Collaboration system for a virtual session with multiple types of media streams

Abstract

A method for controlling data streams of a virtual session with several participants who access at least access one application in the virtual session can include use of a selected media processing and a signaling mode in a centralized process for each participant according to the individual requirements of the participant. The process can be controlled by a server. The selection of the media processing and/or signaling mode can be made on the basis of an evaluation of the terminal of the respective participant and the network bandwidth available to the respective participant. An evaluation scheme with a plurality of evaluation criteria can be provided for the evaluation, and possible media processing and/or signaling modes are ascertained for the respective participant.
