리모콘과 OSD를 이용한 사칙연산 처리방법How to handle arithmetic operations using remote control and OSD

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 발명에 의한 바람직한 일 실시예의 흐름도.2 is a flow chart of a preferred embodiment according to the present invention.

Claims (1)

OSD키, 덴키, 계산키, 덧셈키, 뺄셈키, 곱셈키, 나눗셈키 및 결과키를 구비한 리모콘 수단과, OSD신호를 발생하는 OSD발생수단과, 휘도-채도 분리수단과, 상기 OSD신호와 영상신호를 디스플레이하는 화상표시수단과, 상기 리모콘수단으로부터 송출된 키 신호를 수신하여 해독하고 해독된 정보에 따라 상기 OSD발생수단을 제어하여 OSD신호를 발생하고 이 OSD신호를 상기 화상표시수단에 디스플레이 되도록 제어하는 마이콤을 구비한 리모콘과 OSD를 이용한 사칙연산처리방법에 있어서, 상기 계산키 입력이 있을 때에 계산모드 플래그 레지스터를 판단하여 값을 지정하고, OSD서브루틴을 불러서 화면을 클리어 시키는 제1과정;상기 제1과정에서 계산키 입력이 없을 때에 상기 계산모드 플래그 레지스터의 값을 판단하는 제2과정;상기 제2과정에서 계산모드 플래그 레지스터의 값이 “1”일때 입력키를 판단하는 제3과정과;상기 제3과정에서 입력키가 계산모드에 타당하면 OSD서브루틴을 불러서 상기 입력키의 데이타를 화면에 디스플레이시키고 저정하며, 데이타 플래그 레지스터를 세트시키는 제4과정;상기 데이타 플래그 레지스터의 값이 “1”일때 결과키를 판단하는 제5과정;상기 제5과정에서 결과키 입력이 있고 곱셈키 입력이 있을 때에 상기 곱셈키 전, 후의 데이타를 처리하고, 그 결과를 RAM에 보관하며, 곱셈키를 클리어 시키는 제6과정;상기 제6과정에서 곱셈키 입력이 없고 나눗셈키 입력이 있을 때에 상기 나눗셈키 전, 후의 데이타를 처리하고, 그 결과를 RAM에 보관하며, 나눗셈키를 클리어 시키는 제7과정;상기 제7과정에서 나눗셈키 입력이 없고 덧셈키 입력이 있을 때에 상기 덧셈키 전, 후의 데이타를 처리하고, 그 결과를 RAM에 보관하며, 덧셈키를 클리어 시키는 제8과정;상기 제8과정에서 덧셈키 입력이 없고 뺄셈키 입력이 있을 때에 상기 뺄셈키 전, 후의 데이타를 처리하고, 그 결과를 RAM에 보관하며, 뺄셈키를 클리어 시키는 제9과정;그리고 상기 제9과정에서 뺄셈키 입력이 없을 때에 OSD서브루틴을 불러서 최종적인 결과값을 화면에 디스플레이시키고, 데이타 플래그 레지스터를 클리어 시키는 제10과정으로 이루어짐을 특징으로 하는 리모콘과 OSD를 이용한 사칙연산처리방법.A remote control means having an OSD key, a denkey, a calculation key, an addition key, a subtraction key, a multiplication key, a division key and a result key, an OSD generating means for generating an OSD signal, a luminance-saturation separating means, the OSD signal and Image display means for displaying an image signal, and receiving and decoding key signals transmitted from the remote control means, and controlling the OSD generating means according to the decoded information to generate an OSD signal and display the OSD signal on the image display means. In the arithmetic operation processing method using a remote control and an OSD equipped with a microcomputer to control, the first process of determining the calculation mode flag register when the calculation key input, the value is specified, and calling the OSD subroutine to clear the screen A second process of determining a value of the calculation mode flag register when there is no input of a calculation key in the first process; a calculation mode flag in the second process A third step of determining an input key when the value of the jitter is “1”; and in the third step, when the input key is in the calculation mode, an OSD subroutine is called to display and store the data of the input key on the screen and save the data. A fourth step of setting a flag register; a fifth step of determining a result key when the value of the data flag register is “1”; before the multiplication key when there is a result key input and a multiplication key input in the fifth step; A sixth step of processing the subsequent data, storing the result in RAM, and clearing the multiplication key; processing the data before and after the division key when there is no multiplication key input and a division key input in the sixth step, A seventh step of storing the result in the RAM and clearing the division key; when there is no division key input and there is an addition key input in the seventh step, data before and after the addition key are processed. And storing the result in the RAM and clearing the addition key; when there is no addition key input in the eighth step and there is a subtraction key input, process the data before and after the subtraction key, and store the result in RAM. In step 9, the subtraction key is cleared; and in the ninth step, when there is no subtraction key input, the OSD subroutine is called to display the final result on the screen and the data flag register is cleared. The four arithmetic operation method using the remote control and OSD characterized in that made. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
