Embodiment Construction

[0020] The media stream transmission method provided by the present invention performs media capability negotiation between the calling end and the called end and establishes multiple media channels. When performing media stream communication, the media stream is first transmitted on the first media channel. When the media stream transmission of the first media channel is abnormal, the current media stream is switched to other media channels for transmission to ensure the media communication quality of both communication parties.

[0021] Embodiment 1 of the present invention provides a media stream transmission method, the implementation process is as follows figure 1 shown, including:

[0022] Step S101: Carry out media capability negotiation between the calling end and the called end, and establish at least two media channels.

[0023] Specifically, at the beginning of the media communication, the calling end initiates a link establishment request message, and the request ...

Abstract

The invention discloses a media stream transmission method and device and aims to solve the problem that the audio and video quality is reduced in the media stream transmission process due to reasons such as packet loss, jitter and / or link breaking in the prior art. The method comprises the following steps: according to a link-building request message sent by a calling terminal and a response message from a called terminal for the link-building request message, conducting media ability negotiation between the calling terminal and the called terminal, and building at least two media channels; according to the negotiated media ability, conducting a media stream transmission through a first media channel; when detecting that an exception occurs in the media stream transmission of the first media channel, selecting the rest one media channel in the at least two media channels as a second media channel, and switching a media stream from the first media channel to the second media channel to be transmitted. The audio and video quality of two communication parties can be ensured through the method and the device.

Description

technical field [0001] The invention relates to the technical field of media transmission, in particular to a method and device for redundant transmission of media streams. Background technique [0002] During media transmission, when two terminals need to interact with media streams, they need to negotiate media capabilities first. Media capabilities generally include: the terminal’s media channel IP address and port number, audio and video media, encoding type, and related parameters. The establishment of the media channel is completed through media capability negotiation, and then on the established media channel, the encoding of the audio and video media data is completed according to the negotiated audio and video media data encoding type and related parameters, and the encoded media data is packaged and sent to Peer. [0003] In the prior art, the media channel between the two communication parties is generally established through signaling negotiation. When the media...
