PURPOSE:To record exactly and automatically only a part which is desired to record of a broadcast by starting a recording by a control signal from a broadcasting station, executing muting, and thereafter, executing control so as to stop the recording. CONSTITUTION:By a start control signal 35, a start pulse 42 is outputted immediately to a mechanism controlling circuit 33 from a time setting circuit 31 as shown in (e), and the mechanism controlling circuit 33 is operated and becomes a recording state. As soon as a program or a musical performance is ended, a time circuit of the time setting circuit 31 is operated by an end control signal 37, and a pulse 43 shown in (d) is outputted to a muting circuit 32. At the same time, a stop pulse 44 shown in (e) is outputted to the mechanism controlling circuit 33. That is to say, after the end control pulse 37, the muting circuit 32 is operated only for the time (t) prescribed in advance, by the pulse 43 shown in (d), and a sound signal and a video signal of a sound recording and picture recording circuit 30 is muted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording and reproducing device that more reliably and automatically records and reproduces broadcasts.

Conventional Structures and Problems Magnetic recording and reproducing devices such as tape recorders and VTRs have become widespread in recent years, and their main use is for recording and reproducing broadcasts.

The procedure for recording a broadcast requires carefully monitoring the broadcast before the program starts, and immediately starting recording as soon as the desired program starts. Also, if you do not continue to monitor the program until the end and stop recording as soon as the program ends, you will end up recording extra programs and using extra tape. Still FM
When recording disc jockeys, etc. for broadcasting, etc., if you want to record only the music and not the commentary, monitor carefully and wait for the commentary to end, then start recording just before the music starts. Also, recording must stop at the same time as the music ends, but it is very difficult to do this completely, and some of the commentary may be recorded before the music starts, or some of the commentary may be recorded after the music ends. It is a very common occurrence for parts to be recorded.

Furthermore, when a timer or the like is used to record the absence, the conditions become even worse. First, the accuracy of the tie and mark is a problem. The start time of recording depends on this accuracy. Also,
Even if the accuracy is good, when the timer is turned on, the operating time of the device from the time when a stain source enters until the start of recording is delayed, resulting in a delay in the start of recording. Furthermore, it is impossible to cut commercials, etc., and it is impossible to stop recording until the timer expires even after the program ends.

In this way, although recording and playing back broadcasts is a very common practice, it is difficult to record only the desired part.
Very difficult work is required.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional problems, and definitely
It is an object of the present invention to provide a magnetic recording and reproducing device equipped with a receiving device that can automatically record and reproduce a target portion of a broadcast.

Structure of the Invention The present invention provides, in addition to audio signals and image signals from a broadcasting station, at the start of a program, at the end of a program, at the start and end of a performance of music, etc. By transmitting a control signal indicating the end, receiving this control signal, and controlling the magnetic recording and reproducing device to start and stop recording of audio signals and image signals according to this control signal, This is a device that can reliably and automatically record only the part of the broadcast that you want to record, while automatically creating a few seconds of unrecorded parts between programs or between performances. It is something that can be done.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a block diagram of a magnetic recording and reproducing apparatus equipped with a receiving device according to an embodiment of the present invention. In FIG. 1, reference numeral 24 indicates a receiving device such as an FM receiver or a television receiver. 23 is its receiving antenna. 25 is a receiving circuit that performs amplification and detection. 26 is an output terminal for audio signals and image signals, and 27 is an output terminal for control signals. 22 is a magnetic recording/reproducing device. 2 is an input terminal for audio signals and image signals, 29 is an input terminal for control signals, 30 is a recording circuit, 31 is a time setting circuit, 32 is a muting circuit, and 33 controls the operation of the magnetic recording/reproducing device. It is a control circuit. 34 is a mechanism for driving a magnetic tape or the like. The output terminal 26 for audio signals and image signals of the receiving device 24 is connected to the input terminal 28 for audio signals and image signals of the magnetic recording and reproducing device 22, and the output terminal 27 for controlling signals of the receiving device 240 is connected to It is connected to the control signal input terminal 29 of the magnetic recording/reproducing device 22 .

The operation of this embodiment configured as described above will be described below. A signal broadcast from a broadcasting station or the like is received by a receiving device 24 from a receiving antenna 23. This signal is amplified and detected by a receiving circuit 25, and the audio signal and image signal are outputted to an output terminal 26, and the control signal is outputted to an output terminal 27, respectively. The start and end control signals input to the input terminal 29 of the magnetic recording/reproducing device are input to the time setting circuit 31. When a start control signal is input to this time setting circuit 31, the signal is directly transmitted to the mechanism control circuit 33, but when an end control signal is input, the time circuit operates and the time setting circuit 31 transmits the signal as it is to the mechanism control circuit 33. The signal is transmitted to the mechanism control circuit 33 with a delay of time t. Further, while this time circuit is operating, a pulse output having a preset time width t is applied to the muting circuit 32. The muting circuit 32 operates to mute the audio signal and image signal of the recording/recording circuit 30 only during the time width of this pulse signal.

The operation of this embodiment will be explained using FIG. 2.

A program is being transmitted as shown in C in FIG. In FIG. 2C, 36 is a start control signal. 36 is a program, a piece of musical performance, or the like. 37 is a control signal for ending the program or music performance of 36. Reference numeral 38 indicates commercials etc. between programs, commentary etc. between one music performance and the next music performance. 39 is a control signal for starting the next program or music performance.

40 is the program or music performance. 41 is its termination control signal. d indicates a pulse output output from the time setting circuit 31 to the muting circuit 32. e indicates a control signal transmitted from the time setting circuit 31 to the mechanism control circuit 33.

f indicates the state recorded on the magnetic tape.

First, the time setting circuit 3 immediately responds to the start control signal 35.
1, a start pulse 42 is outputted to the mechanism control circuit 33 as shown in e. As a result, the mechanism control circuit 33 operates, and the mechanism changes from the REC-PAUSE state to the RFC-PLAY state and enters the recording state. At the same time as the program or music performance 36 ends, the end control signal 3a is activated, and this signal causes the time circuit of the time setting circuit 31 to operate, and outputs the pulse 43 shown in d to the mutijig circuit 32. This pulse 43 is the end control signal 3
Starting after 7, the pulse 43 stops after a preset time t. At the same time, mechanism control circuit 3
3, a stop pulse 44 shown in e is output. That is, after the termination control pulse 37, the muting circuit 32 operates only for a predetermined time t by the pulse 43 shown in d, and mutes the audio signal and image signal of the recording/recording circuit 30. After the time t has elapsed, the mechanism control circuit 33 is activated by the stop pulse 44 shown in e, and the mechanism 34 changes from the REC-PLAY state to the RE.
Switches to C-PAUSE state. As shown in f, after the program or music performance 36 is recorded on the tape, there is a non-recorded portion for a time t, after which the recording time state is reached. The commercials, hemorrhoid theory, etc. 38 shown in C are not recorded, and the start pulse 45 shown in e is applied from the time setting circuit 31 to the mechanism control circuit 33 by the start control signal 39, and the mechanism 34 starts RE again.
From C-PAUSE state to REC-PLAY state,
It enters the recording state. Then, programs, music, etc. 40 are recorded on the tape. By operating as described above, a non-recorded portion of time t (several seconds) is automatically created on the tape between programs or between music.

By configuring the recording medium to run in a state where audio signals and image signals are muted for a certain period of time from the time when the end control signal to stop recording is received, and then enter a recording stop state, On the recording medium, a few seconds of unrecorded parts are automatically created between programs or music, and this allows you to queue or review the program or music you want to play during playback. This unrecorded area will serve as a landmark when searching for the item, making it easier to find it. In addition, some tape recorders, etc., have a function that detects this unrecorded part in the cue state or review state and automatically switches to the playback state. By creating non-recorded portions automatically, the recorded tape can be effectively used as is with a tape recorder equipped with a non-recorded portion detection function.

Effects of the Invention According to the present invention, in addition to audio signals and image signals from a broadcasting station, signals are transmitted at the start and end of a program, at the start and end of a performance of music, etc. By transmitting a control signal representing a signal, receiving the control signal, and controlling the magnetic recording/reproducing device to start and stop recording of an audio signal or an image signal using this control signal,
It is possible to reliably and automatically record only the part of the broadcast that you want to record, without having to constantly carefully monitor and quickly operate the equipment. Furthermore, it is extremely convenient in that a few seconds of unrecorded portions can be automatically created between programs or between pieces of music.
