抜粋

Transmission of compressed video over error prone channels may result in packet losses or errors, which can significantly degrade the image quality. Such degradation even becomes worse in 1Seg video broadcasting, which is widely used in Japan and Brazil for mobile phone TV service recently, where errors are drastically increased and lost areas are contiguous. Therefore the errors in earlier concealed MBs (macro blocks) may propagate to the MBs later to be concealed inside the same frame (spatial domain). The error concealment (EC) is used to recover the lost data by the redundancy in videos. Aiming at spatial error propagation (SEP) reduction, this paper proposes a SEP reduction based EC (SEP-EC). In SEP-EC, besides the mismatch distortion in current MB, the potential propagated mismatch distortion in the following to be concealed MBs is also minimized. Compared with previous work, the experiments show SEP-EC achieves much better performance of video recovery in 1Seg broadcasting.
