Abstract

본 발명은 텔레비전 수상기의 온타임 제어방법 및 장치에 관한 것으로서, 이는 낮과 밤의 일정하지 않은 시간대에 일조량을 검출하여서 어느 정도 밝아지면 자동으로 텔레비전 수상기의 온타임을 가변시켜 파워를 켜주도록 한 것이다.The present invention relates to a method and apparatus for controlling on-time of a television receiver, which detects the amount of sunshine during an irregular time zone during the day and night, and automatically turns on the power by varying the on-time of the television receiver when the brightness is somewhat brighter. .

이와같은 본 발명의 목적은 밤과 낮의 조도량을 전기적신호로 검출하는 광검출수단과; 상기 광검출수단에서 검출한 조도량신호를 디지탈 신호로 변환하여 출력하는 아날로그/디지탈 변환수단과; 상기 아날로그/디지탈 변환수단에서 얻어진 디지탈 조도량과 설정값을 비교하여 그 비교결과 및 리모트 콘트롤러로부터의 파워 온타임을 결정하는 자동모드 및 수동모드의 정보에 따라 파워스위치의 차단 및 도통여부를 결정하는 등 일련의 텔레비전 수상기의 전체 시스템 동작을 제어하는 마이크로 프로세서와; 상기 마이크로 프로세서의 제어신호에 따라 이득값을 설정하여 음성증폭수단을 통해 방송채털의 증폭도를 변화시켜 주는 이독조절수단을 포함하여 이루어짐으로서 달성된다.The object of the present invention as described above is light detection means for detecting the amount of illumination of the night and day as an electrical signal; Analog / digital conversion means for converting the illumination intensity signal detected by the light detection means into a digital signal and outputting the digital signal; Comparing the digital illuminance obtained from the analog / digital converting means and the set value, determining whether the power switch is cut off or not, according to the comparison result and the information of the automatic mode and the manual mode which determine the power on time from the remote controller. A microprocessor for controlling the overall system operation of a series of television receivers; It is achieved by including a read control means for setting the gain value in accordance with the control signal of the microprocessor to change the amplification degree of the broadcast channel through the voice amplification means.
