Claims (1)

비디오 테이프 레코오더의 캡스턴 제어방법에 있어서, 전원공급시 시스템과 저장된 데이터를 초기화한 다음 입력포트를 통해 입력되는 입력상태를 체크함으로 캡스턴 구동방식을 판단하여 캡스턴 구동방식에 대한 플래그를 세트하는 제 1과정과, 상기 제 1과정 수행후 주변회로에 전원공급을 제어한 다음 키데이터가 입력되었는가 검사하는 제 2과정과, 상기 제 2과정에서 키데이터가 입력되었을시 입력된 키데이터에 대한 기능을 수행하는 제 3과정과, 상기 제 3과정에서 키데이터가 입력되지 않았을시나 상기 제 3과정 수행후 현재 작동모드와 다음 작동모드를 체크하여 세트되어져 있는 캡스턴 구동방식에 따라 캡스턴을 제어한 다음 작동상태를 현재 모드와 관련시켜 검사한후 시스템의 작동상태를 현재 모드에 비교함으로 이상 작동상태가 발생하였는가 체크하여 이상 작동상태를 정상 작동상태가 되도록 시스템을 제어한 다음 상기 제 2과정으로 되돌아가는 제 4과정과, 일정주기로 발생되는 인터럽트가 발생될때마다 타이머의 시간을 가산카운팅하고 선택되어진 키데이터를 입력하여 저장하여 센서들에 의해 검출된 감지신호들을 입력하여 저장한 다음 인터럽트 발생전의 루틴으로 되돌아가는 제 5과정으로 이루어짐을 특징으로 하는 방법.A capstan control method of a video tape recorder, the method comprising: setting a flag for a capstan driving method by determining a capstan driving method by initializing a system and stored data upon powering and then checking an input state input through an input port; And a second process of controlling power supply to a peripheral circuit after performing the first process, and then checking whether key data is input, and performing a function on key data input when the key data is input in the second process. When the key data is not input in the third process and the third process, but after performing the third process to check the current operation mode and the next operation mode to control the capstan in accordance with the set capstan driving method and then the operation state After checking in relation to the current mode, abnormal operation state can be occurred by comparing the operation state of the system with the current mode. The controller controls the system so that the abnormal operating state becomes a normal operating state by checking and then counts the time of the timer and counts the selected key data every time the interrupt occurs occurring at a certain period. And a fifth process of inputting and storing the input and storing the detection signals detected by the sensors, and returning to the routine before generating the interrupt. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
