Patent ID: 7469148

Claim:
A radio communication terminal device for use as a source terminal device in a radio communication terminal network with a tree structure in which a plurality of receiving side terminal devices on a downstream side of the source terminal device are connected to the source terminal device, each receiving side terminal device includes an upstream side control unit configured to make a connection for communication with an upstream side device and a downstream side control unit configured to make a connection for communication with a downstream side device, and other receiving side terminal devices on a further downstream side are connected to at least one of the plurality of the receiving side terminal devices and have the same functions as the receiving side terminal devices, the radio communication terminal device comprising: a speech input unit configured to input speeches; a speech coding unit configured to encode the speeches inputted by the speech input unit to generate contents data; a downstream side control unit configured to respond to a search from one downstream side device that requests the contents data among a plurality of downstream side devices or search the one downstream side device, and make a connection for communication with the one downstream side device; and a radio input/output control unit configured to transmit the contents data to the one downstream side device.
