Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
녹화재생기Record player
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
비디오/오디오 입출력을 자동으로 인식하여 입·출력모드를 절환하는 회로 및 방법을 제공함에 있다.The present invention provides a circuit and method for automatically switching video input / output modes by recognizing video / audio input / output.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
비디오 입출력 잭, 오디오 입출력 잭 및 상기 비디오 입출력 잭의 비디오신호 케이블과의 접속 여부에 따라 제1 및 제2상태를 갖는 잭입력신호를 발생하는 잭입력판단부를 구비하여 외부에서 입력되는 비디오 및 오디오신호를 기록하는 입력모드로 동작하거나 그 기록된 신호를 재생하여 외부로 출력하는 출력모드로 동작하는 녹화재생기의 비디오/오디오 입출력 자동 인식방법에 있어서, 상기 잭입력신호의 상태를 체크하여 제1상태일 시 상기 내부 및 외부간 비디오/오디오신호의 전달경로를 차단한 후 상기 비디오신호 케이블을 통해 입력되는 비디오신호의 유·무를 판단하여 비디오신호가 있으면 상기 입력모드로 설정하고, 상기 잭입력신호가 제1상태일 시 상기 출력모드로 설정함을 특징으로 한다.A video input / output jack having a video input / output jack, an audio input / output jack, and a jack input determining unit for generating jack input signals having first and second states according to whether the video input / output jack is connected to a video signal cable or not. A video / audio input / output automatic recognition method of a recording player operating in an input mode for recording a signal or in an output mode for reproducing and outputting the recorded signal to the outside, wherein the state of the jack input signal is checked and After cutting the transmission path of the video / audio signal between the inside and the outside, it is determined whether there is a video signal input through the video signal cable, and if there is a video signal, the input mode is set. It is characterized by setting to the output mode when in one state.
