Abstract

The invention discloses a method, cable television set top box and system for awakening emergency broadcast by DRM, and the method comprises the following steps: a DRM receiving module and a DRM decryption analysis module obtain an emergency message from a DRM broadcast signal, wherein the emergency message comprises an emergency instruction and emergency information, and the emergency information is emergency broadcast content; a DVB-C receiving module obtains a DVB-C program from the DVB-C broadcast television signal; a first control module receives the emergency message, executes an emergency instruction, and awakens the DVB-C set top box in advance of a necessary time period; and the first control module converts the media type of the emergency broadcast content, synthesizes and outputs the emergency broadcast content. According to the invention, the emergency message in the DRM 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 particularly relates to a method, a cable TV set-top box and a system for waking up emergency broadcasting by DRM. Background technique [0002] The cable digital TV DVB-C set-top box receives, demodulates, demultiplexes, and decodes the DVB-C radio and television signal, obtains the radio and television program data, and outputs it to the TV for playback. In the event of natural disasters or social public events, the emergency broadcast management platform sends emergency messages to the DVB-C set-top box. When a DVB-C set-top box is turned off, on standby or playing a program, there is a problem of how to respond to emergency messages and play emergency broadcasts. [0003] In the existing emergency broadcast system, the emergency message is inserted into the DVB-C radio and television signal, and the DVB-C set-top box receives and separates the emergency message. The disadv...
