Abstract

The invention discloses a method for awakening emergency broadcast by a Beidou system, a DTMB set top box and a system, and the method comprises the steps that a Beidou short message receiving module and a Beidou short message decryption and analysis module obtain an emergency message from a Beidou short message broadcast signal, wherein the emergency message comprises an emergency instruction and emergency information, and the emergency information is an emergency broadcast content; the DTMB receiving module obtains a DTMB program from the DTMB broadcast television signal; the first control module receives the emergency message, executes an emergency instruction, and awakens the DTMB set top box in advance for a necessary time period; and the first control module converts the emergency broadcast content into media types, synthesizes and outputs the emergency broadcast content. According to the invention, the emergency message in the Beidou short message broadcast signal is detected and received in real time, and the DTMB set top box is awakened to carry out emergency broadcast.

Description

technical field [0001] The invention belongs to the technical field of emergency broadcasting, and in particular relates to a method for waking up emergency broadcasting by a Beidou system, a DTMB set-top box and a system. Background technique [0002] The terrestrial digital TV DTMB set-top box receives, demodulates, demultiplexes and decodes the DTMB broadcast TV signal to obtain broadcast TV program data, and outputs it to the TV for playback. When a natural disaster or social public event occurs, the emergency broadcast management platform sends an emergency message to the DTMB set-top box. When the DTMB set-top box is turned off, standby or playing programs, there is a problem of how to respond to emergency messages and play emergency broadcasts. [0003] The existing emergency broadcast system inserts the emergency message into the DTMB broadcast TV signal, and the DTMB set-top box receives and separates the emergency message. Demodulation and decoding require high-f...
