摘要： A decoding method generates a rectangular residual image by performing an inverse quantization and inverse frequency conversion processes based on coefficient data, a rectangular predicted image by reading a reference image based on motion vector data, and a decoded image by adding the residual image and the predicted image. The predicted images with respect to at least two or more rectangular regions are stored when generating the rectangular predicted image, and a predicted image ready signal notifies that the predicted image with respect to the at least two or more rectangular regions has been generated. The timings to store the coefficient data and the motion vector data are controlled in response to the predicted image ready signal.

摘要： In order to enable a rewrite of stored data to be omitted and to reduce a processing time of error concealment even if an error is detected in a process for sequentially storing variable-length data in a memory and the rewrite of the stored data is necessary, variable-length data from which an error is not detected is sequentially stored at and after a predetermined position in the memory, and error information that includes a restoration address that corresponds to an area in which variable-length data from which an error is detected is to be stored and that specifies variable-length data stored earliest in the memory from among data to be replaced with error concealment data is stored at a position preceding the predetermined position, when the error is detected.
