Evaluation of Interleaved Source Coding (ISC) over Channel with Memory
Network impairments such as delay and packet losses have severe impact on the presentation quality of many predictive video sources. Interleaved source coding (ISC) is one of the error resilient coding methods for predictive video coded frames transmitted over single erasure channel. ISC has shown to significantly improve the overall quality of predictive coded video stream over a lossy channel. In this paper, ISC is evaluated over channels with memory. In particular, we analyze the impact of packet correlation 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 increase or the packet correlation decreases.
