Abstract

In this paper, we propose content-adaptive refined error concealment schemes for video transmission over packet lossy networks. The proposed spatial and temporal error concealment algorithms improve the reconstructed video quality at the common loss rates encountered on the networks. To reduce the computational complexity, the proposed schemes make use of the existing information of Intra prediction modes from the coded bit-stream for spatial error concealment. Neighboring macroblocks mode information is used to adapt the partition size of the lost macroblock to enhance the temporal error concealment performance. In addition, overlapped motion compensation is used to avoid the spatial discontinuities. A hybrid spatio-temporal concealment scheme is also proposed to use the appropriate algorithm for the lost macroblocks in the Inter frames. Experimental results demonstrate that the proposed schemes improve the concealment performance and reduce the structural degradations.
