Automatic video layouts for multi-stream multi-site presence conferencing system

摘要

A videoconference multipoint control unit (MCU) automatically generates display layouts for videoconference endpoints. Display layouts are generated based on attributes associated with video streams received from the endpoints and display configuration information of the endpoints. An endpoint can include one or more attributes in each outgoing stream. Attributes can be assigned based on video streams' role, content, camera source, etc. Display layouts can be regenerated if one or more attributes change. A mixer can generate video streams to be displayed at the endpoints based on the display layout.

1. A method for generating display content for a first endpoint communicating over a network with at least one other endpoint comprising:
generating a display layout for the first endpoint, wherein generating the display layout further comprises:
generating a plurality of cells, andassigning video streams received from the at least one other endpoint to the plurality of cells based at least in part on one or more positional or role-based attributes associated with each of the video streams; and mixing received video streams to generate one or more video streams for one or more cells, wherein mixing further comprises combining video streams; and wherein the display layout preserves a spatial relationship between at least two of the video streams received from the at least one other endpoint, and wherein the one or more positional attributes identify a relative location of a camera generating the received video stream.
