In addition to generic VCR-like features, our custom-built Video-on-Demand architecture enabled us to provide advanced interactivity features such as bookmarking. We illustrate how such functionality may have a dramatic impact on how users consume content. A detailed discussion is also provided on how content distributors may turn this knowledge to their advantage, and thus increase the efficiency of their delivery networks.} } @article{brampton2008cew, title = {Characterising and Exploiting Workloads of Highly Interactive Video-on-Demand}, author = {Andrew Brampton and Andrew MacQuire and Michael Fry and Idris Rai and Nicholas J.

In addition to generic VCR-like features, our custom-built Video-on-Demand application provides advanced interactivity features such as bookmarking. The dramatic impact of such functionality on how users consume content is studied and analysed. We discuss in detail how this user behaviour can be exploited by content distributors to improve user experience. Specifically, we study how simple dynamic bookmark placement and interactivity-aware content pre-fetching and replication can reduce the impact of highly interactive media on CDN performance.} } @inproceedings{macquire2008acf, booktitle = {International workshop on Future Multimedia Networking (FMN)}, title = {A Case for Hybrid Content Distribution for Interactive Video-on-Demand}, author = {Andrew MacQuire and Andrew Brampton and Michael Fry and Nicholas Race and Laurent Mathy}, year = {2008}, month = {September}, }
