A data communication system (10) includes a central server (20) coupled via a communication network (60) to plural client devices (30). The server and clients exchange data. The system allocates the data into a primary type and at least a secondary type. The primary data is communicated substantially immediately within the system, and at least the secondary data is communicated after receipt of acknowledgements (ACK) corresponding to secondary data already sent. In an example the primary data is audio and the secondary data is video, so that audio data is sent without delays occurring in the audio stream. The server hosts one or more services, for example a virtual room, a multipoint server and/or a multiplayer server providing at least one of video conferencing, video broadcasting, teleconferencing, multiuser gaming and video-Âon-demand to client devices. At least one of the client devices may be wireless-enabled. |
