Video conference systems implementing orchestration models

摘要

A method for generating an output video stream in a video conference comprising receiving a plurality of input video streams of the video conference,Receiving a series of observation events (52, 53, 54), the observation corresponding to actions made by participants of the video conference, Providing a plurality of orchestration models each comprising a set of display states,;Determining, for each of the orchestration models a probability of the series of observation events received,;Selecting an orchestration model corresponding to the highest probability, Using the selected orchestration model to perform the steps of:o Selecting a display state (51, 40, 41, 42) as a candidate display state,o Determining a conditional probability of the candidate display state for the received series of observation eventso Determining the candidate display state providing the highest conditional probability as an updated display state,o Generating a video stream comprising the current display state and the updated display state.
