Abstract

본 발명은 시간 압축 주문형 비디오용 브이.씨.알에 사용되는 프로그램서치 장치에 관한 것으로, 사용자의 명령을 입력하기 위한 키 입력부(10)와, 키 입력부(10)의 키 입력 신호에 따른 제어 신호를 발생하는 제어부(20)와, 오디오 신호를 녹음 및 재생하는 오디오 헤드(30)와, 오디오 헤드(30)에서 재생된 오디오 신호를 처리하는 재생 신호 처리부(40)와, 시간 압축 디지탈 데이터로 녹화된 프로그램의 재생시의 재생 신호 처리부(40)에서 처리된 오디오 신호를 뮤트(mute)시키는 오디오 뮤트부(50)와, 시간 압축 디지탈 데이터로 녹화된 프로그램 재생시 재생 신호 처리부(40)에서 처리되어 출력하는 오디오 신호의 레벨을 검출하여 제어부(20)로 제공하는 레벨 검출부(60)와, 시간 압축 디지탈 데이터를 녹화할 때 가청 주파수 신호를 발생하는 발진부(80)와, 일반적인 녹화 모드시에는 통상의 음성신호를 처리하고 시간 압축 디지탈 데이터를 녹화할 때에는 발진부(80)로부터 제공되는 가청 주파수 신호를 처리하는 녹음 신호 처리부(70)를 포함하고 구성되어 녹화가 시작되는 부분과 녹화가 끝나는 부분을 쉽게 검출하여 다수의 프로그램중 사용자가 시청을 원하는 프로그램을 쉽게 찾을 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program search device used for a video compression on-demand V.C. egg, the control signal according to a key input signal of a key input unit 10 and a key input unit 10 for inputting a user's command. A control unit 20 for generating a signal, an audio head 30 for recording and reproducing an audio signal, a reproduction signal processing unit 40 for processing an audio signal reproduced in the audio head 30, and recording with time-compressed digital data. The audio muting unit 50 for muting the audio signal processed by the reproduction signal processing unit 40 at the time of reproducing the programmed program, and the reproduction signal processing unit 40 at the time of reproducing the program recorded with the time-compressed digital data. A level detector 60 for detecting and providing a level of the audio signal to the controller 20, an oscillator 80 for generating an audible frequency signal when recording time-compressed digital data, and In the recording mode, the recording signal processing unit 70 is configured to process a normal audio signal and to process an audible frequency signal provided from the oscillator 80 when recording time-compressed digital data. Is easily detected by the end of the number of programs so that the user can easily find the program you want to watch.
