Abstract: PROBLEM TO BE SOLVED: To provide a composite decoding device simultaneously processing information sets sent from an MPEG-2 multi-channel audio decoder through dynamic cross coding and virtual coding. SOLUTION: The composite decoding device for the multi-channel audio decoder is provided with an arithmetic section 11 receiving a control word, information and a scale index from a first-in first-out means FIFO, calculating information depending on the presence of dynamic cross coding and virtual coding decided by the control word and providing an output to a duplicate photo memory and with a control section 12 generating a sequential control signal with respect to the operation to be conducted by the arithmetic section 11 based on the control word received from the first-in first-out means FIFO.
