Abstract
A decoding method decodes 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 includes 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. Further, the method includes decoding the base stream and the dependent stream on the basis of the detected picture boundary in the dependent stream.

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 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 a nal_unit_type 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;
- and
- decoding the dependent stream on the basis of the detected picture boundary in the dependent stream.
A decoding apparatus 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 apparatus comprising:
- means for 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 a nal_unit_type 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;
- and
- means for decoding the dependent stream on the basis of the detected picture boundary in the dependent stream.
A decoding apparatus 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 apparatus comprising:
- a processing unit configured
- to detect, 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 a nal_unit_type 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, and
- to decode the dependent stream on the basis of the detected picture boundary in the dependent stream.
