Distributed multimedia streaming with visual sensor networks

点击翻译按钮获取中文摘要

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.
