(processing)
Next, processing executed by the notification broadcasting system 1 configured as described above will be described. The processing executed by the notification broadcasting system 1 is roughly divided into notification broadcasting processing executed by the transmission device 70 and reception processing executed by the receiver 20. Hereinafter, these notification broadcast processing and reception processing will be described.

(Processing-Notification broadcast processing)
First, notification broadcast processing will be described. FIG. 4 is a flowchart of the notification broadcast process executed by the transmission device 70 and the notification broadcast system 1 (steps are abbreviated as “S” in the description of each process below). This notification broadcast processing is started when the power of the transmission device 70 is turned on, for example.

  As shown in FIG. 4, when the notification broadcast process is started, the control unit 75 causes the display unit 11 to display a type selection screen for accepting selection of the type of notification broadcast (SA1).

As shown in FIG. 5, the control unit 75 causes the display unit 11 to display buttons indicating, for example, various types of notification broadcasts (“emergency broadcast” and “general broadcast” in FIG. 5).

  Returning to FIG. 4, after the process of SA1, the control unit 75 waits until the type of notification broadcast is selected via the operation unit 71 (SA2, No). When the type of notification broadcast is selected via the operation unit 71 (SA2, Yes), the control unit 75 determines whether the selected type of notification broadcast is emergency broadcast or general broadcast ( SA3).

  As a result, when the type of the notification broadcast selected is emergency broadcast (SA3, emergency), the control unit 75 executes emergency broadcast processing (SA4). On the other hand, when the type of the selected notification broadcast is a general broadcast (SA3, general), the control unit 75 executes a general broadcast process (SA5). After performing the process of SA4 or SA5, the control unit 75 ends the notification broadcast process.

(Processing-Notification broadcast processing-Emergency broadcast processing)
Here, emergency broadcast processing will be described. 6 and 7 are flowcharts of emergency broadcast processing. As shown in FIG. 6, when the emergency broadcast process is started, the control unit 75 transmits information for notification broadcast recorded in the data recording unit 76 (for example, voice information input via the microphone 72, An information selection screen for accepting selection of pre-recorded evacuation instruction information or the like is displayed on the display unit 11 (SB1). FIG. 8 is a diagram illustrating an information selection screen displayed on the display unit 11. As shown in FIG. 8, the control unit 75 displays, for example, a list (“evacuation instruction” and “indoor evacuation instruction” in FIG. 8) indicating each piece of information for notification broadcast recorded in the data recording unit 76. 11 is displayed.

  Returning to FIG. 6, after the process of SB1, the control unit 75 determines whether or not the information for notification broadcast recorded in the data recording unit 76 has been selected via the operation unit 71 (SB2). As a result, when the information for notification broadcast recorded in the data recording unit 76 is selected via the operation unit 71 (SB2, Yes), the control unit 75 reads out the selected information from the data recording unit 76. (SB3).

  When the information for announcement broadcasting recorded in the data recording unit 76 in SB2 is not selected via the operation unit 71 (SB2, No), or after the processing of SB3, the control unit 75 controls the operation unit 71. Then, it is determined whether or not an instruction to repeat the notification broadcast is input (SB4). For example, as shown in FIG. 8, when a “repeat” button is displayed as a repeat broadcast switch on the display unit 11 in SB 1 and this “repeat” button is selected via the operation unit 71, an announcement broadcast is performed. It is determined that an instruction to repeat is input.

  Returning to FIG. 6, when an instruction to repeat the announcement broadcast is input via the operation unit 71 as a result of the determination of SB4 (SB4, Yes), the signal generation unit 75a generates the broadcast start data and generates the generated broadcast data. Broadcast start data is transmitted from the transmitter 73 (SB5). Here, the broadcast start data is data transmitted prior to the information for announcement broadcast, and in the example of FIG. 2, an address / group, a type code, and a start code are included. For example, based on the information recorded in the data recording unit 76, the signal generation unit 75a indicates an address indicating that the emergency broadcast is addressed to all the receivers 20, and indicates that the type of notification broadcast is the emergency broadcast. Broadcast start data including a type code and a start code is generated and transmitted from the transmission unit 73.

(SB6). For example, the signal generation unit 75 a generates notification data based on voice information such as “evacuation instruction” or “indoor evacuation instruction” read from the data recording unit 76 in SB 3, and transmits the notification data from the transmission unit 73.

  Subsequently, the signal generation unit 75a generates a stop code, and transmits the generated stop code from the transmission unit 73 (SB7). For example, the signal generation unit 75 a generates a stop code based on the information recorded in the data recording unit 76 and causes the transmission unit 73 to transmit the stop code.

  Next, the control unit 75 determines whether or not an instruction to end the notification broadcast is input via the operation unit 71 (SB8). For example, when the signal generation unit 75 a transmits the broadcast start data from the transmission unit 73 in SB 5, the control unit 75 displays a “broadcast end” button on the display unit 11, and this “broadcast” is displayed via the operation unit 71. When the “END” button is selected, it is determined that an instruction to end the notification broadcast is input.

  As a result, when an instruction to end the notification broadcast is not input via the operation unit 71 (SB8, No), the process returns to SB5, the signal generation unit 75a generates broadcast start data, and the generated broadcast start Data is transmitted from the transmission unit 73. Thereafter, the process from SB5 to SB8 is repeated until an instruction to end the notification broadcast is input via the operation unit 71.

  In SB2, when a plurality of types of notification broadcast information recorded in the data recording unit 76 are selected and read out from the data recording unit 76 in SB3, the signal generating unit 75a causes the operation unit 71 to operate. In the process of SB6 that is repeatedly executed until an instruction to end the notification broadcast is input through the information for a plurality of types of notification broadcasts selected in SB2 and read from the data recording unit 76 in SB3. One type of information is selected, notification data is generated based on the selected information, and is transmitted from the transmission unit 73. Here, every time the process of SB6 is repeated, the information selected from a plurality of types of notification broadcast information read from the data recording unit 76 is sequentially changed to be recorded in the data recording unit 76. A plurality of types of notification broadcast signals are generated based on part or all of the information for a plurality of types of notification broadcasts, and the generated plurality of types of notification broadcast signals are repeatedly transmitted in a predetermined order. It will be.

  On the other hand, in SB8, when an instruction to end the notification broadcast is input via the operation unit 71 (SB8, Yes), the control unit 75 ends the emergency broadcast process and returns to the main routine.

  In SB4, when the instruction to repeat the notification broadcast is not input via the operation unit 71 (No in SB4), the signal generation unit 75a receives an instruction to start the notification broadcast via the operation unit 71. It is determined whether or not an input has been made (SB9). For example, as shown in FIG. 8, when the “broadcast start” button is displayed as a broadcast switch on the display unit 11 in SB 1 and this “broadcast start” button is selected via the operation unit 71, an announcement is made. It is determined that an instruction to start broadcasting has been input.

  Returning to FIG. 6, as a result of the determination of SB9, when the instruction to start the notification broadcast is not input via the operation unit 71 (SB9, No), the control unit 75 returns to SB2. Thereafter, until an instruction to repeat the notification broadcast is input via the operation unit 71 (SB4, Yes) or an instruction to start the notification broadcast is input via the operation unit 71 (SB9, Yes). The control unit 75 repeats the processes from SB2 to SB4 and SB9.

  On the other hand, when an instruction to start announcement broadcasting is input via the operation unit 71 (SB9, Yes), the signal generation unit 75a generates broadcast start data, and the generated broadcast start data is transmitted from the transmission unit 73. Transmit (SB10).

  Subsequently, the signal generation unit 75a starts accepting voice input by the microphone 72, records the voice accepted by the microphone 72 in the data recording unit 76, and generates notification data based on the inputted voice. The generated notification data is transmitted from the transmission unit 73 (SB11). At this time, the control unit 75 causes the display unit 11 to display a broadcast screen indicating that the voice input via the microphone 72 is being broadcast. FIG. 9 is a diagram illustrating an in-broadcast screen displayed on the display unit 11. As shown in FIG. 9, the control unit 75 displays that the voice input via the microphone 72 is being broadcasted (in FIG. 9, “live broadcasting”), and repeats the broadcast. A “repeat” button for inputting an instruction and a “broadcast end” button for inputting an instruction to end the notification broadcast are displayed on the display unit 11.

  Returning to FIG. 6, the control unit 75 determines whether or not an instruction to repeat the notification broadcast is input via the operation unit 71 (SB12). For example, as shown in FIG. 9, when the “repeat” button is displayed on the display unit 11 in SB 11 and this “repeat” button is selected via the operation unit 71, an instruction to repeat the notification broadcast is given. Is determined to be input.

  Returning to FIG. 6, when an instruction to repeat the announcement broadcast is input via the operation unit 71 as a result of the determination of SB12 (SB12, Yes), the process proceeds to FIG. Is finished, a stop code is generated, and the generated stop code is transmitted from the transmitter 73 (SB13).

  Subsequently, the signal generation unit 75a generates broadcast start data, and transmits the generated broadcast start data from the transmission unit 73 (SB14).

  Subsequently, the signal generation unit 75a generates notification data based on the voice recorded in the data recording unit 76 in SB11, and transmits the generated notification data from the transmission unit 73 (SB15).

  After completing the transmission of the notification data in SB15, the signal generation unit 75a generates a stop code and causes the transmission unit 73 to transmit the generated stop code (SB16).

  Next, the control unit 75 determines whether or not an instruction to end the notification broadcast is input via the operation unit 71 (SB17). For example, as shown in FIG. 9, the “broadcast end” button is displayed on the display unit 11 in SB 11, and when this “broadcast end” button is selected via the operation unit 71, the notification broadcast is ended. It is determined that an instruction to that effect has been input.

  Returning to FIG. 7, when an instruction to end the notification broadcast is input through the operation unit 71 (SB17, Yes), the control unit 75 ends the emergency broadcast process and returns to the main routine.

  On the other hand, when an instruction to end the notification broadcast is not input via the operation unit 71 (SB17, No), the process returns to SB14, the signal generation unit 75a generates broadcast start data, and the generated broadcast start data Is transmitted from the transmission unit 73. Thereafter, the process from SB14 to SB17 is repeated until an instruction to end the notification broadcast is input via the operation unit 71.

  In addition, when one or more types of information for notification broadcasting recorded in the data recording unit 76 are selected in SB2 of FIG. 6 and read from the data recording unit 76 in SB3, the signal generation unit 75a In the process of SB15 that is repeatedly executed until an instruction to end the notification broadcast is input via the operation unit 71, the voice recorded in the data recording unit 76 in SB11 or read from the data recording unit 76 One type of information is selected from the information for notification broadcasting, notification data is generated based on the selected information, and is transmitted from the transmission unit 73. Here, every time the process of SB15 is repeated, information selected from the information recorded in the data recording unit 76 in the SB11 or the information for broadcast notification read out from the data recording unit 76 is sequentially changed. , A plurality of types of notification broadcast signals are generated based on the sound recorded in the data recording unit 76 in SB11 and part or all of the information for notification broadcasting recorded in the data recording unit 76, and the generated A plurality of types of notification broadcast signals will be transmitted repeatedly in a predetermined order.

  Returning to FIG. 6, in SB 12, when the instruction to repeat the notification broadcast is not input via the operation unit 71 (No in SB 12), the control unit 75 ends the notification broadcast via the operation unit 71. It is determined whether or not an instruction is input (SB18). For example, as shown in FIG. 9, the “broadcast end” button is displayed on the display unit 11 in SB 11, and when this “broadcast end” button is selected via the operation unit 71, the notification broadcast is ended. It is determined that an instruction to that effect has been input.

  Returning to FIG. 6, as a result of the determination of SB18, when the instruction to end the notification broadcast is not input via the operation unit 71 (SB18, No), the signal generation unit 75a returns to SB11. Thereafter, in SB12, an instruction to repeat the notification broadcast is input via the operation unit 71 (SB12, Yes), or an instruction to end the notification broadcast is input through the operation unit 71 in SB18 (SB18). , Yes), the processes of SB11, SB12, and SB18 are repeated.

  On the other hand, as a result of the determination of SB18, when an instruction to end the notification broadcast is input via the operation unit 71 (SB18, Yes), the process proceeds to FIG. Is terminated, a stop code is generated, and the generated stop code is transmitted from the transmitter 73 (SB19). Thereafter, the control unit 75 ends the emergency broadcast process and returns to the main routine.

(Processing-Notification broadcast processing-General broadcast processing)
Next, general broadcast processing will be described. FIG. 10 is a flowchart of general broadcast processing. As shown in FIG. 10, when the general broadcast process is started, the control unit 75 causes the display unit 11 to display a range selection screen for accepting an input of a range to which the notification broadcast is addressed (SC1). In this range selection screen, for example, the address of a specific receiver 20, a specific group, or all the receivers 20 can be selected as a notification broadcast destination.

  Next, the signal generation unit 75a waits until an instruction to start notification broadcasting is input while a range to which notification broadcasting is addressed is input via the operation unit 71 (SC2, No). For example, in the range selection screen displayed on the display unit 11 in SC1, the address of a specific receiver 20, a specific group, or all the receivers 20 are selected as notification broadcast destinations via the operation unit 71. If it is, it is determined that the range that is the destination of the notification broadcast has been input. Further, when an “broadcast start” button is displayed on the display unit 11 in SC1 and this “broadcast start” button is selected via the operation unit 71, an instruction to start notification broadcast is input. judge.

  When the range to which the notification broadcast is addressed is input via the operation unit 71 and an instruction to start the notification broadcast is input (SC2, Yes), the signal generation unit 75a generates broadcast start data. Then, the generated broadcast start data is transmitted from the transmitter 73 (SC3). For example, the signal generation unit 75a, based on the information recorded in the data recording unit 76, the address or group of the receiver 20 selected as the general broadcast destination, and the type indicating that the type of notification broadcast is general broadcast. Broadcast start data including a code and a start code is generated and transmitted from the transmission unit 73.

  Returning to FIG. 10, after the process of SC3, the signal generation unit 75a starts accepting voice input by the microphone 72, generates notification data based on the input voice, and transmits the generated notification data to the transmission unit 73. (SC4).

  Next, the control unit 75 determines whether or not an instruction to end the notification broadcast is input via the operation unit 71 (SC5). For example, when the signal generation unit 75 a transmits the broadcast start data from the transmission unit 73 in SC 3, the control unit 75 displays a “broadcast end” button on the display unit 11, and this “broadcast” is displayed via the operation unit 71. When the “END” button is selected, it is determined that an instruction to end the notification broadcast is input.

  As a result, when the instruction to end the notification broadcast is not input via the operation unit 71 (No in SC5), the control unit 75 returns to SC4. Thereafter, the processes of SC4 and SC5 are repeated until an instruction to end the notification broadcast is input via the operation unit 71.

  On the other hand, when an instruction to end the notification broadcast is input via the operation unit 71 (SC5, Yes), the signal generation unit 75a ends the reception of voice input by the microphone 72 and generates a stop code. Then, the generated stop code is transmitted from the transmitter 73 (SC6). Thereafter, the control unit 75 ends the general broadcast process and returns to the main routine.

(Processing-Reception processing)
Finally, the reception process will be described. FIG. 11 is a flowchart of the reception process executed by the receiver 20. This reception process is started, for example, when the power of the receiver 20 is turned on, and is repeatedly executed at a predetermined cycle.

  As shown in FIG. 11, when the reception process is started, the control unit 29 waits until the broadcast start data is received by the reception unit 21 (SD1, No).

  When the broadcast start data is received by the receiving unit 21 (SD1, Yes), the receiver 20 is included in the destination of the notification broadcast signal based on the address or group included in the received broadcast start data. It is determined whether or not (SD2). For example, when the address or group included in the broadcast start data matches the address or group recorded in advance in the data recording unit 30 of the receiver 20, the receiver 20 is included in the address of the notification broadcast signal. It is determined that

  As a result, when the receiver 20 is not included in the address of the notification broadcast signal (SD2, No), the control unit 29 returns to SD1. Thereafter, the broadcast start data is received by the receiving unit 21 (SD1, Yes), and it is determined that the receiver 20 is included in the address of the notification broadcast signal (SD2, Yes). Repeat the process.

  On the other hand, when the receiver 20 is included in the destination of the notification broadcast signal (SD2, Yes), the control unit 29 performs notification broadcast based on the type code included in the broadcast start data received by the reception unit 21. Type (for example, either emergency broadcast or general broadcast) is determined (SD3).

  As a result, when the type of notification broadcast is emergency broadcast (SD3, emergency), the control unit 29 turns on the emergency broadcast indicator lamp 28b (SD4), and causes the volume adjustment unit 24 to set the volume to the maximum (SD5).

  On the other hand, when the type of notification broadcast is general broadcast (SD3, general), the control unit 29 turns on the general broadcast indicator lamp 28c (SD6).

  After the processing of SD5 or SD6, the control unit 29 starts to output the announcement broadcast sound (SD7). That is, the control unit 29 demodulates the notification data included in the notification broadcast signal into audio information by the receiving unit 21, and outputs the audio information from the speaker 26 via the audio switching unit 22, the volume adjustment unit 24, and the amplifier 25. .

  Subsequently, the control unit 29 waits until a stop code is received by the receiving unit 21 (SD8, No). When the stop code is received by the receiving unit 21 (SD8, Yes), the control unit 29 stops the sound output of the notification broadcast (SD9). In this case, the control unit 29 turns off the emergency broadcast indicator lamp 28b or the general broadcast indicator lamp 28c that has been lit, and returns the volume to the volume set by the volume adjustment unit 24. Thereafter, the control unit 29 ends the reception process.

  In the emergency broadcast processing described above, when the notification broadcast signal is continuously and repeatedly transmitted from the transmission device 70, the emergency broadcast sound output from the receiver 20 is repeated by this reception processing. Therefore, even if the user does not perform a specific operation on the receiver 20, the emergency broadcast can be repeatedly output as a sound, and the user can be prevented from missing the emergency broadcast.

  In SD8, even if the stop code was not received by the receiving unit 21, the stop code was not received even after a lapse of a certain time from the start of broadcasting in consideration of the possibility that the stop code could not be received for some reason. In some cases, there is a receiver 20 with a specification that stops receiving the broadcast. If only the notification data is repeatedly transmitted from the transmission device 70 to such a receiver 20, the reception at the receiver 20 is stopped after a certain period of time has elapsed since the start of the broadcast. There is a possibility of missing. However, since the transmission device 70 of the present embodiment repeats transmission of a notification broadcast signal in which the start code and stop code are added to the notification data in the emergency broadcast processing described above, each notification broadcast signal is surely transmitted every time transmission is repeated. The emergency broadcast audio output from the receiver 20 is reliably repeated. When a stop code is not received after the start of broadcasting, a certain time until the reception of the broadcast is stopped is set longer than the time required to broadcast the notification data recorded in the data recording unit 76 once. Thus, it is possible to prevent the emergency broadcast audio output from being interrupted.

(effect)
As described above, according to the embodiment, the data recording unit 76 that records information for notification broadcasting, and the signal generation unit that generates the notification broadcasting signal based on the information for notification broadcasting recorded in the data recording unit 76. 75a and a transmission unit 73 that continuously and repeatedly transmits the notification broadcast signal generated by the signal generation unit 75a, the emergency broadcast can be continued even if the operator of the center apparatus does not repeat the emergency broadcast. Thus, the emergency broadcast can be repeatedly output from the receiver 20 as audio. Thereby, it is possible to prevent the user of the receiver 20 from missing the emergency broadcast while ensuring the safety of the operator of the center device.

  In addition, the data recording unit 76 records the sound that the microphone 72 has received the input, and while the microphone 72 is receiving the input of the sound, the signal generation unit 75a generates the notification broadcast signal based on the input sound. The transmission unit 73 transmits the notification broadcast signal generated by the signal generation unit 75a, and the signal generation unit 75a is recorded in the data recording unit 76 after the microphone 72 finishes receiving the voice input. The notification broadcast signal is generated based on the sound, and the transmission unit 73 continuously transmits the notification broadcast signal generated by the signal generation unit 75a. Therefore, the operator of the center device transmits the contents of the emergency broadcast to the microphone 72. The emergency broadcast can be repeated continuously without having to repeat the emergency broadcast by the operator himself / herself, and the emergency broadcast can be repeatedly output from the receiver 20 by sound. It can be.

  The data recording unit 76 records information for a plurality of types of notification broadcasts, and the signal generation unit 75a is based on part or all of the information for the plurality of types of notification broadcasts recorded in the data recording unit 76. The transmission unit 73 repeatedly transmits the plurality of types of notification broadcast signals generated by the signal generation unit 75a continuously in a predetermined order. However, the emergency broadcast can be repeated continuously without inputting the contents of the emergency broadcast, and the safety of the operator of the center apparatus can be ensured.

  Further, the signal generation unit 75a adds delimiter information (that is, a start code and a stop code) indicating at least one of the head or the end of the information to the information for notification broadcast recorded in the data recording unit 76, Since the notification broadcast signal is generated, each receiver broadcast signal is surely received by the receiver 20 even when the receiver 20 has a specification that stops receiving the broadcast when a certain time has elapsed since the start of one broadcast. Thus, the emergency broadcast can be repeatedly output from the receiver 20 with sound. Thereby, it is possible to prevent the user of the receiver 20 from missing the emergency broadcast while ensuring the safety of the operator of the center device.

[Modifications to Embodiment]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. it can. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above-described contents, and the present invention solves the problems not described above or has the effects not described above. There are also cases where only some of the described problems are solved or only some of the described effects are achieved.

(About notification broadcast processing)
In the above-described embodiment, in the notification broadcast processing of FIGS. 6 and 7, the signal generation unit 75a adds both the start code and the stop code as the delimiter information to the information for notification broadcast recorded in the data recording means. However, one of these start codes or stop codes may be omitted. If the addition of the stop code is omitted, the process of SD8 in the reception process of FIG. 11 is omitted, and when a certain time has elapsed after starting the audio output of the announcement broadcast in SD7, or new broadcast start data is When it is received, the sound output of the notification broadcast so far is stopped (SD9).

  In the above-described embodiment, in the notification broadcast process, a plurality of types of notification broadcast signals are generated based on part or all of the information for the plurality of types of notification broadcasts recorded in the data recording unit 76, and Although it has been described that the plurality of types of notification broadcast signals generated are repeatedly transmitted in a predetermined order, the transmission order of the plurality of types of notification broadcast signals may be specified by the user. For example, the notification broadcast signal generated based on the information for each notification broadcast is repeatedly transmitted in the order in which the information for the notification broadcast recorded in the data recording unit 76 in SB2 is selected via the operation unit 71. You may do it. Alternatively, the order information for specifying the transmission order of the notification broadcast signal is recorded in the data recording unit 76 in association with the information for each notification broadcast, and based on the information for each notification broadcast based on the order information. The transmission order of the notification broadcast signals generated in this way may be determined.

  Further, in the above-described embodiment, when the type of notification broadcast is emergency broadcast, the case where all receivers 20 are addressed is described as an example. However, the number of times the notification broadcast signal is continuously transmitted is described. Accordingly, the receiver 20 or group as the destination may be changed. For example, when the number of transmissions of the notification broadcast signal is the first time, all receivers 20 are addressed, and after the second time, only the receivers 20 belonging to a specific group set in advance are addressed. It may be.

(About reception processing)
In the above-described embodiment, in the reception process of FIG. 11, it has been described that the volume is set to the maximum by the volume adjustment unit 24 when the type of notification broadcast is emergency broadcast. However, the notification broadcast signal is continuously transmitted repeatedly. The sound volume may be changed in accordance with the number of times of being performed. For example, when the signal generation unit 75a transmits the notification broadcast signal continuously and repeatedly from the transmission unit 73, the signal generation unit 75a includes transmission frequency information specifying the number of transmissions of the notification broadcast signal in the broadcast start data. The control unit 29 of the receiver 20 specifies the number of transmissions of the notification broadcast signal received by the reception unit 21 based on the transmission number information included in the broadcast start data received by the reception unit 21, and the type of notification broadcast is emergency broadcast. In this case, when the number of transmissions of the notification broadcast signal is the first time, the volume control unit 24 sets the volume to the maximum. In addition, when the number of emergency broadcast notification broadcast signal transmissions is the second or later, the volume control unit 24 lowers the volume (for example, sets the volume to a medium level). Accordingly, it is possible to prevent the user of the receiver 20 from hearing the emergency broadcast and to prevent the troublesomeness caused by the repeated announcement broadcast at the maximum volume.

  In addition, when the signal generation unit 75a transmits the notification broadcast signal continuously and repeatedly from the transmission unit 73, the broadcast start data may include volume information specifying the volume at the time of audio output. In this case, the control unit 29 of the receiver specifies the volume based on the volume information included in the broadcast start data received by the reception unit 21 and causes the volume adjustment unit 24 to set the specified volume. For example, when the type of notification broadcast is emergency broadcast and the number of transmissions of the notification broadcast signal is the first, the signal generation unit 75a includes the volume information corresponding to the maximum volume in the broadcast start data. Also, when the number of emergency broadcast notification broadcast signal transmissions is the second or later, volume information corresponding to a normal volume (for example, a medium volume) is included in the broadcast start data. Alternatively, every time transmission of the notification broadcast signal is repeated, the volume information corresponding to the maximum volume and the volume information corresponding to the normal volume (for example, medium volume) may be alternately included in the broadcast start data. Good.
