Abstract:
A PCM data outputting method of receiving input of a data stream of PCM packets to output PCM data, comprising the steps of:receiving input of a PCM data stream made up of a plurality of packets in which PCM groups each composed of a plurality of PCM data follow one after another and in which a header of a packet to which PCM data at the head of each PCM group belongs contains PCM group information of the PCM group in question and providing packet synchronization with respect to the PCM data stream to output PCM data by a predetermined number of the plurality of data, as well as outputting PCM group information from said header; writing said PCM data into a PCM buffer; generating an address in said PCM buffer at which PCM data at the head of said PCM group is written; and based on said address, reading PCM data from said PCM buffer and externally outputting the data together with said PCM group information.
