The present invention relates to an image signal decoding apparatus, an image signal decoding method, an image signal encoding apparatus, an image signal encoding method, and a program that allow easy detection of picture boundaries of a Dependent stream on a bit stream. On a bit stream, an AD (AU Delimiter) is placed at the start position of each AU (Access Unite), and a DD (Dependent Delimiter) is placed at a picture boundary of a Dependent stream. The beginning of a NAL unit is detected by detecting a start code, and a DD, that is, a picture boundary (beginning) of the Dependent stream, is detected by checking if the nal_unit_type value whose beginning has been detected is 18. The present invention can be applied to an apparatus that processes a stereoscopic image signal. |
