation result(s).
