VIDEO CONFERENCE VIRTUAL ENDPOINTS

摘要

A method and a device providing one virtual endpoint dedicated to serve one particular real endpoint, and the virtual endpoint is typically installed on a server in the same local network as the associated real endpoint, where an MCU or a fraction of a distributed MCCJ also is installed. In the upstream direction, the virtual endpoint includes at least an upstream decoder, a scaling unit and an upstream encoder. In the downstream direction, the virtual endpoint includes at least a number of decoders, a composing unit and a downstream encoder.

1. A virtual endpoint adapted to be installed on a computer device associated with a video conference endpoint adapted to participate in a multi-party video conference, the video conference endpoint being adapted to encode and transmit an upstream media stream including at least video data in an upstream direction and to receive and decode a combined media stream in a downstream direction, the virtual endpoint comprising:
at least one upstream decoder adapted to decode the upstream encoded media stream received from the video conference endpoint into an upstream decoded media stream; a scaling device adapted to scale the upstream decoded media stream into a scaled upstream media stream; at least one upstream encoder adapted to encode the scaled upstream media stream into an encoded scaled upstream media stream; a first downstream decoder adapted to decode a downstream encoded media stream of a first resolution; at least one second downstream decoder adapted to decode at least one of a number of downstream encoded media streams of a second resolution; a media composer adapted to compose a combined downstream media stream of decoded media streams of the first and the second resolution; and at least one downstream encoder adapted to encode the combined downstream media stream.
