PROBLEM TO BE SOLVED: To provide a schema and style sheet for DIBR data. SOLUTION: A Bit Wrapper node schema used for compression of graphic data, and texture information having camera information and Depth used for Depth image base model rendering are provided. Ditexture is stipulated as an element, and includes an SF Depthtexture Node as a group node. The Bit Wrapper node schema represents graphic data including data to be compressed and has a node element which refers to an SF World node as a lower-order element, a Bit Wrapper Encoding Parameter element and three attributes whose names are type, url and buffer and whose types are SFInt 32, MFUrl and SFString. By this, the expression and compression of DIBR data can easily be adjusted in a stage at which 3D content is created by using a meta-expression method, and an input file conforming to a MPEG-4 coding device can easily be generated.
