Wireless multimedia evaluation facility

随着无线通信和移动的网络技术的发展，无线多媒体流媒体系统近年来受到了许多研究小组的关注。这主要是由于其潜在的音频和视频流应用，例如音频和视频会议，实时视频分发以及远程虚拟环境探索，这被视为许多多媒体相关应用的基础，例如关键条件监控，虚拟培训，虚拟指南商场，在线游戏和视频传感器监控，仅举几例。渥太华大学目前对无线多媒体流协议和算法的评估仅通过模拟或简单的自定义场景和硬件来执行。需要在真实的场景上实现和测试多媒体技术和方案，以便获得只有真实的测试床基础设施才能提供的重要测量和反馈。该提案的主要目标是创建一个持久的无线多媒体研究基础设施，渥太华大学的几个研究小组可以使用它来构建和测试应急准备应用程序以及其他多媒体相关项目的协作解决方案。在这个多媒体研究基础设施中，研究人员将能够通过高端3D渲染工作站和高清晰度显示器以及用于应急准备和监测应用的多显示器资源执行与其项目相关的所有多媒体任务，并为研究人员提供无线视频采集，捕获和图像处理工具。该基础设施还将充当多媒体分发点，其中可扩展数量的用户可以连接所提供的资源和/或应用程序并与之远程交互。

With the advances of wireless communication and mobile networking, wireless multimedia streaming systems have received a great deal of attention from several research groups in recent years. This is mainly due to their potential audio and video streaming applications such as audio and video conference, live video distribution, as well as remote virtual environment exploration, which is viewed as the basis for a number of multimedia related applications such as  critical conditions monitoring, virtual training, virtual guide malls, online gaming, and video-sensor surveillance,  just to mention a few. Current evaluation of wireless multimedia streaming protocols and algorithms at the University of Ottawa is performed only through simulations or simple custom scenarios and hardware. There is a need to implement and test multimedia techniques and schemes over real scenarios in order to get important measurements and feedback that only a real test bed infrastructure can provide. The main objective of this proposal is to create an enduring wireless multimedia research infrastructure that several research groups at the University of Ottawa can use to build and test collaborative solutions for emergency preparedness applications as well as other multimedia related projects. In this multimedia research infrastructure, researchers would be able to perform all multimedia tasks related to their projects through high-end 3D rendering workstations and high definition displays and multi-display resources for emergency preparedness and monitoring applications, as well as provide researchers wireless  video acquisition, capture and image processing tools. This infrastructure would act also as a multimedia distribution point, where a scalable number of users can connect and remotely interact with the provided resources and/or applications.
