The present invention relates to an encoding device and an encoding method, as well as a decoding device and a decoding method, configured to allow a multi-viewpoint image to be encoded and decoded using a format compatible with an existing format. A compatibility encoder encodes a compatible image (A1) in increments of access units and generates a compatible stream. An auxiliary encoder encodes, in increments of access units, the result of multiplexing auxiliary images (B1, C1) used when a multi-viewpoint image is generated from the compatible image, and generates an encoded stream of the multiplexed auxiliary images. A multiplexing unit transmits the compatible stream, a 3DV representation delimiter showing unit boundaries, and the encoded stream of the multiplexed auxiliary images. This technique can be applied to, e.g., an encoding device for encoding a multi-viewpoint 3D image. |
