Abstract

The present invention provides a picture coding apparatus which can reduce a load in decoding. When a RAU to be coded is an open GOP type RAU, the present invention includes: a motion estimation unit, a motion compensation unit, and the like which codes a picture to be coded to generate a BI-picture; a BI information generation unit which generates a RAU map indicating whether or not the BI-picture is positioned in a display order immediately before a starting I-picture in the RAU of the stream; and a variable length coding unit which writes the RAU map into the RAU of the stream.
