Abstract:
An image data decoding method for decoding compression encoded image data which includes a plurality of image pictures, includes: a selection step of selecting, when one of the plurality of image pictures are to be decoded, and when a first reference picture to be referred to by that image picture to be decoded is not decoded, a second reference picture from a picture already decoded as an alternative reference; and a decoding step of decoding the image picture to be decoded with reference to the second reference picture as an alternative to the first reference picture.
