  FIG. 6 is a flowchart showing an example of the operation of the broadcast receiver 1 (mainly the CPU 15). Here, for convenience, a case where emergency display information is stored in advance in association with registered word information in the registered information storage unit 161 will be described. First, the importance level determination unit 152 determines whether importance level information has been received via the control signal reception unit 10 (S101). If it is determined that the importance level information has not been received (NO in S101), the process enters a standby state. If it is determined that the importance level information has been received (YES in S101), whether the importance level information received in step S101 by the importance level determination unit 152 is within the preset importance level range or not. (In this case, whether the importance indicated by the importance information (alert_priority) is within the range of “1” to “11”) is determined (S103).

  If it is determined that it is not within the preset importance range (NO in S103), the process returns to step S101, and the processes after step S101 are repeatedly executed. If it is determined that it is within the preset importance level (YES in S103), the character acquisition unit 153 acquires character string information (S105). Then, the count unit 154 counts the number of appearances of the registered word included in the character string information acquired in step S105 and stored in the registration information storage unit 161 (S107). Next, whether or not the number of appearances counted in step S107 by the number determination unit 155 is greater than or equal to a preset threshold number (here, 10 times) is determined for each registered word stored in the registration information storage unit 161. (S109).

  If it is determined that the number of appearances is not greater than or equal to the threshold number (NO in S109), the process returns to step S105, and the processes after step S105 are repeatedly executed. If it is determined that the number of appearances is greater than or equal to the threshold number (YES in S109), the display control unit 156 determines that the number of appearances is greater than or equal to the threshold number in step S109, and the registered word stored in the registration information storage unit 161 The emergency display information corresponding to is generated by reading from the registered information storage unit 161 (S111). Then, the display control unit 156 displays character information corresponding to the emergency display information generated in step S111 on the display 141 (S113), and the process is terminated.

  FIG. 5B is a screen diagram showing an example of the emergency information display screen displayed in step S113 of the flowchart shown in FIG. On the emergency information display screen 330, an emergency item display unit 331 is displayed at the top of the screen, a registration information display unit 332 is displayed at the approximate center of the screen, and a confirmation button 333 is displayed at the bottom of the screen.

  The emergency item display unit 331 displays emergency item information indicating the contents of the emergency broadcast. Here, “Fire has occurred. Please evacuate.” Is displayed. That is, the emergency information display screen 330 shown in FIG. 5B is determined to be equal to or more than the threshold number in step S109 of the flowchart shown in FIG. 6, and the registered word stored in the registered information storage unit 161 is “fire. This is a screen that is displayed when the message indicates “occurrence” (for example, “fire” or the like).

  The registered information display unit 332 displays emergency display information corresponding to the emergency item displayed on the emergency item display unit 331. That is, it is determined in step S109 in the flowchart shown in FIG. Here, in the registration information display section 332, “evacuation destination (location)” and “evacuation destination (phone number)” are displayed as emergency display information.

  The confirmation button 333 is a button that is pressed when the user confirms the content displayed on the emergency information display screen 330 and displays the video received via the broadcast receiving unit 11 on the display 141.

  Thus, emergency display information, which is information to be displayed on the display 141 when an emergency broadcast is received, is stored in the registered information storage unit 161 in advance in association with registered word information for determining the content of the emergency broadcast. The control signal receiving unit 10 receives importance level information (alert_priority) that is information indicating the degree of importance of emergency broadcasting. Whether the importance level information received by the control signal receiving unit 10 is within a preset importance level range (here, whether alert_priority is within a range of “1” to “11”). Is determined, and character string information included in the emergency broadcast is acquired via the control signal receiving unit 10 when it is determined that the value is within the preset importance range. Then, the number of appearances of the registered word included in the acquired character string information and stored in the registration information storage unit 161 is counted for each registered word, and the counted number of appearances is a preset threshold number (here, 10 times) or more is determined for each registered word. Further, when it is determined that the number of times is equal to or greater than the threshold number, emergency display information corresponding to the registered word determined to be equal to or greater than the threshold number is read from the registered information storage unit 161 and displayed on the display 141. Appropriate information can be notified for each user according to the contents of the emergency broadcast.

  That is, emergency display information, which is information displayed on the display 141 when an emergency broadcast is received, is stored in the registered information storage unit 161 in advance in association with registered word information for determining the contents of the emergency broadcast. When the importance level information received by the control signal receiving unit 10 is determined to be within the preset importance level range (here, alert_priority is within the range of “1” to “11”). In addition, the character string information included in the emergency broadcast is acquired via the control signal receiving unit 10, and the number of appearances of the registered word included in the acquired character string information and stored in the registration information storage unit 161 is registered. The emergency display information corresponding to the registered word that is counted for each word and determined that the counted number of appearances is equal to or greater than the threshold number (here, 10 times) is the registered information storage unit 16. Therefore, the emergency display information that the user desires to display on the display 141 is associated with the registered word information for determining the content of the emergency broadcast in the registered information storage unit 161. By storing in advance, it is possible to notify appropriate information for each user according to the contents of the emergency broadcast.

  In addition, since an operation input from the user is received via the operation unit 18, emergency display information and registered word information are generated based on the received operation input and stored in the registration information storage unit 161. The emergency display information that the user desires to display on the display 141 can be stored in advance in the registered information storage unit 161 in association with the registered word information for determining the content of the emergency broadcast. Depending on the content, more appropriate information can be notified for each user.

  Furthermore, since the registered information storage unit 161 stores earthquakes, fires, and floods as registered words, the registered information storage unit 161 stores words that are highly important for the user as registered words. Convenience can be improved.

  In addition, evacuation destination location information that is information indicating the location of the evacuation destination and evacuation destination telephone number information that is information indicating the telephone number of the evacuation destination are stored in the registration information storage unit 161 as emergency display information. For this reason, information that is highly important for the user is stored in the registered information storage unit 161 as emergency display information, so that convenience can be further improved.

  Further, information is received by the control signal receiving unit 10 via a cable, and the control signal receiving unit 10 sets a specific frequency band that is different from the frequency band of the broadcast signal (= OOB (Out Of Band): (70 to 130 MHz), the importance level information is received, so that the importance level information can be reliably received.

The present invention can also be applied to the following forms.
(A) In the present embodiment, the case where the broadcast receiving apparatus is the broadcast receiver 1 that receives an analog broadcast and a digital broadcast has been described. However, the broadcast receiving apparatus may receive one of the digital broadcast and the digital broadcast. .

  (B) In the present embodiment, the CPU 15 functionally includes a registration information generation unit 151, an importance level determination unit 152, a character acquisition unit 153, a count unit 154, a frequency determination unit 155, and a display control unit 156. However, at least one functional unit among the registration information generation unit 151, the importance determination unit 152, the character acquisition unit 153, the count unit 154, the number determination unit 155, and the display control unit 156 is a circuit or the like.
