## 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

### Claim 1

A network system comprising:
a TV apparatus and an electronic device connected to the TV apparatus via a network, the TV apparatus being capable of receiving a broadcast signal, wherein the broadcast signal contains identification data identifying one of electronic devices connectable to the network, which is not capable of receiving the broadcast signal, and control data for controlling a version-update of a control software to be executed on the electronic device identified by the identification data,
wherein the TV apparatus comprises:
a storage unit that stores the identification data and the control data contained in the received broadcast signal;
a control unit that collates the identification data of the electronic device with inherent information of the electronic device, inquires whether the identified electronic device is in an on-state, and in a case where the identified electronic device is in an on-state, transmits the control data stored in the storage unit to the identified electronic device via the network so as to execute a version-update of control software stored in a memory unit in the identified electronic; and
wherein the identification data contains a name of a manufacturer for the electronic device to be controlled, and the identification data and the control data are contained in a signal of a commercial message (CM) broadcast of the manufacturer.

### Claim 2

A TV apparatus which can be connected to a network and is connected to an electronic device via the network, the TV apparatus comprising:
a receiver that receives a broadcast signal, the broadcast signal containing identification data identifying one of the electronic devices on the network, which is not capable of receiving the broadcast signal, and control data for controlling a version-update of a control software to be executed on the electronic device identified by the identification data;
a storage unit that stores the identification data and the control data contained in the received broadcast signal;
a control unit that collates the identification data of the electronic device with inherent information of the electronic device, inquires whether the identified electronic device is in an on-state, and in a case where the identified electronic device is in an on-state, transmits the control data stored in the storage unit to the identified electronic device via the network so as execute a version-update of control software stored in a memory unit in the identified electronic; and
wherein the identification data contains a name of a manufacturer for the electronic device to be controlled, and the identification data and the control data are contained in a signal of a commercial message (CM) broadcast of the manufacturer.

### Claim 3

A method of controlling a software update for an electronic device connected to a TV apparatus on a network utilizing a broadcast signal, wherein the electronic device is not capable of receiving the broadcast signal, comprising the steps of:
transmitting a broadcast signal, wherein the broadcast signal includes identification data identifying one of electronic devices connectable to the network, which is not capable of receiving the broadcast signal, and control data for controlling a version-update of a control software to be executed on the electronic device identified by the identification data;
receiving the broadcast signal by the TV apparatus connected to the network;
storing in a storage unit of the TV apparatus, the identification data and the control data contained in the broadcast signal received by the TV apparatus;
collating, by the TV apparatus, the identification data of the electronic device with inherent information of the electronic device, inquiring whether the identified electronic device is in an on-state, and in a case where the identified electronic device is in an on-state, transmitting, by the TV apparatus to the electronic device via the network, the control data stored in the storage unit so as to execute a version-update of control software stored in a memory unit in the identified electronic device; and
wherein the identification data contains a name of a manufacturer for the electronic device to be controlled, and the identification data and the control data are contained in a signal of a commercial message (CM) broadcast of the manufacturer.

### Claim 4 (depends on 1)

A network system according to claim 1, wherein in a case where the identified electronic device is not in an on-state, the control unit controls a display unit of the TV apparatus to display a message urging a user to set the identified electronic device to an on-state.
