A novel rate-optimal rate allocation algorithm is proposed for parallel transmission of scalable images in multi-channel
systems. Scalable images are transmitted via fixed-length packets. The proposed algorithm selects a
subchannel as well as a channel code rate for each packet, based on the signal-to-noise ratios (SNR) of the
subchannels. The resulting scheme provides unequal error protection of source bits. Applications to JPEG2000
transmission show that significant UEP gains are achieved over equal error protection (EEP) schemes.
In this paper, a robust image transmission scheme based on JPEG2000 is proposed for packet erasure channels. Error resilience functionalities provided by JPEG2000 are utilized to control the source coding efficiency and the robustness according to channel conditions. Furthermore, together with the proposed interleaving scheme, some erasures can be recovered. Experimental results show the effectiveness of the scheme.
