【従来の技術】[Prior art]

これまでの衛星放送受信システム、衛星通信受信システムは図2に示す様にB S又はCSアンテナAで受信した衛星放送又は衛星通信の信号(BS信号又はC S信号)をBSコンバータ又はCSコンバータBによりBSーIF帯域(103 5〜1335MHZ )に又はCSーIF帯域(1380〜1770MHZ )に周 波数変換し、この周波数変換されたBS信号又はCS信号をIF増幅器Cで増幅 して各家庭のBSチューナー又はCSレシーバーDを介してテレビ受像器Eで受 像できるようにしてある。As shown in FIG. 2, the conventional satellite broadcast receiving system and satellite communication receiving system convert a satellite broadcast or satellite communication signal (BS signal or CS signal) received by the BS or CS antenna A into a BS converter or CS converter B. BS over IF band (103 5~1335MH Z) or by frequency conversion into CS over IF band (1380~1770MH Z), each home amplifies the frequency-converted BS signal or CS signal in the IF amplifier C by The image can be received by the television receiver E via the BS tuner or CS receiver D of.

【0003】 図2の受信システムではBS信号又はCS信号をテレビ受像器Eで受像してい てもいなくとも、常にIF増幅器CにAC電源が供給されており、しかもIF増 幅器Cの自動電源供給器(AVR)FからBSコンバータ又はCSコンバータB にDC15Vの電源が供給されるため、電力が無駄に消費されるという問題があ った。In the receiving system of FIG. 2, whether the BS signal or the CS signal is received by the television receiver E, the AC power is always supplied to the IF amplifier C, and the automatic power supply of the IF amplifier C is also provided. Since the power supply of 15V DC is supplied from the supply device (AVR) F to the BS converter or the CS converter B, there is a problem that the power is wasted.

【0004】 この問題を解決するため従来は図3に示す衛星放送受信システム或は衛星通信 受信システムが開発されている。これはテレビE又はBSチューナー或はCSレ シーバーDの電源をONにすると、それらからDC15Vの電圧が出力され、そ れがコイルLを通してBS又はCSコンバーターBに供給されて、自動的にBS 又はCSコンバーターBの電源がONになるようにしたものである。To solve this problem, a satellite broadcast receiving system or a satellite communication receiving system shown in FIG. 3 has been conventionally developed. This is because when the power of the TV E or BS tuner or the CS receiver D is turned on, a voltage of DC15V is output from them, and this is supplied to the BS or CS converter B through the coil L, and the BS or CS is automatically supplied. The power of the CS converter B is turned on.

【考案が解決しようとする課題】[Problems to be solved by the device]

図3の衛星放送受信システム或は衛星通信受信システムでは、BS信号又はC S信号をテレビ受像器Eで受像しないときは、BS又はCSコンバーターBにD C15Vの電圧が供給されないので、その分だけ図2の場合よりも電力消費の無 駄が少なくなるが、BS信号又はCS信号をテレビ受像器Eで受像しないときで もIF増幅器Cには常にAC電源が供給されるので、依然として電力消費の無駄 があるという問題があった。 In the satellite broadcast receiving system or the satellite communication receiving system of FIG. 3, when the BS signal or the CS signal is not received by the television receiver E, the voltage of DC 15V is not supplied to the BS or the CS converter B, so that much. Although the power consumption is less than in the case of FIG. 2, the AC power is always supplied to the IF amplifier C even when the BS signal or the CS signal is not received by the television receiver E, so that the power consumption is still low. There was a problem of waste.

【0006】 本考案の目的はBS又はCSコンバーター及びIF増幅器の電源が、BS信号 又はCS信号の受信時にのみ自動的にONとなり、受信しないときは自動的にO FFになるようにすることにある。An object of the present invention is to automatically turn on a power supply of a BS or CS converter and an IF amplifier only when a BS signal or a CS signal is received, and automatically turn it OFF when it is not received. is there.
