Abstract

In order to improve unequal error protection (UEP) for compressed images, a novel rateless transmitting scheme is proposed in this paper. Based on 3GPP Raptor codes, this scheme can accurately match the image with different priority to ensure the efficiency and reliability. These Raptor codes have the linear complexity of encoding and decoding. In addition, a new framework called Short Interweaving Systematic Raptor (SISR) codes is proposed. Based on Markov process, the theoretical analysis of degree distribution design is given. Simulation results show that, compared to the traditional Raptor code, SISR can prominently improve the PSNR to obtain better image quality with different packet loss rate.
