Experimental Partnership - Internet Interactive Team Video

EIA-0071954John R.KenderColumbia University TITLE：实验伙伴关系：自适应交互团队视频该项目将为小组工作和/或小组学习创建一个协作虚拟环境，在该环境中，与指导、设计或团队工作的预先讨论有关的语义结构的视频以高效和自适应的方式通过不同的互联网链接传送到不同的平台。所提出的系统将能够：测量语义摘要和索引对视频资源的访问和使用的有效性，测量语义摘要和索引对视频资源的访问和使用的有效性，测量启发式预测和监控团队工作动作将对视频交付产生的服务质量影响，以及测量系统资源管理算法的成功程度，以完善和逐步地将视频片段提炼成具有不同能力的客户的缓存，这些缓存来自在不同负载下受到资源竞争的服务器集群。此外，这个项目将提供一个有效的分布式环境，用于协作和教育目的--一个将在PI自己的课程中进行测试的环境。

EIA-0071954John R. KenderColumbia UniversityTITLE: Experimental Partnership: Adaptive Interactive Team VideoThis project will create a collaborative virtual environment for group work and/or group study, in which semantically structured videos concerned with instruction, design, or prior discussion of a team effort are delivered over heterogeneous Internet links to heterogeneous platforms in an efficient and adaptive manner. The proposed system will enable: the measurement of the effectiveness of semantic summarization and indexing on the access and use of video resources, the measurement of the effectiveness of semantic summarization and indexing on the access and use of video resources, the measurement of the quality of service effects which heuristic forecasting and monitoring of team work actions will have on video delivery, and the measurement of the degree of success of system resource management algorithms for the perfecting and progressive refining of video segments into the caches of clients with varying capabilities from a server cluster subject to resource contention under varying loads. Additionally, this project will provide an efficient distributed environment useful for collaborative and educational purpose in its own right-one that will be tested in the PI's own courses.
