Abstract

Official abstract text for this publication.

According to a picture coding method, a coded picture is stored, as a reference picture, into a storage unit; commands indicating correspondence between reference pictures and reference indices for designating reference pictures and coefficients used for generation of predictive images are generated; a reference picture being used when motion compensation is performed on a current block in a current picture to be coded is designated by a reference index; a predictive image is generated by performing linear prediction on a block being obtained by motion estimation within the designated reference picture, by use of a coefficient corresponding to the reference index; a coded image signal including a coded signal obtained by coding a prediction error being a difference between the current block in the current picture to be coded and the predictive image, the commands, the reference index and the coefficient is outputted.

First claim

Opening claim text (preview).

The invention claimed is: 1. A moving picture coding and decoding system which includes a moving picture coding apparatus which codes a moving picture and a moving picture decoding apparatus which decodes a coded moving picture, wherein said moving picture coding apparatus comprises: a command generation unit operable to generate commands indicating correspondence between reference pictures and reference indices designating the reference pictures; a maximum value determination…
