A Low Complexity Error Concealment Scheme for MPEG-4 Coded Video Sequences
MPEG coded bit streams are very sensitive to channel disturbances due to variable length coding. A single bit error can lead to very severe degradation in that part or entire slice of the image. This is of particular concern in video over wireless networks. Error concealments methods, implemented at the decoder side, present one way of dealing with this problem. In this paper a low complexity error concealment scheme for MPEG4 video sequences is proposed. Spatial and temporal information is used to reconstruct the corrupted slice/frame. The proposed schemes are very simple to implement and are well suited for real time video decoding applications that are used in handheld devices. Performance of the schemes for various BER (Bit Error Rates) is compared with the existing schemes.
