In addition, metadata is inserted to transmit the received disaster broadcast information, and the packet header is generated by dividing the metadata.

Also, the ESDU 100 generates a transmission header and outputs the disaster broadcasting service data multiplexed or muxed together with the packet header to the disaster broadcast transmission data unit (ETDU) 200. At this time, the disaster broadcasting service data is output through a predetermined communication protocol. This communication protocol is an Emergency Data Interface (EDI).

The Emergency Transmission Data Unit (ETDU) 200 channel-codes and interleaves the disaster broadcast service data received from the ESDU 100 according to the transmission standard, And performs frame synchronization. After signal generation and masking, EMC (Electro Magnetic Compatibility) power control is performed.

Referring to FIG. 4, the EDI frame includes a 2-byte STX field, a Type field, a Data field, a CRC field, and an ETX field.

Here, the STX field is a synchronization field indicating the start of the EDI frame, and its value is set to 0xA55A.

The Type field is a field indicating the EDI frame type. EDI frames are classified into two types as transmission frames (transmission header + transmission packet) and transmission status frame, as shown in Table 1.

Type EDI frame value (Value) 0x0 One transmission frame (a bundle of one transmission header (4 bytes) and one transmission packet (187 bytes) 0x1 Transmission status frame 0x02 to 0xFF Future use

As can be seen in Table 1, the structure of the Data field varies depending on the value of the Type field. The meaning of the Data field value is as follows.

As shown in FIG. 4A, when the Type field value is a transmission frame (Type = 0x0), SEQ ID (1 byte) means a unique number of a multiplexed transmission frame. SEQ_SIZE (4 bytes) means the total number of multiplexed transmission frames. SEQ_NO (4 bytes) means the sequence number (starting from 0) of the multiplexed transmission frame. Value (191 bytes) means one transmission frame (a bundle of transmission header and transmission packet), and includes a transmission header (4 bytes) and a transmission packet (187 bytes). In this case, the transmission header (4 bytes) indicates whether or not a disaster (1 bit), a protection level (3 bits), a transmission packet SF (Spreading Factor) (2 bits), Rfu ), Rfu (8 bits), and transmission head CRC (8 bits).

As shown in FIG. 4B, when the Type field value is a transmission status frame (Type = 0x1), SEQ ID (1 byte) indicates a unique number of a multiplexed transmission frame. SEQ_SIZE (4 bytes) means the total number of multiplexed transmission frames. SEQ_NO (4 bytes) is fixed to a value of 0. Value (1 byte) means transmission status frame, and is shown in Table 2 below.

Value Transmission status Meaning 0x0 STOP 0x1 to 0xFF Not defined

On the other hand, the CRC field is an error check field of the EDI frame, and the CRC error check target field is a Type field and a Data field.

The ETX field indicates a synchronization field indicating the end of the EDI frame, and its value is set to 0x1AA1.
