摘要：

In this paper we present an efficient error concealment (EC) method for the fine granularity scalable (FGS) video transmission. The proposed EC method exploits both the temporal and spatial correlations in an FGS encoded bitstream. In our scheme, the temporal redundancy is used to improve the quality of contaminated regions, and the intensity of the temporal correlation in contaminated regions is estimated by exploiting the spatial correlation in the surrounding high-quality regions. To maximally utilize the spatial correlation for estimation, we also propose two interleaving patterns that can avoid packetizing the neighboring regions into the same packet. Experiments show that our EC method achieves very good performance and is robust to different bandwidths and different sequences.
