Abstract

This invention discloses a video and audio processing method, multi-point control unit and video conference system, especially a video processing method, audio processing method, video processing device, audio processing device, multi-point control unit and a video conference system. The video processing method includes: obtaining a N-path video stream sent by a first conference terminal; determining a second conference terminal interactive with the first conference terminal, the second conference terminal supports a L-path video stream different from the N; taking the N-path video information in the N-path video stream into a L-path video stream; transmitting the L-path video stream to the second conference terminal. Supporting the interaction between different media stream paths can be realized through the embedment of this invention, and remotely displaying the combination among the meeting place, dual-stream meeting place and signal stream meeting place can be realized too. This invention is in favor of reducing the construction cost of the whole network.

Description

technical field [0001] The invention relates to audio and video technology, in particular to a video processing method, an audio processing method, a video processing device, an audio processing device, a multipoint control unit and a video conference system. Background technique [0002] In the original video conferencing system, each meeting site can only send one video image, which is generally a conference room scene captured by a camera, providing participants with a face-to-face effect. With the continuous advancement of video conferencing technology, a dual-stream standard has emerged, allowing participants to send two-way video images, the mainstream sending the conference room scene captured by the camera, and the auxiliary streaming can send the film image on the laptop, which improves the communication between the participants. data sharing. Further, a telepresence system has appeared, which can transmit multiple camera images at the same time, and multiple camer...
