Abstract

In a remote control system according to the present invention, a plurality of receivers are arranged for a network. Each receiver has an unique ID number. A control unit controls an operation of each receiver through the network. An input unit uses the unique ID number in each receiver for registration in the control unit. Thus, the control unit individually manages (controls) each receiver through the network. Thus, a plurality of receivers of the same type can be individually managed.

Claims

1. A remote control system comprising:

a plurality of receivers each supplied with an unique identification number;

a control unit remotely controlling each of said plurality of receivers through a network; and

an input unit inputting said identification number of each of said plurality of receivers;

wherein

said control unit includes;

a first memory storing said identification number input from said input unit,

an operation control circuit issuing a command for making selected said receiver execute a specific operation with said identification number stored in said first memory, and

a transmission circuit for transmitting said command to said network; and

each of said plurality of receivers includes a second memory storing said identification number, a receiving circuit for receiving said command from said network and a circuit recognizing said command, and executes said specific operation when said identification number included in said command matches with said identification number stored in said second memory.

2. The remote control system in accordance with claim 1, wherein

said second memory includes a nonvolatile memory.

3. The remote control system in accordance with claim 2, wherein

said identification number is printed on a case of each of said plurality of receivers,

said input unit includes a keyboard, and

a user inputs said identification number printed on said case from said keyboard.

4. The remote control system in accordance with claim 2, wherein

said identification number is printed on a case of each of said plurality of receivers, and

said input unit includes an image scanner unit recognizing and capturing said identification number printed on said case.

5. The remote control system in accordance with claim 2, wherein

said identification number is printed on a case of each of said plurality of receivers in the form of a bar code, and

said input unit includes a bar code reader capturing said bar code printed on said case.

6. The remote control system in accordance with claim 2, wherein

said identification number is printed on a case of each of said plurality of receivers,

said input unit includes a personal computer including a keyboard and a display supporting input through said keyboard, and

a user inputs said identification number printed on said case from said keyboard.

7. A remote control system comprising:

a plurality of receivers each supplied with an unique identification number; and

a control unit issuing a command and remotely controlling each of said plurality of receivers through a network on the basis of said command, wherein

each of said plurality of receivers includes;

a first memory storing said identification number, and

a first transmission/receiving circuit transmitting said identification number read from said first memory to said network and receiving said command from said network,

said control unit includes;

a second transmission/receiving circuit receiving said identification number from said network and transmitting said command to said network,

a second memory storing said received identification number, and

an operation control circuit issuing said command for making selected said receiver execute a specific operation with said identification number stored in said second memory, and

each of said plurality of receivers executes said specific operation when said identification number included in said command matches with said identification number stored in said first memory.

8. The remote control system in accordance with claim 7, wherein

said first memory includes a nonvolatile memory.

9. The remote control system in accordance with claim 8, wherein

said network includes:

a first network transmitting said identification number, and

a second network transmitting said command,

said first transmission/receiving circuit includes;

a first transmission circuit corresponding to said first network, and

a first receiving circuit corresponding to said second network, and

said second transmission/receiving circuit includes;

a second receiving circuit corresponding to said first network, and

a second transmission circuit corresponding to said second network.

10. A receiver used in a remote control system, said receiver connected to a network and an electrical apparatus and receiving a command from a control unit via said network to make said electrical apparatus execute an operation according to said command, comprising:

a nonvolatile memory storing an identification number unique to said receiver;

an interface circuit receiving said command from said network; and

an operation circuit comparing an identification number included in said command received by said interface circuit with the unique identification number stored in said nonvolatile memory for making said electrical apparatus execute an operation according to said command if the identification numbers match with each other,

said unique identification number having been stored already in said nonvolatile memory when said receiver is shipped from a factory.

11. The receiver according to claim 10, further comprising a case enclosing said nonvolatile memory, said interface circuit and said operation circuit, wherein

a symbol representing said unique identification number is indicated on said case.

12. The receiver according to claim 10, further comprising a transfer interface circuit transferring said unique identification number stored in said nonvolatile memory to said control unit via a network different from said network.
