Abstract

A network system has a plurality of electronic devices connected to a network. At least one of the electronic devices receives a broadcast signal including data relating to an electronic device. The network system has a processing circuit that collates data contained in the broadcast signal with inherent information of an electronic device connected to the network, and generates a signal for causing at least one of the electronic devices to execute predetermined processing according to a result of the collation.

Claims

1. A network system comprising:

a plurality of electronic devices connected to a network, at least one of the electronic devices being capable of receiving a broadcast signal, the broadcast signal including data relating to an electronic device; and

a processing circuit that collates data contained in the broadcast signal with inherent information of an electronic device connected to the network, and generates a signal for causing at least one of the electronic devices to execute predetermined processing according to a result of the collation.

2. A network system according to claim 1, wherein the processing circuit is disposed in a chassis of the electronic device which is capable of receiving the broadcast signal.

3. A network system according to claim 1, wherein each of the electronic devices has a separate chassis.

4. A network system according to claim 1, wherein the predetermined processing is specified by the data contained in the broadcast signal.

5. A network system according to claim 1, wherein the processing circuit generates a signal for causing the electronic device which is collated in inherent information to execute the predetermined processing.

6. A network system according to claim 1, wherein the processing circuit generates a signal for causing an electronic device different from the electronic device which is collated in inherent information to execute the predetermined processing.

7. A network system according to claim 1, wherein the predetermined processing is version up processing for software held in the electronic device.

8. A network system according to claim 1, wherein the predetermined processing is print processing.

9. A network system according to claim 1, wherein the predetermined processing is display processing.

10. An electronic device which can be connected to a network connected to other electronic device, the electronic device comprising:

a receiver that receives a broadcast signal, the broadcast signal including data relating to an electronic device; and

a processing circuit that collates data contained in the broadcast signal with inherent information of an electronic device connected to the network, and generates a signal for causing at least one of the electronic devices to execute predetermined processing according to a result of the collation.

11. A program for causing an electronic device which can be connected to a network connected to other electronic device and which can receive a broadcast signal to execute the steps of:

receiving a broadcast signal, the broadcast signal including data relating to an electronic device;

collating data contained in the broadcast signal with inherent information of an electronic device connected to the network; and

generating a signal for causing at least one of the electronic devices to execute predetermined processing according to a result of the collation.

12. A broadcast method for transmitting a broadcast signal, wherein

the broadcast signal includes data relating to a different electronic device other than an electronic device receiving the broadcast signal, and

the data comprises first information to be collated with inherent information of the different electronic device, and second information representing predetermined processing to be executed according to a result of the collation of the first information with the inherent information.
