Abstract

PURPOSE:To record exactly and automatically only a part which is desired to record of a broadcast by controlling the start and stop of recording by a control signal from a broadcasting station. CONSTITUTION:Immediately before the next program 16 is started, a program start control signal 15 is transmitted and received. This signal is applied to a controlling circuit 12, by which a mechanism 13 for driving a magnetic tape is switched to an REC-PLAY state, the magnetic tape starts to run,and recording is started. When an end control signal 17 is transmitted and received as soon as the program 16 is ended, it is operated so that the mechanism 13 is switched to an REC-PAUSE state. As a result, the running of the magnetic tape is stopped, and the recording is stopped. In this way, only a part extending from the time when the start control signal is transmitted from a broadcasting station to the time when the end control signal is transmitted is recorded automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording and reproducing apparatus that can record and reproduce broadcasts more reliably and automatically.

Conventional configurations and their problems In recent years, magnetic recording and reproducing devices such as tape recorders and VTRs have become widespread, and their main use is to record and reproduce broadcasts. The procedure for recording a broadcast is to carefully monitor the broadcast before the program starts, and to start 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. Also, when recording disc jockeys etc. for FM broadcasts, etc., if you want to record only the music and not the commentary etc., carefully monitor the commentary and wait for the commentary to end, then record just before the music starts. However, it is very difficult to do this completely, and some commentary may be recorded before the music starts, and the recording must be stopped at the same time as the music ends. It is very common for parts of a video 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 timer becomes a problem.

The start time of recording depends on this accuracy. Further, even if the accuracy is good, the operating time of the device from the time when a stain source enters the timer until the start of recording is short, resulting in a delay in the start of recording. Furthermore, commercial cunts, etc. are not possible, and furthermore, it is impossible to stop recording until the timer expires even after the broadcast ends. Although recording and reproducing broadcasts is a common practice, recording only the desired portion requires extremely difficult work.

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/reproducing device to stop recording after starting recording of the audio signal or image signal according to this control signal. Second, it is possible to reliably and automatically record only the part of the broadcast that you want to record.

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 Figure 1,
1 is a broadcasting station, and 2 is its transmitting antenna. 3 is a receiving antenna. 4 is a receiving device such as an FM receiver or a television receiver.

6 is a receiving circuit that performs amplification and detection. 6 is a sound child, 9
is an input terminal for control signals. 11 is a recording circuit,
12 is a control circuit that controls the operation of the magnetic recording/reproducing device. 13 is a mechanism for driving a magnetic tape or the like.

Then, an output terminal 6 for audio signals and image signals of the receiving device 4
The input terminal 8 for audio signals and image signals of the magnetic recording/reproducing device 10 is connected to the input terminal 8, and the output terminal 7 for the control signal of the receiving device 4 (+Y) is connected to the input terminal 8 for the control signal of the magnetic recording/reproducing device 1o. is connected to input terminal 9 of.

The operation of this embodiment configured as above will be described below with reference to FIG. 2.

First, a program is transmitted from the broadcasting station 1 and the transmitting antenna 2 in FIG. 1 as shown in FIG. 2 (,). In FIG. 2(a), 16 is the program to be recorded, and 14 is the previous program or commercial. 18 is a commercial or the next program after the program to be recorded, and 015 is a start control signal for the program 16 to be recorded. 17 is an end control signal for the program 16 to be recorded. The passage of time is plotted from left to right in FIG.

Through this process, as shown in FIG. 1, the signal is broadcast from the transmitting antenna 2 and received by the receiving device 4 from the receiving antenna 3. This signal is amplified and detected by the receiving circuit 6, and an audio signal, an image signal, and a control signal are output.

The audio signal and the image signal are separately output to the output terminal 6, and the control signal is output to the output terminal 7. The signals are then input to the respective input terminals 8 and 9 of the magnetic recording/reproducing apparatus 1o.

The magnetic recording/reproducing device 10 has already been powered on and
And the recording (recording) timing status is so-called REC-PAUS,
It is in E state. Program 14 is currently being transmitted and received. When this program 14 ends and immediately before the next program 16 begins, a program start control signal 15 is transmitted and received. This signal is amplified, detected, and demodulated by the receiving circuit 5, outputted to the control signal output terminal 7, and inputted to the control signal input terminal 9 of the magnetic recording/reproducing apparatus 1o.
This changes the mechanism 13 that drives the magnetic tape from the RFC=PAUSE state to the RFC-PLA state.
The state is switched to Y and the magnetic tape starts running. At this time, the audio signal and the image signal have already been input to the recording/recording circuit 11 from the input terminal 8 and have reached the recording head of the mechanism 13, and recording starts at the same time as the magnetic tape is running.

Simultaneously with the end of the program 16, when the end control signal 17 is transmitted and received as shown in FIG. The output terminal 7 for the control signal of the magnetic recording/reproducing device 1o
The mechanism 13 is changed from the REC-PLAY state to the RFC-PA input terminal 9.
It operates to switch to the USE state. As a result, the magnetic tape stops running and recording stops. With the above operation, only the period from when the broadcast station transmits the start control signal to when the end control signal is transmitted is automatically recorded.

2) shows an example of a program such as a music disc jockey. (in Fig. 2) shows a state in which a signal is being transmitted from a broadcasting station. 19 is an explanation etc. before the music performance begins. After that, the start control signal 2o is 89, and the performance 21 starts immediately after that. 0. Immediately after the performance 21 ends, the end control signal 22 is activated, and then the explanation 23 starts. Thereafter, a start control signal 24 is activated just before the fire music performance 25 begins, and an end control signal 26 is generated at the same time as the element 25 ends.

After that, explanation 27 begins again. When broadcast in this way, the operation of this embodiment is as follows in Explanation 19: REC-PAU
In the SE state, by the start control signal of 20, RFC-PL
AY, and the end control signal 22 causes the REC-PA to start again.
USE and start 7 control signal 24 again REC
- PLAY.

Then, the end control signal 26 causes the operation to go to fiREc-PAUSE.As a result, only performances 21 and 25 are recorded, and the portions of explanatory examples 19, 23, and 27 are not recorded at all.

Effects of the Invention According to the present invention, in addition to audio signals and image signals from a broadcasting station, each signal is By transmitting a control signal indicating start and end, receiving the control signal, and controlling the magnetic recording/reproducing device to start or stop recording of an audio signal or image signal using this control signal. 4. You can always carefully monitor and quickly operate the equipment. 4. You can reliably and automatically record only the part of the broadcast that you want to record, without having to do it right now. 0. You also want to record even if you are not present. As long as you put the magnetic recording/reproducing device into the REC-PAUSE state a little before the beginning of the section,
It also has the advantage of being able to automatically record the desired portion without having to touch it at all, and reducing the use of excess magnetic tape to the minimum necessary.
