Information processing device and method

An information processing method, comprising:

• storing video components included in a 3D object video in a buffer corresponding to the video components on a basis of a component index;
• acquiring the video components from the buffer on a basis of the component index;
• and
• generating a display image using the acquired video components, wherein
• a plurality of the video components is simultaneously usable in one 3D object, and
• the component index is set to the video components included in the 3D object video in an extension for the 3D object video defined in a material layer of a scene description and has a different value for each of the video components.

An information processing device, comprising:

• processing circuitry configured to generate a scene description file;
• and
• set a component index to video components included in a 3D object video in an extension for the 3D object video defined in a material layer of the scene description file, the component index having a different value for each of the video components, wherein
• a plurality of the video components is simultaneously usable in one 3D object.
