Abstract

PURPOSE:To record only music continuously by superposing a discrimination signal at a broadcasting station when a broadcast other than a broadcasting of music is delivered, and discriminating this signal and stopping the operation of a sound recorder during the period at a reception side. CONSTITUTION:A broadcasting station when delivering a broadcast other than music such as comments and commercial meassages sends the broadcast together with the superposed discrimination signal of superaudible frequency. The discrimination signal detecting circuit 9 of a tuner 7 detects this discrimination signal at a reception side. A control circuit 11 generates an output as far as a push botton 10 is pressed to operate the temporary stop confirming circuit 12 of a tape recorder 8, stopping sound recording operation temporarily by a temporary stop operating circuit 13. When music broadcasting restarts, the transmission of the discrimination signal is stopped at the broadcasting station and the temporary stopping function is turned off at the reception side and the sound recording restarts. When the push button 10 is not pressed, every broadcast is recorded. Consequently, only music is recorded automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to Which the Invention Pertains] The present invention relates to a selective recording method in which a person listening to a broadcast from a broadcasting station selects and records a desired portion of the broadcast according to the wishes of the listener.

[Description of prior art]

Conventionally, when recording a radio broadcast or the like using an audio device, by pressing the recording button on the tape recorder I, as long as there was a tape, parts deemed unnecessary by the recorder would also be played. A large percentage of people who listen to radio broadcasts are those who record music, but some of these people record only the music and do not think any other commentary is necessary. There are quite a few people.

In other words, the number of audio devices is increasing rapidly, and the number of people purchasing audio devices and listening to music is increasing. These people often use this audio device to record music from 7M broadcasts in their daily lives. However, when trying to blackmail the current 7M broadcast and pressing the record button on the tape recorder, the recorder has to stop recording each time there is a part that he or she does not want to hear. be. Another disadvantage is that it is impossible to record only the desired portion when recording at home.

[Purpose of the invention]

The present invention solves the above-mentioned drawbacks, and aims to provide a selective recording method that can automatically select and record desired broadcast contents by deleting unnecessary parts according to the wishes of the recording person. purpose.

[Summary of the invention]

The present invention provides K
The receiver includes an identification signal detection means for detecting the identification signal and a tape recorder I connected to the receiver when the detection output of the detection means appears. It is characterized by comprising means for stopping.

[Explanation based on examples]

Next, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a block diagram of a selective recording method according to an embodiment of the present invention. In FIG. 1, 1 is an FM broadcasting station, and 2 is a receiver. The FM broadcast station 1 includes a general broadcast transmission circuit 3 and an identification signal transmission path 4. This identification signal sending circuit 4 is
To transmit an identification signal when broadcasting other than music broadcasting is performed. 5 is a transmitting antenna. The receiver 2 also includes a receiving antenna 6 and a tuner 7. A tape recorder 8 is connected to the tuner 7.

FIG. 2 is a detailed block diagram of the tuner 7 and tape recorder 8. In FIG. 2, the tool 7 includes an identification signal detection circuit 9, a selection valve button 10, and a tape recorder stop control circuit 11. The identification signal detection circuit 9 supplies the audio signal of the FM broadcasting station 1 to the audio input terminal of the tape recorder 8 via the audio signal line 9m.
It also detects an identification signal from the FM broadcast j61 and supplies it to the tape recorder stop control circuit 11 via the detection signal line 9b and the selection valve 10. The output of this control circuit 11 is connected to a pause operation circuit 13K via a pause confirmation circuit 12 of the tape recorder 8.

With such a configuration, first, when the FM broadcasting station 1 broadcasts something other than music broadcasting, the identification signal sending circuit 4 sends out an identification signal with a single frequency higher than the audible frequency of the human ear. Next, the identification signal is detected by the identification signal detection circuit 9 of the tuner 7 of the receiver 2 on the listener side, and if the selection valve button 10 is pressed down, the tape recorder stop control circuit 11 stops the tape recorder/8. Operate. When the output signal of the tape recorder stop control circuit 11 is input to the temporary stop confirmation circuit 12k of the tape recorder 8, the conventional temporary stop operation circuit 13 is activated and the tape recorder 8 is temporarily stopped. As a result, in the case of broadcasts other than music broadcasts, the recording state can be canceled by automatically activating the pause function of the tape recorder 8.

Next, when the FM broadcasting station 1 broadcasts music 5, no identification signal is sent out from the identification signal sending circuit 4, so no detection signal appears from the identification signal detection circuit 9 of the receiver 2 on the listener side. Even if the selection valve button 10 is pressed down, no output signal is sent out from the tape recorder stop control circuit 11. Therefore, if the pause operation circuit 13 returns to its original state and the tape recorder 8 is in the recording state, the music broadcast will be recorded. If the selection valve 10 is not pressed down, a detection signal will appear from the sorting signal detection circuit 1l189, and the tape recorder stop control circuit 11 will not operate. The content will be recorded.

〔Effect of the invention〕

As described above, according to the present invention, the 11P broadcasting station is provided with a sending means for adding an identification signal to distinguish between music and non-music broadcasts, and when there is an identification signal, the tuner of the receiver can identify the identification signal. By adding a function that detects the signal and pauses the recording of the tape recorder when this detection output appears, the desired music broadcast can be automatically started by deleting the part that the recorder does not want to record according to his/her preference. It has excellent effects that can be selectively recorded.

In particular, in the case of music broadcasting, since the identification signal is not transmitted, the sound quality of the audio and electronic broadcasting itself does not deteriorate, so there is an advantage that the music recorder will not feel dissatisfied.
