Abstract

본 발명은 리모콘신호 수신장치 및 코드데이터 검출방법에 관한 것으로, 리모콘으로부터 송출되는 리모콘 신호가 기기 내의 CPU가 인식할 수 있는 데이터로 변화되어 메모리에 저장되고, CPU는 메모리에 저장되어 있는 복수개의 데이터 중에 코드데이터를 검출한 다음 그에 상응하는 기능 수행시키기 위한 제어신호를 발생하며, CPU로부터의 제어신호에 의거하여 기기의 소망하는 기능이 수행되므로써, 수신장치 내의 마이컴 없이도 기기 내의 CPU가 리모콘신호를 인식할 수 있으므로, 수신장치를 간소화할 수 있는 동시에 제작비용을 절감시킬 수 있고, CPU에 의해 인식된 리모콘신호를 이용하여 다른 어떠한 기기의 기능을 손쉽게 제어할 수 있도록 한 것이다.The present invention relates to a remote control signal receiving apparatus and a code data detecting method, wherein a remote control signal transmitted from a remote control is converted into data that can be recognized by a CPU in the device and stored in a memory, and the CPU stores a plurality of data stored in the memory. The controller detects the code data and then generates a control signal for performing a corresponding function, and a desired function of the device is performed based on the control signal from the CPU, so that the CPU in the device recognizes the remote control signal without a microcomputer in the receiving device. As a result, the receiver can be simplified and the manufacturing cost can be reduced, and the functions of any other device can be easily controlled by using a remote controller signal recognized by the CPU.
