Providing Interactive VOD Services for Popular Video

本项目研究各种方案，为流行视频提供负担得起的交互式视频点播（VOD）服务。 这些视频包括"热点“新闻报道，流行的体育赛事， 听过的讲座或者最近上映的电影的第一个目标 本研究旨在了解各种资源之间的权衡 例如服务器I/O带宽、客户端缓冲区大小和客户端 I/O带宽。所有这些权衡问题都很重要， 设计视频服务器，因为在未来的多媒体 应用程序，服务提供商可能会补贴的成本， 在用户侧的机顶盒，如果它是成本有效的。第二 研究的目标是为用户提供交互式服务。 交互式服务，包括类似VCR的功能， 如暂停、恢复、倒带和前进，使任何内容可用 在指尖的触摸下。研究包括资源 提供及时互动服务的分配方案。 有关计划的详情，请参阅 网页 A HREF =“http://cs.smith.edu/~gao/research/ivod.html“提供 流行视频的交互式VOD服务/A。 作为多媒体网络领域的一个新的研究者， 我将专注于第一个目标，并为第二个目标搭建舞台 规划期间的目标。PI计划提交一份完整的 在规划期结束前提出建议。

This project studies various schemes that provide affordable and interactive Video-on-Demand (VOD) services for popular videos. These videos include ``hot'' news coverage, popular sport events, tapped lectures, or recently released movies. The first goal of the study is to understand the tradeoff among various resources such as server I/O bandwidth, client buffer size, and client I/O bandwidth. All these tradeoff issues are important in designing a video server since, in future multimedia applications, service providers might subsidize the cost of the set-top box at a user's side if it is cost effective. The second goal of the study is to provide interactive services to users. The interactive services, which include VCR like functions such as pause, resume, rewind and forward, make any content available under the touch of a fingertip. The study includes resource allocation schemes for providing timely interactive services. For a full description of the project, please refer to the web page A HREF = "http://cs.smith.edu/~gao/research/ivod.html"Providing interactive VOD services for popular videos/A. As a new researcher in the area of multimedia networks, the PI will focus on the first goal and set a stage for the second goal during the planning period. The PI plans to submit a full proposal by the end of the planning period.
