Abstract

본 발명은 본체에 설치된 키이매트릭스와 리모콘 수광부에 대한 입력포트를 공용화 하는 기술에 관한 것으로, 종래의 키이신호 입력시스템에 있어서는 키이매트릭스를 통해 입력되는 키이신호를 병렬로 스캔하여 처리하게 되므로 많은 포트를 할당해야 되는 결함이 있고, 더욱이 키이매트릭스와 리모콘이 키이신호를 각각 디코딩하기 위해 별도의 프로그램을 사용하게 되어 처리과정이 복잡해지는 결함이 있었는 바, 본 발명은 이를 해결하기 위하여 제2키이매트릭스(13)에서 선택되는 키이신호에 대하여 제2리모콘집적소자(14)를 이용하여 리모콘(11)의 키이 신호와 동일한 형태로 출력한 다음 적분처리함으로써 리모콘 수광부 (12)의 출력 신호와 동일한 형태로 출력 할수 있게 되며, 이에 따라 상기 마이크로컴퓨터 (16)는 리모콘 (11)의 출력신호나 제1키이매트릭스(11A)의 출력신호를 동일포트 동일 프로그램으로 처리할 수 있다.The present invention relates to a technology for sharing an input port for a key matrix installed in a main body and a remote control receiver. In a conventional key signal input system, a key signal input through a key matrix is scanned and processed in parallel so that many ports are used. There is a defect that needs to be allocated, and furthermore, the key matrix and the remote controller use separate programs to decode the key signals, so that the process is complicated. Therefore, the present invention provides a second key matrix 13 to solve this problem. For the key signal selected in the) by using the second remote control integrated element 14 and output in the same form as the key signal of the remote control 11 and then integrated processing can be output in the same form as the output signal of the remote control receiver 12. Accordingly, the microcomputer 16 outputs the first signal or the first signal of the remote controller 11. The output signals of the matrix (11A) can be treated in the same program, the same port.
