Embodiment Construction

[0035] The present invention provides a method and device for sending emergency broadcast services implemented on digital mobile multimedia broadcasting, which divides multiple emergency broadcast messages into segments, and packages them together with identification number information into segment data blocks, and then separates different emergency broadcast messages The segment data blocks of the data block are interleaved into a data block message in units of blocks, and then the different message segment data blocks in the data block message are encapsulated together with the identification number information into control table data, and finally, the control table data of multiple emergency broadcast messages are added to multiplex frame 0 of CMMB and send it out.

[0036] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] Fig. 5 shows the emergency broadcasting service ...
