Problems solved by technology

If the terminal equipment of the participant does not have or does not use the same audio codec, you cannot participate in the meeting
This not only limits the terminal equipment participating in the meeting, but also limits the application scope of the interconnection and intercommunication of the video conference server

Abstract

The invention provides a sound mixing processing method and a sound mixing processing system. The method comprises the following steps: receiving audio coding data and an audio coding type transmitted by a client; decoding the audio coding data by using an audio decoder corresponding to the audio coding type to acquire decoding data; comparing the sampling ratio of the decoding data with the sampling ratio of a preset server; if the sampling ratio of the decoding data is more than the sampling ratio of the preset server, downsampling the decoding data; if the sampling ratio of the decoding data is less than the sampling ratio of the preset server, upsampling the decoding data; and performing sound mixing operation on the decoding data under the condition that the sampling ratio of the decoding data is equal to the sampling ratio of the preset server and the downsampled decoding data / the upsampled decoding data to acquire sound mixing data. The invention allows terminal equipment of each party participating in a conference to use different audio coders / decoders, so that the application range of interconnection of video conference technology is greatly increased.

Description

technical field [0001] The invention relates to the field of video conferencing, in particular to a sound mixing processing method and a sound mixing processing system. Background technique [0002] At present, with the rapid development of network technology and video conferencing, the application technology of video and audio has been relatively mature. In practical applications, the complementary processing of audio is still at the most basic and core position, and the real-time requirements for audio are more stringent. Therefore, for multiple terminals in different locations in actual use, if multiple points For real-time audio interaction, if the network bandwidth allows, it is necessary to mix multiple channels of audio according to a certain strategy, and finally encode and transmit it to another terminal. [0003] However, whether it is a traditional video conferencing vendor or a network video conferencing vendor, their video conferencing requires that all parties...
