摘要：
The hierarchical structure of JPEG2000 stream calls for unequal error protection (UEP) schemes to achieve robustness efficiently. In this paper, a novel unequal error protection scheme is proposed for JPEG2000 image transmission, which encodes each bit-plane with ERAC of different code rate. Comparing with UEP schemes based on channel coding, the proposed scheme reserves the structure of JPEG2000 standard streams and avoids complicate channel framing process. Comparison with published equal error protection scheme proves the effectiveness of this method.
