Mobile multimedia collaboration architecture and applications

Summary form only given. Recent advances in the Internet enabling technologies and wide deployment of broadband optical and wireless networks in both the core and access areas have led to rapid growth of real-time multimedia communications and collaborative computing applications over the Internet anytime and anywhere. The mobile multimedia collaboration enabled applications include networked healthcare, distributed data right management for digital content distribution, telematics, and 3G/4G/wireline network convergence. These mobile multimedia collaborative networking and computing applications are recently made possible due to widely deployed broadband Internet (e.g. IP-over-SONET) and last-mile broadband technologies (e.g., ADSL/DSL and cable modem), the maturity of a widely accepted application layer signaling protocol (session initiation protocol (SIP)), and availability of high-power and smart mobile devices. These mobile multimedia collaboration enabled applications share a common core application requirement set, referred to as "5R" requirements, i.e., "right data sent to right person at right time in right form at right cost". This 5R requirement set basically covers technical challenges of security, QoS, privacy protection, performance, mobility and costs from layer 1 to layer 7. In this talk, we first discuss the concept of mobile multimedia collaboration and its enabled applications as described above. We then use distributed data right management (DRM) for secure digital content distribution as an example to illustrate 5R requirements. We conclude the talk by identifying challenges of meeting the 5R requirements as well as reviewing the progress of 5R implementation under mobile broadband Internet networking infrastructure.
