Embodiment Construction

[0046] The present invention provides an audio and video communication method, device and system. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] see figure 2 , figure 2 It is a flowchart of a preferred embodiment of an audio and video communication method of the present invention, as shown in the figure, which includes steps:

[0048]S101. The first user registers through the XMPP server and obtains the identity information of the second user. Specifically, the data sent to the XMPP server can be encapsulated through the XMPP protocol [Extensible Communication and Presentation Protocol: The Extensible Messaging and Presence Protocol];

[0049] S102. The first user sends an audio and video...

Abstract

The invention discloses an audio and video communication method, device and system. The method comprises the following steps that a first user registers via an XMPP (XML-based Messaging and Presence Protocol) server and acquires the identity information of a second user; the first user sends an audio and video communication request to the second user according to the identity information of the second user, receives the address information of the second user transmitted by an STUN (Simple Traversal of UDP over NATs) server and acquired according to the request information of the first user, and establishes a communication link with the second user according to the received address information of the second user; the first user processes extracted audio and video data via WEBRTC (Web Real-Time Communication), encapsulates in the form of an XMPP protocol to obtain audio and video data to be transmitted, and transmits the audio and video data to be transmitted on the communication link established between the first user and the second user to realize audio and video communication between two ends. By adopting the method, an end-to-end high quality communication effect can be realized among equipment without a server.

Description

technical field [0001] The invention relates to the technical field of audio and video communication, in particular to an audio and video communication method, device and system between smart devices. Background technique [0002] In the prior art, traditional TV audio and video communications must send messages through a central agent and redirection service, such as figure 1 As shown, the client network TV needs to send messages through the video call proxy and redirection server, which greatly increases the amount of data carried by the server and the amount of processing. On the other hand, for accurate data transmission, traditional TV uses Complicated audio and video encoding and decoding mode, that is, after the network data passes through the network decoding module, it needs to be processed by the audio decoding module, the video decoding module, the audio encoding module and the video encoding module. The processing process is complicated, which makes the data tran...
