Synchronized Dissemination Framework for Supporting High-Quality Tele-Immersive Shared Activity

My Ph.D. thesis aims to develop a synchronized dissemina-tion framework for supporting high-quality tele-immersive shared activity (TISA). Synchronization in TISA is compli-cated by (a) the multi-modal, bandwidth-savvy and timing-dependent media streaming over shared network resources, and (b) the delay-sensitive and interaction-critical nature of TISA in the real two-site and multi-site applications. This paper provides an outline of my thesis which includes four major contributions: (1) proposing a generalized layered framework for multi-stream synchronization sourced at one or multiple sites, (2) presenting an adaptive media packet scheduling scheme based on multi-stream timing correla-tions under Internet dynamics, (3) proposing a synchronized multicast topology based on diverse user interests, and (4) studying human subjective satisfactions to guide the system adaptation. This study is expected to output research re-sults significant for next-generation systems, where timing-dependent media multi-modality is critical
