Abstract

3D Teleimmersive (TI) environments have gained significant attention as they show promising results for a wide number of applications. These environments are usually distributed and multi platform which makes performance analysis and monitoring difficult. We present a Unified Time Service (UTS) and its measurement framework for evaluating components in terms of their reflected QoS (e.g. delay). Then we utilize UTS to analyze the delay introduced by the virtualized rendezvous points (RP) in the H-MEDIA TI system. We find that the delay overhead heavily depends on frame sizes of the 3D video streams.
