摘要： Provided is an apparatus for decoding a moving picture. An inverse quantization/transformation unit generates a quantized block by inversely scanning a quantized coefficient sequence, generates a transform unit by inversely quantizing the quantized block using a quantization step size, and generates a residual block by inversely transforming the transform block. An inter prediction unit generates a prediction block of a current prediction unit based on motion vector information. An adding unit generates a restored block using the residual block and the prediction block. When a motion information coding mode is a skip mode, the inter prediction unit restores motion information of the current prediction block using an available spatial or temporal skip candidate. The temporal skip candidate includes a reference picture index and a motion vector, the reference picture index of the temporal skip candidate is set to 0, and a motion vector of the temporal skip candidate is a motion vector of the temporal skip candidate in a temporal skip candidate picture. A size of the prediction unit is same with a size of a coding unit and the prediction block is set as the restored block.

摘要： Provided is a method that generates a prediction block of a current prediction unit, and generates a residual block of the current prediction unit. To generate the prediction block, a reference picture index and motion vector difference of the current prediction unit are obtained from a received bit stream, spatial and temporal motion vector candidates are derived to construct a motion vector candidate list. A motion vector predictor is selected and a motion vector of the current prediction unit is restored to generate the prediction block. Therefore, the motion vector encoded effectively using spatial and temporal candidates is correctly recovered and the complexity of a decoder is reduced.
