Abstract

The invention discloses a method for waking up emergency broadcast by a Beidou system, a cable television set top box and a system, and the method comprises the following steps: 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, and the emergency message comprises an emergency instruction and emergency information, wherein the emergency information is emergency broadcast content; the DVB-C receiving module obtains a DVB-C program from the DVB-C broadcast television signal; the first control module receives the emergency message, executes an emergency instruction, and awakens the DVB-C set top box in advance in a necessary time period; and the first control module converts the emergency broadcast content into a media type and synthesizes and outputs the media type. According to the invention, the emergency message in the Beidou short message broadcast signal is detected and received in real time, and the DVB-C 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 cable TV set-top box and a system. Background technique [0002] The cable digital TV DVB-C set-top box receives, demodulates, demultiplexes and decodes DVB-C radio and television signals, obtains radio and television program data, and outputs them to the TV for playback. When natural disasters or social public events occur, the emergency broadcast management platform sends emergency messages to DVB-C set-top boxes. When the DVB-C 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 DVB-C broadcast TV signal, and the DVB-C set-top box receives and separates the emergency message. The disadvantage is that the...
