Abstract

This paper presents a novel degressive error protection (DEP) algorithm adaptive to time varying packet loss rate for robustly transporting MPEG-4 fine granularity scalability (FGS) bit-stream over the packet erasure networks. By exploiting the embedded nature of FGS enhancement-layer bit-stream, a rate-distortion (R-D) optimization framework is developed to optimally partition the FGS enhancement-layer bit-stream into blocks and then to apply DEP to blocks by forward error correction (FEC). Experimental results show that this algorithm achieves graceful degradation of video quality in a wide range of packet loss rates.
