Abstract

The invention discloses a method for awakening an emergency broadcast by a Beidou system, a satellite television set top box and a system; 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, the emergency information being a receiving parameter of an emergency broadcast DVB-S program; the DVB-S receiving module is used for obtaining a DVB-S program from the DVB-S broadcast television signal; the first control module receives an emergency message, executes an emergency instruction, wakes up the DVB-S set top box in advance for a necessary time period, and transmits the emergency message to the main control module which receives program video and audio data; and the main control module sets receiving parameters of the DVB-S receiving module according to the emergency information, converts the media type of the emergency broadcast content, 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 DVB-S set top box is awakened to carry out emergency broadcast.

Description

Technical field[0001]The present invention belongs to the field of emergency broadcast technology, which involves a method, satellite TV set-top box and system that are awakened by the Beidou System.Background technique[0002]Satellite Digital TV DVB-S set-top box receives, demodulates, demodulates, decodes, declares, decomposes, decodes, to obtain broadcast TV program data, and outputs playback. When a natural disaster or social public event occurs, the emergency broadcast management platform sends emergency news to the DVB-S set-top box. The DVB-S set-top box is in shutting down, standby or playing shows how to respond to emergency news and play emergency broadcasts.[0003]The existing emergency broadcast system, inserts the emergency news into the DVB-S radio television signal, received by the DVB-S set-top box and separated emergency news, the disadvantage is the DVB-S receiving module and master module 7 * 24 for DVB-S set top boxes. Real-time operation, due to the DVB-S signal r...
