FIG. 3 is a flowchart illustrating a method for receiving a home-type DMB disaster broadcast of a home-type DMB disaster broadcast receiving apparatus according to an embodiment of the present invention.

The home-type DMB disaster broadcast receiving apparatus (hereinafter, also referred to as a DMB receiving apparatus) separately receives two or more DMB (Digital Multimedia Broadcasting) disaster messages transmitted from a plurality of channels at step S10.

Specifically, the DMB receiving apparatus receiving the digital disaster broadcast receives the high-frequency radio signal of the first channel, that is, the DMB broadcasting signal, through the transmitting / receiving antenna.

The DMB broadcasting signal is transmitted in the format shown in FIG. 4, and the DMB broadcasting signal may include a digital disaster announcement signal.

4 is a diagram for explaining a format of a DMB broadcast signal used in an embodiment of the present invention.

As shown in FIG. 4, the channel through which the digital disaster announcement announcement signal is transmitted may be a fast information channel (FIC) (b).

In this case, the fast information channel (FIC) can be checked to check whether there is a digital disaster announcement signal.

 When a disaster message is transmitted through a fast information channel (FIC), a digital disaster announcement announcement signal may be transmitted via a predetermined Fast Information Group (FIG) type 5 extension 2.

FIG 5 Extension 2 (FIG 5/2) consists of FIG header and FIG data.

The FIG header consists of a 3-bit FIG TYPE field (set to "101" in case of a disaster message) and a length field (5 bits).

The FIG data includes the digital disaster broadcast validity data indicating the validity of the digital disaster broadcast data and the detailed information of the disaster message. For example, it is possible to determine whether the digital disaster broadcast data is valid by checking the D1 field. For example, it can be determined that digital disaster broadcast data is provided only when D1 = 1. That is, when D1 = 1, the digital disaster broadcast data is inserted instead of the padding, and digital disaster broadcast data can be extracted and displayed on the DMB receiver.

Meanwhile, a unique serial number is assigned to the received disaster message, thereby confirming the identity of the message transmitted through each medium by checking the serial number included in the message received by the DMB disaster message receiving apparatus. Accordingly, when a digital disaster broadcast message having the same serial number is received, only the first received digital disaster broadcast message is output, and a message having the same serial number received subsequently is discarded.

Although the serial number is provided as an example for confirming the identity of the digital disaster broadcast message, the present invention is not limited to the serial number, but it is sufficient that the identifier is capable of distinguishing whether or not the digital disaster broadcast message is identical And it is obvious to those skilled in the art that it can be modified into various forms, so that specific examples thereof are omitted.

In step S10, when two or more DMB (Digital Multimedia Broadcasting) messages transmitted from a plurality of channels are distinguished from each other and a plurality of received disaster messages are received, the disaster information for the disaster area and the disaster class is extracted from the received two or more disaster messages S20).

In the case of the FIG type 5 extension 2 (FIG 5/2), disaster information can be extracted from the information included in the FIG data. The disaster information may be a serial number assigned by a disaster broadcasting organization or a request issuing organization for a disaster broadcast or may include information on a disaster area and a disaster level as information contained in FIG data according to a format defined by the agency.

Table 1 shows an example of the length and type of the information included in the FIG data.

No length division type  One 1 byte CMD  2 30 byte Message Title [string]  3 1 byte Priority of messages [uint]  4 1 byte Disaster type [uint]  5 4 bytes Dispatch time [DateTime]  6 1 byte Type of area issued [uint]  7 1 byte Number of regions issued [uint]  8 4 bytes Issued user ID [uint]  9 2 bytes Message Contents Length  10 n byte Message contents [string]  11 200 bytes Message content for SMS [string]  12 2 bytes Message content length for TTS  13 n byte Message content for TTS [string]  14 1 byte Information about where to send [enum]  15 1 byte Type of dispatch equipment [enum]  16 1 byte Command mode [byte]  17 1 byte Interval [byte]  18 1 byte Repeat statement [byte]  19 1 byte Broadcaster ID [uint]  20 1 byte Progress [bool]  21 4 bytes Number of mapped geographic and device information  22 4 bytes Region or Equipment ID (FK) [uint]  23 30 byte The name of the connected region or device [string]  24 1 byte Region / Equipment Information Category [uint]

The data format shown in Table 1 is an example, but the present invention is not limited thereto.

A disaster message to be output is selected by referring to the extracted disaster information (S30).

If the disaster area of the disaster message is a pre-set broadcast setting area al, an upper layer of the broadcast setting area a1, and a lower layer of the broadcast setting area al, it is determined that the disaster message is an output target message. For example, if the preset broadcast setting area a1 is set as Yeongdeungpo-gu, the disaster messages in Yeouido-dong, which is a lower layer of Seoul and Yeongdeungpo-gu, Yeongdeungpo-gu,

If disaster broadcasting in Seoul and Yeongdeungpo-gu disaster broadcasting are all received, check the disaster level of each received disaster broadcast and output the disaster broadcast in the order of higher disaster level, that is, the disaster is more serious.

In other words, when there are a plurality of disaster messages determined to be output destination messages, it is determined to preferentially output a message having a high disaster level. The disaster grade may include, for example, an alert and an alert, which means a higher level of disaster rating than the alert.

Examples of alarms and warnings are illustrated in Table 2.

The above disaster type and grade can be indicated by code information.

After step S30, the selected disaster message is output (S40).

The user is informed of the occurrence of a disaster by blinking a lamp to notify of occurrence of a disaster, sounding a siren to notify of occurrence of a disaster, or displaying a message of a predetermined message on a display window. For example, code information corresponding to the strong wind warning, compares the received code with a previously stored code analysis value, and outputs a phrase stored in advance, which matches the code analysis value.

In addition, when there is a disaster image, a method of receiving a disaster image can be displayed on a display window or a disaster image receiving address can be provided to a predetermined terminal.

After outputting the disaster message, the receiving apparatus continuously monitors the channel transmitting the disaster message, and if the transmission of the message having the same identifier stops at a predetermined time, for example, one minute or more, .

More specifically, it is checked whether a predetermined time has elapsed when a digital disaster announcement announcement signal is not received.

If the digital disaster announcement notification signal is not continuously received even after a predetermined time has elapsed, it is possible to receive a digital disaster broadcast signal for a DMB relay station currently responsible for transmitting the digital disaster broadcast, a disaster at a digital disaster broadcast transmission agency, It should be able to confirm it to the higher authority.

In order to ensure that the digital disaster broadcasting system is normally transmitted even when an emergency occurs unexpectedly, it is necessary to identify the path or apparatus in which a failure has occurred so as to normally operate the digital disaster broadcasting system, Is achieved by a DMB disaster message receiving apparatus according to the present invention.

If the DMB disaster message receiving device does not receive the digital disaster announcement signal for a predetermined period of time, the DMB disaster message receiving device generates a signal indicating that the digital disaster message is not received, modulates the signal, and transmits the signal to the CDMA base station via the RF transmitter.

The CDMA base station transmits the received CDMA modulated signal to a predetermined upper level authority.

In addition, the DMB disaster message receiving apparatus may diagnose the status of each of the devices provided in the DMB disaster message receiving apparatus by itself or at a request from an upper level institution, generate a diagnosis result, and report the status to the higher level institution. Receives an apparatus diagnosis signal from a measuring apparatus provided in each apparatus according to an instruction from a higher-level organ or a control unit, generates it as a receiving apparatus diagnosis signal, modulates it by CDMA, and reports it to an upper authority through the RF transmitting unit.

Meanwhile, if a digital disaster announcement announcement signal is not received from the first channel for a predetermined time, the digital disaster alert notification signal that can be transmitted from another channel may be monitored.

Specifically, when a digital disaster announcement announcement signal is not received for a predetermined period of time, a channel other than the first channel is sequentially scanned according to a predetermined rule, and it is checked whether or not a digital disaster announcement announcement signal is included in each channel .

If the digital disaster announcement announcement signal is included in the specific channel, the digital disaster alert notification signal is continuously received in synchronization with the channel, and a channel including the digital disaster announcement announcement signal and the channel And reports it to the parent organization.

In order to generate a rule for scanning a channel other than the first channel, the DMB disaster message receiving apparatus may have a separate apparatus or algorithm.
