Abstract (en)
[origin: WO2006083107A1] A method of compressing a motion vector (MV) of a first macroblock when the region of a first lower layer corresponding to the first macroblock of a current layer frame does not have an MV is provided. The method includes interpolating the MV of a second macroblock to which the region belongs, based on the MV of at least one neighboring macroblock, and predicting the MV of the first macroblock using the interpolated MV.
