<p>In an image signal demultiplexing apparatus, a scene descriptor, object descriptors and respective bitstreams are separated by a demultiplexer circuit, and the respective bitstreams are decoded by decoders. Within output data from the decoders, output data associated with the same object descriptor (output data composing the same object) are mixed by a mixer circuit. Subsequently, the mixed output data is supplied to an object synthesizer circuit of a synthesizer circuit which is ;supplied with a corresponding node. Then, the object synthesizer circuit corresponds one image to one object to perform texture mapping. An image signal multiplexing apparatus multiplexes the scene descriptor, respective bitstreams, and information related to the bitstreams.</p> |
