Embodiment Construction

[0072] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0073] Example Figure 1-3 As shown, the method, satellite TV set-top box and system relying on DRM to respond to emergency broadcasting, wherein,

[0074] One aspect of this embodiment provides a method for responding to emergency broadcasts by means of DRM, including the following steps:

[0075] (1) When the DVB-S set-top box 400 is turned off or in standby or playing a program, the DRM receiving module 1 receives the DRM broadcast signal, demodulates and decodes the DRM data, and then the DRM decryption and analysis module 2 decrypts and analyzes the DRM data to obtain emergency information;

[0076] Emergency messages, including emergency instructions and emergency information;

Abstract

The invention discloses a method for responding to an emergency broadcast by DRM, a satellite television set top box and a system. The method comprises the following steps that: a DRM receiving module and a DRM decryption analysis module obtain an emergency message from a DRM broadcast signal, with the emergency message comprising an emergency instruction and emergency information, and the emergency information being a receiving parameter of an emergency broadcast DVB-S program; a DVB-S receiving module acquires a DVB-S program from a DVB-S broadcast television signal; a main control module for receiving the video and audio data of the DVB-S program receives the emergency message, executes the emergency instruction and awakens the DVB-S set top box in a necessary time period in advance; and the main control module sets receiving parameters of the DVB-S receiving module according to the emergency information, converts the emergency broadcast content into a media type 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-S set top box is awakened to carry out the emergency broadcast.

Description

technical field [0001] The invention belongs to the technical field of emergency broadcasting, and in particular relates to a method for responding to emergency broadcasting by means of DRM, a satellite TV set-top box and a system. Background technique [0002] The satellite digital TV DVB-S set-top box receives, demodulates, demultiplexes and decodes DVB-S radio and television signals to obtain 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-S set-top boxes. When the DVB-S 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-S broadcast TV signal, and the DVB-S set-top box receives and separates the emergency message. The disadvantage i...
