Compressed multimedia data is highly vulnerable to error propagation in noisy channel and even a single bit error can cause severe image distortion. To improve the reliability of image transmission, in this paper we propose a practical JPEG2000 based error resilient arithmetic coding (ERAC) scheme for wireless robust image transmission. Forbidden symbols are added at the encoder side and an efficient MAP sequence decoding method of ERAC is developed to estimate the original symbols. Furthermore, the error resilient performance of ERAC is intensively discussed. The entire scheme is designed and optimized on a fixed point DSP, which has already been successfully applicable to robust image transmission under complexity consideration. The experimental results demonstrate the effectiveness of our proposed scheme in improving the end-to-end reconstructed image quality 3 to 5 dB in PSNR at the expense of less than 5% redundancy.
