Several implementations relate to 3D video (3DV) coding formats. One implementation encodes multiple pictures that describe different three-dimensional (3D) information for a given view at a given time. Syntax elements are generated that indicate, for the encoded multiple pictures, how the encoded picture fits into a structure that supports 3D processing. The structure defines content types for the multiple pictures. A bitstream is generated that includes the encoded multiple pictures and the syntax elements. The inclusion of the syntax elements provides, at a coded-bitstream level, indications of relationships between the encoded multiple pictures in the structure. The syntax elements also enable efficient inter-layer coding of the 3DV content, thereby reducing the bandwidth used to transmit the 3DV content. Corresponding decoding implementations are also provided. Extraction methods are also provided from extracting pictures of interest from such a 3DV multiple pictures and the syntax elements, the video stream characterized by such a 3D structure. |
