Embodiment Construction

[0043] In order to provide an implementation plan for reducing the delay difference between audio data and image data transmission, the embodiment of the present invention provides a data transmission method and transmission device for live video broadcasting. The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings .

[0044] figure 1 The flow chart of the data transmission method for live video broadcasting provided by the embodiment of the present invention includes:

[0045] 101: The first client establishes a UDP (User Datagram Protocol, User Datagram Protocol) connection with the second client.

[0046] 102: The first client collects audio data and image data of the first anchor.

[0047] In the scenario where two anchors, the first anchor and the second anchor, perform interactive live broadcast, the client where the first anchor is located is the first client, and the client where the second anchor is lo...

Abstract

The embodiment of the invention provides a data transmission method and transmission apparatus for live video. The method comprises the following steps: establishing a UDP connection with a second client by a first client; collecting audio data and image data of a first anchor; and sending the audio data and the image data of the first anchor to the second client through the UDP connection by using a WebRTC protocol. The first client sends the audio data and the image data of the first anchor to the second client through the UDP connection by using the WebRTC protocol, the UDP connection is oriented to non-connection, the transmission rate is high, the transmission delay difference of the audio data and the image data is reduced, and the interactivity between two anchors is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data transmission method and transmission device for live video broadcasting. Background technique [0002] Internet video live broadcast technology can realize the transmission of the anchor's live performance to the audience of the anchor. During specific implementation, the microphone is used to collect the audio data of the anchor, the camera is used to collect the image data of the anchor, and the audio data and video data are transmitted to the audience through the live video server for display. [0003] However, it is rather monotonous to just watch a live performance of an anchor. The live interaction between two anchors to the audience becomes a new live video hotspot. The anchor A terminal transmits the audio data and image data of the anchor A to the live video server, and requests the audio data and image data of the anchor B from the live video s...
