Abstract
This paper presents a wavelet transmultiplexer based communication system for the transmission of Digital Cinema streams over wireless channels. To this aim, we adopt the tools of the JPEG2000 Wireless (JPWL) standard. We implement an unequal error protection (UEP) scheme that relies on forward error correction (FEC) channel coding supported by a proper unequal distribution of the transmission power (UPD) among JPWL coding units. In particular, we show that an appropriate combination of Reed-Solomon (RS) coding and UPD on the image data, can greatly improve the average PSNR of the reconstructed frames, in case of transmission over wireless channels with both sparse and packet error statistics, such as those provided by satellite broadcasting and Wireless MAN standards as WiMAX..
