Problems solved by technology

[0011] The problem with the existing IP broadcast technology is that there is a server performance bottleneck. All terminals in the network must be managed by a server, and the network capacity cannot be increased by expanding the number of servers (there is no connection between servers, and clients and applications connected to different servers The program cannot communicate, which is equivalent to an isolated network), when the number of terminals reaches a certain amount, the server cannot guarantee timely processing of communication with all terminals, and the sound playback is no longer smooth

Embodiment 1

[0061] Such as figure 1 , the whole system is divided into three layers, from top to bottom: application layer, network service layer, terminal layer. Among them, the network service layer is the core component of the distributed IP broadcast system, which shields the distribution details of the terminal equipment for the upper layer application.

[0062] System Layer Description

[0063] Application layer: The application layer is a variety of audio applications provided to users. These applications send audio streams from various sources to terminal devices, or receive audio streams collected and encoded from terminal devices on-site for processing. These applications include audio file playback, computer real-time acquisition and playback, alarm broadcast, internal intercom, scheduled broadcast, etc.;

[0064] Network service layer: The network service layer mainly includes two modules of session service (SessionSvr) and terminal service (TRMSvr). core components;

Abstract

The invention discloses a cloud broadcast system and a cloud broadcast method. An Internet protocol (IP) broadcast system is structurally formed by an application layer, a network service layer and a terminal layer, wherein the application layer comprises various audio application programs provided for users to use, and the application programs are used for transmitting audio streams from varioussources to broadcast terminals or receiving the audio streams acquired and coded in site by the broadcast terminals and processing the audio streams; the network service layer is used for managing all session objects and all the broadcast terminals in a network, and is provided with a session server and a terminal server; and the terminal layer consists of a plurality of broadcast terminals whichare connected with the terminal server to finally finish the digital-to-analogue conversion of sound signals. By the cloud broadcast system and the cloud broadcast method, bottlenecks in the performance of a single server are broken, and a large-scale IP broadcast network can be supported.

Description

technical field [0001] The invention relates to a cloud broadcasting system and method. Cloud broadcasting is IP network broadcasting that supports distributed expansion. Background technique [0002] The broadcasting system has a very wide range of applications in the production and life of the society. It can quickly and conveniently spread information in the form of sound, or it can be used as a broadcasting facility for background music or teaching programs. It can be used in stations, factories, mines, schools, communities, Hotels and other places have a very wide range of applications. [0003] The broadcasting system mainly solves the transmission problem of audio information. The initial broadcasting system was implemented with a constant-voltage power amplifier, and the sound signal was directly transmitted as an analog electrical signal, and multiple speakers could be connected to the audio line. The biggest problem with direct transmission of analog signals is ...
