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.
Claims12
An encoding method for encoding a first image signal of a first view and a second image signal of a second view to generate a bit stream including a base stream and a dependent stream, the method comprising:
- encoding the first image signal to generate a base stream including at least one access unit delimiter indicating a boundary between access units of the bit stream, each access unit delimiter being included in a network abstraction layer (NAL) unit including a NAL type;
- and
- encoding the second image signal to generate a dependent stream including at least one dependent delimiter indicating a picture boundary between pictures in the dependent stream, each dependent delimiter being included in a NAL unit having a NAL type different than the NAL type included in a NAL unit including the access unit delimiter.
An encoding apparatus configured to encode a first image signal of a first view and a second image signal of a second view to generate a bit stream including a base stream and a dependent stream, the apparatus comprising:
- circuitry configured to
- encode the first image signal to generate a base stream including at least one access unit delimiter indicating a boundary between access units of the bit stream, each access unit delimiter being included in a network abstraction layer (NAL) unit including a NAL type;
- and
- encode the second image signal to generate a dependent stream including at least one dependent delimiter indicating a picture boundary between pictures in the dependent stream, each dependent delimiter being included in a NAL unit having a NAL type different than the NAL type included in a NAL unit including the access unit delimiter.
A non-transitory computer-readable storage medium storing computer-readable instructions thereon, which, when executed by a computer, cause the computer to perform an encoding method for encoding a first image signal of a first view and a second image signal of a second view to generate a bit stream including a base stream and a dependent stream, the method comprising:
- encoding the first image signal to generate a base stream including at least one access unit delimiter indicating a boundary between access units of the bit stream, each access unit delimiter being included in a network abstraction layer (NAL) unit including a NAL type;
- and
- encoding the second image signal to generate a dependent stream including at least one dependent delimiter indicating a picture boundary between pictures in the dependent stream, each dependent delimiter being included in a NAL unit having a NAL type different than the NAL type included in a NAL unit including the access unit delimiter.
