Problems solved by technology

[0003] The traditional video conferencing system mainly has two technologies: H.323-based video conferencing system and SIP-based video conferencing system. Among them, the H.323-based video conferencing system is relatively mature at present, and most of them adopt the dedicated line-based MCU networking method. With good hardware environment support, its core audio and video processing technology is a proprietary technology. Its disadvantages are that the technology update is not timely, the price is expensive, and it cannot meet personalized customization. Moreover, its complex system structure is not conducive to popularization.
[0004] Traditional video conferencing systems are implemented based on hardware technology, and the cost is very high. A piece of equipment needs to invest millions of dollars at the most basic level, and each point requires an investment of 100,000 yuan. In addition, traditional video conferencing systems need to run on dedicated lines In order to ensure the quality of communication, a dedicated line costs tens of thousands of yuan per year

Embodiment 1

[0067] The example is basically as attached figure 1 Shown: Multi-terminal audio and video instant messaging system, including server and terminal;

[0068] The server is used to receive the connection establishment request sent by the terminal, and after responding to the connection establishment request, the communication protocol is upgraded from the HTTP protocol to the WebSocket protocol, and data can be directly exchanged between the server and the terminal, and the two-way channel will continue to maintain the connection. , the latest data of the server can be pushed to the terminal in real time, and the server communicates with the terminal in real time. Compared with the two real-time webpage technologies of Polling and Comet, WebSocket can reduce the delay and establish a continuous two-way channel for communication. It can effectively ensure the quality of communication. During communication, the header information exchanged between the server and the terminal is sm...

Embodiment 2

[0099] This embodiment is basically the same as the first embodiment, the difference is:

[0100] The server also includes an identity label management module, a rights management module, a detection module, a judgment module, a storage module, a content label management module, an identification module, a subtitle generation module and a guidance document generation module;

[0101] The identity label management module is used to add identity labels to users; wherein the identity labels include: commanders, operation and maintenance personnel and guidance experts, and one user can add multiple identity labels;

[0102] Permission management module, used to set user permission value;

[0103] The detection module is used to detect the identity tag of the speaking user in the current room;

[0104] a judgment module for judging whether the identity tag information of the speaking user is a guidance expert, and if so, start the recording module of the speaking user's terminal a...

Embodiment 3

[0120] The example is basically as attached figure 2 Shown: Multi-terminal audio and video instant messaging method, including the following:

[0121] S1. The terminal sends a connection establishment request;

[0122] S2. The server receives the connection establishment request, and after responding to the connection establishment request, upgrades the communication protocol from the HTTP protocol to the WebSocket protocol, the server communicates with the terminal in real time, and the server sends the network information, local audio and video codec protocol and resolution information to the terminal. , establish an end-to-end connection between terminals, and aggregate multiple terminals for real-time communication, and create a room for unified management; establishing an end-to-end connection between terminals, including:

[0123] Find the public network IP of the terminal, so that the audio and video data can be directly transmitted between the terminals through the p...

Abstract

The invention relates to the technical field of communication, in particular to a multi-terminal audio and video instant messaging method and system, and the system comprises a server and terminals. The server is used for receiving the connection establishment request sent by the terminal, after the connection establishment request is responded, a communication protocol is upgraded to a WebSocket protocol from an HTTP protocol, and the server communicates with the terminal in real time; the server is also used for gathering a plurality of terminals for real-time communication, creating a room for unified management, and sending a socket Id of a new terminal to other terminals in the room when the new terminal is added into the room; the terminal is used for sending a connection establishment request to the server; the server is also used for receiving socket Id of other terminals and sending an offer to the other terminals to request to establish connection; receiving the offer sent by the other terminal, and replying to the answer to establish connection with the other terminal; the terminals and the server and the terminals are interacted through signaling. According to the scheme, the communication quality can be effectively ensured, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for instant communication of multi-terminal audio and video. Background technique [0002] Video conference system is a comprehensive application of various technologies such as network, communication and multimedia. With the increasingly strong demand for real-time information, video conferencing has attracted more and more attention due to its intuitive, real, cross-regional, and low-cost communication characteristics, and is widely used in various fields of various organizational activities, such as Distance education, distance negotiation, telemedicine, remote diagnosis, remote scheduling, etc. [0003] There are two main types of traditional video conference systems: H.323-based video conference systems and SIP-based video conference systems. Among them, H.323-based video conference systems are relatively mature, and most of them use a dedicated li...
