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.
