  • Audio decoding device for decoding coded audio information with multiple channels
    Patent number: 6460016
    Abstract: An audio decoding device for decoding audio information with multiple channels includes a coded information memory section for storing the coded audio information; an information transmission section for reading the coded audio information stored at an arbitrary position in the coded information memory section; and an audio decoding section for decoding the coded audio information read by the information transmission section and outputting the resultant audio information in accordance with a time axis, wherein the information transmission section includes a buffer memory for retaining an address of an actual pointer for reading the coded audio information in the coded information memory section so as not to be reread, an address of a temporary pointer for reading the coded audio information in the coded information memory section so as to be reread, actual pointer data read by the actual pointer, and temporary pointer data read by the temporary pointer.
