Problems solved by technology

[0002] Most of the current emergency broadcasting terminals are single source terminals, which often choose one of the sources from IP packets, subcarrier frequency modulation, limited digital TV, terrestrial digital TV, and direct broadcast satellite. Once the source fails, the manufacturer The terminal will not be able to receive emergency messages and issue broadcast notifications, completely losing the role of emergency terminals. From the perspective of display methods, most of the existing emergency broadcast terminals output audio content and cannot broadcast emergency video messages. The display methods are relatively backward. Unable to meet the needs of diverse scenarios
The current emergency broadcast terminals still lack good openness and scalability. In terms of openness, due to the singleness of information source selection, terminal manufacturers can only connect with customized management platforms and receive corresponding management instructions and business instructions. Once the platform fails, the terminal will be completely paralyzed and unavailable; in terms of scalability, most of the existing emergency broadcast terminals are developed for embedded systems, PCB boards are fixed, and software functions are fixed, so it is impossible to expand functions in a timely manner according to changes in requirements
Due to many shortcomings such as single source, limited and closed platform, poor scalability, and limited means of display, the emergency broadcast terminal has great limitations. Its application range is small, its coverage is narrow, and its emergency effect is poor. The timeliness, extensiveness and diversity of message broadcasting are required, so it is very necessary to invent and design a terminal system to change the defects in the existing technology

Abstract

The invention discloses an emergency broadcast convergence media gateway comprising a MCU unit, an audio and video decoding unit, a multi-information source access unit, a content output unit and an expanding unit, wherein the MCU unit is mainly connected with a system management platform, a third-party management platform and a third-party business platform; the audio and video decoding unit is mainly used for parsing received audio and video emergency message content; the multi-information source access unit receives an emergency broadcast message via coverage channels; the coverage channels comprise a network control channel, frequency modulation, a cable digital television, a ground digital television and a direct broadcast satellite; the content output unit is mainly used for outputting audios and videos; and the expanding unit mainly comprises an expanding device. The emergency broadcast convergence media gateway provided by the invention supports multiple information source access channels, is good in expansibility and openness and increased in full compatibility with audios and videos, embodies the terminal in a convergence media gateway manner, and can meet the usage requirements of different scenarios and different links.

Description

technical field [0001] The present invention relates to the field of emergency broadcast systems, in particular to an emergency broadcast integrated media gateway. Background technique [0002] Most of the current emergency broadcasting terminals are single source terminals, which often choose one of the sources from IP packets, subcarrier frequency modulation, limited digital TV, terrestrial digital TV, and direct broadcast satellite. Once the source fails, the manufacturer The terminal will not be able to receive emergency messages and issue broadcast notifications, completely losing the role of emergency terminals. From the perspective of display methods, most of the existing emergency broadcast terminals output audio content and cannot broadcast emergency video messages. The display methods are relatively backward. It cannot meet the needs of various scenarios. The current emergency broadcast terminals still lack good openness and scalability. In terms of openness, due ...
