ABSTRACT:
A composite decoding device for an MPEG-2 multichannel audio decoder. The composite decoding device is capable of simultaneously decoding information coded in a dynamic crosstalk coding manner and information coded in a phantom coding manner. To this end, the composite decoding device comprises an arithmetic unit for receiving a control word, information and a scale factor from a first-in-first-out memory, performing an arithmetic operation with respect to the received information and scale factor on the basis of a dynamic crosstalk coding manner or a phantom coding manner determined by the received control word and outputting the arithmetic result to a dual port memory, and a controller for generating a plurality of sequential control signals in response to the control word from the first-in-first-out memory to control the arithmetic unit.
