Embodiment Construction

[0082] 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.

[0083] Example Figure 1-3 As shown, the method, DTMB set-top box and system for waking up emergency broadcast by DRM, wherein,

[0084] In one aspect of this embodiment, the method for waking up an emergency broadcast by DRM includes the following steps:

[0085] (1) When the DTMB set-top box 400 is turned off or in standby or playing programs, the DRM receiving module 1 receives the DRM broadcast signal, demodulates and decodes to obtain DRM data, and then the DRM decryption and analysis module 2 decrypts and analyzes the DRM data to obtain emergency messages;

[0086] Emergency messages, including emergency instructions and emergency information;

[0087] Emergency information is the content of emergenc...

Abstract

The invention discloses a method, DTMB set top box and system for awakening an emergency broadcast by a 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 DTMB receiving module obtains a DTMB program from the DTMB broadcast television signal; a first control module receives the emergency message, executes an emergency instruction, and awakens the DTMB 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 DTMB 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 DTMB set-top box and a system. Background technique [0002] The terrestrial digital TV DTMB set-top box receives, demodulates, demultiplexes and decodes the DTMB broadcast TV signal to obtain broadcast TV program data, and outputs it to the TV for playback. When a natural disaster or social public event occurs, the emergency broadcast management platform sends an emergency message to the DTMB set-top box. When the DTMB 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 DTMB broadcast TV signal, and the DTMB set-top box receives and separates the emergency message. Demodulation and decoding require high-frequency com...
