PROBLEM TO BE SOLVED: To realize multiplexing/demultiplexing of other information data, even in a telephone system performing silent compression processing.;SOLUTION: An AMR processing section 10 multiplexes voice data, subjected to silent compression and information data different from the voice data. Silent compression data are produced by converting a silent data part, i.e. the voice data part in silent state, into a silent compression data part containing an SID frame indicative of silent state at a specified interval. An information data multiplexing section 18 detects the SID frame and inserts information data between the SID frames at the silent compression data part, based on the detection results.;COPYRIGHT: (C)2005,JPO&NCIPI
