| Abstract: | The main coding techniques of FGS and its fine granular scalability are presented in this paper as well as some of its major advanced features and improvement. Further, current work on FGS error- robust characteristics and its adaptation to time- varying- bandwidth network is discussed, with some of my work listed. Unicast and multicast video streaming frameworks based on FGS are also described. |
