Optimal Quality Adaptation for MPEG-4 Fine-Grained Scalable Video

by Taehyun Kim, Mostafa H. Ammar - in Proc. IEEE INFOCOM’03 , 2003

approaches that are capable of adapting to changing network conditions in real time. In this paper, we describe a new scalable video-coding framework that has been adopted recently by the MPEG-4 video standard. This new MPEG-4 video approach, which is known as Fine-Granular-Scalability (FGS), consists of a

Fine-Grained Scalable Video Caching for Heterogeneous Clients

by Jiangchuan Liu, Jianliang Xu, Xiaowen Chu
"... Abstract—Much research has focused on caching adaptive videos to improve system performance for heterogeneous clients with diverse access bandwidths. However, existing rate-adaptive caching systems, which are based on layered coding or transcoding, often suffer from a coarse adaptation and/or a high ..."

The proposed framework is both network-aware and media-adaptive; i.e., the clients can be of heterogeneous

Proxy cache management for fine-grained scalable video streaming

by Jiangchuan Liu, Xiaowen Chu, Jianliang Xu - Proceedings of IEEE INFOCOM’04, Hong Kong , 2004
"... Abstract- Caching video objects at proxies close to clients has attracted a lot of attention in recent years. To meet diverse client bandwidth conditions, there have been research efforts to combine proxy caching with video layering or transcoding. Nevertheless, these adaptive systems suffer from ei ..."

employs the MPEG-4 Fine-Grained Scalable (FGS) video with post-encoding rate control. We demonstrate that the proposed framework is both network aware and media adaptive: clients can be of heterogeneous streaming rates, and the backbone bandwidth consumption can be adaptively controlled. We also examine

Implementation of Adaptive Streaming of Stored MPEG-4 FGS Video over TCP

Rate-distortion bounds for motion-compensated rate scalable video coders

by Gregory W. Cook, J. Prades-nebot, Edward J. Delp - International Conference on Image Processing (ICIP , 2004
"... In this paper, we derive and evaluate theoretical ratedistortion performance bounds for scalable video compression algorithms which use a single motion-compensated prediction (MCP) loop. These bounds are derived using rate-distortion theory based on an optimum mean-square error (MSE) quantizer. By s ..."
