- Network impairments such as delay and packet losses have severe impact on the presentation quality of many predictive video sources. Interleaved Source Coding (ISC) [5][6][7] is one of the error resilient coding methods for predictive video coded frames transmitted over a single erasure channel. ISC has shown to significantly improve the overall quality of predictive coded video stream over a lossy channel [5][6][7]. In this paper, ISC is evaluated over channels with memory. In particular, we analyze the impact of packet correlation [11][13] of the popular Gilbert model on ISC-based packet video over a wide range of packet loss probabilities. Simulations have shown that ISC advances the traditional method as either the loss rate increases or the packet correlation decreases. © 2006 IEEE.
