Controllable emergency broadcast terminal capable of playing audios and videos in self-adaptive mode

Abstract

The invention provides a manageable and controllable emergency broadcast terminal capable of playing audios and videos in a self-adaptive mode. The manageable and controllable emergency broadcast terminal comprises a message receiving module, a main control module, a message playing module, a message playing and collecting module and a message playing and returning module. The main control module is connected with the message receiving module, the message playing module, the message playing and collecting module and the message playing and returning module; the master control module obtains the emergency broadcast message from the message receiving module, executes the emergency broadcast message, converts the broadcast content of the message into audio and video if the broadcast content of the message is not audio and video, transmits the audio and video of the broadcast content of the message to the message playing module, obtains message playing data from the message playing acquisition module, and sends the message playing data to the message receiving module. And transmitting the message playing data to a message playing return module. The emergency broadcast terminal for playing audios and videos can receive emergency broadcast messages with various media types of playing contents to play audios and videos, and can be managed and controlled.

Description

technical field [0001] The invention relates to the technical field of emergency broadcast terminals, in particular to a manageable and controllable emergency broadcast terminal that can adaptively play audio and video. Background technique [0002] The emergency broadcast terminal receives the emergency broadcast message sent by the emergency broadcast platform and broadcasts it. Here, the emergency broadcast message is referred to as message, the emergency broadcast terminal is referred to as terminal, and the emergency broadcast platform is referred to as platform. [0003] The existing emergency broadcast terminal is to output audio playback. The disadvantage of audio is that the audience tends to forget the front after listening, and it is not intuitive. It is inconvenient for the audience to fully understand the emergency situation. This requires the provision of emergency broadcast audio and video terminals for audio and video playback. The emergency broadcast messa...

Problems solved by technology

The disadvantage of audio is that the audience tends to forget the front after listening, and it is not intuitive. It is inconvenient for the audience to fully understand the emergency situation. This requires the provision of emergency broadcast audio and video terminals for audio and video playback

The content of the emergency broadcast messages issued by the emergency broadcast platform is generally text, or audio files, or video files, or audio and video files, or streaming audio, or streaming video, or streaming audio and video, while emergency broadcast audio Generally, video terminals can only process emergency broadcast messages whose content is audio and video, which limits the range of emergency broadcast audio and video terminals that can handle emergency broadcast messages. Emergency broadcast audio and video terminals that can play all emergency broadcast messages are required

Furthermore, in order to manage and control the emergency broadcast terminal, the emergency broadcast platform needs to obtain the broadcast status of the terminal, including the broadcast content, the live broadcast, the integrity of the broadcast content, and the integrity of the broadcast duration; the general terminal can only return the online status and broadcast State, unable to meet the requirements of terminal management and controllability, which requires the provision of management and controllable emergency broadcast terminal
