Real-time distributed multi-party/multi-stream systems are becoming more popular in many areas such as 3D tele-immersion, multi-camera conferencing and security surveillance. However, the construction of such systems in large scale is impeded by the huge demand of computing and networking resources and the lack of a simple yet powerful networking model to handle interconnection, scalability and quality of service (QoS) guarantees. We make two main contributions in the paper: (1) we propose a novel generalized ViewCast model for multi-party/multi-stream video-mediated systems that fills the gap between high-level user interest and low level per-stream management, and (2) we demonstrate the ViewCast model by applying it to the multi-party 3D Tele-Immersive (3DTI) collaboration among geographically dispersed users. More specifically, we show how the ViewCast model is used in supporting stream data dissemination, coordination and QoS management among multiple 3D tele-immersive environments. We present our experimental results in both real implementation and simulation to show that our ViewCast-based solution achieves high efficiency, scalability, and quality in supporting multi-party 3DTI collaboration.
