Abstract:
1. A media conversion device for relaying media communication between a plurality of communication terminal devices connected to a plurality of different networks, said media conversion device comprising: a server for discriminating communication media standards adopted by said communication terminal devices from control data controlling the media communication and supplied from said communication terminal devices, based on a call control protocol, to exercise call control for said communication terminal devices, said server including a first memory for storing the communication media standards and information used for communication; and a media converter, using the communication media standards thus discriminated, for converting in real-time media data supplied from said communication terminal devices into a signal of a relevant communication media standard, said media converter including wherein the received media data is processed in conformity with RTP (Real Time Protocol), wherein each of said plurality of communication terminal devices belongs to one of a plurality of communication terminal device groups, said information stored in said first memory including information on which of the plurality of groups to which one of said communication terminal devices belongs, and also including information specifying which of the communication media standards is adopted for the group to which said one communication terminal device belongs, said server being responsive to delivery of a control signal from said one to another of said communication terminal devices to discriminate which of the communication media standards is adopted by the other communication terminal device based on the control signal and the information stored in said first memory.
