Description
The present invention relates to a digital emergency broadcasting apparatus and a method thereof, and more particularly, to a digital emergency broadcasting apparatus and a method for effectively delivering an audio-visual guidance emergency broadcasting in a building or a public place at an economic cost.
Basically, in a building or public place over a certain size, when an emergency occurs (disaster / disaster such as fire or earthquake), emergency signals or audio announcements are required to inform the public of the emergency.
Although audio information such as an emergency bell or sirens is effective for the purpose of notification of such an emergency occurrence, such a simple notification of an emergency situation may cause confusion due to the lack of accurate information. On the other hand, there are cases in which an emergency announcement is notified by an audio announcement, but in this case, it is necessary to provide a guide announcement prepared in advance for an emergency situation or to be broadcasted by a manager. It may be difficult to pinpoint the exact situation, as the surrounding noise may be loud, the audio output may ring, or the audio may not be clearly heard. Therefore, after the emergency notification, additional damages are frequently caused during the evacuation process.
In addition, in the case of an emergency notification based on such an audio signal, it is increasingly difficult for the hearing impaired, the hearing impaired, or the foreigner to effectively respond because they do not know the exact emergency contents.
Therefore, in addition to these audio signals, there is a growing need to deliver information on emergency situations through visual images. Therefore, emergency broadcasting can be provided through a digital TV or a corresponding video device installed for various purposes in various environments. The system to make it appear.
For example, the Republic of Korea Patent No. 10-0572056 'disaster broadcasting system using a wired broadcasting network' proposes a forced broadcasting system that can deliver emergency broadcasts by remotely controlling the channel of the TV.
1 is a configuration diagram of one embodiment of a conventional emergency broadcasting system, and shows a configuration of Korean Patent No. 10-0572056.
As shown in FIG. 1, a
Then, the general broadcast signal and the control signal provided through the
When configuring an emergency broadcast using a TV as described above, an expensive TCU must be provided for each TV, and an emergency broadcast (control signal) having a different modulation and demodulation method must be sent so that it can be distinguished from a general broadcast. It is very high, so it is not easy to apply, and it is not suitable as a countermeasure in urgent emergency because each TV must be controlled directly by the operator in the broadcasting room.
FIG. 2 is a configuration diagram of another embodiment of the conventional emergency broadcasting system, and illustrates the case where emergency broadcasting is configured by using an IPTV or a digital cable broadcasting system, which has recently been used as a broadcasting system capable of bidirectional communication.
As shown in FIG. 2, when the
However, such an emergency broadcasting system requires a service subscription, continuous usage fees, and an expensive set-top box installation, so it is cost-effective to apply to a TV configuration that provides information or advertisements to public places or places with many users. It is inadequate in management.
On the other hand, the basic MATV (Master Antenna TV) broadcasting network system is installed in most public places such as public offices, public institutions, department stores, hotels, airports, terminals, apartments, and lodgings where many people gather. However, in the case of the MATV broadcasting network system, despite the high necessity of guiding according to emergency situations such as fire, terrorism, and earthquake, emergency broadcasting is not performed due to cost or administrative difficulties, leading to serious damage.
It is therefore an object of the present invention to solve the problems of the prior art as described above.
