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.
L'invention concerne un circuit de démultiplexage séparant un descripteur de scène (SD), un descripteur d'objet (OD), et des trains de bits (ES), des décodeurs (207-1 à 207-n) permettant de décoder ledit train de bits. Les données de sortie d'un descripteur d'objet identique (OD) (constituant un objet identique) provenant des données de sortie desdits décodeurs, sont mélangées par un circuit mélangeur (261). Ces donnés mélangées sont ensuite transmises au circuit de synthétisation d'objet (272-i) d'un circuit de synthétisation (252) pourvu d'un point correspondant. Ce circuit de synthétisation d'objet (272-i) met en corrélation un objet avec une image et effectue un mappage de texture.
