<P>PROBLEM TO BE SOLVED: To provide a relay control apparatus, an inter-multi-point conference system, and an inter-multi-point conference method whereby each terminal can receive voice from the other terminals in a proper sound volume by means of ease of regulation and confirm the regulating state. <P>SOLUTION: DTMF signal extract instruction interpretation units 203-1 to 203-n provided in the relay control apparatus for relaying and controlling a plurality of terminals 102-1 to 102-n taking part in an inter-multi-point conference extract a DTMF signal from voice data transmitted from the terminals 102-1 to 102-n, interprets an instruction denoted by the extracted DTMF signal, mixers 204-1 to 204-n regulate the sound volume of the voice data from which the DTMF signal is extracted according to the interpreted instruction, and inform the terminals about the regulated state. Thus, the terminals 102-1 to 102-n can respectively regulate the sound volume of the voice data of its own terminal or the other terminals, and the terminals 102-1 to 102-n can confirm the regulated sound volume regulating state. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
