본 고안은 위성방송수신가능한 텔레비젼의 전원공급장치 관한 것으로, 특히 영상수신회로를 구동하기 위한 전원공급수단과 음성수신회로를 구동하기 위한 전원공급수단을 분리한 위성방송수신 텔레비젼의 전원공급장치에 관한 것이다.The present invention relates to a power supply of a television capable of receiving satellite broadcasting, and more particularly, to a power supply of a satellite broadcasting television separated from a power supply means for driving an image receiving circuit and a power supply means for driving an audio receiving circuit. will be.
위성방송을 수신하기 위해서는 위성방송수신장치가 필요하다. 그래서 일반 텔레비젼과 위성방송수신장치를 접속하여 사용하였으나, 그에 따른 불편으로 인하여 텔레비젼 세트안에 위성방송수신장치를 내장한 일체형 위성방송수신텔레비젼이 이미 고안되었다.In order to receive satellite broadcasts, a satellite broadcast receiver is required. So, although general TV and satellite broadcasting receiver are connected and used, due to inconvenience, integrated satellite broadcasting television with satellite broadcasting receiver is already devised.
제1도는 종래의 전원공급장치의 회로도이다. 제1도에 있어서, 주전원(10)은 전원코드의 접속에 의해 텔레비젼 세트에 인가된다. 전원코드를 콘센트에 접속시키면 수평드라이브전원과 튜닝을 위한 전원이 공급되고 또한 사용자의 명령을 입력하여 각 기능을 수행하는 마이콤의 전원이 인가된다. 제1도에서 저항(R3)을 통해 인가되는 5V가 마이콤을 구동시키기 위한 전원이다.1 is a circuit diagram of a conventional power supply. In Fig. 1, the main power source 10 is applied to the television set by connection of a power cord. When the power cord is connected to the outlet, the horizontal drive power and the power for tuning are supplied, and the power of the microcomputer that performs each function by inputting the user's command is applied. In FIG. 1, 5V applied through the resistor R3 is a power source for driving the microcomputer.
전원코드만 접속시키고 전원키를 온(ON)시키지 않은 상태를 스탠바이(STAND-BY)상태라 하며, 스탠바이가 온(ON)이면 npn트랜지스터(Q2)가 오프(OFF)되고 또한 pnp트랜지스터(Q1)도 오프(OFF)되어 전원공급부(30)를 디세이블시켜 동작구동을 위한 전원공급을 하지 않는다. 사용자가 텔레비젼시청 또는 위성방송수신을 위해 스탠바이를 오프(OFF)시키면 npn트랜지스터(Q2)가 온(ON)된다. 따라서 전원공급부(30)가 인에이블되어 pnp트랜지스터 (Q1)가 온(ON)되고 저항들(R4, R5, R6)을 통해 각 부품에 필요한 전원이 인가된다.The state in which only the power cord is connected and the power key is not turned ON is called STAND-BY. When STANDON is ON, the npn transistor Q2 is turned off and the pnp transistor Q1 is turned on. It is also turned off to disable the power supply unit 30 so that power is not supplied for operation. The npn transistor Q2 is turned on when the user turns off standby for television viewing or satellite broadcasting reception. Therefore, the power supply unit 30 is enabled so that the pnp transistor Q1 is turned on and power required for each component is applied through the resistors R4, R5, and R6.
위성방송신호는 영상신호와 음성신호가 같이 실려 있지만, 영상신호는 없고 뛰어난 음질을 갖는 음성신호만을 방송국에서 송신할 때도 있다. 즉 위성방송중 음성신호만이 실린 방송신호를 수신하기 위해서는 스탠바이를 오프(OFF)시키고 출력전원을 모두 온(ON)시켜야 한다. 따라서 사용자는 스피커를 통해 뛰어난 음질의 음성신호를 들을 수 있지만 화면으로는 노이즈가 실린 화면을 시청해야 되며, 또한 원치 않는 화면시청으로 인한 전력방비의 문제점이 있었다.Satellite broadcast signals carry video signals and audio signals together, but there are times when a broadcast station transmits only an audio signal without a video signal and having excellent sound quality. That is, in order to receive a broadcast signal containing only a voice signal during satellite broadcasting, standby must be turned off and all output power must be turned on. Therefore, the user can listen to the voice signal of excellent sound quality through the speaker, but the screen must see the noise-bearing screen, there was also a problem of power consumption due to unwanted screen viewing.
따라서 상술한 문제점을 극복하기 위하여 본 고안의 목적은 위성방송수신가능한 텔레비젼에 있어서 영상수신회로를 구동하기 위한 전원공급수단과 음성수신회로를 구동하기 위한 전원공급수단을 분리하여 스텐바이상태에서 위성방송중 음성신호만이 실린 방송신호를 수신할 때 음성수신회로를 구동시키기 위한 전원만을 인가하는 스탠바이 상태에서 음성신호를 수신할 수 있는 위성방송수신 텔레비젼에서의 전원공급장치를 제공하는데 있다.Accordingly, an object of the present invention is to separate the power supply means for driving an image receiving circuit and the power supply means for driving an audio receiving circuit in a satellite TV capable of receiving a satellite broadcasting in a standby state.
