Abstract

In this paper, we present a novel error resilient combined source-channel coding scheme suitable for mobile video applications. Several well-known methods from the areas of image and channel coding are combined to provide a system for transmitting low bit-rate video over mobile communication channels. The system is based on the use of Rate Compatible Punctured Convolutional codes that apply Unequal Error Protection to the H.263 source coder. An attempt at retaining synchronisation is made using the Error Resilient Entropy Coder to limit the propagation of bit errors in the macroblocks caused by the presence of burst errors in the mobile channel. Furthermore, the H.263 decoder has several error concealment methods to remove residual errors. Simulation results for the scheme are obtained for two QCIF sequences over Gaussian, Rayleigh and Rician channels using BPSK modulation.
