【実施例】以下、本発明の一実施例について図面を参照しながら説明する。 EXAMPLES Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention.

【0011】図1において、11は同期信号検出回路、 [0011] In FIG. 1, 11 is a synchronization signal detection circuit,
12は文字放送復調回路、13は切換回路、14は映像信号からの同期信号検波回路、15は判別信号発生回路、16は同期信号検波後の同期信号からの同期信号検出回路、17は同期信号検出回路からの検出信号のスイッチ回路である。 12 teletext demodulation circuit, 13 a switching circuit, the synchronizing signal detection circuit from the video signal 14, 15 determination signal generating circuit, a synchronization signal detection circuit from the sync signal after 16 synchronous signal detection, 17 synchronization signal a switch circuit of the detection signal from the detection circuit.

【0012】以上のように構成されたテレビジョン受信機の同期信号検出回路について、以下その動作を説明する。 [0012] The synchronization signal detection circuit configured television receiver as described above, operation is described below.

【0013】文字放送以外の一般放送受信時又はビデオ機器再生時は、切り替え回路23は(b)側に閉じ、映像信号は切換回路13を経て同期信号検波回路14に供給され検波された同期信号は偏向回路に出力される。 [0013] During the general broadcast reception during or video equipment other than the character broadcast reproduction, the switching circuit 23 (b) closed side, the video signal is supplied to the synchronizing signal detection circuit 14 through the switching circuit 13 detected synchronization signal is output to the deflection circuit. 同期信号検出回路11は従来と同様に映像信号から同期信号の検出を行なう。 Synchronization signal detection circuit 11 performs detection of the sync signal from the video signal as in the prior art. 同期信号検出回路16は同期信号検波後の同期信号から同期信号の検出を行なう。 Synchronization signal detection circuit 16 performs detection of the synchronization signal from the synchronization signal after the synchronization signal detection. ここで、 here,
文字放送受信時の文字のちらつき防止のため飛び越し走査を停止させるインタ−レス停止信号が文字放送復調回路12より偏向回路へ供給される。 Inter stops for interlaced scanning of teletext receiving time character of preventing flicker - less stop signal is supplied from the teletext demodulator circuit 12 to the deflection circuit. スイッチ回路17は文字信号復調回路12からのインタ−レス停止信号によって開く構成であり、文字放送以外の一般放送受信時には閉じており、同期信号検出回路11からの検出信号と同期信号検出回路16からの検出信号は判別信号発生回路15に供給される。 The switch circuit 17 is inter from the character signal demodulation circuit 12 - a configuration that opens by less stop signal, is closed at the time of general broadcast reception other than the character broadcast, from the detection signal and the synchronizing signal detecting circuit 16 from the synchronization signal detection circuit 11 the detection signal is supplied to the discrimination signal generating circuit 15. 判別信号発生回路15は各々の検出信号によって開閉するスイッチ回路で構成され、同期信号が検出されて検出信号が供給されると閉じる構成としている。 Determination signal generating circuit 15 is a switch circuit for opening and closing the respective detection signals, the synchronization signal is configured to close when the detection signal is detected is supplied. よって同期信号検出回路11、信号同期信号検出回路16双方からの検出信号が供給されない場合のみ同期信号無しの判別信号が出力される。 Therefore the synchronization signal detection circuit 11, the detection signal from the signal synchronization signal detection circuit 16 both discrimination signal without only synchronous signal if not supplied is output. この事によって、従来の同期信号検出回路11を同期信号検波後の同期信号検出回路16が補い、判別感度の向上が図れる。 This fact, compensate for the conventional sync signal detection circuit 11 sync signal detection circuit 16 after the synchronization signal detection, thereby improving the determination sensitivity.

【0014】また、文字信号復調時には、切換回路13 Further, when a character signal demodulation, the switching circuit 13
は文字放送復調回路12側(a)に閉じ、文字放送復調回路12より出力された文字信号が、同期信号検波回路14に供給され検波された同期信号は偏向回路に出力される。 Closes the teletext demodulation circuit 12 side (a), the character signal outputted from the character broadcast demodulating circuit 12, the synchronization signal detected is supplied to the synchronizing signal detection circuit 14 is output to the deflection circuit. 文字放送復調回路12にはメモリ−機能が付加されているため映像信号の有無に無関係に文字信号が出力され、同期信号検波後の同期信号検出回路16は文字放送受信時には常に同期信号の有となり従来同様の同期信号検出が行なえない。 The teletext demodulation circuit 12 Memory - function independently of the character signal is output to the presence or absence of the video signal for is added, the synchronization signal detection circuit 16 after the synchronization signal detection becomes a chromatic always sync signal at the time of teletext receiving can not be performed is conventional similar synchronization signal detection. ここで、文字信号復調回路12からのインタ−レス停止信号によって開く構成のスイッチ回路17によって同期信号検出回路16からの検出信号の判別信号発生回路15回路への供給を停止させる。 Here, inter from a character signal demodulation circuit 12 - to stop the supply to the determination signal generating circuit of the detection signal from the synchronization signal detection circuit 16 by the configuration of the switch circuit 17 to open the less stop signal 15 circuit. よって、文字放送受信時には従来同様の機能を保つ事が出来る事となる。 Thus, at the time of teletext receiving a be able to keep the conventional similar function. なお、本実施例では同期信号検波後の同期信号検出回路の検出信号をスイッチ回路で開く構成としたが、同期信号検出回路への同期信号供給を停止させる事でも可能である。 In the present embodiment has a configuration that opens a detection signal of the synchronizing signal detecting circuit after the synchronization signal detected by the switch circuit, it is possible by stopping the synchronizing signal supplied to the synchronizing signal detecting circuit.
