The broad goal of this work is to develop new systems and networking techniques to support time-sensitive distributed applications, using a best-effort commodity infrastructure. The research objectives of this work are related by a general theme of quality adaptation, the motivation of which is to address the conflict between time-sensitive applications and the best effort service model that still remains the sole option available to the vast majority of Internet users. We also aim to explore how to apply principles of context-aware computing to enhance the process of user and community oriented video production and distribution.
