Abstract

The structure of JPEG2000 stream is applicable to unequal error protection (UEP) scheme to save the bandwidth. In this paper, a novel unequal error protection scheme which encodes each quality layer with ERAC of different code rates is proposed. Compared with UEP schemes based on sub-band, the proposed scheme reserves the structure of JPEG2000 standard stream and avoids complicate channel framing process. Simulation results show that performance of proposed scheme improves about ldB with the same packet error rate.
