Abstract

The invention discloses a method for awakening an emergency broadcast by DRM, an IPTV 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, the emergency message comprises an emergency instruction and emergency information, and the emergency information is emergency broadcast content; an IPTV receiving module obtains an IPTV program from an IPTV broadcast television signal; a first control module receives the emergency message, executes the emergency instruction, and awakens the IPTV set top box in advance for a necessary time period; and the first control module converts the emergency broadcast content into a media type, 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 IPTV 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 waking up emergency broadcasting by DRM, an IPTV set-top box and a system. Background technique [0002] The interactive Internet TV IPTV set-top box receives, demodulates, demultiplexes and decodes the IPTV 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 IPTV set-top boxes. When the IPTV 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 emergency messages into IPTV radio and television signals, and the IPTV set-top box receives and separates the emergency messages. The disadvantage is that the IPTV r...
