In this paper, we propose a video source coding scheme, called Supplementary Block based Encoding, to protect the propagation of the transmission errors over the network. Unlike the conventional source coding schemes, the proposed coder, for a macroblock in a frame, selects the two best matching blocks among several preceding frames. The best matching block is exploited for motion compensation of the current macroblock. The other block replaces the primary block in case of its loss during transmission at the decoder. This scheme has the advantages of reducing both the frequency and the impact of error propagation in comparision to related research. We implemented the proposed coder by modifying the H.263 standard source code and evaluated the performance through various simulations. The results show that the proposed scheme is more efficient than the H.263 baseline coder for both slow and fast motion video sequences.
