Summary: | A content based messaging audio and video conferencing system (100) provides a messaging infrastructure for multimedia and collaborative applications. The audio/video conferencing system (100) may be implemented using a publish/subscribe infrastructure, such as a content-based messaging (CBM) infrastructure and system (120). Conference participants (110) may exchange audio and/or video data streams (130, 135) using the CBM system (120). A list of contacts (422) displays the current status of users (420). For example, the status of a user may be offline, online, and in a conference. The conference system (100) uses the publish/subscribe infrastructure (120) to provide instant state changes in the contact list (422) using published updates to generate state messages for those users subscribing to contacts using the conference system (100). |
