Abstract

In this paper, a new bi-directional error-resilient entropy coding (BEREC) technique is proposed which uses the beginnings and ends of fixed-length slots to synchronize variable-length blocks of data in two directions. In BEREC frames, every two variable-length blocks of data are grouped to generate one block-pair and placed in one fixed-length slot back-to-back using the similar searching strategy to that of the error-resilient entropy coding (EREC). Therefore, two blocks in one block-pair can be decoded in forward and backward directions separately. Compared to the EREC, the BEREC shows a significantly better performance of error robustness for noisy channels.
