Processing multiview video is provided to enable more efficient coding rather than the coding that is performed based on the division of an interview group and a non-interview picture group. A decoding apparatus includes a parsing unit(10), an entropy decoding unit(11), an inverse quantization/inverse transform unit(12), an inter-prediction unit(13), an intra-prediction unit(14), a deblocking filter(15), and a decoded-picture buffer(16). The inter-prediction unit performs the inter- prediction using the reference pictures stored in the decoded picture buffer. The inter-coded macroblock may be divided into macroblock partitions. Each macroblock partition can be predicted by one or two reference pictures. A motion compensation unit(17) compensates for a motion of the current block using the information received from the entropy decoding unit. The motion compensation unit extracts motion vectors of neighboring blocks of the current block from the video signal, and obtains a motion-vector predictor of the current block. The motion compensation unit compensates for the motion of the current block using a difference value between the motion vector and a predictor extracted from the video signal and the obtained motion-vector predictor. |
