PICTURE CODING APPARATUS AND PICTURE DECODING APPARATUS

摘要

PICTURE CODING APPARATUS AND PICTURE DECODING APPARATUS ABSTRACT The present invention provides a picture coding apparatus which can reduce ~ load in decoding. When a RAU to be coded is an open Gap type RAU, the present invention includes: a motion estimation unit (401), a motion compensation unit (402), and the like which codes a picture to be coded to generate a BI-picture; a BI information generation unit (413) which generates a RAU map (MIa) indicating whether or not the BI- picture is positioned in a display order immediately before a starting 1- picture in the RAU of the stream (STR); and a variable length coding unit (411) which writes the RAU map (MIa) into the RAU of the stream (STR).
