Abstract

본 발명은 타이머에 시간 에러 발생시 그 시간 에러를 보정하도록하여 사용자가 원하는 시각에 디스플레이 되도록하는 방송 수신기의 디스플레이 타이머 에러 보정장치에 관한 것으로, 종래에는 크리스탈의 발진 주파수 오차나 주변회로의 오차에 의하여 타이머에 시간에러가 발생하므로써 그 에러 발생시마다 사용자가 에러를 수정해야 했으나, 본 발명에서는 제1, 2, 3 지연부 (5, 9, 13) 및 검출부 (16) 를 병렬로 접속하여 방송국에서 송신하는 정시를 알리는 시보 신호를 각각 검출하므로써 그 시보 신호에 따라 타이머 에러 보정이 이루어지도록 하므로 사용자가 원하는 시각에 디스플레이 되도록하여 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to a display timer error correcting apparatus of a broadcast receiver, which allows a timer to correct a time error when a time error occurs, so that the timer can be displayed at a desired time. The user had to correct the error every time the error occurred due to a time error. However, in the present invention, the first, second and third delay units 5, 9 and 13 and the detector 16 are connected in parallel and transmitted from a broadcasting station. Time signal error correction is performed according to the time signal by detecting the time signal informing each time signal, so that the above-mentioned defect can be improved by being displayed at a desired time.
