Embodiment Construction

[0144] The video conferencing system described below is capable of handling multiple sources to provide an enhanced immersive communication experience.

[0145] A video conferencing system is a telecommunications system capable of sharing audio and video communications between at least two locations. Live connections between people in separate locations increase social interaction. refer to figure 1 , one embodiment of a video conferencing system includes a video controller 1 and a plurality of terminals 2, which are referred to as organizers in this specification. These terminals are connected to the compiler through a communication network 10 . The communication network is adapted to transmit audio and video streams. In this context, the composer is able to manage the different live input video streams 11 sent by the terminal 2 . In order to create the output video, different blending methods exist. This disclosure proposes a dynamic blending method implemented by an or...

Abstract

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 events o 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.

Description

technical field [0001] The present invention relates to a method for generating immersive video from multiple sources of multiple people, particularly in a multi-party video conferencing system. Background technique [0002] As bandwidth capabilities in communication systems have increased, video communication systems have become increasingly popular in commercial and residential applications. Indeed, these systems avoid travel of team collaborators and increase flexibility in the case of geographically distributed team collaboration. [0003] Video communication systems use audio and video communication to bring people together from different locations. This could be as simple as a conversation between people in a private office, or involve several multipoint locations in a large room at multiple locations. The system is capable of managing point-to-point and multipoint communications. [0004] In known systems, the user uses a remote control to select the source (video ...
