Problems solved by technology

[0003] However, due to the transmission uncertainty brought about by the fluctuation of network bandwidth; multi-channel, a large number of audio and video signal packets are sent to each user terminal through the server in real time, and the network data to be received by each user terminal will follow the chat room. Rapid growth doubled with the increase in the number of users
In this way, during the entire video communication process, the network bandwidth i

Embodiment

[0021] figure 1 It is a signaling flowchart for inviting other users to join after successfully creating a video chat room.

[0022] like figure 1 shown, including the following steps:

[0023] Step 1. User A (the user who has the right to apply for chat room resources) applies for a chat room resource from the HTTP conference server through the XML protocol, and creates a video conference;

[0024] Step 2, the conference server sends feedback information to user A after completing the creation of the chat room, and the feedback information includes information such as the IP address of the video conference server, the chat room number, the chat room password, and the chat room type;

[0025] Steps 3-6, user A invites user B and user C to join the chat room through the Web; the conference server achieves the goal by setting the permission for users B and C to enter the chat room;

[0026] There are two situations for users to enter the chat room. One is that the user who cr...

Abstract

The invention discloses a method for realizing a multiuser network video chat system for intensifying simplex video quality, wherein the method is implemented through the following procedures: after a user enters a chat room, an audio terminal can receive the audio information of all users in the chat room in real time; the video terminal of the user only can be used for receiving and watching a simplex video user picture all the time; and the video terminal can switch the pictures for a certain appointed user in the current chat room at any time. According to the method, the video signal quality is obviously enhanced, network resources are saved, and the complex operation of the system is simplified.

Description

technical field [0001] The invention relates to the technical field of video communication, in particular to a realization method and mode of a brand-new video chat system that strengthens single-channel high-quality video in multi-person video chat through the Internet. Background technique [0002] Among existing instant messaging applications, video communication is a very extensive application. In the prior art, point-to-point communication between individuals also has multi-person video communication; in the case of multi-person video communication, many implementations currently on the market are to display the current chat in the same window Video image information of everyone in the room. [0003] However, due to the transmission uncertainty brought about by the fluctuation of network bandwidth; multi-channel, a large number of audio and video signal packets are sent to each user terminal through the server in real time, and the network data to be received by each u...
