2. Description of the Related Art Currently, various home appliances such as televisions, videos, and air conditioners are used in each home. Most of the home electric appliances are accompanied by a remote controller equipped with an infrared transmitter, and the purchaser of the home electric appliances can remotely operate the home electric appliances within the range where infrared rays from the remote controller can reach the home electric appliances. It is possible to

However, when there is a shield or there is a distance between the home electric appliance and the remote controller, that is, when infrared rays emitted from the remote controller cannot reach, the home electric appliance is remoted using the existing remote controller. It was not possible to operate from.

In the above case, in the conventional technique, the following 2
There are two possible ways.

To give a concrete example, at present, there are home electric appliances that have an interface for connecting a telephone line and can be remotely operated by push button operation from an external telephone such as a mobile telephone / PHS or a public telephone. In addition, home electric appliances that have interfaces such as Ethernet (registered trademark) and IEEE 1394 and send back by TCP / IP or the like to enable remote operation have been developed.

Secondly, there is a method of using a computer with an infrared transmitter capable of emitting the same signal as an infrared signal emitted by a remote controller attached to a home electric appliance.
For example, there is a method disclosed in Japanese Patent Application No. 10-40057.

This system is composed of a personal computer and general home electric appliances such as television and video. The personal computer is connected to the provider's modem by a modem and a wired or wireless telephone line. And on the Internet, program data,
Other servers are connected. Further, the personal computer is equipped with a keyboard, a mouse, an infrared ray emitting section, a modem, and browsing software such as a WWW browser inside.

In the remote control method for home electric appliances in this system, first, when the operator performs a predetermined operation on the personal computer, the personal computer creates a command for accessing the program data server connected to the Internet. , Send via modem. This command is sent to the provider via a telephone line and a modem, and is sent to a program data server connected to the Internet via this command. Upon receiving this command, the program data server transmits the program data to the personal computer via the Internet. The personal computer takes in the program data and displays the program guide and various buttons on the display. The operator accesses the personal computer using a terminal equipped with browsing software such as a WWW browser and operates the program table and various buttons, so that the personal computer executes the operation contents on the TV / video through the infrared light emitting section.
