The tuner section 1 is connected to a video detection section 3 and an audio detection demodulation section 4, and the video signal detection section 3 detects the signal amplified and frequency-converted by the tuner 1 into a video signal. The modulated audio signal is detected and converted into an audio signal. At this time, if the audio signal is a multiplexed signal, the audio detection demodulation unit 4 determines the multiplexed signal, and if it is multiplexed, demodulates it, and if it is a stereo broadcast, detects the stereo broadcast. Furthermore, when the audio detection demodulation unit 4 detects multiplexed signals or stereo broadcasting, the audio detection demodulation unit 4 outputs a signal for driving multiplexed signal display or a stereo display device. The detection demodulator 4 includes a multiplex signal display (
or stereo broadcast display) 5 is connected, and the display 5
uses this signal to indicate that it is a multiplex broadcast or stereo broadcast. When the user wants to record this television broadcast, he presses the record button 6. This record button 6 is pressed by the system control unit 7.
The system control unit 7 detects that the record button 6 is pressed and the record button 6 is closed.

Further, the system control section 7 is connected to the video signal recording section 8, the audio signal recording section 9, and the tape drive section 10, and when the system control section 7 detects that the recording button 6 is closed,
A control signal for operating the video signal recording section 8 and audio signal recording section 9 is outputted to operate the recording circuit, and a drive control signal is outputted to the tape drive section 10 to start running the tape 11. Recording is performed by this operation, and to end the recording, press the stop button 12 connected to the system control unit 7.

By pressing and closing the switch, the video tape recorder starts recording again.

In addition, if a reservation is set, the timer section 14 outputs a recording command to the system control section 7 when the reserved start time arrives, and also outputs a signal for receiving the reserved channel to the tuner section 1. do. Furthermore, when the reserved end time is reached, the timer recording is ended by outputting a recording end command to the system control unit A. In this case, it is not possible to cut out unnecessary parts by pausing in the middle of recording.

Problems to be Solved by the Invention However, with the above-mentioned conventional configuration, it is not necessarily possible to turn off only the broadcasts that the user desires. If the broadcast is interrupted during recording, the user operates the pause button 13 or stop button 12 to temporarily interrupt the recording, and then presses the record button 6 again when the broadcast starts. You need to operate the to restart recording. This includes movies and news programs that are broadcast multiplexed, and commercials that are inserted in the middle of music programs that are broadcast in stereo.

The present invention is intended to solve the above-mentioned conventional problems, and an object thereof is to provide a magnetic recording device that can automatically cut unnecessary broadcast portions such as commercials during recording.

Means for Solving the Problems In order to solve the above problems, the magnetic recording device of the present invention is a magnetic recording device that records television broadcasts by having a receiving device for television broadcasts such as audio multiplex broadcasts and stereo broadcasts. , comprising means for determining an identification signal of a broadcast signal indicating that the broadcast signal is an audio multiplex broadcast or a stereo broadcast, and an automatic pause control means for controlling recording of the television broadcast when the identification signal is input; The configuration is such that the recording operation is performed only when it exists.

Operation With the above configuration, the discrimination means discriminates the identification signal of the broadcast signal indicating that it is an audio multiplex broadcast or stereo broadcast, and this discrimination signal is input to the automatic pause control means to control the recording of the television broadcast. Alternatively, the recording operation is performed only when it is a stereo broadcast. That is, if the broadcast is different from multiplex or stereo broadcasting, recording is automatically stopped, and when broadcasting is started again, recording is automatically restarted. Therefore, unnecessary broadcasts such as commercials that are not broadcast in multiplex or stereo between movies and news programs that are multiplexed, or music programs that are broadcast in stereo are automatically cut, and the unnecessary broadcast parts are automatically cut out. This eliminates the need for the user to operate buttons, improving usability.

Embodiment The following describes an embodiment of the present invention, that is, a high-fidelity recording system that can receive audio multiplex broadcasts and stereo audio broadcasts, and automatically pauses the audio multiplex broadcasts or stereo audio broadcasts when they are interrupted midway. An example of a magnetic recording device that can be used will be described with reference to the drawings.

FIG. 1 shows a block diagram of a magnetic recording device according to an embodiment of the present invention, and components having the same functions and effects as those of the conventional example are given the same reference numerals and explanations thereof will be omitted. In FIG. 1, the automatic pause control section 21 is connected to the audio detection demodulation section 4, and the signal of multiplexed signal detection or stereo broadcast detection output from the audio detection tR modulation section 4 is transmitted to the automatic pause control section 21. 21 is also input. That is, an identification signal of a broadcast signal indicating that it is an audio multiplex broadcast or a stereo broadcast is determined, and this determination signal is transmitted to the automatic pause control section 21.
is input. The automatic pause control unit 21 also includes a switch 2 for distinguishing whether automatic pause is to be performed or not.
2 is connected, the system control section 23 is connected, and the switch 22 for performing this temporary stop is closed, and the system control section is activated only when the audio multiplex identification signal or the stereo identification signal is present. It is configured to output a control signal to 23 to cause it to perform a recording operation.

The operation of the above configuration will be described below.

When the automatic pause control section 21 is activated during recording, when the automatic pause switch 22 is closed, the automatic pause control section 21 becomes operable. Here, when a signal is input from the system control unit 23 to the automatic pause control unit 21 and the system control unit 23 determines that the recording mode is in effect, the audio detection demodulation unit 4 identifies that it is a multiplex broadcast. If the signal exists, system control unit 2
3, the automatic pause control unit 21 outputs a control signal to continue recording. If the audio multiplex broadcast is interrupted during recording, such as during a commercial, the audio detection demodulator 4
The signal indicating that the audio multiplex broadcast is also interrupted.

When the automatic pause control section 21 detects this interruption, the automatic pause control section 21 outputs a pause signal to the system control section 23. As a result, the videotape recorder pauses and recording is automatically interrupted. Then, when the audio multiplex broadcast starts again and the audio detection demodulator 4 outputs a signal identifying it as a multiplex broadcast, the system controller 23 sends a control signal to start recording to the automatic pause controller. 21 causes the video tape recorder to resume recording.

Furthermore, if a reservation is set, the timer section 14 outputs a recording command to the system control section 23 when the reserved start time arrives, and also outputs a signal for receiving the reserved channel to the tuner section 1. do. In this case, if the automatic pause switch 22 is closed,
The automatic pause control unit 21 can operate in the same manner as normal recording. When the system control unit determines that the system control unit is in the timer recording mode based on the signal input from the system control unit 23 to the automatic pause control unit 21, there is a signal from the audio detection demodulation unit 4 that identifies multiple broadcasting. If so, the automatic pause control unit 21 outputs a control signal indicating that the system control unit 23 continues timer recording. If the audio multiplex broadcast is interrupted during recording, such as during a commercial, the signal indicating that the audio multiplex broadcast is being broadcast from the audio detection demodulator is also interrupted. When the automatic pause control unit 21 detects this interruption, the automatic pause control unit 2
1 outputs a temporary stop signal to the system control unit 23.

As a result, the videotape recorder pauses and timer recording is automatically interrupted. When the audio multiplex broadcast starts again and the audio detection demodulator 4 outputs a signal identifying it as a multiplex broadcast, the system controller 23 sends a control signal to start timer recording to the automatic pause controller. 21
outputs. This causes the video tape recorder to resume recording.

Then, when the reserved end time comes, the timer unit 14
outputs a recording end command to the system control unit 23 to end the timer recording.

Effects of the Invention As described above, according to the present invention, the identification signal of the broadcast signal indicating that it is audio multiplex broadcasting or stereo broadcasting is determined, and this determination signal is input to the automatic pause control section to perform audio multiplexing or stereo broadcasting. Since it is configured to perform recording operation only when an identification signal is present, it is possible to automatically cut out unnecessary content such as commercials that are not related to the original program content and that the user does not expect. Thus, it is possible to obtain a magnetic recording device that is easy to use and convenient.
