The GCommS (Group Communication Support for Distributed Communication Systems) project at Lancaster University is concerned with the support of group communication, especially for applications employing multimedia information. In this paper we introduce a study on requirements of multimedia group applications. Group support in existing systems is discussed. Examples to illustrate group application requirements are given and a set of characteristics to define these requirements is introduced. Based on the requirements study application level services are proposed.
