With the increasing demand for digital media, there has been significant interest in the deployment of image and video compression techniques. However, the presence of variable-length codes in most of the compression standards like the JPEG and the MPEG are highly sensitive to channel noise. Any bit of transmission error will cause the decoder to lose synchronization and the reconstructed image quality will be significantly degraded. Much effort has been invested in R&D to build error resilience into the compressed bit-stream and ensure improving the quality of image/video wireless transmission. We propose a novel DCT -based [1] bit plane error resilient entropy coding scheme, which can control and minimize the error propagation effect. The compressed rate can be similar with the JPEG standard. In addition, it uses only 18 VLC symbols. Memory requirement and power consumption can then be minimized. Base on simulation results, the proposed coding scheme can achieve high image quality (PSNR = 29.82dB) even at bit error rate of 10-3. These performances can meet various wireless multimedia system requirements.
