Streaming fine-grained scalable video over packet-based networks

Abstract

This paper presents an efficient method for streaming video that has the attribute of fine-granular scalability (FGS), which is a video coding method currently undergoing the MPEG-4 standardization process. An overview of FGS coding is given followed by a description of some issues associated with streaming the FGS base and enhancement layers over packet-based networks such as the Internet. The overall structure of the streaming system is described, and the detailed functionality of the algorithm is presented including simulation results, showing how to regulate the transmission of FGS video over networks that have packet loss or bandwidth variations.
