System architecture for error-resilient, embedded JPEG2000 wireless delivery

With new, third generation mobile terminals several multimedia-based applications will be soon available. The reliable transmission of audiovisual content will probably become one of the most asked services. On the other hand, when wireless delivery is addressed, it would be desirable to reach very high compression ratio keeping a good image perceptual quality. With these requirements the choice of JPEG2000 as the source encoding stage assures excellent results. However a non-ideal wireless network could seriously affect the received image decoding, despite JPEG2000´s error resilience capabilities. In this paper a flexible DSP/FPGA system with high error-resilience features is proposed. Experimental results show very promising visual quality, with a limited complexity overhead, even in the presence of a mean loss rate of 10%.
