Description

  The present invention relates to a technique for quickly displaying an emergency message by reducing a time delay on a digital broadcast receiving apparatus being viewed when detecting information on an earthquake early warning.

  In the event of an emergency such as a disaster, an emergency broadcast from a television or radio broadcasting station, such as an emergency earthquake warning / emergency warning broadcast (EWS) / temporary news, or e-mail (e-mail) notification service via the Internet For example, it is notified that it is an emergency.

  In the case of digital broadcasting (TV), since video / audio is transmitted after being encrypted / compressed, it takes time for data processing when transmitting from the broadcasting station and when receiving it on the TV and returning to the original video / audio. It takes.

  In digital television, when data other than the broadcast data transmitted by the program being viewed (including broadcast programs of other channels) is to be displayed on the screen, the switching process takes about several seconds.

  In general, emergency information can be viewed and heard only by a receiver corresponding to the medium to which the information is transmitted, such as a television / radio or a personal computer in the above example.

  Also, in the case of nationwide net broadcasting such as satellite broadcasting, in the case of local earthquake information, the viewer will continue to watch without knowing that it is an emergency.

  Up to now, the power is off, but the power is not completely turned off. When the emergency alert broadcast is detected with the reception function alive, the power is automatically turned on and the received emergency broadcast Video / audio was notified to the user, a dedicated emergency broadcast receiver was used, or an emergency program was broadcast in the form of interrupting a television or radio program transmitted from a local broadcasting station.
