Abstract :
MPEG-4 Fine Granularity Scalability (FGS) provides bandwidth adaptation and error resilience features for streaming applications. In this paper, by estimating the required computational power for FGS in a video encoding system, an efficient FGS implementation method is exploited. With the proposed hardware-oriented optimization approaches, a hardwired FGS block-level processing core is proposed to provide a cost-effective solution to FGS implementation. The proposed hardware core can support profile level 5, frame size 720×576, 30Hz, for real-time streaming applications at 54 MHz.
