Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] Such as figure 1 As shown, the embodiment of the present invention relates to an audio transmission method, including:

[0046] Step S101, acquiring the sending status signal of each channel of audio and the sending status signal of each channel of video;

[0047] In this step, the audio sending state signal includes: the audio is in a sending state or not in a sending state.

[0048] The audio sending status signal can be obtained directly, or the audio sending status signal can be obtained through the audio detector; if there are multiple audio channels, the sending status signal of each audio channel needs to be obtained separately.

[0049] The video sending status signal include...

Abstract

The invention discloses an audio sending method and apparatus. The method comprises the following steps: obtaining a sending state signal of each channel of audio and a sending state signal of each channel of video; establishing a mapping relation between each channel of video and audio simultaneously sent by the channel of video; and when the video is sent, controlling the sending state of the audio and sending one channel or more channels of video that correspond to the above channel of the video according to the mapping relation. Through the mapping relation established between video sending and audio sending, when video is sent, one channel or more channels of audio corresponding to the video can be sent. In this way, audio data can be sent according to far-end demands, and the conference effect is enhanced. Thus, the user experience is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of video conferencing, in particular to an audio transmission method and device. Background technique [0002] Video conferencing is a multimedia communication method that uses video technology and equipment to hold real-time, two-way, interactive video conferences in remote remote places through modern communication networks. [0003] Conference TV often has multiple channels of audio and video input and output and multiple channels of audio and video codec. Multiple channels of audio are often sent and played together with the video after mixing. Sometimes the video channel does not need all the audio to play in the conference, only one of them is needed. sound or want to select certain channels of sound in order to achieve a better conference effect. The existing technology has the following scenarios: [0004] Example 1: A terminal has two audio inputs and two video outputs. After the conferen...
