Abstract

Controllable units such as a television set or a playback unit are connected to a home network. A gateway connects the home network with the Internet and, at the same time, forwards externally-supplied data to the home network. A portable terminal sends HTML data for controlling controllable units and allows a user to browse HTML data sent from the gateway, either via a wireless data communication line at home or via the Internet away from home.

Claims

1. A control data system comprising:

a home network;

at least one controllable unit connected to said home network and remotely controlled by control data transmitted via said home network;

a gateway at least comprising;

a connection unit connecting said home network to the Internet;

a forwarding unit forwarding externally- supplied data to said home network; and

a first home network connection unit communicating data via a wireless data communication line; and

a portable terminal comprising;

a second home network connection unit for wireless data communication with said first home network connection unit;

a control data transmission function for transmitting control data for controlling said controllable unit; and

a browse function for browsing HTML data transmitted from said gateway,

wherein said control data and said HTML data are transmitted via said wireless data communication line when the data communication is established between said first home network connection unit and said second home network connection unit or via said Internet when the data communication is not established between said first home network connection unit and said second home network connection unit.

2. The control data system according to

claim 1

wherein said gateway further comprises accumulation means for accumulating externally-supplied program data or contents and wherein said portable terminal browses HTML data on the program data or contents accumulated in said accumulation means via said home network or said Internet for controlling said controllable unit with the control data.

3. The control data system according to

claim 1

wherein said portable terminal has a function for monitoring a presence of a nearby gateway via wireless communication and, when said portable terminal requests a connection to said gateway in which said portable terminal is not registered as a format user, said gateway allows said portable terminal to connect to the home network as a guest which may execute only limited services.

4. The control data system according to

claim 1

wherein said controllable unit has a WWW server function transmitting control code for controlling operation and wherein said portable terminal has a control data transmission function transmitting control data for controlling the controllable unit based on the control code received from the WWW server function.

5. A method for transmitting control data among at least one controllable unit, a gateway, and a portable terminal interconnected via a home network, wherein control data for controlling said controllable unit is transmitted, and HTML data from said gateway is browsed, either via wireless data communication line when data communication is established between said gateway and said portable terminal or via said Internet in a location where data communication is not established between said gateway and said portable terminal.
