Method and a decoder for decoding MPEG video

摘要

A decoded picture and parameters of a sequence layer, a GOP layer and a picture layer respectively for displaying the decoded picture are stored as a set in each of picture banks and parameter banks of a frame memory. Parameters of each layer stored as a set with a picture decoded immediately before are read out. Parameters attached to a picture to be decoded are decoded overwritten. Thus, the parameters of each layer stored as a set with the picture to be decoded are generated.
