[Prior art]

 Traditional appliance remote controls have different setting ciphers for different manufacturers, and different appliances use different ciphers. Therefore, the TV remote control cannot control the cooler, and the remote control of the cooler cannot activate the VCR. For this reason, if consumers have appliances from different manufacturers, they will have to find the necessary remote controller among many remote controllers at the time of use, which causes a great deal of inconvenience when using the appliance. Was. In addition, when the remote control breaks, it is common to ask the manufacturer for a replacement, which is cumbersome and inconvenient. In order to deal with such a situation, there are various plans for improvement as described below. 1.2 Method with two remote controls This method is a precautionary measure when the remote control is broken or lost, but it is necessary to prepare another remote control even when one remote control is normal. It is unacceptable to consumers, so this method is only applied when the merchant offers a replacement to the consumer. 2. Code input method Currently, a certain company allows all manufacturers to store dedicated encryption codes that can be used by various appliances of each manufacturer in the same remote control and display them with multiple sets of representative codes. We offer remote control. Consumers enter and set the representative code of the manufacturer of the product corresponding to the remote control each time they use it. The biggest problem with such a method is that the consumer must check the list by himself and set the representative code corresponding to the appliance to be used on the remote control, and each time the appliance to be used is updated, a new one is required. It is necessary to set a representative code corresponding to that. Further, if there are multiple representative codes even within the same manufacturer, the setting process is complicated and it is difficult to search, and in order to memorize all the electric appliance types, Therefore, it was necessary to add many switching keys on the remote control faceplate, which increased the volume of the remote control. 3. Semi-automatic code search method The setting method of this method is that the appliance responds by pressing the power key on the remote control constantly for the appliance you want to remote control and emitting a code with one different frequency each time you press the key Perform further setting operations when the power on / off operation occurs. In this method, the power key must be constantly pressed to continuously emit codes of different frequencies, and in the current situation where there are many products and manufacturers, the time required for code search becomes longer, and there are many operational difficulties. was there. Furthermore, one more set time is required after the completion of the code search, and if the key is not set even if the set time is exceeded, the search result will expire and a new code search operation must be performed, which is inconvenient to use. there were.
