DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video / audio signal recording apparatus for recording a video / audio signal in conjunction with the operation of an external device.

[0002]

2. Description of the Related Art Video tape recorders (hereinafter, referred to as VTRs) for recording video and audio signals on a magnetic tape are widely used. This VTR generally has a tuner for receiving analog terrestrial broadcasts and analog BS broadcasts, and programs transmitted by these broadcasts can be recorded alone.

[0003] On the other hand, in recent years, CS digital broadcasting and BS digital broadcasting have become widespread. To record programs transmitted by these broadcasting, a CS broadcasting or BS broadcasting receiver is connected to a VTR. The video and audio signals output from these receivers are recorded through the external input of the VTR.

[0004] When timer-recording a program transmitted by a CS broadcast or a BS broadcast by a VTR, it is necessary to make a reservation setting for both the receiver and the VTR, and the operation is complicated. . So, some VT
R detects whether a signal is input to the external input terminal and starts recording at the timing when the video / audio signal starts to be detected, so that the timer reservation operation on the VTR side can be omitted. Recording was stopped when the signal was no longer detected.

[0005]

However, when recording is started or stopped simply based on whether or not a video / audio signal comes in, the user turns off the power of the receiver regardless of the timer reservation. There is a problem that the usability is not good because the VTR starts recording just by turning it on.

[0006] In recent years, a receiver having a terminal for connecting a remote control transmitter has appeared, so that a VTR can be remote-controlled by infrared light or the like in conjunction with a timer reservation operation of the receiver. I have. FIG. 4 is a diagram showing a system configuration in a case where recording of a VTR is interlocked by remote control as described above, and a video signal input terminal V of a VTR 400 is shown.
in receives a video signal from the video signal output terminal Vout of the receiver 500, and an audio signal input terminal Ain of the VTR 400 receives an audio signal from the audio signal output terminal Aout of the receiver 500. are doing.

[0007] A remote control transmitter 501 is connected to a control signal output terminal CTLout of the receiver 500 via a cable CV.

F. Control of recording start and stop.

However, in the case of the system as shown in FIG. 4, if there is an obstacle between the remote control transmitter 501 and the remote control receiver 401, the remote control receiver 401 cannot receive the remote control signal. If any obstacle exists during the timer reservation operation of the receiver 500, normal recording cannot be performed.

[0009] Further, since the remote control signal for turning on the power of the VTR 400 and the remote control signal for turning off the VTR 400 are the same signal, if the power supply of the VTR 400 is turned on immediately before the timer reservation operation, the timer reservation operation starts. , VTR
There is a problem that the power of the 400 is turned off, and normal recording cannot be performed. There is also a problem that normal recording cannot be performed unless the VTR 400 is set to the external input state in advance when the power of the VTR 400 is turned on.

[0010] Further, the VTR 400 is simply a remote control receiver 4
Since it is only operated by a remote control signal coming in through the 01, no warning is displayed even if the cassette is forgotten to be inserted, and there is a possibility that the recording may fail due to the forgetting to insert the cassette.

The present invention has been made in view of these problems, and provides a video / audio signal recording apparatus capable of easily and reliably recording a program in conjunction with an external device reserved for timer recording. The purpose is to:

Reference numeral 11 denotes a cassette presence / absence detecting unit for detecting whether or not a cassette accommodating the recording medium 20 is inserted into the video / audio signal recording apparatus, and 12 detects a recording prevention control hole provided in the cassette. It is a hole detection unit.

As shown in the figure, the CPU 4 can receive the output of each of the carrier removing unit 3, the remote control receiving unit 14, the operating unit 13, the cassette presence / absence detecting unit 11, the cassette hole detecting unit 12, and the synchronizing signal detecting unit 8. Connected with these configurations,
The video signal switching unit 6, the video signal recording unit 7, the audio signal switching unit 9, and the audio signal recording unit 10 are also connected to these components so that they can be controlled. Although not shown here, the present video / audio signal recording apparatus includes a recording medium 20.
There is provided a mechanism for inserting and ejecting a cassette in which is stored.

Next, the operation of the video / audio signal recording apparatus according to the present invention will be described. First, the user selects a mode according to the connected device when performing recording in conjunction with the external device. Here, the present video / audio signal recording apparatus executes the recording based on the link reservation mode in which the recording is executed based on the remote control signal input through the control signal input terminal CTLin and the synchronization signal detected by the synchronization signal detection unit 8. And an incoming call reservation mode.

When recording is performed in conjunction with an apparatus having a control signal output terminal CTLout, such as the first receiver 200 shown in FIG. 1, the link reservation mode is selected while the second reservation mode shown in FIG. When the recording is executed in conjunction with an apparatus having no control signal output terminal CTLout, such as the second receiver 300, the incoming call reservation mode is selected.

Hereinafter, the control signal output terminal CTLout
An operation in the link reservation mode in which recording is performed in conjunction with an external device having the function will be described. For example, the user sets the link reservation mode on the menu screen of the video / audio signal recording apparatus, and further presses a predetermined button on the operation unit 13 to put the video / audio signal recording apparatus in a standby state.

When the video / audio signal recording device is in a standby state, the cassette presence / absence detection unit 11 detects that a cassette is not inserted, or the cassette hole detection unit 12 prevents recording. When the control hole is detected, a warning is displayed on a display unit (not shown) provided on the front surface of the video / audio signal recording apparatus. In this standby state, the power-on instruction and the cassette ejection instruction from the operation unit 13 are not accepted.
It is necessary to press a predetermined button that has been shifted to the standby state for a predetermined time.

Then, in such a standby state, when a remote control signal comes in via the control signal input terminal CTLin, the signal detection section 1 detects this remote control signal. Then, the output of the signal detecting unit 1 is output via the H / L inverting unit 2 and further passes through the carrier removing unit 3 so that the CPU
3 is supplied.

FIG. 3 shows a control signal input terminal C
FIG. 3 is a diagram showing the configuration from TLin to CPU 4 in detail. As shown in the figure, the signal detecting section 1 is composed of resistors R1 and R2 and a transistor T1, and the H / L inverting section 2 has a resistor R1.
3, the carrier removing unit 3 includes a voltage source Vc, a resistor R6, and a capacitor C1.

The resistors R5 and R7 are provided to limit the flowing current and protect each element. Each element shown in FIG. 3 has R1, R2, R3, and R4 = 10 k.
Ω, R5 = 100Ω, R6 = 47 kΩ, R7 = 1 kΩ,
It is assumed that C1 = 10 mF and Vc = 5V.

First, a remote control signal coming into the control signal input terminal CTLin will be described. This remote control signal is a signal for turning on the LED in the remote control transmitter 501 shown in FIG. Is transmitted by being superimposed on a predetermined carrier through a cable having a signal line and a second signal line. As a method of transmitting this signal, there are a method of fixing the potential of the negative electrode and changing the potential of the positive electrode, and a method of fixing the potential of the positive electrode and changing the potential of the negative electrode. The present video / audio signal recording apparatus supports both of these transmission methods.

The transistor T1 is turned on when a remote control signal is input to the positive or negative electrode of the control signal input terminal CTLin in conjunction with the timer reservation operation of the external device.
State and the collector and emitter are connected.

For example, in a method of transmitting a remote control signal by fixing the potential of the negative electrode and changing the potential of the positive electrode, the negative electrode is always 0 V,
By changing the voltage to about 3 V, a remote control signal is transmitted. On the other hand, in the method of transmitting the remote control signal by fixing the potential of the + electrode and changing the potential of the − electrode, the + electrode is always 5 V, and the − electrode is set to, for example, 2 to 3 V.
The remote control signal is transmitted by changing the distance.

Therefore, it is not possible to cope with both transmission methods by detecting only the change in the voltage at one of the electrodes. However, in this video / audio signal recording apparatus, the potential difference between the + electrode and the − electrode is detected. Therefore, the transistor T1 is turned on in any of the above-mentioned methods,
The signal can be detected.

The emitter of the transistor T1 and H / L
Since the inversion unit 2 is connected, when the transistor T1 is turned on, the base voltage of the transistor T2 becomes H, and the transistor T2 is turned on. As described above, when a potential difference occurs between the + electrode and the − electrode, the transistor T2 is turned on, and the collector and the emitter are connected, so that the voltage at the port (not shown) of the CPU 4 decreases, and a signal is detected. . On the other hand, if there is no potential difference between the + electrode and the − electrode, the transistor T
Since both 1 and T2 are OFF, the collector and the emitter are disconnected, and a high voltage is supplied to the port of the CPU 4.

As described above, the remote control signal is superimposed on a predetermined carrier and transmitted. However, since the high frequency component is removed in the carrier removing section, only the net signal is supplied to the CPU 4. The CPU 4 shown here
The H / L inverting unit 2 inverts H and L when the voltage supplied to the port is 0 or a value close to this, in order to detect this as a signal. When a CPU of a type that detects the supplied voltage as a signal is used, the H / L inverting unit 2 is not required.

Then, the CPU detects the remote control signal supplied in this manner.
, A recording start command, a recording stop command, and a command to turn off the power are sequentially transmitted. As described above, the command to turn on the power and the power to the
The command to be F is the same command.

First, when a command to turn on the power is transmitted immediately before the start of the timer-reserved program by the external device, the CPU 4 receiving the command turns on the power of the apparatus, and subsequently the video signal switching unit. 6 and the audio signal switching unit 9 to select signals from the first video signal input terminal V1in and the first audio signal input terminal A1in.

At the start time of the timer-reserved program, a recording start command is transmitted.
Controls the video signal recording unit 7 and the audio signal recording unit 10 to start recording the video signal and the audio signal on the recording medium 20. Note that the video / audio signal recording apparatus does not accept an instruction such as power-off via the operation unit 13 during execution of recording in the link reservation mode.

Then, when the end time of the timer-reserved program comes, a recording stop command and a command to turn off the power are transmitted, and the CPU 4 controls the video signal recording unit 7 and the audio signal recording unit 10 to After stopping the recording of the signal and the audio signal on the recording medium 20, the power supply of the apparatus is turned off.
Change to F. In this way, the recording linked to the timer reservation operation of the external device in the link reservation mode is completed.

As described above, the video / audio signal recording apparatus according to the present invention directly receives a remote control signal from an external device,
Since the recording operation is performed, even when the power of the external device is turned on regardless of the timer reservation, the recording is not erroneously performed, and the recording linked to the timer reservation operation of the external device can be reliably performed. .

A warning is displayed when a cassette is forgotten to be inserted or a cassette having a recording prevention control hole, that is, a cassette for which recording is prohibited is inserted, so that the video / audio signal recording apparatus starts recording. It is possible to confirm whether or not it is in a state where it can be performed.

Prior to the start of recording of a program, the first video signal input terminal V1in and the first audio signal input terminal A1i.
n, the power-on command is received and the power is turned off
Since the input is automatically switched after setting to N, it is possible to prevent a situation in which a program received by the tuner 5 or a program from another input terminal is erroneously recorded.

Here, the power of the apparatus is turned on in response to the reception of the command to turn on the power from the external device.
At the same time, an example in which signals from the first video signal input terminal V1in and the first audio signal input terminal A1in are selected has been described. However, the present invention is not limited to this. For example, a predetermined button is pressed on the operation unit 13. At this time, first, the first video signal input terminal V
1in and the signal from the first audio signal input terminal A1in are selected, and then the video and audio signal recording device is set to a standby state, and when the power of the device is turned on, control is performed so as to simply return to the state before the standby state. You may.

On the other hand, the control signal output terminal CTLout
When recording is performed in conjunction with a timer reservation operation of an external device that does not have the function, a user sets a call reservation mode on a menu screen and performs recording. In the incoming call reservation mode, first, the user presses a predetermined button on the operation unit 13 to put the video signal recording / reproducing apparatus in a standby state, but the CPU 4 sets the video signal switching unit 6 immediately before shifting to the standby state. And by controlling the audio signal switching unit 9,
Switching is performed so that signals from the first video signal input terminal V1in and the first audio signal input terminal A1in are selectively output.

At the start time of the timer-reserved program, a video signal comes in through the first video signal input terminal V1in, and the video signal switching section 6 selectively outputs this.
Accordingly, the synchronization signal detecting section 8 detects the synchronization signal included in the video signal, and when the synchronization signal is detected,
The synchronization signal detector 8 outputs a detection signal to the CPU 4.

When the detection signal is output from the synchronization signal detection unit 8, the CPU 4 controls the video signal recording unit 7 and the audio signal recording unit 10 to record the video signal and the audio signal on the recording medium 20. To start. During recording, the power is turned off via the operation unit 13 as in the link reservation mode.
Etc. are not accepted.

Thereafter, when the end time of the timer-reserved program comes, the synchronization signal is no longer detected by the synchronization signal detection unit 8, so that the CPU 4 controls the video signal recording unit 7 and the audio signal recording unit 10 to The recording of the signal and the audio signal on the recording medium 20 is stopped, and then the power supply of the apparatus is turned off.
Set to FF. In this way, the recording linked to the timer reservation operation of the external device in the incoming call reservation mode is completed.

As described above, in the video / audio signal recording apparatus according to the present invention, since the link reservation mode and the incoming call reservation mode can be switched and used, the control signal output terminal CTL
Both an external device with out and an external device without this terminal can perform recording linked to the timer reservation operation, and the external device can control the control signal output terminal CTLou.
When t is provided, recording can be performed more reliably.

When the external device operates irrespective of timer reservation, it can not only prevent the accidental start of recording, but also ensure that it is linked to the timer reservation operation of the external device. It is possible to perform an effective recording.

[0053] According to the second or third aspect of the present invention, a remote control signal output from an external device and indicating that the power is on,
Alternatively, it is possible to prevent a situation in which a program or the like received by the tuner is erroneously recorded because the selection output unit is controlled to selectively output a signal from an external device in response to the setting of the standby state. It works.

According to the fourth aspect of the present invention, when it is not detected that a recording medium is inserted in a state where the standby state is set, a warning display is performed. It is possible to check whether or not the signal recording device is ready to start recording.

Further, according to the invention of claim 5, the remote control signal is detected by detecting the potential difference between the first signal line and the second signal line in the cable connected to the external device.
