Abstract

Private Multimedia Network (PMN) complements, and is an improved alternative to digital videoconferencing and multimedia delivery systems. PMN's desktop and meeting room delivery system is designed to support the exponential growth of enterprise team-based initiatives. PMN provides 'one-stop-shopping' for the full multimedia rubric. It delivers user-friendly control and cost/effective TV and broadcast quality videoconferencing and other multimedia services to organizations with 'critical mass' campuses and building complexes. Though digital systems dominate the videoconferencing marketplace, PMN's hybrid digital/analog architecture has no digital peer in breadth or quality of service within or between campuses. The novel architecture leverages advances in analog video short-haul technology, digital long-haul technology, and telephony audio and control technology to deliver four-level multimedia services: 1) premise; 2) campus; 3) multi-site; and 4) ubiquitous (any site with ITU compatible multimedia equipment (e.g., videoconferencing) and communication links). On balance, the price/performance afforded by PMN's centralized Telco-based control and audio delivery combined with its decentralized broadcast quality video distribution raise videoconferencing and other multimedia services to a new level of ubiquity. Just as telephones and PC LANs, PMN delivers expensive Boardroom and mobile cart videoconferencing capabilities to every desktop via existing multimedia wall plates. The key phases for this invention are: Lip-synchronization across differing network communication links and protocols; Ubiquitous multimedia service; Cost/effective room and desktop deployment; Telco control and audio; Broadcast quality video; Isochronous Quality; Centralized control and distributed operation; and Interoperable architecture.
