Server selection in large-scale video-on-demand systems
Niklas Carlsson, Derek L. Eager
Article No.: 1
Video on demand, particularly with user-generated content, is emerging as one of the most bandwidth-intensive applications on the Internet. Owing to content control and other issues, some video-on-demand systems attempt to prevent downloading and...
The article addresses the problem of copyright protection for 3D motion-captured data by designing a robust blind watermarking mechanism. The mechanism segments motion capture data and identifies clusters of 3D points per segment. A watermark can...
DSI: A model for distributed multimedia semantic indexing and content integration
Article No.: 3
Considerable research has been done on the content-based multimedia delivery and access in distributed data repositories. As noted in the literature, there is always a trade-off between multimedia quality and access speed. In addition, the overall...
Effect of compressed offline foveated video on viewing behavior and subjective quality
Marcus Nyström, Kenneth Holmqvist
Article No.: 4
Offline foveation is a technique to improve the compression efficiency of digitized video. The general idea behind offline foveation is to blur video regions where no or a small number of previewers look without decreasing the subjective quality...
Real-time H.264 video encoding in software with fast mode decision and dynamic complexity control
Yuri V. Ivanov, C. J. Bleakley
Article No.: 5
This article presents a novel real-time algorithm for reducing and dynamically controlling the computational complexity of an H.264 video encoder implemented in software. A fast mode decision algorithm, based on a Pareto-optimal macroblock...
