Systematic rate controller for MPEG-4 FGS video streaming
T.M. Liu, Wei Qi, H.-J. Zhang, F. Qi · 2002
This paper proposes a systematic rate controller (SRC) for streamed delivery of MPEG-4 FGS video over the Internet. It provides both coarse-grain and fine-grain scalability of rate adaptation to various user access rates, long-term or short-term bandwidth fluctuations, and bit-rate variations of streamed video in a general scope of time-scale. A state machine (SM) is developed to implement the SRC. The adaptation is realized through mode and state transitions of the SM.
