Description

  The present invention relates to a breaking news receiving apparatus that receives breaking news such as emergency earthquake breaking news, natural disaster breaking news, and news breaking news.

  Since 2007, the Japan Meteorological Agency has begun operating emergency earthquake warnings. Earthquake early warning detects the initial tremor of an earthquake and immediately estimates the epicenter and magnitude (magnitude) of the earthquake, and based on this, predicts the arrival time and seismic intensity of the main motion in each location, and informs it as quickly as possible. Therefore, it is intended to prevent or reduce earthquake damage as much as possible.

  As a transmission path used for transmitting the earthquake early warning data obtained by converting the earthquake early warning data, there are considered a path using digital terrestrial broadcasting and a path using mail for mobile terminals.

  Transmission means for transmitting emergency earthquake bulletin data in a route using digital terrestrial broadcasting: First, transmission means using character supermarkets using asynchronous PES; second, transmission means using event messages using data carousels Thirdly, transmission means for encoding and transmitting regional information and epicenter information to the one-segment broadcast Auxiliary Channel (hereinafter referred to as AC) has been studied (for example, see Patent Document 1).

  Since the data transmitted here is operated based on the conventional digital terrestrial broadcasting standard, the character supermarket is operated in accordance with ARIB standard TR-B14, Part 3, and the character encoding system is changed to ARIB STD-B24, Part 1. It is transmitted using the specified 8-unit character code. The event message is operated in accordance with ARIB standard TR-B14, third edition, like the character supermarket, and is transmitted using the character code defined in STD-B24, second edition as the character encoding system. In the digital terrestrial broadcasting AC, a new standardized code is encoded and transmitted.

  Also, transmission means using broadcast mail are being considered for routes using mail for mobile terminals. The broadcast mail is transmitted as emergency earthquake warning data encoded in accordance with ISO-2022-jp.

JP 2007-243936 A

  However, in the conventional system, a plurality of emergency earthquake bulletins are transmitted in parallel as emergency earthquake bulletin data converted by a digital terrestrial broadcaster or mobile phone operator based on the encoding method corresponding to each transmission means. The It is known that each earthquake early warning data is received with a slight time lag due to a difference in transmission means. In this case, if the receiving device has a function of receiving a plurality of earthquake early warning data transmitted in parallel by a plurality of transmission means, naturally, the contents of the earthquake early warning will be notified multiple times. .

  Thus, notifying the same earthquake early warning based on the same earthquake more than once has the problem that the viewer of the receiving device may feel the notification complicated or annoyed. Was.

  Such a problem is not limited to emergency earthquake bulletins, but also occurs when things like natural disaster bulletins and news bulletins are sent in parallel by a plurality of transmission means.

  An object of the present invention is to solve the above-mentioned problem, and to provide a breaking news receiving apparatus that improves the convenience of viewers without unnecessarily repeatedly notifying the contents of breaking news related to what has already been announced. It is said.

  In order to solve the above-described conventional problems, a receiving apparatus according to the present invention includes: a receiving unit that receives a plurality of breaking data in which breaking information is converted into data based on a plurality of encoding methods; and A format conversion unit for converting into new breaking data based on the encoding method, a storage unit for sequentially storing the new breaking data, a control unit for comparing the newly stored breaking data with each other, and the control Based on the result of the comparison in the unit, a bulletin receiving device having a notification unit for performing notification processing of the content of the bulletin from the new bulletin data.

  According to the breaking news receiving apparatus of the present invention, it is possible to compare the breaking data by converting the coding method of the breaking data to a specific encoding method, so the contents of the breaking news are related to the breaking news received so far. Therefore, it is possible to improve the convenience for the viewer.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 5.
<Description of the device>
FIG. 1 is a block diagram of an earthquake early warning receiving apparatus 1 having a digital terrestrial broadcast receiving function and a mobile terminal mail function, which is an example of an embodiment of the breaking news receiving apparatus of the present invention. The earthquake early warning receiving device 1 can receive not only the earthquake early warning but also digital terrestrial broadcasting and e-mail for mobile terminals. Here, it is assumed that the viewer usually uses the earthquake early warning receiver 1 as an application for viewing digital terrestrial broadcasting.

Hereinafter, the embodiment will be described in detail with reference to FIG.
<Viewing digital terrestrial broadcasting>
When the terrestrial digital broadcast is received by the terrestrial digital broadcast receiving antenna 2, it is selected by the tuner 3 which is a part of the receiving unit. The digital broadcast data selected and received by the tuner 3 is demodulated into a transport stream by the demodulator 4.

  The demodulated transport stream is extracted by the transport decoding unit 5 by filtering necessary data such as video and audio.

The extracted video data and audio data are decoded by the AV decoding unit 6 into a format that can be output to various output devices. The video data is displayed on the display unit 8 by the display control in the display control unit 7. Audio data is output from the speaker 9.
<Receiving function for e-mail for mobile devices>
Next, the portable terminal function provided in the earthquake early warning receiver 1 will be described. Here, of the portable terminal functions, the explanation will focus on the function of receiving the earthquake early warning mail for explanation.

  First, the mobile terminal antenna 10 communicates with a mobile phone base station (not shown) to receive mail. Next, the RF unit 11 as a part of the receiving unit demodulates the mail received by the mobile terminal antenna 10. The mail data demodulated by the baseband unit 12 is decoded into character information.

Since the earthquake early warning receiving device 1 is a digital terrestrial broadcast receiving device, the body of the decoded emergency earthquake early warning mail is adjusted to an easy-to-read format by the earthquake early warning display processing unit 13, and the display control unit 7 converts it to an image of digital terrestrial broadcasting. Superimpose and display on the display unit 8.
<Reception of earthquake early warning data>
Next, an operation when the earthquake early warning receiving device 1 receives the earthquake early warning data generated based on different encoding methods will be described. Here, it is assumed that the scenes are different in each explanation, and the operation when only one type of emergency earthquake early warning data is received is explained.
<Contents of earthquake early warning data>
FIG. 2 shows an example of a packet configuration of the earthquake early warning data. The earthquake early warning data is encoded with the earthquake early warning descriptor indicating that the data to be transmitted is the emergency earthquake early warning, start_end_flag indicating the data delimiter, regional information, epicenter information, predicted seismic intensity, etc. It is included.

  The contents of the emergency earthquake bulletin include a string consisting of “emergency earthquake bulletin” indicating the content of the bulletin, information on the prefectures necessary to identify the epicenter and region, and information on islands, peninsulas, and bays that are larger than a certain standard. A character string indicating information such as direction and direction indicating an epicenter with respect to prefectures, islands, peninsulas and bays, a character string indicating a seismic intensity, and a character string indicating strength information.

  Each character string is an 8-unit character code described in ARIB STD-B24 Volume 1 when transmitted as a character superscript, and an EUC which is a character code defined in Volume 2 of STD-B24 when transmitted as an event message. -When transmitting in JP or AC, the code code for the earthquake early warning descriptor shown in Table 1 and the code specified in ISO-2022-jp used in mail are as shown in Table 1 Corresponding, converted and transmitted.

  Tables 1 to 4 show the correspondence table between the contents of emergency earthquake warnings and codes.

  Table 1 is an encoding correspondence table showing how a character string composed of “Earthquake Early Warning” is encoded in each encoding method.

  Table 2 shows how character strings indicating information on prefectures, islands, peninsulas, and bays that are larger than a certain standard are specified in each encoding method. It is the encoding corresponding | compatible table which showed.

  Table 3 is an encoding correspondence table showing how character strings indicating information such as direction and direction indicating the epicenter are encoded in each encoding method based on prefectures, islands, peninsulas and bays. It is. In this embodiment, as the means for indicating the epicenter, the direction and direction are used with reference to prefectures, islands, peninsulas and bays as described above. However, specific numerical values of latitude and longitude may be used.

  Table 4 is an encoding correspondence table showing how a number indicating seismic intensity and a character string indicating strength information are encoded in each encoding method.

<Reception of earthquake early warning data by AC of one segment broadcasting>
First, the operation when the earthquake early warning data is received using the one-segment broadcasting AC will be described. Here, the emergency earthquake bulletin data encoding method uses the emergency information descriptor in a format that conforms to the provisions of ARIB TR-B14 Part 4, and the regional information that is specified in ARIB TR-B14 Part 7. It shall be encoded based on a conforming format.

  The AC detection unit 14 extracts data transmitted by the one-segment broadcasting AC from the demodulation unit 4 and monitors whether an emergency earthquake bulletin descriptor is transmitted.

  For example, if “0a” is detected in a loop representing area information following start_end_flag, it is recognized as “Hokkaido” as shown in Table 2.

  Subsequently, if, for example, “0a c0 d0” is detected in the loop representing the epicenter information, it is recognized as “off the eastern Hokkaido” as shown in Tables 2 and 3. Similarly, if, for example, “e5 ee” is detected in the loop representing the predicted seismic intensity, it is recognized that the seismic intensity is less than 5 as shown in Table 4.

  In the format conversion unit 15a, data such as regional information, epicenter information, and predicted seismic intensity among emergency earthquake early warning data detected by AC is converted into ISO-2022-jp codes by referring to the character string database 16 from Table 1 to Table 4. And stored in the storage unit 17 as shown in Table 5.

  Here, the character string database 16 has a data table corresponding to the encoding correspondence table shown in Tables 1 to 4, and includes a character string included in the earthquake early warning and data included in the earthquake early warning data. The correspondence is memorized. The provision of such a character string database 16 is useful for converting data included in the earthquake early warning to a state that can be compared later.

  As shown in Table 2, the regional code “0a” representing “Hokkaido” is represented in code “4b 4c 33 24 46 3b”, and the epicenter code “0a c0 d0” representing “Hokkaido east off” is represented in Table 2 and Table 3. As shown in Table 4, the code “4b 4c 33 24 46 3b 45 6c 4a 7d 32 3d” and the predicted seismic intensity code “e5 ee” representing “seismic intensity 5 weak” are converted to the code “23 35 3c 65” as shown in Table 4. Then, the transmission means and the number of bytes of data to be stored are added and stored in the storage unit 17.

  Since the amount of data assigned to AC is limited, for example, a prefecture name may be assigned to a specific bit as regional information, or specific numerical values such as latitude and longitude may be used as epicenter information.

  As data representing the transmission means, for example, the mail for mobile terminals is “0”, the one-segment AC is “1”, the character superimpose is “2”, and the event message is “3”. Therefore, “1” is added when receiving earthquake early warning data by AC of one-segment broadcasting.

  At the same time, since the current time can be obtained from the TOT (Time Offset Table) transmitted by the terrestrial digital broadcast, the transport decoding unit 5 acquires the time when the emergency earthquake warning is detected and stores it in the storage unit 17.

The earthquake early warning display processing unit 13 acquires the emergency earthquake early warning data received from the storage unit 17 via AC,
A message is created in a predetermined format, and the message is superimposed on the video signal by the display control unit 7.

  Notification of emergency earthquake warnings to viewers is performed by the notification section performing notification processing. Announcement refers to audio, video, and other things that can be perceived by the viewer and communicated to the viewer. The notification process refers to a process that speaks and displays the contents of the earthquake early warning.

In the present embodiment, the notification process of the notification unit is performed by the display unit 8 displaying character information. Specifically, the display unit 8 notifies the viewer by displaying the superimposed message. A display example is shown in FIG. In the present embodiment, the notification process of the notification unit is performed by the speaker 9 by uttering text information.
<Reception of earthquake early warning data by supermarket>
Next, the operation of the earthquake early warning receiving device 1 when the earthquake early warning is transmitted by the character supermarket will be described.

  If the character super is transmitted by the independent PES, the character super data is filtered by the transport decoding unit 5 and sent to the character super detection unit 18.

  The character super detection unit 18 analyzes the character super data in accordance with the 8-unit character code system described in the ARIB STD-B24 volume 1. Although the character super data includes a display control code for displaying the character super on the display unit 8, the character super detection unit 18 refers to the character string database 16 to search for the character code.

  As the text of the text super, for example, “Emergency Earthquake Bulletin”, “The epicenter is off the east of Hokkaido”, “Estimated seismic intensity of less than 5”, “Please pay attention to strong earthquakes in the Hokkaido area”. As the character string characterizing the earthquake, “Emergency Earthquake Early Warning”, “Hokkaido East Off”, “Slightly Less than 5”, and “Hokkaido” are detected, and at the same time, the current time information reproduced from the TOT is acquired from the transport decoding unit 5.

  The detected character string is converted into an ISO-2022-jp code by the format conversion unit 15b with reference to the character string database 16, and data representing the transmission means ("2" because it is a character super), the number of bytes of data, The acquired current time information is added and stored in the storage unit 17.

The character super data is sent from the transport decoding unit 5 to the AV decoding unit 6 and superimposed on the video as a character super. The display control unit 7 performs display control and displays the data on the display unit 8 for the viewer. Notice.
<Reception of earthquake early warning data by event message>
Next, the operation of the earthquake early warning receiving device 1 when an earthquake early warning is transmitted by an event message will be described.

  When an event message exists in the data carousel, the event message data is filtered by the transport decoding unit 5 and sent to the event message detection unit 19.

  The event message detection unit 19 analyzes the event message data in accordance with the character encoding system described in the ARIB STD-B24 Vol. 2, but will be described with reference to the EUC-JP code in the following description.

  The event message detection unit 19 searches the character code with reference to the character string database 16. For example, if the event message text is “Emergency Earthquake Bulletin”, “The epicenter is off the east of Hokkaido,” “Earthquake seismic intensity is less than 5”, or “Please be careful of strong earthquakes in the Hokkaido region”, the event message detection unit 19 "Emergency earthquake bulletin", "Hokkaido east offshore", "Slightly less than 5", and "Hokkaido" are detected as the character strings characterizing, and the current time information reproduced from the TOT is acquired from the transport decoding unit 5.

  The detected character string is converted into an ISO-2022-jp code by the format conversion unit 15c with reference to the character string database 16, and data indicating the transmission means (“3” because it is an event message), the number of bytes of data, The acquired current time information is added and stored in the storage unit 17.

The event message data is sent from the transport decoding unit 5 to the AV decoding unit 6 and superimposed on the video as multimedia data. The display control unit 7 controls the display and displays the data on the display unit 8 for viewing. To announce.
<Reception of earthquake early warning data by e-mail for mobile devices>
Next, the operation of the earthquake early warning receiving device 1 when an earthquake early warning is transmitted by e-mail for mobile terminals will be described.

  When an earthquake early warning mail is received from a mobile phone base station (not shown) via the mobile terminal antenna 10, the RF unit 11 detects a signal indicating the emergency earthquake early warning, demodulates it, and demodulates the mail text. Extracted and sent to the baseband unit 12.

  The baseband unit 12 analyzes the mail text data according to ISO-2022-jp. The baseband unit 12 searches the character code with reference to the character string database 16.

  As described above, in the present embodiment, when the earthquake early warning data based on the same encoding method as ISO-2022-jp corresponding to the specific encoding method in the present invention is received, the processing time is shortened. For this reason, it is not necessary to convert the encoding method.

  The character string that has not been converted, the data representing the transmission means (“0” because it is a mail for portable terminals), the number of bytes of data and the acquired current time information are added and stored in the storage unit 17.

  Here, for example, if you send text information such as "Earthquake Early Warning", "The epicenter is off the eastern Hokkaido", "Earthquake seismic intensity of less than 5", or "Please pay attention to strong earthquakes in the Hokkaido area", character string data will be detected. The operation of storing data in the storage unit 17 is the same as that in the case of the character superimposition. The data of the text of the earthquake early warning mail is adjusted to an easy-to-read format by the earthquake early warning display processing unit 13, superimposed on the video by the display control unit 7, and displayed on the display unit 8 to notify the viewer.

Note that the notification means may be based on voice processing in addition to display processing.
<Reception of earthquake early warning data by multiple transmission means>
Next, processing of a plurality of earthquake early warnings continuously received by a plurality of transmission means will be described with reference to FIG. In FIG. 4, steps S0 to S7 correspond to the following transition states.

  First, it is assumed that the earthquake early warning receiving apparatus 1 is viewing digital terrestrial broadcasting and is in a standby state as a function of receiving an earthquake early warning. (Step S0). It is determined whether emergency earthquake warning data has been received from any of the transmission means described above (step S1). When the earthquake early warning data is received in step S1, it is converted into an encoding method conforming to a specific encoding method ISO-2022-jp (step S2). If the earthquake early warning data is not received in step S1, the process returns to the standby state in step S0.

  Next, the converted earthquake early warning data is stored in the storage unit 17 (step S3). It is determined whether or not the earthquake early warning data already received in the storage unit 17 is present (step S4). When the earthquake early warning data exists in the storage unit 17 in step S4, the emergency earthquake early warning data received by the control unit 20 is compared with the emergency earthquake early warning data existing in the storage unit 17 (step S5).

  Here, in each format conversion unit, the earthquake early warning data previously generated based on a different encoding method is unified into a specific encoding method conforming to ISO-2022-jp. As a result of the conversion, an effect peculiar to the present invention that the control unit 20 enables comparison is exhibited.

  Based on the comparison result in step S5, it is determined whether the data is equal to the emergency earthquake warning data stored in the storage unit 17 (step S6). If it is not equal to the earthquake early warning data stored in the storage unit 17 in step S6, the content of the received emergency earthquake early warning is displayed on the display unit 8 to notify the viewer (step 7). In addition, when there is no earthquake early warning in the storage unit 17 in step S4, the notification process in step S7 is performed in the same manner.

  After the notification process in step S7, the process proceeds to the standby state in step S0 in a state where one piece of emergency earthquake warning data is additionally stored in the storage unit 17. Moreover, if it is equal to the earthquake early warning data memorize | stored in the memory | storage part 17 in step S6, it will transfer to the standby state of step S0, without notifying the earthquake early warning of the same content.

  By such a process, there is an advantage that the viewer of the earthquake early warning receiving apparatus 1 is not notified of the same earthquake early warning unnecessarily, and there is no need to make unnecessary effort.

  Further, the control unit 20 may compare the received earthquake early warning data with all the data stored in the storage unit 17 or may compare only the data received recently. When comparing with only recently received data, there is an advantage that the time required for data comparison is small.

  Table 5 shows an example of data stored in the storage unit 17 when the earthquake early warning is received by each transmission means as described above.

  Data No. 1 to No. 4 is a number assigned to the earthquake early warning data received at 1-second intervals. 2 to No. 3, in step S6 of FIG. 2 is data No. 1 and data no. 3 is data No. 2 or No. 1 and data no. 4 is data No. 3 to No. 1 and the contents of the earthquake early warning data match. The notification to the viewer is data No. 1 is performed only when the first earthquake early warning data is received.

  Here, when it is determined that the contents match by comparing the earthquake early warning data, any one of the data having the matched contents may be deleted from the contents of the storage unit 17. This saves the capacity of the storage unit 17 while any one of the data remains, and there is an advantage that a situation in which no comparison data exists on the storage unit 17 does not occur.

Moreover, the comparison of the contents of the emergency earthquake warning data performed by the control unit 20 not only confirms the identity, but also can be used for various purposes. The contents of the notification process based on the comparison result are also used by the viewer. Various things can be considered depending on the situation. For example, when the area is the same but the seismic intensity is different compared to the emergency earthquake bulletin announced immediately before, an emphasis display such as “It is different from the previous earthquake” is added to the display unit 8. By doing so, the viewer can be further alerted.
<Timed control>
Moreover, even if it is determined that the notification process is not performed as a result of the comparison, if the reception date / time is different by a predetermined time, for example, 1 minute or more, it is determined as another earthquake early warning. Timed control may be performed such as displaying.

  The operation of the earthquake early warning receiver 1 will be described with reference to Table 5 again for the timed control. In Table 5, data No. 5 is data No. 4 was received 30 minutes later. Therefore, there is a difference in reception time of 1 minute or more. Therefore, when performing timed control, even if the contents of the emergency earthquake bulletin data match, the emergency earthquake bulletin receiver 1 performs notification processing.

  In general, even if the same earthquake early warning data is transmitted as emergency earthquake early warning data in parallel through a plurality of different transmission paths and transmission means, the time lag measured by the receiving device is not so long. is assumed. Therefore, by performing such timed control, there is a slight risk that the same earthquake bulletin will be announced twice, but there is a risk that the emergency earthquake bulletin reported by an earthquake that is accidentally the same and actually different will not be announced. Can be avoided.

  Here, the time comparison is not limited to using data based on TOT. In short, any configuration may be used as long as it can confirm the elapsed time from the reception of the latest earthquake early warning data. For example, by using a circuit such as a timer separately, whether the timer is activated from the time of receiving the latest earthquake early warning data, and when the earthquake early warning data is subsequently received, whether the timer is within the operating time range It is also possible to perform control to ensure that the processing is performed within a certain period of time.

  If the difference between the time when the earthquake early warning data was received and the time when the most recent earthquake early warning data was received is equal to or greater than the predetermined interval, the emergency earthquake early warning data will not be converted and / or compared immediately. It is good also as a structure which notifies an earthquake early warning.

  FIG. 5 is a flowchart showing the operation of the earthquake early warning receiving apparatus 1 in such a configuration. Differences from FIG. 4 are as follows.

  After determining that the earthquake early warning data has been received in step S1 for determining whether the earthquake early warning data has been received by any of the transmission means described above, the time immediately before receiving the emergency new data and immediately before The difference from the time when the emergency new data is received is calculated, and it is determined whether or not it is a predetermined time or more (step S1a). If it is determined in step S1a that there is an interval equal to or longer than a predetermined time, the contents of the emergency earthquake bulletin received immediately are displayed on the display unit 8 to notify the viewer (step S1b).

  By doing so, it is possible to notify the earthquake early warning data that can be considered to contain the content of another earthquake early warning that has already been notified, before performing processing such as comparison and conversion. There is an advantage that it is possible to ensure the promptness of notification as needed while maintaining the effect of the present invention on the earthquake early warning.

  If there is no difference equal to or greater than the predetermined interval in the determination in step S1a, the emergency earthquake warning data is converted into an encoding method conforming to ISO-2022-jp which is a specific encoding method (step S2). After step S2, the same processing as in FIG. 4 is performed. However, even if notification is necessary because the contents of the earthquake early warning data are different depending on the determination in step S6a, if the notification has already been made in step S1b, the notification with the same contents is made in a short time. In order to avoid performing the process, the process does not proceed to step S7 but returns to the standby state.

  Here, the detection of the reception time of the emergency earthquake bulletin received immediately before may be made by referring to the TOT additionally recorded in the storage unit 17 or by using a configuration such as a timer that starts a countdown every time reception is performed. Good.

  Data No. 6 is data No. Because it was received after 30 seconds of 5, emergency earthquake bulletin is not immediately notified by timed control. However, since it is determined that the earthquake early warning data is different from the earthquake early warning data 30 seconds before by comparing the earthquake early warning data, it is necessary to make a notification. Here, for example, when notification is made even after the contents of the earthquake early warning data have been found to be different by comparison, the viewer's attention is warned, such as "It is different from the emergency earthquake warning 30 seconds ago." It is conceivable that a message prompting the user is displayed on the display unit 8.

  In addition, data No. 6 is data No. Since the capacity of the data stored in the storage unit 17 is different from that in FIG. 5, such information may be used as a comparative material to make a notification without comparing other elements.

  As a receiving function of digital terrestrial broadcasting, a fixed receiving device for home use that receives 12-segment broadcasting can be considered. As an example of transmission of earthquake early warning, we have explained AC, text super, event message, and e-mail for mobile terminals for one-segment broadcasting. However, it is not necessary to have all these means as means for transmitting earthquake early warning. Needless to say.

  Further, although ISO-2022-jp is adopted as an example for a specific encoding method, other codes may be used. As mentioned earlier, one of the encoding methods used to generate receivable earthquake early warning data has the advantage that the conversion process of at least the earthquake early warning data generated based on the encoding method can be omitted. In fact, if it is the most commonly received encoding method used to generate receivable emergency earthquake warning data, there is an advantage that conversion processing of a lot of earthquake early warning data can be omitted. More desirable from.

  Further, the predetermined time, which is a threshold value used for timed control, is not limited to 1 minute as in the present embodiment, and may be set appropriately by the viewer.

  In this embodiment, an example of an earthquake early warning receiving device that receives and notifies an emergency earthquake bulletin has been shown. However, the present invention receives not only an emergency earthquake bulletin but also a natural disaster bulletin, a news bulletin, etc. It can also be applied to a device.

  According to the receiving apparatus of the present invention, it is possible to improve the usability of the viewer, so that it is useful as a breaking news receiving apparatus.
