This Small Business Innovation Research (SBIR) Phase I project focuses on the implementation, testing, and refinement of a hybrid distributed / traditional system for broadcasting live and pre-recorded content to large online audiences at low cost. Traditional approaches to streaming media online are not well suited for delivering television-style "linear" feeds to large audiences. The primary constraint is that the bandwidth costs shouldered by the broadcaster increase in lock step with increasing audience size -- the more people who watch; the more it costs the broadcaster. Peer-to-peer systems can shift content distribution costs from publishers to end-consumers interested in obtaining a copy of that content. This proposal directly addresses the issue of guaranteeing a specific quality of service (a particular streaming bit rate) to end-users, regardless of their ability to repeat the broadcast. By segmenting the broadcast stream into components and augmenting the broadcast system with a traditional online broadcast solution, the bandwidth bottleneck can be removed, providing consumers with a high quality viewing experience, while continuing to significantly reduce broadcaster bandwidth costs.The commercial potential of this project is significant. By implementing a unique "augmentation server" architecture to deliver those portions of a broadcast signal that can not be effectively transmitted in a distributed manner, the resulting hybrid distributed / traditional online broadcast solution will combine lower cost with increased quality. Once proven, this combination of features is likely to prove attractive to broadcasters who are searching for ways to effectively utilize the Internet to reach larger audiences.

这项小型企业创新研究（SBIR）I阶段项目着重于以低成本向大型在线受众广播的混合分布式 /传统系统的实施，测试和完善。 在线流媒体的传统方法不适合向大型观众提供电视风格的“线性”供稿。主要限制是，随着受众群体的增加，广播公司锁定步骤增加的带宽成本 - 观看的人越多；它的成本越多。点对点系统可以将内容分配成本从发行商转移到有兴趣获得该内容副本的最终消费者。 该建议直接解决了向最终用户保证特定服务质量（特定流率比特率）的问题，无论其重复广播的能力如何。通过将广播流分割成组件并通过传统的在线广播解决方案增强广播系统，可以删除带宽瓶颈，从而为消费者提供高质量的观看体验，同时继续显着降低广播公司的带宽成本。很重要。通过实施独特的“增强服务器”体系结构来传递无法以分布式方式有效传输的广播信号的部分，由此产生的混合分布式 /传统的在线广播解决方案将较低的成本与质量提高相结合。一旦证明，这种功能的组合可能会证明对正在寻找有效利用互联网吸引更多受众的方法的广播公司有吸引力。
