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. ...
