In the multiple description coding (MDC), the source is decomposed into two or more descriptions, and then transmitted over on/off channels. At the receiver end, each description can be reproduced with acceptable side distortion; reconstructed signals with lower central distortion can be accomplished by exploiting more descriptions. In order to apply the classical MDC over error-prone channels, we...
Error resilient multiple description coding (ERMDC) consists of a robust encoder and an enhanced decoder. It was developed to achieve higher error tolerance than the classical multiple description coding (MDC) for error-prone channels when bit errors of one description exceeded the error correction capability of the applied forward error correction (FEC) code. In this paper, ERMDC is extended to Rayleigh...
Multiple description coding (MDC) is applied to achieve acceptable performance when only one single description is received correctly, and better resolution of the source when all descriptions are received correctly. In previous work, the description with bit errors is either discarded completely, or estimated by using complicated algorithms. A new central receiver is proposed in this paper so as...
Multiple description coding (MDC) can achieve acceptable performance with only one single correct description, and lower distortion of the source when more descriptions are received correctly. In our previous work, we assumed that because of noisy channel, bit errors were introduced into one description, but the other one was received correctly. Based on this assumption, an enhanced central decoder...
