Example Embodiment

[0024] Example 1

[0025] This embodiment provides a method for audio mixing in a video conference, which can be used for audio mixing under cloud computing conditions. It should be noted that the following audio mixing resources (including main mixing resources) in the embodiments of the present invention (Master-MP) and auxiliary mixing resources (Slave-MP)) can be hardware mixers, or software-implemented mixing resources, which can be used to mix and encode audio. Among them, the main mixing resource can be pre-designated from the pre-created mixing resources. After the main mixing resource is designated, the other mixing resources are collectively called auxiliary mixing resources.

[0026] Such as figure 1 As shown, the method includes:

[0027] Step S101: The main audio mixing resource receives the audio code stream sent by the auxiliary audio mixing resource, where there are one or more auxiliary audio mixing resources, and each auxiliary audio mixing resource is used to mix ...

Example Embodiment

[0061] Example 2

[0062] This embodiment provides a video conference audio mixing device, which can be used to perform the video conference audio mixing method of Embodiment 1 of the present invention, such as image 3 As shown, the device includes: a receiving unit 10, a judgment unit 20, a query unit 30, and a distribution unit 40.

[0063] The receiving unit 10 is arranged on the main audio mixing resource, and is used to receive the audio code stream sent by the auxiliary audio mixing resource. There are one or more auxiliary audio mixing resources, and each auxiliary audio mixing resource is used for the communication of at least two venues. Audio stream is mixed.

[0064] The main mixing resource may have its responsible conference venues and receive the audio code streams of these conference venues, or it may only receive the audio code streams sent by the auxiliary mixing resources.

[0065] The judging unit 20 is used to judge whether the main sound mixing resource is fully ...

Abstract

The invention relates to the field of audio mixing, and specifically relates to a video conference audio mixing method and device. The method comprises the steps that a master audio mixing resource receives audio code streams sent by slave audio mixing resources, wherein there is one or more slave audio mixing resources, and each slave audio mixing resource is used for carrying out audio mixing on audio code streams of at least two conference places; judging whether the master audio mixing resource is fully loaded or not; searching an idle slave audio mixing resource when it is judged that the master audio mixing resource is fully loaded; distributing partial audio code streams received by the master audio mixing resource to the idle slave audio mixing resource when the idle slave audio mixing resource is searched; and after audio mixing is carried out on the partial audio code streams by the idle slave audio mixing resource, sending the processed audio code streams to the master audio mixing resource. Through adoption of the method and the device, the problem that in the prior art, the number of the conference places capable of accessing audio mixing is liable to be limited by the audio mixing processing capability is solved, and the limitlessly extendable intelligent audio mixing of the conference places with extra large number of squares can be realized.

Description

technical field [0001] The invention relates to the field of audio mixing, in particular to a video conference audio mixing method and device. Background technique [0002] Intelligent audio mixing is a core technology used in multi-party video conferencing. Its advantage is that, without human-computer interaction, the MCU platform can independently select the most suitable participants, mix their voices and send them to all participants, and meet several basic requirements at the same time: 1. Users do not need to apply or intervention; second, the conversation is clear and smooth, without interruption or noise; third, any site can interrupt at any time; fourth, the user will not hear his own voice. [0003] Under cloud computing conditions, unlike traditional multi-level conferences, all sound and image streams will be sent to the MCU platform in the data center for processing and exchange. With the enrichment of video application scenarios, there are more and more vide...
