    Abstract: PURPOSE: An image encoding method and a computer-readable recording medium are provided to use a super macro block for an intra-encoding process, thereby improving an encoding performance. CONSTITUTION: An image encoding device includes a motion predictor (910), a motion compensator (920), an intra-predictor (930), a coupler (940), a conversion encoder (950), a quantizer (960), and an entropy encoder (970). The intra-predictor receives a super macro block with a size of 16nx16n (n is a natural number over two), and implements intra-prediction on the super macro block. The coupler obtains a difference between a predicted block generated by the intra-predictor and the super macro block, and then generates a differential block.

    Abstract: PURPOSE: An intra prediction mode encoding/decoding method and an apparatus thereof are provided to derive a most probable mode (MPM) from a peripheral prediction unit during the encoding/decoding of an intra prediction mode, and perform alignment operation according to the presence of an MPM having the same prediction mode as the intra prediction mode of a current prediction unit among the derived MPMs, thereby reducing the computational complexity of an image encoder/decoder. CONSTITUTION: If there is an MPM having the same prediction mode as the intra prediction mode of a current prediction unit among MPMs derived from a peripheral prediction unit adjacent to the current prediction unit, an encoder and/or decoder encodes and/or decodes an index indicating which MPM is identical to the intra prediction mode of the current prediction unit (S1010~S1030). If not so, the encoder and/or decoder align the derived MPMs based on the mode value of the MPM. By using a residual intra prediction mode, the intra prediction mode of the current prediction unit is encoded and/or decoded (S1040,S1050).

    Abstract: PURPOSE: An encoding/decoding device and a method thereof for predicting an arbitrary motion vector are provided to consider a motion vector of a neighboring vector and a previous motion vector by scaling vector information of a motion vector of a neighboring vector and a previous motion vector.
