Abstract

The invention relates to the technical field of communication, and particularly discloses a control method of an emergency broadcast audio broadcasting and forwarding platform system, and the emergency broadcast audio broadcasting and forwarding platform system comprises an emergency broadcast audio interface module which is used for receiving emergency broadcast audio; an emergency broadcast master control system, used for recovering the received emergency broadcast audio into PCM data and encoding the PCM data; an audio broadcasting interface module, used for broadcasting the coded PCM data;an audio forwarding interface module, used for forwarding the coded PCM data. The control method comprises the following steps: receiving an emergency broadcast audio; recovering the received emergency broadcast audio to PCM data; encoding the PCM data; broadcasting and forwarding the coded PCM data. The method not only can support standard emergency broadcast protocol processing, but also can becompatible with emergency broadcast audio processing of a traditional terminal, and equipment deployment is flexible and unlimited.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a control method of an emergency broadcast audio distribution and forwarding platform system. Background technique [0002] Emergency broadcasting system is the most effective media used to deal with various natural disasters and man-made disasters. At present, there are many terminal devices, and according to Chapter 10 of the emergency broadcast standard GD / J 086-2018, the terminal needs to provide support for the reception of emergency broadcast according to the new standard, but not all terminals have manufacturers that can update and upgrade. For those terminals that cannot be updated and upgraded, there are disadvantages of inconvenient use, and it is impossible to provide additional protection for the lives and properties of the people. [0003] For example, in the forwarding process of emergency broadcast audio, the general practice is to embed emergency broadcast...
