The tuner 312 is connected to the antenna 311, and selects a channel of a target broadcast station such as the Japan Broadcasting Corporation (NHK) according to the user's selection from among a plurality of television broadcast waves received by the antenna 311. Channel selection is performed, and image data, audio data, and the like indicating broadcast contents based on the television broadcast wave of the selected broadcast station are transferred to the large-capacity storage unit 314. The tuner 312 corresponds to a first broadcast receiving unit.

  The communication unit 313 is connected to a network 318, and the network 318 performs data communication by wireless communication with a mobile terminal device such as the mobile phone device 400 via the base station 319. At this time, image data and audio data indicating the broadcast contents are transmitted and received. The network 318 is not particularly limited, and includes, for example, the Internet, a wireless LAN, and a telephone line. By these networks 318, an electronic program guide (EPG) for making a recording reservation. Various information can be received. The communication unit 313 corresponds to a first communication unit.

  The large-capacity storage unit 314 includes an encoder and a decoder, and the image data and audio data transferred from the tuner 312 are compressed by the encoder into a predetermined file format, such as MPEG (Moving Picture Experts Group phase) format. The compressed data is output to a connected hard disk drive (hereinafter referred to as HDD). The HDD has a built-in hard disk (hereinafter referred to as HD) and records the compressed data on the HD in file units. The compressed data recorded on the HD can be decoded and decompressed to the original image data and audio data by a decoder. The large capacity storage unit 314 corresponds to a storage unit.

  The operation unit 315 is an operation unit for operating the operation of the hard disk recorder 300, and includes keys such as function keys for setting or selecting various functions. Examples of the function keys include a recording key for starting recording processing, a reproduction key for starting reproduction processing of recorded recording data, and a stop key for stopping recording processing or reproduction processing. When the user performs a key operation, the operation unit 315 inputs a key operation detection signal corresponding to the key operation to the CPU 317. The CPU 317 identifies the input key operation detection signal, and executes a predetermined process according to the identification result, such as a recording process or a reproduction process.

The storage unit 316 includes, for example, a RAM (Random Access Memory) and a ROM (Read Only).
The CPU 317 stores a program for controlling the operation of each part constituting the hard disk recorder 300, a control command from the CPU 317, and the like. The CPU 317 is mainly composed of a microcomputer, and controls the operation of each part constituting the hard disk recorder 300, executes a program read from the storage unit 316, and the like. The storage unit 316 and the CPU 317 correspond to a first control unit.

First, the operation of the hard disk recorder 300 during normal operation will be described.
In a normal operation, when the user gives a recording process start instruction by operating the key of the operation unit 315, the CPU 317 causes the antenna 311 to receive a television broadcast wave from the broadcast station 200. The tuner 312 selects a channel of a target broadcasting station such as the Japan Broadcasting Corporation (NHK), for example, according to the user's selection from a plurality of television broadcast waves received by the antenna 311. Then, image data, audio data, and the like indicating the broadcast content based on the television broadcast wave of the broadcast station are transferred to the large-capacity storage unit 314. The large-capacity storage unit 314 encodes and compresses image data, audio data, and the like transferred from the tuner 312 into compressed data in a predetermined file format, for example, MPEG format, by an encoder, and the compressed data is transferred to the connected HDD. Output. The HDD records the compressed data on the HD in file units. The above-described recording process is continued until a recording process stop instruction is issued by the user through a key operation on the operation unit 315, or until a predetermined recording time and recording end time have elapsed by the reserved recording function.

  In the case of performing scheduled recording using the EPG, if the user gives an instruction to perform scheduled recording by operating the key of the operation unit 315, the CPU 317 performs a television receiver or the like based on the EPG acquired and stored in advance. The reservation screen is displayed on a display unit such as a playback device (not shown). The user can make a recording reservation for the target program based on the reservation screen. In addition, the recording instruction and the reservation recording instruction can be performed by e-mail or the like via a communication unit 313 from a mobile terminal device such as the mobile phone device 400. Then, the hard disk recorder 300 performs a recording process based on an instruction included in the received e-mail or the like.

  When the CPU 317 determines that a notification signal instructing notification processing for transmitting recording data in which image data, audio data, and the like are recorded from a portable terminal device such as the cellular phone device 400 is received, the communication unit 313. In addition, each compressed data recorded on the HD is read out, and the compressed data is transmitted to the portable terminal device by electronic mail via the network. In the above configuration, the compressed data is transmitted. However, the present invention is not particularly limited to this. For example, the compressed data recorded on the HD in the large-capacity storage unit 314 is converted into the original image data and audio data. For example, the data may be decoded and decompressed and transmitted to the mobile terminal device via a network.

  On the other hand, when the CPU 317 determines that the notification signal has not been received, the notification process is stopped.

  When the user gives an instruction to start playback processing of recorded data by operating the key of the operation unit 315, the CPU 317 uses the decoder to convert each compressed data recorded in the HD in the large-capacity storage unit 314 and the original image data. Audio data or the like is decoded and expanded, and these data are transmitted to a playback device (not shown) such as a television receiver connected to the hard disk recorder 300.

  Next, the operation of the hard disk recorder 300 when receiving an emergency warning broadcast signal will be described. The tuner 312 of the hard disk recorder 300 is always supplied with power and is in an operating state. Then, the broadcast wave received by the antenna 311 is monitored to determine whether the antenna 311 has received a broadcast wave including an emergency warning broadcast signal.

  The emergency warning broadcast signal used in the event of a disaster is a first type start signal that conveys a warning declaration such as the Tokai earthquake, requests from the governor and mayors, and a second type start that broadcasts that a tsunami warning has been issued There are three types of signals: a signal and an end signal indicating the end of the start signal. During emergency alert broadcasting, the start signal and end signal are sent as a pair, and an emergency alert broadcast is inserted between the start signal and end signal Is done. Therefore, as a method for determining whether or not a broadcast wave including an emergency warning broadcast signal has been received, for example, a method for detecting a start signal such as a first type start signal or a second type start signal from the broadcast station 200, or Examples include a method of detecting a difference in modulation method between a normal broadcast wave and a broadcast wave including an emergency warning broadcast signal.

  When tuner 312 determines that antenna 311 has received a broadcast wave including an emergency alert broadcast signal from broadcast station 200, tuner 312 transmits an emergency alert broadcast start signal notifying the start of emergency alert broadcast to CPU 317. When the CPU 317 receives the emergency warning broadcast start signal, the CPU 317 transmits a recording start instruction signal instructing the tuner 312 and the large capacity storage unit 314 to start the recording process. The tuner 312 that has received the recording start instruction signal transfers image data, audio data, and the like indicating the broadcast content of the emergency alert broadcast to the large-capacity storage unit 314 based on the emergency alert broadcast signal. The large-capacity storage unit 314 The transferred image data, audio data, and the like are encoded and compressed by an encoder into compressed data of a predetermined file format, for example, MPEG format, and the compressed data is output to the connected HDD. The HDD records the compressed data on the HD in file units. At this time, if the hard disk recorder 300 includes a plurality of tuners 312 and there is a tuner 312 that is not used during normal operation, an image indicating the broadcast content of the emergency alert broadcast using one of the tuners 312. Data and audio data may be transferred.

  When the antenna 311 receives an end signal indicating the end of the emergency alert broadcast included in the emergency alert broadcast signal, the tuner 312 transmits an emergency alert broadcast end signal notifying the end of the emergency alert broadcast to the CPU 317. When the CPU 317 receives the emergency warning broadcast end signal, the CPU 317 transmits a recording end signal instructing the end of recording to the tuner 312 and the large capacity storage unit 314. When receiving the recording end signal, the tuner 312 and the mass storage unit 314 end the recording process.

  Further, the CPU 317 is a notification-unnecessary signal indicating that notification of notification information such as video data indicating the broadcast content of emergency alert broadcast and recorded data recorded from the mobile terminal device such as the mobile phone device 400 is unnecessary. Is received. If it is determined that the notification unnecessary signal has not been received, the communication unit 313 reads each compressed data recorded in the HD, and transmits the compressed data to the portable terminal device by e-mail via the network. . At this time, the subject of the e-mail is set to “emergency alert broadcast occurrence” or the like so that the user can easily determine that the information is related to the emergency alert broadcast. In the above configuration, the compressed data is transmitted. However, the present invention is not particularly limited to this. For example, the compressed data recorded on the HD in the large-capacity storage unit 314 is converted into the original image data and audio data. For example, the data may be decoded and decompressed and transmitted to the mobile terminal device via a network. On the other hand, when it is determined that the notification unnecessary signal has been received, the notification processing is stopped. Further, even when the notification process is in progress, the notification process is stopped.

  In the above embodiment, e-mail is used as a method for transferring recorded data by the communication unit 313. However, the present invention is not particularly limited thereto, and for example, streaming communication may be used. Also in the case of using e-mail, in the above embodiment, the compressed data is transmitted in order to reduce the capacity of the e-mail. However, the present invention is not particularly limited to this. In addition, when using streaming communication, the configuration may be such that notification processing of recorded data in the middle of recording can be performed before the recording processing is completed, so that an emergency alert can be given to the user carrying the mobile terminal device more quickly. It is possible to inform about the occurrence of broadcast and its contents.

Further, in the above embodiment, in order to make it easier for the user to determine that the information is related to the emergency alert broadcast, the subject of the e-mail is “emergency alert broadcast occurrence” or the like, but is not limited to this. A predetermined fixed sentence or file indicating information related to emergency alert broadcasting may be attached to the text. If streaming communication is used, a method of putting audio indicating information related to emergency alert broadcasting at the beginning of streaming, or SMIL (Synchronized Multimedia transmitted before starting streaming)
For example, there is a method to describe in a file such as (Integration Language) that the information is related to emergency alert broadcasting.

  The emergency alert broadcast recording process is preferably performed regardless of whether a notification-unnecessary signal is received. As a result, even if the user who has the portable terminal device cannot receive the emergency alert broadcast due to movement by a vehicle such as a subway, the emergency alert can be performed by performing the notification processing of the recorded data later. You can watch the broadcast.

  As described above, when the hard disk recorder 300 according to the first embodiment of the present invention receives a broadcast wave including an emergency warning broadcast signal from the broadcast station 200, the hard disk recorder 300 notifies the mobile terminal device that the emergency warning broadcast signal has been received. When the tuner 312 serving as the first broadcast receiving means receives the emergency alert broadcast signal from the broadcast station, the storage unit 316 and the CPU 317 serving as the first control means When it is determined whether or not a notification-unnecessary signal indicating that transmission of notification information such as recorded data including image data and audio data indicating broadcast content is unnecessary is received from the mobile terminal device, and a notification-unnecessary signal is received If it is determined, the transmission of the notification information to the mobile terminal device is stopped. As a result, the hard disk recorder 300 can be prevented from transmitting notification information to the mobile terminal device when it is not necessary, and the use of the communication line can be reduced. The influence on the communication line can be reduced.

  In addition, the hard disk recorder 300 is a large-capacity storage unit 314 that is a storage unit that stores at least one of image data and audio data indicating the broadcast content of the emergency alert broadcast based on the received emergency alert broadcast signal. Is provided. Accordingly, at least image data or audio data indicating the content of the emergency alert broadcast stored in the large-capacity storage unit 314 for a user who has a portable terminal device and is unable to receive the emergency alert broadcast. Either one of the data can be transmitted, and the user can watch the emergency alert broadcast even after the fact. In addition, the user can know in detail not only the occurrence of the emergency warning broadcast but also the broadcast content.

The storage unit 513 and the CPU 514 correspond to first control means.

  First, the operation of the public server 500 will be described. The public server 500 is a server that operates to notify an emergency warning broadcast to a mobile terminal device registered in advance as shown below when a disaster occurs, but it always operates only when a disaster occurs. It doesn't have to be a server. For example, a server that is normally used for public facility reservation management, resident information management, and the like may be used for the purpose when a disaster occurs.

  When a disaster occurs, for example, when a broadcasting station 200 such as the Japan Broadcasting Corporation (NHK) transmits a broadcast wave including an emergency alert broadcast signal, image data indicating the broadcast content of the emergency alert broadcast based on the emergency alert broadcast signal. And voice data are created and transmitted to the communication unit 510 of the public server 500.

  The communication unit 510 of the public server 500 is always supplied with power and is in an operating state. Then, the reception of image data and audio data indicating the broadcast content of the emergency alert broadcast from the broadcast station 200 is monitored, and it is determined whether or not these data have been received.

To do. When the CPU 514 receives the emergency warning broadcast start signal, the CPU 514 transmits a recording start instruction signal instructing the communication unit 510 and the large capacity storage unit 511 to start the recording process. Then, the communication unit 510 that has received the recording start instruction signal transfers image data, audio data, and the like indicating the broadcast content of the emergency alert broadcast to the large-capacity storage unit 511, and the large-capacity storage unit 511 transfers the transferred data. Is encoded and compressed into compressed data of a predetermined file format, for example, MPEG format by the encoder, and the compressed data is output to the connected HDD. The HDD records the compressed data on the HD in file units.

  When the reception of image data and audio data indicating the broadcast content of the emergency alert broadcast from the broadcast station 200 is completed, the communication unit 510 transmits an emergency alert broadcast end signal notifying the end of the emergency alert broadcast to the CPU 514. When the CPU 514 receives the emergency warning broadcast end signal, the CPU 514 transmits a recording end signal instructing the recording end to the communication unit 510 and the large capacity storage unit 511. When receiving the recording end signal, the communication unit 510 and the large-capacity storage unit 511 end the recording process.

  Further, the CPU 514 does not need to notify notification information such as recorded data in which image data and audio data indicating the contents of emergency alert broadcasting are recorded among a number of pre-registered mobile terminal devices such as the mobile phone device 400. It is determined that the notification-unnecessary signal indicating that it is not transmitted to the public server 500. Then, for the portable terminal device determined not to transmit the notification unnecessary signal, the communication unit 510 reads each compressed data including the image data and the audio data recorded on the HD, and stores these compressed data on the network. To the portable terminal device via e-mail. At this time, the subject of the e-mail is set to “emergency alert broadcast occurrence” or the like so that the user can easily determine that the information is related to the emergency alert broadcast. For data transmission, it is preferable to use broadcast distribution. As a result, when data is transmitted to a large number of portable terminal devices, the communication line can be used effectively.

For example, the compressed data recorded on the HD in the large-capacity storage unit 511 is converted into the original image data and audio data. For example, the data may be decoded and decompressed and transmitted to the mobile terminal device via a network.

  On the other hand, the notification process is stopped for the portable terminal device that is determined to have transmitted the notification unnecessary signal. Further, even when the notification process is in progress, the notification process is stopped.

  In the above embodiment, e-mail is used as the recording data notification method by the communication unit 510. However, the present invention is not particularly limited to this, and for example, streaming communication may be used. Also in the case of using e-mail, in the above embodiment, the compressed data is transmitted in order to reduce the capacity of the e-mail. However, the present invention is not particularly limited to this. When streaming communication is used, the recording data may be notified during the recording process before the recording process is completed, thereby prompting the user carrying the mobile terminal device more quickly. It is possible to notify the occurrence of broadcast and its contents.

  Further, in the above embodiment, in order to make it easier for the user to determine that the information is related to the emergency alert broadcast, the subject of the e-mail is “emergency alert broadcast occurrence” or the like, but is not limited to this, for example, A predetermined fixed sentence or file indicating information related to emergency alert broadcasting may be attached to the text. In addition, if streaming communication is used, information relating to emergency alert broadcasting is included in a method of putting audio indicating information relating to emergency alert broadcasting at the beginning of streaming or in a file such as SMIL transmitted before starting streaming. There is a method to make a description that understands things.

  As described above, when the public server 500 according to the second embodiment of the present invention receives the image data and the audio data indicating the broadcast content of the emergency alert broadcast from the broadcast station 200, the public server 500 receives these data. When the communication unit 510 serving as the first broadcast receiving unit receives image data, audio data, and the like indicating the emergency alert broadcast content from the broadcast station, The storage unit 513 and the CPU 514, which are the first control means, are determined to have transmitted to the public server 500 a notification unnecessary signal indicating that notification information indicating that the data has been received is not required. Transmission of notification information to the mobile terminal device is stopped. As a result, the public server 500 can reduce the number of portable terminal devices to which notification information is transmitted, and the use of the communication line can be reduced. Therefore, when the communication line is tight when a disaster occurs, it is given to the communication line. The influence can be reduced.

  The public server 500 includes a large-capacity storage unit 511 that is a storage unit that stores at least one of image data and audio data indicating the broadcast content of the emergency alert broadcast. Accordingly, at least image data or audio data indicating the broadcast content of the emergency alert broadcast stored in the large-capacity storage unit 511 for the user who has the portable terminal device and cannot receive the emergency alert broadcast. Any one of them can be transmitted, and the emergency warning broadcast can be viewed by the user even after the fact.

  In the present embodiment, notification information such as recorded data including image data and audio data indicating the broadcast content of emergency alert broadcasting is directly transmitted to the mobile terminal device. The configuration may be such that the data is transferred to a certain other server and distributed from the transferred server in the remote place to the target portable terminal device. With such a configuration, the influence on the communication line in the disaster area can be further reduced.

  Below, the operation | movement procedure of the disaster notification system 1 is demonstrated. FIG. 8 is a flowchart showing a specific operation procedure of the public server 500 in the disaster notification system 2 of FIG.

  In the public server 500, for example, when a start instruction such as an instruction for operating the disaster notification system 2 is input by the user, the operation from step S3101 to step S3105 is started as shown in FIG.

  In step S3101, the communication unit 510 in the constantly operating state monitors reception of image data, audio data, and the like indicating the broadcast content of the emergency alert broadcast from the broadcast station 200, and determines whether these data have been received. To do. When communication unit 510 determines that it has received image data, audio data, and the like indicating the broadcast content of the emergency alert broadcast, it transmits an emergency alert broadcast start signal notifying the start of the emergency alert broadcast to CPU 514, and the process proceeds from step S3101 to step S3101. The process moves to S3102. If it is determined by the communication unit 510 that image data and audio data indicating the broadcast content of the emergency alert broadcast has not been received, the above monitoring is continued until it is determined that these data have been received.

  In step S3102, the emergency alert broadcast recording process is started. That is, the CPU 514 that has received the emergency warning broadcast start signal transmits a recording start instruction signal that instructs the communication unit 510 and the large-capacity storage unit 511 to start recording. Then, the communication unit 510 transfers image data and audio data indicating the broadcast content of the emergency alert broadcast to the large-capacity storage unit 511. The large-capacity storage unit 511 uses the encoder to transfer the transferred image data and audio data and the like. Are encoded and compressed into compressed data such as MPEG format, and the compressed data is output to the connected HDD. The HDD records the compressed data on the HD in file units.

  In step S3103, it is determined whether or not the communication unit 510 has finished receiving image data, audio data, and the like indicating the broadcast content of the emergency alert broadcast. When communication unit 510 determines that reception of the data has been completed, communication unit 510 transmits to CPU 514 an emergency warning broadcast end signal that notifies the end of the emergency warning broadcast. Then, the CPU 514 that has received the emergency warning broadcast end signal transmits a recording end instruction signal instructing the recording end to the communication unit 510 and the large capacity storage unit 511, and the communication unit 510 and the large capacity storage that have received the recording end instruction signal. The unit 511 ends the recording process, and proceeds from step S3103 to step S3104. If the communication unit 510 determines that the reception of the data has not ended, the recording process is continued.

  In step S3104, the CPU 514 displays notification information such as recorded data in which image data and audio data indicating the broadcast content of the emergency alert broadcast are recorded among a number of pre-registered mobile terminal devices such as the mobile phone device 400. It is determined that a notification-unnecessary signal indicating that notification is unnecessary is not transmitted to the public server 500. If there is a mobile terminal device that is determined not to transmit a notification unnecessary signal, the communication unit 510 reads each compressed data including audio data and image data recorded on the HD, and these compressed data Is transmitted to the portable terminal device by electronic mail via a network. Then, the operation of the public server 500 when a disaster occurs is terminated. On the other hand, for the mobile terminal device that is determined to have transmitted the notification unnecessary signal, the notification processing is stopped, and the operation of the public server 500 at the time of the disaster is terminated.

  As described above, the disaster notification system 2 according to the second embodiment of the present invention is a public server 500 that is a broadcast receiving device that receives image data, audio data, and the like indicating broadcast contents of an emergency alert broadcast from the broadcast station 200. Is a disaster system for notifying the mobile phone device 400, which is a mobile terminal device, that the data has been received. The mobile phone device 400 has an emergency alert broadcast from the broadcast station 200 by the second broadcast receiving means. When the signal is received, the second control unit transmits a notification-unnecessary signal indicating that the notification is unnecessary to the public server 500, and the public server 500 is configured such that the first broadcast receiving unit is a broadcasting station. When the image data and the audio data indicating the broadcast content of the emergency alert broadcast from 200 are received, has the first control means received the notification unnecessary signal from the mobile phone device 400? Determining out if, in the notification unnecessary signal portable telephone apparatus determines that it has received the 400, it stops the transmission of the notification information such as image data and audio data indicating the broadcast content of the emergency warning broadcast for mobile telephone 400. As a result, the number of mobile phone devices 400 that receive notification information from the public server 500 can be reduced, and the use of communication lines can be reduced. Can be reduced.

  In the first and second embodiments, the hard disk recorder 300 and the public server 500 are used as broadcast receivers. However, the present invention is not limited to this, and an emergency warning broadcast signal from the broadcast station 200 is used.
