Abstract

A novel video coding scheme based on leaky prediction is proposed and its superiority against conventional predictive video coding is demonstrated in environments with moderate to heavy packet loss. The strength of the scheme stems from the fact that it explicitly takes into account the two modes of operation (packet loss or no packet loss) at the decoder and optimizes the corresponding reconstruction filters together with the prediction filter at the encoder simultaneously. The prediction coefficient tends to be significantly smaller than the correlation coefficient between two corresponding frames.
