This article presents the results of a study that explored the human side of the multimedia experience. We propose a model that assesses quality variation from three distinct levels: the network, the media and the content levels; and from two...
Statistical admission control using delay distribution measurements
Kartik Gopalan, Lan Huang, Gang Peng, Tzi-Cker Chiueh, Yow-Jian Lin
Growth of performance sensitive applications, such as voice and multimedia, has led to widespread adoption of resource virtualization by a variety of service providers (xSPs). For instance, Internet Service Providers (ISPs) increasingly differentiate...
Middleware for streaming 3D progressive meshes over lossy networks
H. Li, M. Li, B. Prabhakaran
Streaming 3D graphics have been widely used in multimedia applications such as online gaming and virtual reality. However, a gap exists between the zero-loss-tolerance of the existing compression schemes and the lossy network transmissions. In this...
Process prioritization using output production: Scheduling for multimedia
Yoav Etsion, Dan Tsafrir, Dror G. Feitelson
Desktop operating systems such as Windows and Linux base scheduling decisions on CPU consumption; processes that consume fewer CPU cycles are prioritized, assuming that interactive processes gain from this since they spend most of their time waiting...
A graphics architecture for high-end interactive television terminals
Pablo Cesar, Petri Vuorimaa, Juha Vierinen
This article presents a graphics software architecture for next-generation digital television receivers. We propose that such receivers should include a standardised Java-based procedural environment capable of rendering 2D/3D graphics and video, and...
