Adaptive high-quality video service for network-based multi-party collaboration
Sang Woo Han, JongWon Kim · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2005
Multi-party collaborative environments are extensively utilized for distance learning, e-science, and other events for distributed global collaboration. In such environments, improved media service is expected to improve QoE (quality of experience) by better participants' perception in collaboration session. In this paper, we design and implement a high-quality video service attempted to be operated with a multi-party collaborative environments, Access Grid (AG), over heterogeneous networks. The proposed service uses the combination of high-quality video formats, network monitoring, and network-adaptive transmission. Its primary application is to provide seamless high-resolution video delivery service by considering one-to-many aspect of video distribution in AG-based multi-party collaborative environments. The implementation results are evaluated over a multicast-enabled network testbed and the experiment results verify the improved video service capability.
