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 a receiving parameter of an emergency broadcast DVB-C program; a DVB-C receiving module obtains a DVB-C program from the DVB-C broadcast television signal; a first control module receives an emergency message, executes an emergency instruction, awakens the DVB-C set top box in advance of 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 a receiving parameter of the DVB-C 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 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 in particular relates to a method for waking up emergency broadcasting by DRM, 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 DVB-C recei...
