Patent ID: 8503804

Claim:
A decoding method for decoding a base stream generated by encoding a first image signal of a first view and a dependent stream generated by encoding a second image signal of a second view, the method comprising: detecting, on the basis of an access unit delimiter indicating a picture boundary between pictures in the base stream, the picture boundary in the base stream configured by inserting the access unit delimiter at the beginning of a picture in the base stream as a NAL unit including nal_unit_type; detecting, on the basis of a dependent delimiter indicating a picture boundary between pictures in the dependent stream, the picture boundary in the dependent stream configured by inserting the dependent delimiter at the beginning of a picture in the dependent stream, the dependent delimiter being a NAL unit including nal_unit_type with a value which is different from the nal_unit_type of the access unit delimiter; and decoding the base stream on the basis of the detected picture boundary in the base stream and decoding the dependent stream on the basis of the detected picture boundary in the dependent stream.
