By the way, in preparation for the Tokai earthquake, which has been particularly feared in recent years, the Japan Meteorological Agency is promoting the introduction of earthquake early warning in addition to the conventional emergency warning broadcast as emergency disaster prevention information to be notified via television.
Conventional emergency warning broadcasting is designed to automatically transmit a receiver with a specific function by sending a signal that also serves as an alarm sound from a broadcasting station to convey disaster information even at midnight. A model that automatically turns on the power has also been developed.
NHK broadcasts tsunami warnings and warnings of large-scale earthquakes only in the following three cases, which have a serious impact on human life and property, on all TV and radio broadcast waves.
-When a warning declaration for a Tokai earthquake is issued-When a tsunami warning is issued-When the head of a local government requests an evacuation order, etc.

On the other hand, the Earthquake Early Warning reports the P wave at the time of the earthquake, predicts the magnitude and epicenter of the earthquake, and announces it several seconds to several tens of seconds before the large shaking S wave comes. Announcement is scheduled when the seismic intensity is predicted to be less than 5.
The TV and radio are not automatically switched on during the broadcast, but it is expected that the damage of the earthquake can be reduced using a short amount of time.

However, emergency disaster prevention information display systems such as those shown in Patent Documents 1 and 2 do not assume emergency earthquake warnings that cannot be distinguished from normal broadcasts, and deal with display delays in digital broadcasting, which is currently an issue. It is impossible to do.
In other words, even if the receiver receives the earthquake early warning, when receiving digital broadcasts, the compressed received data is processed by the decoder and video processing unit, expanded into image data, and then controlled by the display processing unit. Since it is displayed on the display panel unit such as a liquid crystal display, it takes several seconds until the alarm is actually transmitted from the receiving device.

A similar system can be constructed for analog broadcasting as compared to the above digital broadcasting, but since analog broadcasting does not send compressed broadcasts, it does not require time for decompression and is displayed in comparison with digital broadcasting. However, in recent years, digital broadcasts have also compressed data when sending emergency earthquake warnings as emergency warning signals. However, attempts are being made to shorten the time until display, and to superimpose the earthquake early warning data on the electronic program guide data.
However, even if such an attempt is made, until the emergency alert broadcast itself is displayed, the user cannot recognize the occurrence of the emergency disaster prevention case as before, and it is dangerous to the user as soon as 1 second. It is not sufficient as a system that is required to make people recognize.

  Further, as described in Patent Document 3, there is a possibility that such a problem can be avoided if a microcomputer is used. However, a highly accurate acceleration sensor and an individual program are required, and the microcomputer is installed for 24 hours. It is necessary to always start up, and a big problem remains in terms of cost and energy saving, which is a factor that hinders popularization.

  In the present invention, by using an OSD (on-screen display) function in a television such as a liquid crystal television, it is possible to instantly display an emergency earthquake warning such as an earthquake and give an alarm, thereby solving the above problem. The purpose is that.

Therefore, the present invention provides a television having the following emergency disaster prevention information reporting function.
(1) In a television that displays an image signal received by a digital broadcast tuner via a decoder, a video processing unit, and a display processing unit, when the digital broadcast tuner receives image data to be compressed, an emergency information identification signal And an emergency information identification signal output means for directly outputting an OSD control unit for controlling the OSD display of the display processing unit based on the emergency information identification signal, and an emergency based on the received compressed image data A TV that displays disaster information.
(2) In a television that displays an image signal received by a digital broadcast tuner via a decoder, a video processing unit, and a display processing unit, the digital broadcast tuner receives received data in which emergency disaster information is superimposed on electronic program guide data. , An emergency information identification signal output means for outputting an emergency information identification signal is provided. Based on the emergency information identification signal, the OSD control unit for controlling the OSD display of the display processing unit is directly operated and received. A TV that displays emergency disaster information.
(3) In the television of (1) and (2) above, an emergency warning with a predetermined voice is stored, and when the digital broadcast tuner receives the compressed data, the digital broadcast tuner receives a predetermined volume from the speaker. A TV equipped with a voice processing device that reports emergency alerts by voice.

  According to the television of the present invention, when the digital broadcast tuner receives the compressed data or when receiving the reception data in which the emergency disaster information is superimposed on the electronic program guide data, without processing by the decoder and the video processing, It is possible to display emergency disaster information instantaneously by directly operating the OSD control unit of the display processing unit, and it is possible to secure time until the arrival of the main shock.

  In addition, when an emergency alert is recorded in a predetermined voice and the digital broadcast tuner receives the compressed data, if the emergency alert is reported from the speaker at a predetermined volume, the TV screen is not watched. However, it can immediately recognize that an emergency disaster bulletin has been issued.

The whole block diagram at the time of applying this invention to a liquid crystal television is shown. The whole block diagram of the conventional liquid crystal television is shown.

FIG. 2 is an overall block diagram of a conventional general liquid crystal television, and an image signal received from a receiving device including a digital broadcast tuner 1 is processed by a decoder 3, a video processing unit 4, and a display processing unit 5. Are displayed on the display panel 7. In the decoder 3, the compressed moving image data is expanded, stored in a memory (not shown) in the video processing unit 4, expanded, and converted into a format suitable for the display panel in the display processing unit 4, and then displayed on the display panel 7. It has come to be.
Therefore, as described above, since it is necessary to decompress the compressed data from the reception of the digital broadcast to the display, it takes a longer time to display than when receiving the analog broadcast.
The display processing unit 5 includes an OSD (on-screen display) processing unit 6 that displays channel display, volume display, various setting states, and the like, and the OSD is superimposed on the display panel 7 under the control of the microcomputer 8 to instantaneously. It is possible to display.

  By the way, as mentioned above, there are two types of emergency disaster broadcasts that broadcast stations broadcast during disasters such as major earthquakes and tsunamis: emergency earthquake bulletins and emergency warning broadcasts. Sends emergency information. On the other hand, emergency alert broadcasting is a broadcast that is temporarily performed after a broadcasting station precedes a special signal called an emergency alert signal, and is a kind of data broadcasting.

  In the case of digital broadcasting, the emergency alert signal is transmitted as data called an emergency alert broadcast identifier, so that it can be distinguished from ordinary broadcast, but the current emergency earthquake bulletin cannot be distinguished from ordinary broadcast. For this reason, in terrestrial digital broadcasting, video and audio data are compressed and transmitted with respect to the current analog broadcasting, and restored by a home receiver, so that they are displayed with a delay of 2 to 5 seconds.

Therefore, a new attempt to send uncompressed data at the time of emergency earthquake bulletin transmission has been studied, but in order to display the received video data itself without the need for decompression, the decoder 3 and the video processor 4 In addition, although it is necessary to perform processing by the display processing unit 5 and a quick display is required as much as possible, it takes a certain amount of time to display in the earthquake early warning.
In the present invention, when the information that the received data is uncompressed is obtained, the emergency information is issued before the emergency earthquake warning can be displayed using the OSD function shown above. Can be quickly displayed, and FIG. 1 shows an embodiment.

In other words, if the digital broadcast tuner 1 receives information that the received data meaning the reception of the earthquake early warning is uncompressed, the digital broadcast tuner 1 outputs the information as an emergency information identification signal 10 and transmits it to the microcomputer 8. The microcomputer 8 displays the emergency information set in advance by the emergency information identification signal 10 inputted, so that the OSD processing of the display processing unit 5 is not performed by the decoder 3, the video processing unit 4, and the display processing unit 5. The unit 6 is directly controlled, and the emergency information is instantaneously displayed on the display panel 7 so that the user can recognize the occurrence of the earthquake.
In addition, since it is necessary to display the original emergency earthquake warning after the user recognizes the occurrence of the earthquake through the OSD display and to obtain detailed information about the earthquake, it is desirable that the display time of the OSD display be several seconds. Conceivable.

In recent years, distribution of emergency disaster information using the G guide, which is an electronic program guide, has also been considered in the earthquake early warning. , The emergency information identification signal 10 can be output from the digital broadcast tuner 1, and the user can quickly recognize the occurrence of the earthquake.
Furthermore, it is possible to output the emergency information identification signal 1 from the digital broadcast tuner 1 based on the received emergency alert broadcast identifier even when receiving the emergency alert broadcast so far. The OSD processing unit 6 of the display processing unit 5 is directly controlled by the emergency information identification signal 10 without being processed by the decoder 3, the video processing unit 4, and the display processing unit 5, and an emergency warning is instantly displayed on the display panel 7. It is possible for the user to quickly recognize the occurrence of a disaster.

Although not shown, the microcomputer 8 that has received the emergency information identification signal 10 separately stores an alarm by voice in the memory when the emergency information is displayed on the OSD, and reports a uniform alarm as voice. You may make it do.
In addition, although the liquid crystal television was demonstrated in the Example, it is clear that the television which can apply this invention is not restrict | limited to a liquid crystal television.

  As described above, according to the present invention, when an emergency disaster broadcast is received, the received signal is not processed by the decoder and the video processing 4, but is displayed by directly operating the OSD function of the display processing unit. Emergency disaster prevention information can be instantly displayed and alerted, and evacuation information and the like can be reported to many households at appropriate timing, making it possible to spread television as an effective disaster prevention measure.
