Claim Text:
1. A video decoding apparatus for decoding a coded bitstream having both macroblocks encoded using block-matching motion compensation and macroblocks encoded using global-matching motion compensation, comprising: a macroblock motion vector storage for storing a macroblock motion vector received from the coded bitstream; a translation unit for generating a global motion vector from a global motion parameter received from the coded bitstream; a global macroblock motion vector storage for storing the global motion vector; an interpolation unit for generating a predicted image based on the macroblock motion vector and a decoded image when a current macroblock received from the coded bitstream is encoded using block-matching motion compensation, wherein the same interpolation unit is also used for generating another predicted image based on the global motion vector and the decoded image when the current macroblock received from the coded bitstream is encoded using global-matching motion compensation instead of using the global motion parameter received from the coded bitstream.
