Abstract — In this paper, the computational complexity of MPEG-4 Fine Granularity Scalability (FGS) coding is analyzed to explore an efficient FGS implementation for video streaming applications. With the proposed hardware-oriented optimization approaches, a hardwired FGS block-level processing core is proposed to provide a cost-effective solution. It can be integrated into an existing MPEG-4 coding system to form an interactive video streaming system. By the proposed FGS coder with reordered coding flow, the streaming server can adaptively decide qualityenhanced region by selective enhancement according to both object information from encoding side and user-defined region from receiver side. The proposed hardware core can support FGS profile level 5, frame size 720x576, 30Hz, for real-time streaming applications at 54 MHz. I.
