Description
送信機１０は、上記したように受信機３０から送信要求信号が送られてきている間、放送波再送信部１２が動作状態となり、壁面アンテナ端子１から放送波入力端子１１に入力されるテレビ放送波を高周波増幅器１３で増幅し、再送信アンテナ１７から再送信する。受信機３０は、送信機１０の再送信アンテナ１７から出力される再送信波を受信アンテナ３１で受信し、切替スイッチ３２及びＲＦ／ＤＣ分離器３３を介して放送波出力端子３４より出力する。この放送波出力端子３４から出力される再送信波は、同軸ケーブル４２を介してテレビ受像機４１へ送られる。 In the transmitter 10, as described above, while the transmission request signal is transmitted from the receiver 30, the broadcast wave retransmitting unit 12 is in an operating state, and the TV input from the wall surface antenna terminal 1 to the broadcast wave input terminal 11 is set. The broadcast wave is amplified by the high frequency amplifier 13 and retransmitted from the retransmission antenna 17. The receiver 30 receives the retransmission wave output from the retransmission antenna 17 of the transmitter 10 by the reception antenna 31 and outputs it from the broadcast wave output terminal 34 via the changeover switch 32 and the RF / DC separator 33. The retransmitted wave output from the broadcast wave output terminal 34 is sent to the television receiver 41 via the coaxial cable 42.
また、上記実施例では、受信機３０から一定周期の間欠的な送信要求信号を出力する場合について示したが、テレビ受像機４１から動作電源が供給されている間、連続する波形の送信要求信号を出力するようにしてもよい。この場合、送信機１０は受信機３０から送られてくる送信要求信号を受信している間、送信要求検出部２０の制御により再送信制御スイッチ２２をＯＮして放送波再送信部１２に動作電源を供給し、上記送信要求信号の送信が停止された際に再送信制御スイッチ２２をＯＦＦして放送波再送信部１２の動作を停止する。上記のように送信要求信号を連続波形とした場合には、送信要求検出部２０に送信タイマを設けることなく、再送信制御スイッチ２２及び放送波切替スイッチ１６を制御することが可能である。 In the above embodiment, the case where an intermittent transmission request signal with a fixed period is output from the receiver 30 has been described. However, while the operation power is supplied from the television receiver 41, the transmission request signal having a continuous waveform. May be output. In this case, the transmitter 10 operates the broadcast wave retransmission unit 12 by turning on the retransmission control switch 22 under the control of the transmission request detection unit 20 while receiving the transmission request signal transmitted from the receiver 30. When power is supplied and the transmission of the transmission request signal is stopped, the retransmission control switch 22 is turned off to stop the operation of the broadcast wave retransmission unit 12. When the transmission request signal has a continuous waveform as described above, it is possible to control the retransmission control switch 22 and the broadcast wave changeover switch 16 without providing a transmission timer in the transmission request detection unit 20 .
