Exploring interest correlation for peer-to-peer socialized video sharing

Xu Cheng, Jiangchuan Liu
2012 ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP)  
We address a series of key design issues to realize the system, including a bi-layer overlay, an efficient indexing scheme, a delay-aware scheduling mechanism, and a prefetching strategy leveraging interest  ...  to improve the playback quality, and a cluster-aware prefetching strategy that enables delay-minimized smooth transition between video playbacks.  ...  We believe that this is mainly due to the delay-aware scheduling mechanism and cluster-aware prefetching.

A Video Timeline with Bookmarks and Prefetch State for Faster Video Browsing

Axel Carlier, Vincent Charvillat, Wei Tsang Ooi
2015 Proceedings of the 23rd ACM international conference on Multimedia - MM '15  
Reducing seek latency by predicting what the users will access is important for user experience, particularly during video browsing, where users seek frequently to skim through a video.  ...  This paper proposed a different approach whereby the prefetch hit rate is improved by biasing the users to seek to prefetched content with higher probability, through changing the video player user interface  ...  For instance, the content-aware timeline [14] extracts keyframes with content analysis and plays a video snippet around these points when the user scrubs the timeline.  ...
