The present invention relates to a method for controlling a remote control receiver of a home appliance, and more particularly, to include a storage unit for storing various remote control codes in a home appliance, and to search for a third-party remote control code inputted when a user wants to change to a third-party remote control. The present invention relates to a control method of a remote control receiver of a home appliance that not only enables a third party remote controller to be used, but also allows many third party remote controllers to be used by adding and updating a new remote control code.

In recent years, it is difficult to provide all of these keys on the front of the main body of the home appliance because of the increasing number of keys for using the functions due to the variety of home appliance functions. In order to alleviate the inconvenience of having to operate in close proximity to the equipment, a remote controller (Remote Controller: commonly referred to as a Remocon) has been widely used to input various control commands through key input wirelessly from a remote place.

By the way, when using different kinds of home appliances in the same home to use the corresponding number of remote control is not only difficult to manage multiple remote controls, but also when the user wants to select and use new home appliances every time The need to change the mocon was accompanied by inconvenience.

Therefore, in order to solve such inconveniences, an integrated remote controller capable of controlling several devices with a single remote controller has recently been proposed. Such integrated remote controllers target similar home appliances. In other words, remote controllers having keys having the same function are used together. An example is a remote control in which a remote control of a television receiver and a remote control of a VCR are integrated.

In the integrated remote controller, a user first selects a desired device by operating a slide switch, and then selects all models in the corresponding device to perform a desired function.

For example, in order to watch television, the slide switch is set to the television setting position and the power is turned on to perform a channel selection operation. To operate the video, the slide switch is set to the video setting position and the power is turned on. Play and stop are performed at.

As shown here, in the case of the integrated remote controller 5 for controlling the home appliances such as TV, VCR, DVD player, etc., if each TV, VCR, etc. is not a product of the same company, The code of the home appliance and the code of the integrated remote controller must be matched with each other. To do this, the integrated remote controller manufacturer stores the codes of each product on the integrated remote controller and sets the code so that the user can match the code when using the integrated remote controller. A button is provided to select the manufacturer and product type so that the code can be tailored.

2 is a block diagram illustrating a general integrated remote controller.

As shown here, a key array 10 for inputting a control command to operate a home appliance, an address generator 20 for generating a predetermined address according to the operation of the key array 10, and an address generator ( A storage unit 30 for outputting a mapping code for controlling a corresponding household appliance according to the address output from the unit 20), a conversion unit 40 for converting the mapping code output from the storage unit 30 into a wireless signal, Infrared generator 50 for generating an infrared ray in accordance with the radio signal converted by the conversion unit 40.

Accordingly, the key array 10 of the integrated remote controller 5 may be used by the user to match the codes of the integrated remote controller 5 with the household electrical appliance that the user wants to control remotely, such as a TV, a VCR, a DVD player, or the like. In order to input a command by pressing a corresponding key, the address generator 20 stores the combined address according to the input key signal based on the state information for distinguishing the TV mode, the VCR mode, and the like stored in the storage unit ( 20), and the storage unit 30 maps the home appliance control related information corresponding to the address and applies it to the conversion unit 40. In addition, the conversion unit 40 converts the mapped home appliance control related information into a serial signal such as a PWM (Pulse Width Modulation) signal in order to transmit the wireless signal as a wireless signal, and the infrared ray generation unit 50 converts the wireless signal into the serial signal. Emit infrared radiation.

Then, the home appliance receives the infrared rays through the infrared receiver and converts the converted home appliance control related information to control the home appliance according to the control command.

As such, in order to control home appliances through the integrated remote controller, if the code transmitted from the integrated remote controller and the code stored in the home appliance are the same, only one code is stored in the home appliance, and the various remote codes are selectively selected through the integrated remote controller. By matching the code of the home appliance to control the home appliance.

However, if there is no integrated remote control that can change its own remote control or code provided with home appliances, even if you have a lot of third-party remote control, you cannot control the home appliances, so you can add your own remote control or integrated remote control to control home appliances. There is a problem that must be purchased.

The present invention was created to solve the above problems, an object of the present invention is to use a third-party remote control by retrieving and setting a third-party remote control code input when you want to use a third-party remote control by storing a variety of remote control codes in home appliances In addition, the present invention provides a method of controlling a remote control receiver of a home appliance, which enables a number of third-party remote controls to be used by adding and updating a new remote control code.
