ABSTRACT:
An image decoding method includes a first storage step of sequentially decoding pictures in a stream, storing a picture to be used as a reference into a picture memory, and managing the picture. Further, the image decoding method includes a determination step of determining whether or not random access reproduction has been designated, a state change step of changing a management state for managing a picture in the picture memory, when the random access reproduction has been designated, and a second storage step of sequentially decoding each of the coded pictures from a random access reproduction destination, storing, into the picture memory, a picture to be used as a reference, and managing the picture. This image decoding method enables the decoding of pictures with reference to an appropriate picture even when random access reproduction is performed.
