3 has an L-MSK modulator 144.

Here, the stereo modulator 131 receives the L audio signal and the R audio signal, and receives the L + R signal and the L-R signal.
Generate a signal. On the other hand, the encoding units 141 and 141 encode program information, and the program information here is FM radio audio broadcasting which is a main broadcast such as a music title of a music being broadcast, a singer name, and a request telephone number. It consists of complementary information to be supplemented and independent information such as weather forecast and traffic information that is independent of the FM radio.

In this case, as shown in FIG. 4, these program information can be provided in each broadcasting station at a maximum of 256 programs, and desired programs such as news (0

As a result, multiplexed information consisting of characters is multiplexed with the main audio signal such as music and transmitted. Here, as one program information of the broadcasting station, the broadcasting station name as shown in FIG. In addition, menu data # 1 to # including song title, performance time, program start time, and program end time
Up to n are transmitted in the same manner as the weather forecast and traffic information described above, and as the complementary information (multiple information) of the voice information (music information), the title of the music information as shown in FIG. That is, the song name, or the song name, start code, and end code of the song information as shown in FIG. 7B, or the song name and playing time of the song information as shown in FIG. Has become.

Next, the operation of the embodiment configured as described above will be described. Now, as complementary information of voice information, FIG.
Considering the case where only the song title of the song information is transmitted as shown in (a), in this case, the flowchart shown in FIG. 7 is executed.

First, in step 701, a song title information setting process is performed. In this case, from the desired broadcasting station,
When the menu data of 1 to #n are received, these menu data are loaded into the reception data memory 7. Then, the menu data of the received data memory 7 is displayed on the display unit 5, and while scrolling this display, desired song titles are sequentially designated so that the total playing time does not exceed the recordable time of the recording unit 10. Then, the song name, playing time, program start time, and program end time of each menu data specified here are the search start time, search end time, broadcast station name, song name, and recording time of the search data memory 6 shown in FIG. Will be written in each. In this case, the playing time of the menu data shown in FIG. 5 corresponds to the recording time of the search data memory 6, the program start time corresponds to the search start time of the search data memory 6, and the program end time corresponds to the search end time of the search data memory 6. are doing.

In this case, when a broadcast station is different and a music title whose program time overlaps is to be designated, the fact is notified or the designation of the music title is prohibited. The data to be written in the search start time, the search end time, the broadcast station name, the song title, and the recording time in the search data memory 6 may be directly input by key operation on the key input unit 4.

Next, at step 702, it is judged whether the time of the clock section 8 has reached the search start time of the search data memory 6, that is, the program start time. If NO here, this state is held. On the other hand, when the program start time comes, YE
If S, in step 703, the receiving broadcast station is set.

In this case, by setting the reception frequency corresponding to the broadcast station name set corresponding to the search start time in the search data memory 6 and tuning the FM tuner 102 via the reception control unit 11. Select the receiving broadcast station. The correspondence table with the reception frequency corresponding to the broadcasting station name is assumed to be built in the control unit 3 in advance.

Next, in step 704, the L-MSK demodulator 201 and the error correction decoder 202 separate the information multiplexed in the FM broadcast wave to receive the multiplexed information.

In this case, as the multiplex information, only the song title is received together with the song information as the voice information as shown in FIG. 6A. Then, in step 705, it is compared with the music title written in the search data memory 6 corresponding to the search time, and in the next step 706, it is determined whether the music titles match. Here, if the song titles do not match and the answer is NO, the routine proceeds to step 707, where it is determined whether the time of the clock unit 8 has reached the search end time of the search data memory 6. Then, if it is NO instead of the search end time, the procedure returns to step 704 to receive the multiplex information and repeat the above-mentioned operation. If the search end time has been reached and YES, then the procedure returns to step 702. , Will wait for the next search start time.

This is because there is a possibility that a match cannot be detected in step 706 because the received radio wave is weak, so the search end time is set even if all the music information of the music title designated in the same search time is not recorded. This is because it is possible that

On the other hand, in step 706, if the song names match and the answer is YES, the timer 9 is started in step 708, and in step 709, the recording section 1 for the song information is started.
Recording at 0 starts. Then, in step 710,
The content of the timer 9 is the recording time of the search data memory 6,
In other words, it is determined whether or not the playing time of the song has elapsed, and the recording time has not yet elapsed, and if NO, recording is further continued.

Then, after the recording time has elapsed, step 7
When the answer is YES in step 10, the process proceeds to step 711 to end the recording, and the recording completion flag corresponding to the song title is set in the search data memory 6. And step 71
In step 2, it is determined whether or not there is remaining set music title information designated by the same search time (same program). In this case, the remaining set music title information is determined by whether or not there is a recording completion flag not set.

If no record completion flag is found in the same search time and the result is NO, the music title comparison process is terminated and the process proceeds to step 713, where the search start time which has not yet been reached is the search data memory 6 It is determined whether or not it is written in. Then, if it is not written here and is NO, it is considered that all the music information of the music name designated in advance has been recorded, and the processing is ended. On the other hand, in step 712, if the recording completion flag is not found and the result is YES, the process returns to step 704, the multiplex information is received again, and the above-described operation is repeated.

If it is written and YES in step 713, the process returns to step 702 to wait for the next search start time. Therefore, in this way, based on the menu data sent in advance as multiplex information,
While designating desired song titles in order, the corresponding search start time, search end time, broadcast station name, and recording time are stored in the search data memory 6, and when the search start time is detected, the corresponding received broadcast is received. After setting the station, wait until the song name information sent as complementary information of the voice information matches the corresponding song name in the search data memory 6 and record the song from the corresponding recording time in the search data memory 6. I'm trying to do. As a result, if only the song title is known, the desired song can be recorded. Also, since only the specified song can be recorded, the tape can be saved. Furthermore, since only desired songs can be recorded in sequence on the master tape, there is no need for editing, and deterioration of sound quality due to dubbing can be prevented.

It should be noted that the menu data need not be displayed as in the present embodiment, but only the song title or only the song title and performance time may be displayed. Further, the playing time of the designated song name is added to display the total playing time, and when the total playing time exceeds the recordable time of the recording section 10, a notification to that effect and prohibition of designation of the song name Etc. may be performed.

Next, as complementary information of the voice information, FIG.
Considering the case where the music title, the start code, and the end code are transmitted as shown in (b), in this case, the flowchart shown in FIG. 8 is executed.

In this case, the operations up to step 706 are the same as those in the flowchart of FIG. Then, in step 706, if the song names match and the answer is YES, step 7
At 13, it is determined whether the recording start code is detected.

Here, the recording start code is not detected and N
If it remains O, this state is maintained. On the other hand, when the recording start code is detected and YES is determined, step 714
Then, the recording of the song information by the recording unit 10 is started.
Then, in step 715, it is determined whether the recording end code is detected. Here, the recording end code is not detected,
If NO, continue recording.

Thereafter, in step 715, the recording end code is detected, and if YES, the process proceeds to step 711 to end the recording, and thereafter, the same operation as the flowchart described in FIG. 7 is executed.

Therefore, in this way, by using the start code and end code sent together with the song name as the supplementary information of the voice information, only the desired song can be confirmed while confirming the beginning and end of the song. Since recording can be performed and there is no influence due to the error of the timer 9, more accurate recording can be realized. Further, by using the start code and the end code, it is not necessary to set the recording time in the search data memory 6 described above, so that it is not necessary to take in or transmit the performance time information in the menu data.

Further, since it is not necessary to measure the playing time, it is not necessary to provide the timer 9. Next, as shown in FIG. 6 (c), as the supplementary information of the voice information, consider the case where the music title and the playing time are transmitted.
The flowchart shown in is executed.

In this case, the operations up to step 706 are the same as those in the flowchart of FIG. Then, in step 706, if the song names match and the answer is YES, step 7
At 16, the timer 9 is started at the same time when the recording section 10 starts recording the song information. Next, Step 71
In step 7, the performance time information sent together with the song title is fetched, and in step 718, it is judged whether or not the content of the timer 9 has passed the performance time fetched in the previous step 717. Here, if the recording time has not elapsed and if NO, this recording state is held. On the other hand, when the recording time has passed and YES is obtained in step 718, step 7
In step 11, the recording is ended, and thereafter, the same operation as the flowchart described in FIG. 7 is executed.

Therefore, even in this case, by using the playing time information sent together with the song name as the supplementary information of the voice information, only the desired song is recorded while checking the playing time of the song. Therefore, accurate recording can be realized in this case as well. Also in this case, it is possible to eliminate the need for capturing or transmitting the performance time information in the monument data.

In this embodiment, the case of recording a song has been described, but the present invention can be applied to a case of recording traffic information or weather forecast. The present invention is not limited to the above-described embodiments, and can be appropriately modified and implemented within the scope of the invention. For example, in the above-mentioned embodiments, the case of recording is described consistently, but it can be applied to the case of voice output.
