Abstract

본 발명은 영상신호 입력 유무에 따른 예약녹화 제어회로 및 그 방법에 관한 것으로서 보다 상세하게는 예약 녹화시 예약 녹화 초기에 입력신호의 유무를 판별하여 무신호일 경우 녹화를 수행하지 않고 대기 상태 및 경보음을 발생시킬 수 있게 하여 주위의 사용자에게 기기의 장애발생상태를 알리는 이후 장애가 개선되어 정상적으로 신호가 입력되면 예약녹화를 수행하도록 함으로써 예약 녹화를 하지 못하는 것을 사전에 방지할 수 있도록 한 것이다.The present invention relates to a reservation recording control circuit according to the presence or absence of a video signal and a method thereof, and more particularly, to determine the presence or absence of an input signal at the beginning of the reservation recording at the time of the reservation recording, and to perform the standby state and the alarm sound without performing the recording in the absence of a signal. After the system is notified of the fault condition of the device to neighboring users, the fault is improved, and if the signal is input normally, the scheduled recording is performed to prevent the scheduled recording from being prevented.

특정적인 구성으로는 다수의 입력라인중에서 하나의 예약 녹화 신호원을 자동으로 선택하는 입력 절환 스위칭 수단과, 상기 입력 절환 스위칭 수단의 선택신호를 입력신호로 받아서 영상신호가 동기신호를 검출해내는 동기 검출수단과, 상기 동기 검출수단의 검출신호의 유무에 따라 예약녹화 제어신호를 제어하여 예약 녹화 수행여부를 판단하고 경보음발생 제어신호를 제어하여 경보음 발생여부를 판단하는 주제어수단과, 상기 주제어수단에 의해 제어되어 외부로 경보음을 발생시키는 경보음 발생수단으로 구성함에 있으며, 예약 녹화 초기에 비디오/오디오 잭이나 고주파 수신용 케이블등의 입력라인을 통해 들어오는 영상 신호의 유무를 판단하는 영상신호 판단단계와, 상기 영상신호 판단단계의 판단결과 영상신호가 입력되지 않으면 장애상태로 판단하여 장애가 개선될때까지 대기상태를 유지시키면서 경보음 발생 제어신호를 발생시키는 예약녹화 대기단계와, 상기 영상신호 판단단계의 판단결과 영상신호가 입력되는 경우나 상기 예약녹화 대기단계에서 장애가 개선되는 경우 예약된 시간동안에 정상적인 예약녹화를 실시한 후 종료하는 예약녹화 수행단계로 이루어짐에 있다.Specifically, the input switching switching means for automatically selecting one reserved recording signal source from a plurality of input lines, and the synchronization of the video signal detecting the synchronization signal by receiving the selection signal of the input switching switching means as an input signal. Main control means for controlling the reservation recording control signal according to the presence or absence of the detection signal of the synchronous detection means, and determining whether to perform the reserved recording and controlling the alarm sound generation control signal to determine whether the alarm sound is generated; It is composed of alarm sound generating means which is controlled by means and generates alarm sound to the outside. Video signal which judges the presence or absence of video signal coming in through input line such as video / audio jack or high frequency receiving cable at the beginning of scheduled recording. If the video signal is not input as a result of the determination step and the determination of the video signal determination step, the fault state The standby recording standby step of generating an alarm sound control signal while maintaining the standby state until the failure is corrected, and when the video signal is input as a result of the determination of the video signal determination step or the standby recording standby step is improved. In this case, the reservation recording is performed after the normal reservation recording is performed during the reserved time.
