| Abstract: | With the development of Internet,more and more applications start to use the media streaming . The video scalable coding technique,one of core technology in media streaming,have been thought as the important study field. This paper fist provides an overview of the fine granularity scalabiliaty(FGS)video coding technique in the Amendment of the MPEG-4,and discusses the several extensible features of FGS coding and its defects. In addition,the research progress on fine granularity scalability video coding for Internet is analyzed. Finally,the state of arts and possible new directions of FGS are stated. |
