  However, since all of the above conventional emergency broadcast receivers turn on the main power when a broadcast signal is received and output the emergency broadcast from the speaker, the hearing impaired person who cannot hear the sound. There is a problem that it is difficult to issue a warning to the user, and in particular, the contents (warning level, etc.) cannot be notified.

  The present invention has been made in view of these problems, and alerts and contents of emergency broadcasts such as emergency notification broadcasts and emergency warning broadcasts to not only healthy and visually impaired persons but also hearing impaired persons. The purpose is to be able to.

  The receiving terminal device of the present invention made to achieve such an object is for receiving a notification signal transmitted by wire or wireless in order to carry out emergency broadcasting such as the above-mentioned notification broadcasting or emergency warning broadcasting. A receiving unit, a connection terminal, a storage unit, and a control unit.

  The receiving unit is for receiving the emergency broadcast notification signal, and the connection terminal is connected to the television receiver via a cable and can output display data for image display and a command signal for control. Terminal.

  The storage unit stores display data for causing the television receiver to display a notification image corresponding to the notification signal received by the reception unit, and the control unit receives the notification signal at the reception unit. Then, display data corresponding to the notification signal is read from the storage unit.

The control unit also causes the television receiver to output display data read from the storage unit and a display command signal for displaying the notification image using the display data from the connection terminal.
For this reason, according to the receiving terminal device of the present invention, it is possible to display a notification image corresponding to the notification signal on the television receiving device in accordance with the notification signal of the emergency broadcast.

  Therefore, in a system that performs notification broadcasting or emergency warning broadcasting, a notification signal for emergency broadcasting is transmitted from a broadcasting signal transmission source (for example, a center device of a CATV system, a community broadcasting station of FM radio, or the like) by wire or wirelessly. In this way, a notification image corresponding to the notification signal can be forcibly displayed on the television receiver.

  Therefore, an alarm can be issued not only to a healthy person but also to a hearing impaired person by the display on the television receiver. When displaying the notification image on the television receiver, the notification audio data is output to the television receiver, or the notification sound or buzzer sound is output from the speaker provided in the reception terminal device. By doing so, an alarm can be issued even for a visually impaired person.

  In addition, in order for the receiving terminal device of the present invention to display the notification image on the television receiving device, display data for that purpose only needs to be stored in the storage unit, and there is no need to tune / demodulate the television broadcast signal. Compared with a general emergency broadcast receiving apparatus, it can be realized at low cost.

  Here, the connection terminal only needs to be able to output display data and a command signal to the television receiver via a cable. For example, the connection terminal is connected to HDMI (High-Definition Multimedia Interface: registered trademark) which is one of digital interface standards. If a compliant connection terminal is used, a control signal can be transmitted in addition to a video / audio signal, so that the present invention can be easily realized.

  On the other hand, if the report signal is composed of a modulated signal (such as an FM broadcast signal) obtained by modulating a carrier wave with a command information consisting of a tone signal (in other words, a DTMF signal) as in the conventional device described above, the command information can be simplified Can be set to

  Specifically, the tone signal is composed of a total of 16 types of sounds representing the numbers 0 to 9 and the symbols *, #, A, B, C, and D. Even if it is used, 16 types of command information can be set. Further, by combining these tone signals, more types of command information can be set.

  Then, when a plurality of command information is set using the tone signal in this way, when receiving the notification signal, the receiving unit demodulates the tone signal and specifies the command content from the transmission source. The control unit may select and read out a notification image corresponding to the command content from a plurality of notification images stored in the storage unit based on the command content specified by the reception unit.

  In this way, for example, as a normal image in an emergency, various guidance images such as “Please stay in the building without going outside” or “Please evacuate to the evacuation site because it is dangerous” are transmitted. It can be displayed by the original command.

  In addition, when the command content specified by the receiving unit includes a channel selection command for the specific broadcast channel, the control unit selects a channel selection command signal for causing the television receiver to select the specific broadcast channel. May be output from the connection terminal to the television receiver.

  In this way, for example, after the notification image stored in the storage unit is displayed on the television receiving device, a specific broadcast channel (such as a community channel) performing emergency broadcasting is selected by the television receiving device, More detailed information can be displayed.

  In this case, an emergency broadcast channel (community) can be provided by providing an operation unit for the receiving terminal device to set a specific broadcast channel to be selected by the control unit from the television receiving device by an external operation. Even in systems with different channels, etc., a common receiving terminal device can be used, and the receiving terminal device can be mass-produced to reduce costs.

  Next, when outputting a command signal to the television receiver via the connection terminal, the control unit determines whether or not the power of the television receiver is on via the connection terminal. If not, a power-on command signal may be output from the connection terminal to the television receiver so that the power of the television receiver is switched on.

  In this way, even when the power of the television receiver is turned off, a predetermined report image can be displayed on the television receiver by transmitting a report signal from the transmission source.

  In this case, the control unit outputs a power-on command signal from the connection terminal to the television receiver and switches the power of the television receiver to the ON state. It is preferable to output a power-off command signal from the TV to the television receiver so that the television receiver is turned off.

  Furthermore, the receiving terminal device of the present invention is provided with an update command receiving unit that receives an update command for display data transmitted from a transmission source or another external terminal, and the control unit is updated by the update command receiving unit. When the command is received, the display data stored in the storage unit may be updated according to the update command.
