A tuner 102, an audio output unit 103, a video display unit 104, an operation unit 105, a communication unit 106, an input unit 107, a storage unit 108, and a determination unit 109 are connected to the control unit 101, respectively.

  The operation unit 105 has a plurality of operation buttons (not shown). By operating each operation button, the power to the main unit 10 is changed, the channel is changed, the volume output from the audio output unit 103 is adjusted, and the like. it can.

  An antenna 102a is connected to the tuner 102, and a TV broadcast signal (for example, a TV broadcast signal related to terrestrial digital broadcast, BS digital broadcast, etc.) is received from a TV broadcast station via the antenna 102a. The TV broadcast signal includes an emergency warning broadcast activation flag that is transmitted when broadcasting an emergency warning broadcast related to a disaster such as an earthquake.

  The emergency warning broadcast activation flag is included in TMCC (Transmission and Multiplexing Configuration and Control) received by the tuner 102. When the TV broadcast station transmits the emergency alert broadcast activation flag as 1, the television receiver 1 is notified of the start of emergency alert broadcast.

  The tuner 102 demodulates the received TV broadcast signal. Thereafter, an audio signal is transmitted from the control unit 101 to the audio output unit 103, and audio based on the audio signal is output from the audio output unit 103. In addition, a video signal is transmitted from the control unit 101 to the video display unit 104, and a video based on the video signal is output from the video display unit 104.

  An antenna 106 a is connected to the communication unit 106.

An external device such as the hard disk device 60 is connected to the input unit 107 via a cord 60a.

  The storage unit 108 includes, for example, an EEPROM or the like, and stores an operation program and various data of the main body unit 10. The data stored in the storage unit 108 includes a user's home schedule that is input in advance. The home schedule setting screen S (see FIG. 3) is displayed on the video display unit 104 using the operation unit 105 or the cross key 30a or the character key 30b of the remote controller 30, and the user inputs the home schedule. As a result, the home schedule of the user is stored in the storage unit 108.

  FIG. 3 is an image diagram showing a home schedule setting screen S displayed on the video display unit 104 of the television receiver 1. The date, time zone, and home status for each of users A to C are shown in order from the left column. In the column of user names, hatched portions indicate that the users A to C are at home, and blank portions indicate absence. For example, all users A to C are scheduled to stay at home from 1 am to 2 am on October 3, 2013, and all are scheduled to be absent from 11:00 am to 12:00 am It is shown that.

  The determination unit 109 determines whether the users A to C are at home based on the at-home schedule stored in the storage unit 108. For example, the determination unit 109 determines that all of the users A to C are absent from 9:00 to 17:00 on October 3, 2013 (see FIG. 3).

  FIG. 4 is a flowchart showing the display operation of the emergency warning broadcast of the television receiver 1. The television receiver 1 is in a standby state. Here, the standby state indicates a state where the screen of the video display unit 104 is not displayed and an emergency warning broadcast can be received by the tuner 102. In addition, the input of the home schedule by the user has been completed.

  In step # 1, it waits until a notification signal for notifying the start of emergency alert broadcasting is received (the emergency alert broadcast activation flag included in the notification signal becomes 1). When the notification signal is received, the process proceeds to step # 2. In step # 2, whether or not the users A to C are at home is determined by the determination unit 109 on the basis of the at-home schedule input in advance. If even one of the users A to C is at home (for example, in FIG. 3, the user B is at home during the time period from 8 am to 9 am on October 3, 2013), step # 3 Migrate to On the other hand, when all the users A to C are absent (for example, in FIG. 3, the time zone from 9:00 to 17:00 on October 3, 2013), the emergency alert broadcast display operation is terminated and the standby state is changed. Maintained.

  In step # 3, a notification screen P as shown in FIG. 5 is displayed on the video display unit 104. The notification screen P includes, for example, a message that “emergency warning broadcasting will start” and a diagram depicting a house and a telephone pole swaying due to an earthquake. The notification screen P notifies that the emergency alert broadcast will be displayed on the video display unit 104 soon (several seconds later). At this time, a beep sound or the like may be output from the audio output unit 103.

  Thus, before the emergency warning broadcast is displayed on the video display unit 104, the user can recognize that an emergency situation due to a natural disaster or the like has occurred. Therefore, the user can quickly prepare for the evacuation action. At this time, only the beep sound may be output by the audio output unit 103 without displaying the notification screen P. As a result, the user pays attention to the television receiver 1 so that the emergency warning broadcast can be reliably viewed from the beginning.

  In step # 4, the area indicated by the area code of the emergency information descriptor included in the PMT (Program Map Table) in the transport stream included in the main part of the emergency alert broadcast received by the television receiver 1 is the television receiver. It is judged whether it corresponds to 1 installation area. When the area indicated by the area code corresponds to the installation area of the television receiver 1, the process proceeds to step # 5. The installation area of the television receiver 1 is set in advance by the user by operating the remote controller 30 or the operation unit 105. The emergency information descriptor is a description of necessary information and functions as an emergency warning signal.

  If the area indicated by the area code does not correspond to the installation area of the television receiver 1 in step # 4, the process proceeds to step # 13. In step # 13, the video display unit 104 displays that the area does not correspond to the emergency alert broadcast target area. As a result, the user can easily recognize that an emergency due to a natural disaster or the like has occurred outside the area where the user resides. And the user can confirm the occurrence situation of a natural disaster etc. with another broadcast program etc. Then, the television receiver 1 ends the emergency alert broadcast display operation and returns to the standby state.

  In step # 5, the emergency alert broadcast is displayed on the video display unit 104. Thereby, the user can view the emergency alert broadcast. In step # 6, it is determined whether the hard disk device 60 is powered on. If the hard disk device 60 is powered on, the process proceeds to step # 7. If the power is not powered on, the process proceeds to step # 8.

  In step # 7, recording of an emergency alert broadcast is started by the hard disk device 60. As a result, it is possible to prevent an emergency warning broadcast from being overlooked. At this time, it is possible to perform so-called chasing playback when the recorded program to be played back is being broadcast at the playback start timing. Thereby, the user can acquire evacuation information etc. reliably.

  In the event of a natural disaster such as an earthquake, the broadcasting station may be damaged, and the display of the emergency warning broadcast may be interrupted on the channel that the user is watching. Therefore, in step # 8, it is determined whether or not the display of the emergency warning broadcast on the video display unit 104 has been interrupted. When the display of the emergency alert broadcast is interrupted, the process proceeds to step # 9, where a channel for broadcasting the emergency alert broadcast is searched and switched. Thereby, the user can know evacuation information etc. reliably at the time of disasters, such as a tsunami and an earthquake.

If the display of the emergency alert broadcast is not interrupted in step # 8, step # 10
Migrate to In step # 10, it is determined whether an end signal has been received (whether the emergency warning broadcast activation flag has become 0). When the end signal is received, the process proceeds to step # 11. In step # 10, if the end signal has not been received, the process returns to step # 8, and steps # 8 to # 10 are repeated.

  In step # 11, the emergency alert broadcast is finished and the screen of the video display unit 104 is not displayed. In step # 12, recording by the hard disk device 60 is stopped.

  According to the present embodiment, when an emergency warning broadcast is received in a standby state, the emergency display is displayed on the video display unit 104 when one of the users A to C is at home according to the determination of the determination unit 109. Thereby, the user at home can surely view the emergency warning broadcast.

  On the other hand, when the emergency warning broadcast is received in the standby state, if all the users A to C are absent by the determination of the determination unit 109, the video display unit 104 maintains the non-display state. Thus, the emergency alert broadcast is not displayed on the video display unit 104 when all of the users A to C are absent. Therefore, the power consumption of the television receiver 1 can be reduced.

  In addition, when all of the users A to C are absent, the emergency warning broadcast is not displayed on the video display unit 104. Therefore, in the case where the emergency warning broadcast is broadcast but the evacuation is not necessary, the nuisance of the neighborhood due to noise is prevented. can do. In addition, when an earthquake occurs so that the furniture in the house collapses when all the users A to C are absent, it is possible to prevent a fire of the television receiver 1 that is more likely to occur than in the standby state.

  Further, the home schedule of the users A to C input in advance is stored in the storage unit 108, and the determination unit 109 determines whether the users A to C are at home based on the home schedule. Thereby, the time slot | zone which does not display emergency alert broadcast on the video display part 104 can be preset. Therefore, the usability of the television receiver 1 can be improved.

  Further, when a notification signal for notifying the start of the emergency alert broadcast is received, a screen display or a sound notification operation is performed until the emergency alert broadcast is displayed. Thus, before the emergency warning broadcast is displayed on the video display unit 104, the user can recognize that an emergency situation due to a natural disaster or the like has occurred. Therefore, the user can quickly prepare for the evacuation action.

  Further, when the emergency alert broadcast cannot be received while being displayed on the video display unit 104, a channel for broadcasting the emergency alert broadcast is searched and switched. Thereby, the user can know evacuation information etc. reliably at the time of natural disasters, such as a tsunami and an earthquake.

  In the first embodiment, the emergency alert broadcast is displayed on the video display unit 104 after receiving a notification signal notifying the start of the emergency alert broadcast (“YES” in step # 1 in FIG. 4) (FIG. 4). If the television receiver 1 cannot receive the emergency warning broadcast until step # 5), the channel for broadcasting the emergency warning broadcast may be searched and switched. As a result, the user can surely view the emergency warning broadcast.
