Abstract

The present invention relates to a method, system, client device, conference server device and computer program product of controlling media composition in a multi-party conversation involving a central control point (50). At a participant (10) of said multi-party conversation, a scope information (SoM) which specifies members of said multi-party conversation is selected and added to a session modifying request. The session modifying request is transmitted to the central control point (50) which initiates a media modification at the specified members in response to the scope information (SoM). Thereby, a client can control whether media modification is applied to the whole conference, selected participants or only between the client itself and the conference server.

Claims

selecting, by a participant at a client device of the participant currently in a multi-party conversation session, scope information that specifies one or more members currently in the multi-party conversation session for whom a modification of a media type received by the one or more participants from a central point is to be applied;

generating, by the client device, a session modifying request based on the selected scope information; and

determining, by the client device, to transmit from the client device, said session modifying request to a central control point to apply the media type modification specified by said selected scope.

2. A method according to claim 1, wherein said selected scope information is a header parameter or an attribute of said session modifying request.
