Abstract
The present invention relates to a method, terminal device and conference server device for providing a multiparty conference in a data network, wherein an individual presentation layout for participants in a composite video image is selected by a participant and transmitted to the conference serving function. Based on the layout information, a composite signal is generated so that the requesting participant has knowledge of the locations of individual participants' information streams, e.g. video stream, within the composite signal. Thereby, the participant can allocate specific information, such as names, titles or functions, to audio or video streams of the multiparty conference.
