Description

  The present invention relates to an emergency disaster information receiver, and more particularly to an emergency disaster information receiver for receiving and notifying an earthquake early warning.

  An emergency disaster information receiver for receiving and notifying disaster information transmitted from a transmitting station when an emergency such as an earthquake occurs has been presented. For example, a disaster prevention radio (radio disaster management radio receiver with radio) or emergency notification receiver that detects emergency chime warning chime sound from radio sound during standby and outputs radio sound from the speaker when detected Has been.

  Further, Patent Document 1 discloses a disaster prevention radio receiver that emits the contents of broadcast from a speaker when receiving an emergency earthquake warning in radio broadcast or when receiving a disaster prevention radio broadcast. This disaster prevention radio receiver detects that an earthquake early warning has been issued by detecting a chime sound transmitted together with the earthquake early warning.

  On the other hand, in terrestrial television broadcasting, emergency earthquake bulletins are transmitted in a form that is superimposed on the video and audio being broadcast. However, a delay occurs in encoding on the transmitter side, decoding on the receiver side, and the like, and there is a problem in quick reportability. In order to solve this problem, a method of transmitting emergency earthquake warning information using an AC (Auxiliary Channel) signal for transmitting additional information has been added to the ARIB (STD-B31) standard. According to this, the earthquake early warning is segment no. It is transmitted using 0 AC signal (carrier).

  For example, in Patent Document 2, when an earthquake early warning is issued from a broadcasting station using an AC signal, the fact is displayed on the display unit and emergency disaster information for generating an alarm sound according to a user setting is disclosed. A receiving device is disclosed. In addition, upon receiving the earthquake early warning, this emergency disaster information receiving device outputs a control signal for safely operating an external device such as an elevator from an output terminal, and also transmits an emergency broadcast to an external television receiving device. A command signal for receiving (power-on command, emergency broadcast channel selection command) is transmitted from the remote control transmitter.

  However, the method of detecting the chime sound of the earthquake early warning from the sound of the radio broadcast like the disaster prevention radio receiver described in Patent Document 1 is not related to the earthquake early warning because the analog sound is analyzed. Even in the case of sound, when a change in sound of a specific frequency is similar to that of a chime sound, a false detection may occur. Also, nationwide broadcasts also detect earthquake early warnings about areas that are not related to where you live (for example, if you live in Tokyo, you can also detect earthquake early warnings for Hokkaido). On the other hand, it may be confused as to whether it is an earthquake early warning for your area. And if such things continue, there is a risk that the attention to emergency earthquake warnings that are really relevant will be reduced.

  In addition, when the emergency earthquake bulletin is missed, it is difficult to confirm the contents of the emergency disaster information receiving device described in Patent Document 2 unless the emergency earthquake bulletin is sent again in the subsequent broadcast. .

The Japan Meteorological Agency announces information related to the earthquake early warning when there is a predicted earthquake occurrence area greater than the predetermined maximum seismic intensity. A transmission station such as a television transmits the emergency earthquake information 800 included in the segment of the one-segment broadcasting signal based on this information.

  The AC carrier in the segment includes information on a region where a predetermined seismic intensity or more is predicted as AC signal information 803. Details will be described later with reference to FIG.

Information included in AC signal information 803 and 904 is defined in ARIB STD-B31, and other information can be included as appropriate.

  Hereinafter, each piece of information included in the AC signal information will be described in accordance with the format of ARIB STD-B31. The configuration identification 1001 is information indicating whether the AC signal information is transmission of earthquake motion warning information. Since the AC signal information itself is used for transmitting additional information in addition to the earthquake motion warning, it is determined by this configuration identification 1001 whether the AC signal information is information related to an earthquake. The start / end flag 1002 is information indicating the start or end of transmission of earthquake motion warning information. The signal identification 1003 is information indicating the type of detailed earthquake motion warning information. The current time 1004 is current time information at which earthquake motion warning information is transmitted, and the number of seconds elapsed from the reference year / month / day / hour / minute / second is represented by a binary number. Further, the earthquake motion information 1006 is information indicating a warning motion warning target area, which is an area where an earthquake of a predetermined seismic intensity or higher is predicted, which is transmitted when the page type 1005 is “0”. In the present embodiment, a case where the page type 1005 is “0” will be described.

The seismic motion information 1006 indicating the alarm target area of the seismic motion warning is assigned to the 56th to 111th bits of the AC signal information 803 and 904, and one area of information is assigned to each bit. When the bit value is “1”, it indicates an area that does not include the alarm target area for the earthquake motion warning, and when the bit value is “0”, the area includes the alarm target area for the earthquake motion alarm. For example, when “B ₆₉ ” (hereinafter, “B” represents a bit value and a subscript represents a bit number) is “0”, it represents that Saitama Prefecture is included in the alarm target area of the earthquake motion warning.

  Next, processing at power-on will be described. When the power is turned on, the control unit 207 performs initial setting of the one-segment receiving unit 202, initial setting of the signal processing unit 203, initial setting of the display unit 101, and the like. Thereafter, the user sets the one-seg reception channel and the area to be installed by using the operation buttons (channel selection buttons) 105, 106 and the like.

  Specifically, the user inputs the name of the area where the emergency disaster information receiver 100 is installed from the input unit 103 in accordance with the area name character data 602 displayed on the display unit 101. As the area name, for example, a prefecture name is input. The control unit 207 refers to the conversion table 401, obtains an assigned bit number 601 corresponding to the input region name, and stores the obtained assigned bit number 601 in the set region assigned bit number table 404 in the control storage unit 208. .

  The user operates the input unit 103 to select a one-segment broadcasting station to be received (for example, a broadcasting station with a good radio wave condition or a broadcasting station corresponding to a region), thereby determining the one-segment reception channel. The control unit 207 instructs the one-segment receiving unit 202 through I2C (Inter Integrated Circuit) to tune the determined reception channel. Thereafter, the user enters a standby state (speaker output or character display off state) by a setting completion operation by the user.

  Next, processing of the signal processing unit 203 will be described. FIG. 11 is a flowchart for explaining the signal processing unit 203. When the processing is started, the signal processing unit 203 performs initial setting in response to an instruction from the control unit 207 through the UART (Universal Asynchronous Receiver Transmitter), and performs emergency earthquake warning using the AC signal of the one-segment reception unit 202. Processing of TS signals necessary for detection is started.

  In step S <b> 100, the signal processing unit 203 determines whether an AC header indicating that AC signal information is included in the TS signal information 900 output from the one-segment receiving unit 202 is transmitted. For example, the AC header has 1 byte in the sync byte 901, 1 byte in the indicator 902, and 2 bytes in the length 903. The sync byte 901 represents AC signal information if 0xB0 (hexadecimal B0), and other video and audio information if 0x47. The indicator 902 indicates a start packet if 0x80, an end packet if 0x20, and an intermediate packet if 0x40. The length 903 represents the remaining number of bytes in hexadecimal. One packet is composed of 188 bytes including the header part and the data part, and 0x00 is continuously transmitted until the part less than 188 bytes reaches 188 bytes.

  When the sync byte 901 is 0xB0, the signal processing unit 203 proceeds to the process of step S110 when it detects the header part as an AC header, and repeats the process of step S100 when it is not detected.

  In step S <b> 110, the signal processing unit 203 takes in data (AC signal information 904) following the AC header of the TS signal information 900 and stores it in the signal processing storage unit 204 such as a FIFO memory in the signal processing unit 203.

  In step S120, the signal processing unit 203 determines whether the last byte of the AC signal information 904 has been taken. The signal processing unit 203 proceeds to the process of step S130 if the last byte has been fetched, and returns to the process of step S110 if not fetched. In the present embodiment, the 184th byte of data is the last byte, and the number of bytes represented by 2 bytes of length 903 is valid data as the AC signal information 904.

  In step S <b> 130, the signal processing unit 203 converts the format of the remaining data excluding the header of the TS signal information 900 into a format for sending to the control unit 207. When the 1-bit data of the AC signal information 904 from the one-segment receiver 202 is converted into 1-byte data (hexadecimal 0xFF for binary 0b1 and 0x00 for 0b0), the signal processing unit 203 converts the format of the data from 1 byte to 1 bit (hexadecimal 0xFF is binary 0b1 and 0x00 is 0b0). Data whose format has been converted for each byte is deleted from the signal processing storage unit 204.

  In step S140, the signal processing unit 203 outputs the format-converted data of the AC signal information 904 from the UART 1 to the control unit 207 every 8 bits. When the data output ends, the process returns to the AC header detection process in step S100.

  Although UART1 is used here, another communication method such as 8-bit parallel communication can be used instead.

  FIG. 12 is a flowchart for explaining the control unit 207. The control unit 207 outputs warning contents (emergency warning information) of the emergency earthquake warning according to this flow. When the control unit 207 enters a standby state (speaker output or character display off state) by a setting completion operation by the user, the control unit 207 starts detection processing of a signal transmitted by the signal processing unit 203.

  In step S200, the control unit 207 determines whether the AC signal information 904 is received from the signal processing unit 203 through UART1. If AC signal information 904 is received, the process proceeds to step S210. If not received, the process of step S200 is repeated.

  In step S <b> 210, the control unit 207 takes in the AC signal information 904 received from the UART 1 and stores it in the control storage unit 208 inside the microcomputer 205.

  In step S220, the control unit 207 determines whether or not the last byte of the AC signal information 904 has been captured. If the last byte has been fetched, the process proceeds to step S230, and if not, the process returns to step S210. The final byte is determined by determining the data amount of the packet in advance and determining whether the number of received bytes matches the predetermined data amount of the packet, or the transmission byte at the head of the data transmitted from the signal processing unit 203 This is performed by a method of determining whether or not the number of received bytes matches the number of transmitted bytes in the header by attaching a header that indicates the number.

  In step S230, the control unit 207 determines whether the received AC signal information 904 is an emergency earthquake bulletin. If it is an emergency earthquake warning, the process proceeds to step S240. If not, the control unit 207 proceeds to the determination process in step S200. Return.

A method for determining the earthquake early warning will be described. In the ARIB STD-B31 format data, the value of B ₁ to B ₃ (configuration identification 1001) is 0b001 or 0b110 in binary number in the case of emergency earthquake bulletin among 204 bits data from B ₀ to B _203. If it is not an earthquake early warning, it is specified that it is a value other than that. The control unit 207 refers to these bits and determines whether or not it is an emergency earthquake warning.

  In step S240, the control unit 207 further determines whether or not the area of the emergency (emergency disaster information receiver 100) that is set in advance is included in the area subject to the emergency earthquake warning, and itself (emergency disaster information). If the area of the receiver 100) is included, the process proceeds to step S250. If not included, the process proceeds to step S270.

The determination method of the warning target region of the earthquake early warning, the data format of the ARIB _STD-B31, the data from _{B 56 B 111} (ground motion information 1006), each one region is assigned to one bit, alarm The bit value is defined as “0” when corresponding to the target area, and “1” when not corresponding to the alarm target area. The control unit 207 looks at the value of the bit corresponding to the preset installation area information of itself (emergency disaster information receiver 100), and if “0”, it is included in the alarm target area, and if “1”, it is the alarm target. It is determined that it is not included in the area.

A specific example will be described with reference to FIG. For example, if the area set by the user at the initial setting is Saitama prefecture, “69” that is the assigned bit number 601 corresponding to “Saitama prefecture” is registered in the set area assigned bit number table 404 in advance. Yes. The control unit 207 refers to the set area allocation bit number table 404 and confirms the B ₆₉ data of the earthquake motion information 1006 because the registered data is “69”. Control unit 207 determines that the data of the B ₆₉ is determined to be a warning target area if "0", the data of the B ₆₉ is not included in the warning target region if "1".

  Returning to FIG. 12, in step S <b> 250, the control unit 207 outputs the warning content of the emergency earthquake warning. For example, in the case of character display output, the control unit 207 acquires the fixed character data “Earthquake Early Warning” indicating a warning from the fixed character data table 402 of the control storage unit 208. Further, the control unit 207 refers to the conversion table 401 and acquires the area name character data 602 “Saitama Prefecture” corresponding to the data “69” of the set area allocation bit number table 404 in the data string 615. Further, the control unit 207 acquires the current time 1004 of the AC signal information 904. The control unit 207 acquires the fixed character data for notifying the transmission date and time information indicated by the current time 1004 from the fixed character data table 402. Thereafter, the control unit 207 transmits the fixed character data indicating the date and time and the character data of “Earthquake Early Warning” and “Saitama Prefecture” together with the display output instruction to the image processing unit 210 through the UART (for example, UART2). The image processing unit 210 causes the display unit 101 to display these character data received from the control unit 207. Thereby, for example, the characters “XX month ΔΔ day XX hour XX minute earthquake early warning Saitama prefecture” can be scroll-displayed. Note that year and second information may be appropriately displayed as the date and time information.

  In step S250, one or a plurality of area names different from the area of the own (emergency disaster information receiver 100) in the alarm target area of the earthquake motion information are also displayed on the display unit 101 as reference information or the voice output unit 102. You may make it output to.

  In step S260, the emergency disaster information receiver 100 stores therein the read code of the character data acquired in step S250 as history information. Specifically, in step S250, the control unit 207 uses the read code of the standard character data indicating the date as the date information 702, and the read code of the standard character data indicating the alarm and the area name character data 602 as the alarm video information 703. And stored in the video information history table 405.

  On the other hand, in step S270, the control unit 207 notifies information related to the emergency earthquake bulletin in an area different from the area where the self (emergency disaster information receiver 100) is installed. For example, in the case of character display output, the control unit 207 specifies a bit indicating that it is a warning target area of earthquake motion information from among bits allocated to an area different from the area of itself (emergency disaster information receiver 100). Then, one or a plurality of area name character data 602 corresponding to the specified bit is acquired from the conversion table 401. In addition, the control unit 207 acquires the current time 1004 of the AC signal information 904. The control unit 207 acquires the fixed character data for notifying the transmission date and time information indicated by the current time 1004 and the fixed character data indicating the warning from the fixed character data table 402 of the control storage unit 208. The control unit 207 transmits the acquired area name character data, fixed character data, and image output instruction to the image processing unit 210. Then, the image processing unit 210 can continuously display the fixed character data indicating the date and time and the alarm and the region name character data from the display unit 101.

  In step S280, the emergency disaster information receiver 100 stores therein the read code of the character data or voice data acquired in step S270. Specifically, when the character display output is performed in step S270, the control unit 207 reads the standard character data indicating the date and the region name character data 602 using the read code of the standard character data indicating the date as the date information 702. The code is stored in the video information history table 405 as alarm video information 703.

  When initial setting, if the set area allocation bit number of itself (emergency disaster information receiver 100) is not included in the alarm target area of the earthquake motion information of the emergency earthquake warning, selection of alarm output “ON” or “NO” It is also possible to make it possible. When the user selects the “no” alarm output when the set area code of the user (emergency disaster information receiver 100) does not correspond to the alarm target area of the earthquake motion information, the process of step S270 and step S280 is omitted, or The process of step S270 can be omitted, and the apparatus (emergency disaster information receiver 100) can return to the standby state without outputting the emergency earthquake warning that is not included in the warning target area.

  When the alarm output process and the alarm recording process are finished after a certain period of time, the process enters a standby state (voice output or character display off state), and returns to the determination in step S200.

  Next, another method for outputting the emergency earthquake warning information will be described. The emergency disaster information receiver 100 can output the warning contents of the emergency earthquake warning with sound fixed to the device.

  In the case of fixed sound output, in step S250, the control unit 207 acquires fixed sound data indicating a warning from the fixed sound data table 403 of the control storage unit 208. In addition, the control unit 207 refers to the conversion table 401 and acquires, for example, area name audio data 603 indicating “Saitama Prefecture” corresponding to the data “69” of the set area allocation bit number table 404 in the data string 615. Further, the control unit 207 acquires the current time 1004 of the AC signal information 904. The control unit 207 obtains the standard audio data for notifying the transmission date and time indicated by the current time 1004 from the standard audio data table 403. After that, the control unit 207 transmits the date / time information and the standard voice data indicating the alarm and the area name voice data to the voice processing unit 206 together with a voice output instruction. The audio processing unit 206 outputs these audio data received from the control unit 207 from the audio output unit 102. As a result, when emergency earthquake information is received, disaster prevention alarm information can be reliably output even if the audio signal is transmitted after a delay from the transmitting station or if it takes time to demodulate or decode the audio signal. be able to.

  In step S260, the control unit 207 transmits the readout code of the standard audio data and the area name audio data 603 acquired from the standard audio data table 403 to the signal processing unit 203 together with a registration instruction. Accordingly, the control unit 207 causes the signal processing unit 203 to set the read code of the standard audio data indicating the date as the date information 502 and the read code of the standard audio data indicating the alarm and the area name audio data 603 as the alarm audio information 503. And stored in the voice information history table 301.

  In step S270, the control unit 207 acquires the current time 1004 of the AC signal information 904. The control unit 207 acquires, from the standard audio data table 403 of the control storage unit 208, the standard audio data for notifying the transmission date and time indicated by the current time 1004 and the standard audio data indicating the alarm. The control unit 207 acquires area name voice data 603 of an area that is a warning target area of the earthquake motion information among areas different from the area of itself (emergency disaster information receiver 100). Then, the control unit 207 transmits the standard voice data indicating the date and time and the alarm and the area name voice data 603 to the voice processing unit 206 together with a voice output instruction. The audio processing unit 206 causes the audio output unit 102 to output these audio data received from the control unit 207.

  In step S280, the control unit 207 transmits the readout code of the standard voice data indicating the date and time and the warning and the readout code of the area name voice data 603 to the signal processing unit 203 together with a registration instruction. Accordingly, the control unit 207 causes the signal processing unit 203 to set the read code of the standard audio data indicating the date as the date information 502 and the read code of the standard audio data indicating the alarm and the area name audio data 603 as the alarm audio information 503. And stored in the voice information history table 301.

  Next, another method for outputting the warning contents of the earthquake early warning will be described. The emergency disaster information receiver 100 can output the warning content of the emergency earthquake warning by the received voice.

  For example, when transmitting the AC signal information 803 to the signal processing unit 203, the 1Seg receiving unit 202 transmits the 1Seg audio information 802 in association with the AC signal information 803. If the signal processing unit 203 determines in step S100 that the one-segment audio information 802 associated with the other AC signal information 904 has been received even if the AC header is not detected in the TS signal information 900, Proceed to S110. In step S <b> 110, the signal processing unit 203 stores the one-segment audio information 802 in the signal processing storage unit 204.

  When the control unit 207 determines in step S240 that the installation area information of itself (emergency disaster information receiver 100) is the alarm target area of the earthquake motion information, the process proceeds to step S250. In step S250, the control unit 207 instructs the signal processing unit 203 and the audio processing unit 206 to reproduce the one-segment audio. The signal processing unit 203 decodes the one-segment audio information 802, converts the decoded audio data into a format that can be processed by the audio processing unit 206, and outputs the converted audio data to the audio processing unit 206. The audio processing unit 206 performs digital-analog conversion processing on the audio data from the signal processing unit 203 and outputs the audio data from the audio output unit 102 for a certain time (for example, 3 minutes so that it can be changed by setting).

  In step S260, the control unit 207 instructs the signal processing unit 203 to store the sound information of the emergency earthquake warning as a history. The signal processing unit 203 stores audio data for a predetermined time in the audio information history table 301 as alarm audio information 503 together with date / time information 502. The signal processing unit 203 can store the current time 1004 included in the AC signal information 904 as the date / time information 502.

  In step S270, as in step S250, the control unit 207 causes the audio output unit 102 to output the one-segment audio information 802. In step S280, as in step S260, the control unit 207 stores audio data for a predetermined time in the audio information history table 301 as alarm audio information 503 together with the date / time information 502.

  Next, another method for outputting the warning contents of the earthquake early warning will be described. The emergency disaster information receiver 100 can display video information included in the earthquake early warning.

  For example, when the one-segment receiving unit 202 transmits the AC signal information 803 to the signal processing unit 203, the one-seg receiving unit 202 transmits the video information 801 in association with the AC signal information 803. If the signal processing unit 203 determines in step S100 that the video information 801 associated with the other AC signal information 904 has been received even if the AC header is not detected in the TS signal information 900, the signal processing unit 203 performs step S110. Proceed to In step S <b> 110, the signal processing unit 203 stores the video information 801 in the signal processing storage unit 204.

  When the control unit 207 determines in step S240 that the installation area information of itself (emergency disaster information receiver 100) is the alarm target area of the earthquake motion information, the process proceeds to step S250. In step S250, the control unit 207 instructs the signal processing unit 203 and the image processing unit 210 to reproduce the video information. The signal processing unit 203 decodes the video information 801, converts the decoded video data into a format that can be processed by the image processing unit 210, and outputs it to the image processing unit 210 via the control unit 207. The image processing unit 210 outputs the image data from the signal processing unit 203 from the display unit 101 for a certain time (for example, 3 minutes so that it can be changed by setting).

  In step S260, the control unit 207 stores the video information of the earthquake early warning received from the signal processing unit 203 as a history. The control unit 207 stores video data for a predetermined time in the video information history table 405 as alarm video information 703 together with date / time information 702. Note that the control unit 207 can store the current time 1004 included in the AC signal information 904 as the date / time information 702.

  In step S270, as in step S250, the control unit 207 causes the display unit 101 to display the video information 801. In step S280, as in step S260, the control unit 207 stores video data for a predetermined time in the video information history table 405 as alarm video information 703 together with date and time information 702.

  In addition, the output method of the disaster prevention alarm information in receiving emergency earthquake information can be applied in combination as appropriate. Also, when voice output or text display is performed, if the set area code of itself (emergency disaster information receiver 100) is not included in the alarm target area of the earthquake motion information, the alarm output “No” selection is set at the initial setting. In the case where it is done, the control unit 207 can omit the processes of Step S270 and Step S280, or can omit the process of Step S270.

  As described above, since the emergency disaster information receiver 100 of the present embodiment performs the alarm recording process, it can output the history of past disaster prevention alarm information. For example, the control unit 207 can display the alarm video information 703 in the video information history table 405 or output the alarm audio information 503 in the audio information history table 301 in accordance with an instruction from the input unit 103. At this time, the date and time information stored corresponding to each of the alarm video information 703 and the alarm audio information 503 can be output as appropriate.

  Thus, for example, when the user presses the enter / play button 108, the latest history text information, audio, and video are played back, and when the back button 107 is pressed, the previous (past) history text information, audio, Video is played back. Further, each time the user presses the return button 107, the character information, audio, and video are reproduced by tracing back to the previous (past) history.

  Moreover, when outputting the disaster prevention alarm information in both the character display and the voice output in Step S250 or Step S270, the control unit 207 associates each other with the disaster prevention alarm information as related data in Step S260 and Step S280. Can be stored in the history table. For example, an item number 501 corresponding to the alarm audio information 503 in the audio information history table 301 and an item number 701 corresponding to the alarm video information 703 in the video information history table 405 are associated with each other. Thus, even when the history is output with reference to the video information history table 405, the control unit 207 reads the related alarm audio information by selecting one data, and easily reproduces the alarm audio information. Can be done.

  Further, not only the item number but also date / time information can be associated. For example, when one emergency disaster information is output in both text display and audio output formats, the date information 502 stored in the audio information history table 301 and the date information 702 stored in the video information history table 405 are displayed. Can be linked to the alarm voice information 503 and the alarm video information 703 as related data by the date and time information. Accordingly, for example, the control unit 207 causes the display unit 101 to display the data of the date / time information 702 registered in the video information history table 405, and the user selects arbitrary date / time information using the input unit 103. In accordance with an instruction from the input unit 103, the control unit 207 can cause the output unit to output one or a plurality of data (alarm audio information 503 and / or alarm video information 703) corresponding to one date information 702.

  As described above, according to the present embodiment, the emergency earthquake warning based on the AC signal of the one-segment broadcasting is a dedicated signal, and is more accurate than the chime sound of the radio emergency earthquake warning that is a notification sound for humans. An emergency disaster information receiver with few false detections can be configured. In addition, since the AC signal includes information on the area targeted for the earthquake early warning, it is possible to determine whether the installation location is included in the area targeted for the notification, and to exclude the unrelated rapid reports from the output target. In addition, since the earthquake early warning by one-seg broadcasting uses an AC signal with less delay compared to video and audio of television broadcasting, it is possible to transmit emergency earthquake early warning earlier than video and audio flowing on the television.

  In addition, if you missed the earthquake early warning, it would be difficult to confirm the contents unless the emergency earthquake information was sent again in subsequent broadcasts. It can be replayed and confirmed when you want to hear what kind of alarm has been issued. In addition, date and time announcements may not be made with conventional radio sound, and even when emergency earthquake information is recorded, it may not be known when it was issued. To know when it was announced.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by this embodiment, It can implement with a various form.

  For example, in the present embodiment, the date and time information at which the emergency earthquake information 800 was transmitted was determined according to the information included in the AC signal information, but not limited to this, the date and time acquired from the internal clock in the emergency disaster information receiver 100 The information may be used as data to be registered in the date information 502.

  In the present embodiment, an example is shown in which the audio information history table 301 stores the read code for specifying the audio data to be reproduced in the date information 502 and the alarm audio information 503. However, the present invention is not limited to this. As data registered in the history table 301, audio data may be stored. For example, the date and time information 502 is acquired from the standard audio data indicating the date and time acquired from the standard audio data table 403, and the alarm audio information 503 is acquired from the standard audio data and conversion table 401 indicating the alarm acquired from the standard audio data table 403. The area name audio data 603 can be registered.

  Also, with regard to the video information history table 405, in this embodiment, the date / time information 702 and the alarm video information 703 have shown an example of storing read codes for specifying character data to be displayed. The video data may be stored as data registered in the video information history table 405. For example, the date and time information 702 includes fixed character data indicating the date and time acquired from the fixed character data table 402, and the alarm video information 703 includes the fixed character data acquired from the fixed character data table 402 and the region name character acquired from the conversion table 401. Data 602 can be registered.

  In addition, the signal processing unit 203 and the audio processing unit 206 are configured as processing units different from the control unit 207 of the microcomputer 205, but high-speed processing such as a field-programmable gate array (FPGA) and a digital signal processor (DSP) is performed. Any possible device can be configured as one processing unit. In this case, the signal processing storage unit 204 and the control storage unit 208 may be configured as one storage unit.

It is also possible to apply to various devices. As described above, by storing the processes described in the present embodiment in a desired storage medium and causing the program to be executed by another computer or the like, it is possible to obtain the same operational effects as when the apparatus of the present embodiment is used. The computer is not limited to the computer built in the apparatus described in the present embodiment, but can read a program stored in a storage medium and can perform a control operation according to the read program. Includes any computer equipped with a computing device.
