Abstract

본 발명은 텔레비젼 방송의 자동채널 기억방법에 관한 것으로, 사용자가 자동 채널기억의 모드를 선택하면 채널을 증가시키면서 채널을 선국하는 단계와, 기준 채널 데이타에 고정의 값을 가산한 PLL데이타를 튜너로 출력하고 AFT 전압을 입력받는 단계와, 상기의 AFT 전압과 기준전압을 비교하여 기준전압이 큰가를 확인하는 단계와, 기준전압이 큰경우 기준채널 데이타에 소정의 값을 감한 PLL데이타를 튜너로 출력하고 AFT 전압을 입력받는 단계와, 상기의 AFT 전압과 기준전압을 비교하여 기준전압이 작은가를 확인하는 단계들에 의해 정확히 정해진 범위안에 신호가 있는 채널만 선국하여 기억시키도록 한 것이다.The present invention relates to an automatic channel storage method for television broadcasting, comprising the steps of tuning a channel while increasing the channel when the user selects the automatic channel memory mode, and adding a fixed value to the reference channel data as a tuner. Outputting and receiving an AFT voltage; comparing the AFT voltage with a reference voltage to determine whether the reference voltage is large; and outputting PLL data obtained by subtracting a predetermined value from the reference channel data to the tuner when the reference voltage is large. By selecting the AFT voltage and comparing the AFT voltage with the reference voltage to confirm whether the reference voltage is small, only the channel having a signal within a predetermined range is tuned and stored.

Claims (1)

채널을 증가시키면서 채널을 선국하는 기능을 갖는 텔레비젼 방송의 자동채널 기억방법에 있어서, 채널을 증가시키면서 선국한 후 기준채널 데이타 보다 소정의 값만큼 큰 PLL 데이타를 튜너(4)로 출력하는 단계와, 튜너(4)로 부터 AFT 전압을 디지탈 값으로 입력받는 단계와, 기준전압이 AFT 전압 보다 큰가를 확인하는 단계와, 기준전압이 큰경우에 기준채널 데이타 보다 소정의 값만큼 작은 PLL 데이타를 튜너(4)로 출력하는 단계와, 튜너(4)로 부터 AFT 전압을 디지탈 값으로 입력받는 단계와, 기준전압이 AFT 전압 보다 작은가를 확인하는 단계와, 기준전압이 AFT 전압보다 작은경우에만 채널을 기억시킨 후 상기의 동작을 반복하는 단계들에 의해 수행됨을 특징으로 하는 텔레비젼 방송의 자동채널 기억방법.An automatic channel storage method for television broadcasting having a function of tuning a channel while increasing a channel, the method comprising: outputting, to the tuner 4, PLL data larger than a reference channel data after tuning by increasing the channel; Receiving the AFT voltage from the tuner 4 as a digital value; checking whether the reference voltage is greater than the AFT voltage; and, if the reference voltage is large, tune the PLL data smaller than the reference channel data by a predetermined value. 4) outputting, receiving the AFT voltage from the tuner 4 as a digital value, checking whether the reference voltage is less than the AFT voltage, and remembering the channel only when the reference voltage is less than the AFT voltage. And performing the above operations after repeating the above operations. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
