Achieving simultaneous distribution control and privacy protection for Internet media delivery
Songqing Chen, Shiping Chen, Huiping Guo, Bo Shen, Sushil Jajodia
Article No.: 9
DOI: 10.1145/1352012.1352013

Massive Internet media distribution demands prolonged continuous consumption of networking and disk bandwidths in large capacity. Many proxy-based Internet media distribution algorithms and systems have been proposed, implemented, and evaluated to...

Feature synthesized EM algorithm for image retrieval
Rui Li, Bir Bhanu, Anlei Dong
Article No.: 10
DOI: 10.1145/1352012.1352014

As a commonly used unsupervised learning algorithm in Content-Based Image Retrieval (CBIR), Expectation-Maximization (EM) algorithm has several limitations, including the curse of dimensionality and the convergence at a local...

Audio keywords generation for sports video analysis
Min Xu, Changsheng Xu, Lingyu Duan, Jesse S. Jin, Suhuai Luo
Article No.: 11
DOI: 10.1145/1352012.1352015

Sports video has attracted a global viewership. Research effort in this area has been focused on semantic event detection in sports video to facilitate accessing and browsing. Most of the event detection methods in sports video are based on visual...

Multimedia streaming using multiple TCP connections
Sunand Tullimas, Thinh Nguyen, Rich Edgecomb, Sen-ching Cheung
Article No.: 12
DOI: 10.1145/1352012.1352016

In recent years, multimedia applications over the Internet become increasingly popular. However, packet loss, delay, and time-varying bandwidth of the Internet have remained the major problems for multimedia streaming applications. As such, a...

A scalable and extensible segment-event-object-based sports video retrieval system
Dian Tjondronegoro, Yi-Ping Phoebe Chen, Adrien Joly
Article No.: 13
DOI: 10.1145/1352012.1352017

Sport video data is growing rapidly as a result of the maturing digital technologies that support digital video capture, faster data processing, and large storage. However, (1) semi-automatic content extraction and annotation, (2) scalable...

Distributed musical performances: Architecture and stream management
Roger Zimmermann, Elaine Chew, Sakire Arslan Ay, Moses Pawar
Article No.: 14
DOI: 10.1145/1352012.1352018

An increasing number of novel applications produce a rich set of different data types that need to be managed efficiently and coherently. In this article we present our experience with designing and implementing a data management infrastructure...

On the accuracy and complexity of rate-distortion models for fine-grained scalable video sequences
Cheng-Hsin Hsu, Mohamed Hefeeda
Article No.: 15
DOI: 10.1145/1352012.1352019

Rate-distortion (R-D) models are functions that describe the relationship between the bitrate and expected level of distortion in the reconstructed video stream. R-D models enable optimization of the received video quality in different network...

Multimedia streaming via TCP: An analytic performance study
Bing Wang, Jim Kurose, Prashant Shenoy, Don Towsley
Article No.: 16
DOI: 10.1145/1352012.1352020

TCP is widely used in commercial multimedia streaming systems, with recent measurement studies indicating that a significant fraction of Internet streaming media is currently delivered over HTTP/TCP. These observations motivate us to develop...
