Abstract

정규 방송시간 내에서는 약전계조건에서도 전원이 차단되지 않도록 하는 텔레비젼 수상기의 전원차단회로가 개시된다.A power cut-off circuit of a television receiver is disclosed so that power is not cut off even under weak electric field conditions.

본 발명에 따른 전원차단회로는 소정의 시각구간을 설정하며, 설정된 시각구간을 나타내는 상태정보를 발생하는 시각정보발생부; 방송신호의 레벨을 판단한 결과 및 시각정보 발생부에서 발생된 상태정보를 참조하여 소정의 시각구간에 있어서유효한 방송신호가 유입되지 않는 가를 판단하는 논리연산부를 구비함을 특징으로 한다.According to the present invention, there is provided a power cut-off circuit for setting a predetermined time interval and generating a state information indicating the set time interval; And a logic calculator configured to determine whether a valid broadcast signal is not introduced in a predetermined time period by referring to the result of determining the level of the broadcast signal and the state information generated by the time information generator.

본 발명에 따른 전원차단장치는 유입되는 방송신호의 레벨이 미약할 경우에도 방송시간 내에서는 텔레비젼 수상기의 전원을 차단시키지 않게 함으로써 시청시의 불편함을 제거하는 효과를 갖는다.The power cutoff device according to the present invention has the effect of eliminating inconvenience in viewing by not interrupting the power of the television receiver during the broadcast time even when the level of the incoming broadcast signal is weak.
