Telepresence method, terminal and system

摘要

The disclosure discloses a telepresence method, a telepresence terminal and a telepresence system. The system includes a telepresence terminal, multiple audio inputting devices and multiple audio outputting devices and/or multiple video inputting devices and multiple video outputting devices and a remote endpoint, wherein the telepresence terminal has multiple audio and video inputting and outputting interfaces for connecting the multiple audio inputting devices and the multiple audio outputting devices and/or the multiple video inputting devices and the multiple video outputting devices, and is configured to: establish a session, exchange input/output location information of multiple audio streams and/or video streams, perform media capability negotiation, and establish media logical channels with the remote endpoint; encode streams input by the multiple audio inputting devices and/or the multiple video inputting devices, and send the encoded streams to the remote endpoint according to input/output locations of the streams based on the established media logical channels; receive and decode multiple audio streams and/or video streams from the remote endpoint, and forward the decoded streams respectively to audio outputting devices and/or video outputting devices at local locations corresponding to input/output locations of the multiple audio streams and/or video streams received, so that the decoded streams are played by the audio outputting devices and/or the video outputting devices at the local locations. With the disclosure, problems of complicated deployment of an existing telepresence system, intercommunication and stream synchronization within the system are solved.
