  Next, as shown in FIG. 2, the FM complementary broadcast data includes AM broadcast station data provided corresponding to all AM broadcast stations in the whole country, and each AM broadcast station data includes a corresponding AM broadcast. The broadcast station name of the station, the AM broadcast frequency representing the broadcast frequency within the AM broadcast frequency band used by the corresponding AM broadcast station for AM broadcast, and the AM broadcast and simulcast of the corresponding AM broadcast station are related ( An FM supplementary broadcast frequency representing a broadcast frequency within the FM broadcast frequency band used for the FM supplementary broadcast which is an FM broadcast having the same broadcast program content is registered.

  Now, referring back to FIG. 1, the control device 3 accepts a user operation via the input device 6 with an appropriate user interface using the display device 4, and controls the operation of the navigation device 2 and the radio reception device 1. The screen for displaying the video output from the navigation device 2 and the information output from the radio receiver 1 is displayed on the display device 4, and the sound output from the navigation device 2 or the radio receiver 1 is output from the audio output device 5. Perform processing.

  For example, the control device 3 displays a predetermined FM broadcast channel selection reception screen created using the FM channel selection candidate list on the display device 4, receives selection of FM broadcast from the user via the input device 6, and selects The controller 14 of the radio receiving apparatus 1 is instructed to receive and output the FM broadcast frequency. On the other hand, the controller 14 of the radio receiving device 1 that has received the instruction sets the FM front end 121 of the FM receiver 12 by setting the FM broadcast frequency for which the reception output is instructed to receive the FM broadcast of the frequency and the FM. Broadcast audio output is started, and the selector 13 causes the controller 3 to output audio output by the FM receiver 12. Then, the control device 3 causes the audio output device 5 to output the audio of the FM broadcast selected by the user output from the radio reception device 1 to the speaker 8 as described above.

  Similarly, the control device 3 displays a predetermined AM broadcast channel selection reception screen created using the AM channel selection candidate list on the display device 4, and selects AM broadcasts from the user via the input device 6. The controller 14 of the radio receiver 1 is instructed to receive and output the broadcast frequency of the AM broadcast that has been accepted and selected. On the other hand, the controller 14 of the radio receiving apparatus 1 that has received the instruction sets the AM broadcast end frequency of the AM broadcast for which the reception output is instructed to the AM front end 111 of the AM receiving unit 11, thereby receiving the AM broadcast of the frequency and the AM. Broadcast audio output is started, and the selector 13 causes the control device 3 to output audio output from the AM receiver 11. Then, the control device 3 causes the audio output device 5 to output the audio of the AM broadcast selected by the user output from the radio reception device 1 to the speaker 8 as described above.

  Now, during the period when the AM broadcast sound received by the AM receiver 11 of the radio receiver 1 is output from the speaker 8, that is, during the period when the AM broadcast is received and output, the control device 3 is FM. Perform complementary broadcast search processing.

FIG. 3 shows the procedure of FM supplementary broadcast search processing.
As shown in the figure, the control device 3 determines whether or not there is an FM supplement broadcast of AM broadcast being received by the radio reception device 1 in the FM supplement broadcast search process. The determination is made with reference to the AM broadcast station data of the AM broadcast station (step 302). The AM broadcast station data of the AM broadcast station of the AM broadcast being received is the AM broadcast station data in which the broadcast frequency of the AM broadcast being received is registered as the AM broadcast frequency, or the broadcast station of the AM broadcast being received. It is obtained as AM broadcast station data in which the name is registered. Further, when the broadcast frequency registered as the FM complementary broadcast frequency exists in the AM broadcast station data of the AM broadcast station of the AM broadcast being received, the FM complementary broadcast of the AM broadcast being received exists.

  If there is no FM supplementary broadcast of the AM broadcast being received by the radio receiver 1 (step 302), the FM supplementary broadcast presence flag is cleared (step 312), and the AM broadcast received by the radio receiver 1 is cleared. Waiting for the broadcast frequency to be changed (step 314), the process returns to step 302.

  On the other hand, if FM supplementary broadcast of the AM broadcast being received exists (step 302), each broadcast frequency of each FM supplemental broadcast that exists, that is, the AM broadcast station data of the AM broadcast station of the AM broadcast being received is included. Each broadcast frequency registered as an FM complementary broadcast frequency is scanned to check the reception state of the FM complementary broadcast at each broadcast frequency (step 304).

Here, scanning of each frequency of each existing FM supplementary broadcast is performed as follows.
That is, the control device 3 instructs the controller 14 of the radio reception device 1 to check the reception quality of the search frequency by sequentially setting each broadcast frequency of the FM supplementary broadcast of the AM broadcast being received one by one as the search frequency. The controller 14 instructed to check the reception quality of the FM broadcast at the search frequency sets the search frequency in the FM front end 121 of the FM reception unit 12 and causes the FM reception unit 12 to receive the FM broadcast at the search frequency. A value related to the reception quality of the search frequency such as the received electric field strength of the search frequency and the S / N ratio of the received signal of the search frequency is acquired from the FM front end 121 or the FM demodulator 122 of the FM reception unit 12 as a check result. Notify the control device 3. Then, the control device 3 calculates the reception state of the search frequency from the check result notified from the radio reception device 1.

  Now, if the reception state of each broadcast frequency of the FM supplementary broadcast of the AM broadcast being received is examined as described above (step 304), the broadcast frequency of the FM supplementary broadcast of the AM broadcast being received is determined. It is checked whether there is a broadcast frequency with a good reception state (step 306). If there is no broadcast frequency, the FM supplement broadcast flag is cleared (step 316), and the processing returns to step 302.

  On the other hand, when there is a frequency with a good reception state among the broadcast frequencies of the FM supplementary broadcast of the AM broadcast being received (step 306), the broadcast frequency with the best reception state among the existing frequencies is used. The FM complementary broadcast frequency is set (step 308).

Then, the FM supplement broadcast flag is set (step 310), and the process returns to step 302.
The FM supplementary broadcast search process performed by the control device 3 during AM broadcast reception output has been described above.
According to such FM supplementary broadcast search processing, during the period in which FM supplementary broadcast of AM broadcast being received and output can be received, the FM supplementary broadcast presence flag is set and FM supplement of AM broadcast being received and output is complemented. The broadcast frequency of the FM supplementary broadcast that can be received best among the broadcasts is set to the current FM supplementary broadcast frequency. On the other hand, during the period in which the FM supplementary broadcast of AM broadcast being received and output cannot be received, the FM supplemental broadcast presence flag is cleared.

Next, FM supplementary broadcast switching processing performed by the control device 3 will be described.
Here, the FM supplementary broadcast switching process is performed when the output of the AM broadcast or FM broadcast sound received by the AM receiver 11 or the FM receiver 12 of the radio receiver 1 from the speaker 8 is started, that is, by the user. It is activated and executed when use of the radio receiver 1 is started.

FIG. 4 shows the procedure of the FM complementary broadcast switching process.
As shown in the figure, in the FM supplementary broadcast switching process, the control device 3 is currently receiving and outputting the AM broadcast (step 402) and is currently receiving and outputting the FM supplemental broadcast. (Step 404) is examined. Here, the state in which the AM broadcast is being received and output is a state in which the AM broadcast sound received by the AM receiving unit 11 of the radio receiving device 1 is being output from the speaker 8, and the FM complementary broadcast is received. The output state is a state in which the sound of the FM complementary broadcast received by the FM receiving unit 12 of the radio reception device 1 is output from the speaker 8.

  If the AM broadcast is currently being received and output (step 402), it is checked whether the FM complementary broadcast presence flag is set (step 406). If not set, the process returns to step 402. .

  On the other hand, if the FM supplement broadcast presence flag is set (step 406), whether the reception state of the AM broadcast being received and output has deteriorated (step 408), and the user's FM with respect to the input device 6 is determined. It is checked whether or not a complementary broadcast switching operation has occurred (step 410). If neither has occurred, the process returns to step 402.

  On the other hand, when either the deterioration of the reception state of the AM broadcast being received and output (step 408) or the user's FM supplementary broadcast switching operation (step 410) on the input device 6 has occurred, the current FM supplementary broadcast By instructing the controller 14 of the radio reception apparatus 1 to receive and output FM broadcast at the broadcast frequency set to the frequency, the broadcast to be received and output is switched to the FM supplement broadcast of AM broadcast that has been received and output up to the present time ( Step 412).

  Here, the reception state of the AM broadcast being received and output is calculated by acquiring the value related to the reception quality detected by the AM receiver 11 via the controller 14 of the radio receiver 1.

Details of the FM supplementary broadcast switching operation of the user whose occurrence is detected in step 410 will be described later.
If the broadcast to be received and output is switched to the FM complementary broadcast as described above, the processing returns to step 402.
On the other hand, if the FM supplementary broadcast is currently being received and output (step 404), the following processing is performed.
Here, whether or not the FM supplementary broadcast is currently being received and output is whether the broadcast to be received and output has been changed after the broadcast received and output in step 412 is switched to the FM complementary broadcast. The broadcast frequency of the FM broadcast being received that is received by the FM receiver 12 of the radio receiver 1 is registered as the FM complementary broadcast frequency in any AM broadcast station data of the FM complementary broadcast data. A determination can be made based on whether or not the frequency.

  If the FM complementary broadcast is currently being received and output (step 404), whether the reception state of the FM complementary broadcast being received and output has deteriorated (step 414), and the input device 6 Whether or not the user's simul AM broadcast switching operation has occurred (step 416). If neither has occurred, the process returns to step 402.

Note that the simultaneous AM broadcast switching operation of the user whose occurrence is detected in step 416 will be described later.
On the other hand, when either the deterioration of the reception state of the FM complementary broadcast during reception output (step 414) or the user's simultaneous AM broadcast switching operation (step 416) with respect to the input device 6 occurs, the reception output is performed. Instructing the controller 14 of the radio receiver 1 to receive and output AM broadcasts at the broadcast frequency of AM broadcasts that are related to FM complementary broadcasts and simulcasts, the received and output broadcasts have been received and output up to the present time. The FM supplementary broadcast is switched to the AM broadcast having a relationship between the FM supplemental broadcast and the simulcast (step 418), and the process returns to step 402.

  Here, the reception state of the FM complementary broadcast being received and output is calculated by acquiring the value related to the reception quality detected by the FM reception unit 12 via the controller 14 of the radio reception apparatus 1.

  In addition, the broadcast frequency of the FM broadcast that is in the relationship between the FM complementary broadcast that is received and output and the simulcast is registered as the FM complementary broadcast frequency. It can be obtained as an AM broadcast frequency registered in the existing AM broadcast station data. If there are a plurality of AM broadcast frequencies registered in the AM broadcast station data, in step 418, the reception status of each existing AM broadcast frequency is checked, and the AM broadcast frequency with the best reception status is received. The broadcast to be output may be switched.

  If the broadcast to be received and output has not been changed after switching the broadcast to be received and output in step 412 described above to FM supplementary broadcast, in step 418, before the FM complementary broadcast being received and output. The broadcast to be received and output may be switched to the broadcast frequency of the AM broadcast that has been received and output.

  Further, in step 418, when there is no AM broadcast with a good reception state among the AM broadcasts in the relationship between the FM complementary broadcast and the simulcast being received and output, the broadcast to be received and output is switched to the AM broadcast. It is good also as a process which returns to step 402 as it is, without performing.

The FM supplementary broadcast switching process performed by the control device 3 has been described above.
Hereinafter, the user's FM complementary broadcast switching operation for detecting occurrence in step 410 of the FM complementary broadcast switching process and the user's simultaneous AM broadcast switching operation for detecting occurrence in step 416 will be described.

The present invention can be similarly applied to any system including the receiving device 1 or the radio receiving device 1.

  Further, in this case, when applied to the radio receiving device 1 having a small display device 4 or a system including the radio receiving device 1, it is possible to use FM supplementary broadcasting of AM broadcasting being received and output. The display shown and the reception of the FM supplementary broadcast switching operation by the user may be performed as shown in FIGS.

  That is, a plurality of hard keys 53 are provided below the screen of the display device 4, and the identification of the operation accepted by the hard keys 53 below the hard keys 53 is displayed at a position above each hard key 53 at the bottom of the screen of the display device 4. To do.

  If the FM supplement broadcast presence flag is not set during AM broadcast reception output for one hard key 53a, the operation with the hard key 53a is not accepted. Further, when the FM supplementary broadcast presence flag is set during the reception and output of the AM broadcast, the FM supplementary broadcast can be used by displaying 54 such as “FM supplement” on the hard key 53a. In response to the operation of the hard key 53a, the user's FM complementary broadcast switching operation is accepted. Further, in this case, while receiving and outputting the FM supplementary broadcast, “AM switching” or the like is displayed on the one hard key 53a described above, and the user performs an operation according to the operation of the hard key 53. Accept simultaneous AM broadcast switching operation.

  Alternatively, a hard key for accepting FM supplementary broadcast switching operation and an indicator such as an LED indicating whether the hard key 53 is valid / invalid by turning on / off are provided, and the FM supplementary broadcast presence flag is set during AM broadcast reception output. Only when the indicator is on, the indicator may be turned on and the operation of the hard key may be accepted as an FM complementary broadcast switching operation. In this case, for example, the user's reception of the simultaneous AM broadcast switching operation is received by operating an FM complementary broadcast switching operation reception hard key during reception and output of the FM complementary broadcast.

  In addition, although shown above about the case where AM broadcast and FM supplementary broadcast are received with the radio receiver 1, AM broadcast in this embodiment is changed into the 1st type broadcast which is broadcast of arbitrary 1st broadcast standards. The FM broadcast is a second type broadcast that is a broadcast of a second broadcast standard that is an arbitrary broadcast standard different from the first broadcast standard, and the FM supplementary broadcast is a first type broadcast that is in a relationship between the first type broadcast and the simulcast. It can also be applied by replacing it with a simultaneous type 2 broadcast that is a type 2 broadcast.
