Method and apparatus for improved network optimization for providing video from a plurality of sources to a plurality of clients

Abstract

A method for improving quality of experience in a communication between a first plurality of video sources (Cam, cam, cam) to a second plurality of video clients (C, C) via a video composing module (VSE) in between said first plurality of video sources and said second plurality of clients, and triggered by a dispatching unit (D) controlling which clients and video sources are participating in said communication, and which respective composed videos (VcompC, VcompC) are to be provided from said video composing module (VSE) to respective clients (C, C) of said second plurality, comprises the steps of :—receiving from said dispatching unit (D) client related parameters (CP, CP) indicating display and layout configuration of said respective composed video (VcompC, VcompC) to be provided to said respective client (C, C),—identifying a subset of video sources from said first plurality for being coupled to an intermediate video composing module (VSRR)—determining an optimized video feed configuration for the communication of an intermediate composed video (Vcompr) provided by and between said intermediate video composing module (VSRR) to said video composing module (VSE) based on said client related parameters and on network restriction parameters (NC(t)),—adapting the respective video communication session between the intermediate video composing module (VSRR) and the video composing module (VSE) based on the provision of said optimized video feed configuration as a control signal to said intermediate video composing module (VSRR).
