Distributed multimedia streaming over ubiquitous networks has gained tremendous momentum in recent years. However, the streaming of multimedia content under the current Internet infrastructure faces rigorous challenges in term of scalability issues. The collaborative streaming technique proposed in this project is an answer to such a challenge. The research will be led by the applicant who has had extensive experiences in multimedia signal processing, wired and wireless communication, and embedded system development, in both industrial and academic environments. Distributed Multimedia Streaming with Visual Sensor Networks will focus on the following key research areas: (1) visual sensor network, (2) multimedia signal processing, (3) on-demand region-of-interest zooming, (4) distributed multimedia streaming over ubiquitous networks, and (5) peer-to-peer overlay content routing and security. In addition, two sub-projects will be investigated: (1) multimedia gateways, and (2) smart projectors. This proposed infrastructure represents a complete end-to-end solution for media content acquisition, communication, and display. This project aims to develop enabling technology to make the best and innovative use of today's network infrastructure for multimedia content distribution. The generic nature of the proposed streaming techniques makes it suitable for live broadcasting, e-entertainment, telemedicine, distance education, and multi-site videoconferencing. The short-term goal of this project is to decentralize the computation and bandwidth loads for multimedia applications over the existing internet infrastructure, while long-term goal is to promote Canada as a global leader in multimedia communication.

近年来，泛在网络上的分布式多媒体流媒体获得了巨大的发展势头。然而，在当前的互联网基础设施下，多媒体内容的流媒体在可扩展性方面面临着严峻的挑战。本项目中提出的协作流技术就是对这一挑战的回答。该研究将由在工业和学术环境中在多媒体信号处理、有线和无线通信以及嵌入式系统开发方面拥有丰富经验的申请者领导。基于视觉传感器网络的分布式多媒体流技术将主要研究以下几个方面：(1)视觉传感器网络，(2)多媒体信号处理，(3)按需感兴趣区域缩放，(4)泛在网络上的分布式多媒体流，(5)对等覆盖内容的路由和安全。此外，还将调查两个子项目：(1)多媒体网关和(2)智能投影仪。这一提议的基础设施代表了针对媒体内容获取、通信和显示的完整的端到端解决方案。该项目旨在开发使能技术，以便以最佳和创新的方式利用当今的网络基础设施来分发多媒体内容。拟议的流媒体技术的一般性使其适用于现场直播、电子娱乐、远程医疗、远程教育和多站点视频会议。该项目的短期目标是通过现有的互联网基础设施分散多媒体应用程序的计算和带宽负载，而长期目标是促进加拿大成为多媒体通信领域的全球领导者。
