Embodiment

[0041] figure 1 It shows a structural flowchart of the emergency broadcast overlay scene switching method in this embodiment.

[0042] Such as figure 1 As shown, this embodiment is a method for switching emergency broadcast overlay scenes. The method is applied to an emergency broadcast overlay scene switching system, wherein the system includes an emergency decoding module, and the emergency decoding module is connected with the current output source of the terminal in the system. The decoding modules are independent of each other, that is, there are at least two decoding modules in the system, and one of the decoding modules is used as an emergency decoding module. The method specifically includes:

[0043] 101. Monitor and receive emergency data sent by the superior platform.

[0044] According to the output of the upper-level platform, the lower-level equipment receives the emergency data sent by the upper-level platform through the receiving module when an emergency si...

Abstract

The invention relates to the technical field of emergency broadcast, in particular to an emergency broadcast pad broadcast scene switching method and system. The invention is applied to an emergency broadcast underlay scene switching system, and the system comprises an emergency decoding module; the method comprises the following steps: monitoring and receiving emergency data sent by a superior platform; analyzing the emergency data according to an emergency protocol to obtain emergency information required by underlay; decoding the emergency information through an emergency decoding module toobtain an emergency information level and emergency audio and video data; and according to the emergency information level, realizing combined coding of the emergency audio and video data and the current output audio and video data, and realizing pad broadcast output of the emergency broadcast on the terminal. The invention is simple to use, does not need to formulate a pad broadcast program in advance, can achieve audio and video data processing through analysis, is flexible in switching of the pad broadcast scene, can flexibly switch the pad broadcast scene according to a superior instruction, namely an emergency information level, does not affect program playing of a receiver, and greatly improves the receiving experience of the receiver.

Description

technical field [0001] The present invention relates to the technical field of emergency broadcasting, in particular to a method and system for switching emergency broadcasting overlay scenes. Background technique [0002] Emergency broadcasting means that when major natural disasters, emergencies, public health and social security and other sudden public crises occur, emergency broadcasting can provide a fast and efficient information transmission channel, and the disaster news or disasters that may be caused The hazards are delivered to the hands of the people, so that the people know what happened at the first time, how to evacuate, avoid danger, and minimize the loss of life and property. [0003] The advance broadcast of the current emergency broadcast usually needs to customize the advance broadcast content, and then send it to the terminal for advance broadcast, and the advance broadcast usually has a single method, which needs to completely take over the playback of ...
