Abstract

본 발명은 오프타이머기능을 설정한 상태에서 무신호방송이 일정시간 지속되면 자동으로 영상을 어둡게 함과 아울러 음성레벨을 낮출 수 있도록 하는 텔레비젼의 오프타이머기능 설정시 영상밝기와 음성레벨을 조정하는 방법을 제공한다.The present invention provides a method for adjusting the video brightness and the audio level when setting the TV's off-timer function to automatically darken the video and lower the audio level when a signal-free broadcasting continues for a predetermined time while the off-timer function is set. To provide.

본 발명은 소정 채널의 방송신호를 수신하여 영상재생 및 음성재생함과 아울러 오프타이머기능을 구비한 텔레비전에 있어서, 소정 시간 경과후에 전원공급을 오프시키고자 해당 키조작을 통해 오프타이머기능을 설정하는 단계와, 상기 오프타이머기능의 설정에 의한 예약시간이 도래하였는지를 판단하는 단계와, 상기 예약시간이 도래하였으면 선국중인 채널이 무신호채널인지 검출하고, 무신호 채널이 선국되는 지속시간이 사전 설정된 기준시간보다 큰지를 판단하는 단계 및 상기 지속시간이 기준시간보다 커지는 시점부터 영상밝기와 음성레벨을 각각 설정된 값으로 조정하는 단계를 구비하여 이루어지는 것을 특징으로 한다.According to the present invention, in a television having an off-timer function by receiving a broadcast signal of a predetermined channel and setting the off-timer function through a corresponding key operation to turn off the power supply after a predetermined time has elapsed. Determining whether the reservation time by the setting of the off-timer function has arrived; and when the reservation time arrives, detecting whether a channel being tuned is a no-signal channel, and a preset time duration for tuning the no-signal channel is preset. And determining whether the time is greater than the time and adjusting the image brightness and the audio level to the set values from the time when the duration is greater than the reference time.
