Remote-control system including mobile radio-signal terminal

A mobile radio-signal terminal having a function of making radio-signal communication with another radio-signal terminal through a network, including:

• (a) a signal transmitter which transmits a first remote-control signal to a target device for remote-controlling said target device;
• (b) a signal receiver which receives a second remote-control signal indicative of a certain operation, from a terminal which remote-controls said target device;
• (c) a controller which obtains a remote-control code determined, based on said second remote-control signal having been received by said signal receiver;
• (d) a radio-signal transceiver which transmits said remote-control code to a data server through said network, and receives a set of remote-control codes used for remote-controlling said target device, from said data server through said network;
• and
• (e) a memory storing said set of remote-control codes having been received by said radio-signal transceiver,
• wherein said controller reads a remote-control code out of said memory for causing said target device to carry out a desired operation, transmits the thus read-out remote-control code to said signal transmitter, and causes said signal transmitter to produce said first remote-control signal.

A method of storing remote-control data used for remote-controlling a target device, comprising the steps of:

• (a) transmitting a remote-control signal to a mobile radio-signal terminal;
• (b) transmitting said remote-control signal from said mobile radio-signal terminal to a data server;
• (c) identifying a target device to be remote-controlled, based on said remote-control signal;
• (d) identifying remote-control data used for remote-controlling said target device, among a plurality of remote-control stored in said data server;
• (e) transmitting the thus identified remote-control data to said mobile radio-signal terminal;
• and
• (f) storing said remote-control data in a memory equipped in said mobile radio-signal terminal.

A program to be installed in a mobile radio-signal terminal for causing a controller to carry out a method of storing remote-control data used for remote-controlling a target device, steps executed by said controller in accordance with said program including:

• (a) receiving a remote-control signal from a remote-controller used for remote-controlling said target device;
• (b) transmitting said remote-control signal to a data server;
• (c) receiving remote-control data used for remote-controlling said target device which remote-control data has been identified among a plurality of remote-control stored in said data server;
• and
• (d) storing the thus received remote-control data in a memory equipped in said mobile radio-signal terminal.
