設けるかまたはテレビ受信機を予め電源オンしておく必
要があった。Conventionally, when timer recording satellite broadcast signals etc. from a TV receiver onto a VTR, the TV receiver generally does not have a timer function, so the power supply of the TV receiver is linked with the VTR's timer. In order to turn on the TV, it was necessary to set up a timer or turn on the TV receiver in advance.
従って、テレビ受信機用として別途タイマを必要としタ
イマ設定もVTRとは別にする必要があるという欠点を
有していた。また、テレビ受信機を電源オン状態で待機
させておくことは無駄な電力消費となる。Therefore, it has the disadvantage that a separate timer is required for the television receiver, and the timer setting must be made separately from that of the VTR. Furthermore, leaving the television receiver on standby with the power on results in wasteful power consumption.

。The video signal input/output terminals of the TV receiver and the VTR are connected properly, and the pseudo horizontal synchronization signal generated on the TV receiver side is transmitted to the VTR via the video output terminal of the TV receiver and the input terminal of the VTR. Supply it to When the timer-set VTR is powered on, the pseudo-horizontal synchronizing signal is returned to the television receiver via the video signal output terminal of the VTR and the video signal input terminal of the television receiver. The television receiver side detects the presence of the pseudo-horizontal synchronizing signal, turns on the source section, supplies power to the television signal reproducing section, and outputs a television signal. When the television signal reproducing section starts operating, a video signal is supplied to the VTR instead of the pseudo horizontal synchronizing signal, so that the VTR starts recording.
The switching circuit is switched by the control microcomputer. When the VTR is powered off by the timer setting, there will be no output from the VTR's video signal output terminal. The television receiver detects this no-signal state using a synchronization signal detection circuit, turns off the power supply section, and stops the operation of the television signal reproduction section.

同期信号が発生し第1の切り換え回路6へ伝送される。Next, the operation of the present invention will be explained. The connection between the television receiver and the VTR is as described above, by connecting the video output terminal 9 of the television receiver 1 and the video input terminal 12 of the VTRII, and further connecting the video output terminal 13 of the VTR 11 to the video input terminal of the television receiver 1. and IO respectively. Set the timer on the VTR. The television receiver is in a preheated state. Here, the preheat state refers to a state in which AC power is input, only the control microcomputer 4 and some circuits related thereto are energized, and all other circuits are powered off. The second switching circuit 7 is shown in 7. When switched to the 7□ side, the function according to the present invention is activated, and when switched to the 7□ side, the function is inactive, and the function is similar to that of a normal television receiver. Now, the second switching circuit 7 is set to 7. When it is turned to the side, a pseudo horizontal synchronizing signal is generated by the control microcomputer 4 and transmitted to the first switching circuit 6.

受信機lの同期信号検出回路5へ伝送される。Here, the pseudo horizontal synchronization signal is a signal equivalent to the original horizontal synchronization signal generated by the control microcomputer 4. The first switching circuit 6 is set to the 6 side by the control microcomputer 4 when the second switching circuit 7 is set to the 7I side and a preheat state is entered. Therefore, the pseudo-horizontal synchronizing signal is transmitted to V T via the first switching circuit 6 and the video output terminal 9.
It is input to the video input terminal 12 of R11. If the VTR 11 for which the timer is set is in a power-off state, the buffer amplifier 14 and the like are also inactive, and no signal is output to the video output terminal 13. Here, if the VTRII is powered on according to the timer setting, the buffer amplifier 14
etc. are also brought into operation, and the pseudo-horizontal synchronizing signal input to the video input terminal 12 is output to the video output terminal 13. This output path is output to the video output terminal 13 via a buffer amplifier 14 and a switching circuit 16 as shown. The recording/playback switching circuit 16 is switched to the 161 side during recording, and is switched to the 16□ side during recording/playback. Incidentally, during recording and reproduction, a recording and reproduction signal is output from the recording/reproduction block 15. This pseudo-horizontal synchronizing signal is transmitted to the synchronizing signal detection circuit 5 of the television receiver I according to the connection described above.

レビ信号を再生する。The synchronization signal detection circuit 5 detects the presence of a synchronization signal and outputs the signal to the control microcomputer 4. The control microcomputer 4 powers on the power supply unit 2 based on the signal. The television signal reproducing section 3 operates with the power from the power supply section 2 that is turned on and reproduces the television signal.

The television signal reproducing section 3 is controlled and set using the control signal. On the other hand, the first switching circuit 6 is switched to the 6□ side to which the video signal output is connected by a control signal from the control microcomputer 4 (manual input to the terminal 64). This result V
A video signal is input to TR11 instead of the pseudo-horizontal synchronization signal, recording is started, and the video signal is output to output terminal 13.

ともに第1の切り換え回路6を再び61側へ設定する。The synchronization signal detection circuit 5 detects the synchronization signal in this video signal and keeps the power supply section 2 in the power-on state. When recording is finished and the VTR 11 is powered off again according to the timer setting of the VTR, no signal is output to the output terminal 13. Therefore, the synchronizing signal detection circuit 5 detects the "absence" of the synchronizing signal and transmits it to the control microcomputer 4. In response to this signal, the control microcomputer 4 turns off the power supply unit 2 and sets the first switching circuit 6 to the 61 side again.

れ録画と同時にモニタすることができる。The television signal reproducing section 3 stops operating when the power supply section 2 is turned off. The first switching circuit 6 is 6. As a result of this setting, the pseudo-horizontal synchronizing signal is again supplied to the input terminal 12 of the VTRs 1, 1. In other words, the television receiver 1 returns to the preheat state. After this, if the VTR 11 is set for timer recording, the above operation is repeated. When the second switching circuit 7 is set to the 7□ side, the operation is similar to that of a normal television receiver, and the video signal from the video output terminal 13 of the VTR 11 is processed by the signal processing circuit 8 and recorded. can be monitored at the same time.

ころが大きい。As explained above, according to the present invention, when timer recording a TV signal from a TV receiver on a VTR, conventionally the TV receiver side uses its own timer or the TV receiver is turned on. When I tried to deal with this problem by putting the pseudo-horizontal synchronization signal generated by the preheated TV receiver into the VTR, the pseudo-horizontal synchronization signal that was output to the video output terminal when the VTR's timer was turned on was sent to the TV. The receiver side detects this and starts the operation of the TV signal reproducing section to output the TV signal to the VTR, so there is no need to turn on the timer or the TV receiver in advance, and the TV receiver can operate the VTR. By using the timer function, it has the effect of having its own timer function, which greatly contributes to improving the functionality of the television receiver and saving power.
