Abstract

To provide the bit stream with some level of protection against channel errors, standard image and video techniques add a controlled amount of redundancy. This redundancy may take the form of resynchronization makers which enable the decoder to restart the decoding process from a known state in the event of transmission errors. The Error Resilient Entropy Code(EREC) is a well known algorithm designed to reduce the added redundant information. We propose a more error robust algorithm, EREREC, for the bit stream of DCT and SPIHT based coding techniques, which greatly improves its ability to maintain the compressed image quality in the event of random errors. The simulation results of proposed algorithm shows that the quality of transmitted image is improved for the principal coding techniques.
