Defining user perception of distributed multimedia quality
Stephen R. Gulliver, Gheorghita Ghinea
Pages: 241-257
DOI: 10.1145/1201730.1201731
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
Pages: 258-281
DOI: 10.1145/1201730.1201732
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
Pages: 282-317
DOI: 10.1145/1201730.1201733
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
Pages: 318-342
DOI: 10.1145/1201730.1201734
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
Pages: 343-357
DOI: 10.1145/1201730.1201735
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...

Metadata handling: A video perspective
Chitra L. Madhwacharyula, Marc Davis, Philippe Mulhem, Mohan S. Kankanhalli
Pages: 358-388
DOI: 10.1145/1201730.1201736
This article addresses the problem of processing the annotations of preexisting video productions to enable reuse and repurposing of metadata. We introduce the concept of automatic content-based editing of preexisting semantic home video metadata. We...
