Optimal coding of multilayer and multiversion video streams
收藏 引用
IEEE TRANSACTIONS ON MULTIMEDIA 2008年 第1期10卷 121-131页
作者: Hsu, Cheng-Hsin Hefeeda, Mohamed Simon Fraser Univ Sch Comp Sci Surrey BC V3T 0A3 Canada
Traditional video servers partially cope with heterogeneous client populations by maintaining a few versions of the same stream with different bit rates. More recent video servers leverage multilayer scalable coding t... 详细信息

Source fidelity over fading channels: Performance of erasure and scalable codes
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2008年 第7期56卷 1080-1091页
作者: Zachariadis, Konstantinos E. Honig, Michael L. Katsaggelos, Aggelos K. NW Univ Kellogg Sch Management Evanston IL 60201 USA NW Univ Dept Elect Engn & Comp Sci Evanston IL 60208 USA
We consider the transmission of a Gaussian source through a block fading channel. Assuming each block is decoded independently, the received distortion depends on the trade-off between quantization accuracy and probab... 详细信息

Streaming of scalable h.264 videos over the Internet
收藏 引用
MULTIMEDIA TOOLS AND APPLICATIONS 2008年 第3期36卷 303-324页
作者: Kantarci, Aylin Ege Univ Dept Comp Engn TR-35100 Izmir Turkey
To investigate the benefits of scalable codecs in the case of rate adaptation problem, a streaming system for scalable H.264 videos has been implemented. The system considers congestion level in the network and buffer... 详细信息

Union of MDCT Bases for Audio coding
收藏 引用
IEEE TRANSACTIONS ON AUDIO SPEECH AND LANGUAGE PROCESSING 2008年 第8期16卷 1361-1372页
作者: Ravelli, Emmanuel Richard, Gal Daudet, Laurent Univ Paris 06 Inst Jean le Rond Alembert LAM F-75015 Paris France GET ENST Tlcom Paris TSI Dept F-75014 Paris France
This paper investigates the use of sparse overcomplete decompositions for audio coding. Audio signals are decomposed over a redundant union of modified discrete cosine transform (MDCT) bases having eight different sca... 详细信息

Efficient peer assignment for low-latency transmission of scalable coded images
收藏 引用
JOURNAL OF COMMUNICATIONS AND NETWORKS 2008年 第1期10卷 79-88页
作者: Su, Xiao Wang, Tao San Jose State Univ Dept Comp Engn San Jose CA 95192 USA Synopsys Inc Mountain View CA USA
In this paper, we propose efficient peer assignment algorithms for low-latency transmission of scalable coded images in peer-to-peer networks, in which peers may dynamically join and leave the networks. The objective ... 详细信息
