Broadcasting of digital cimema streams over wireless channels: a power-based unequal error protection approach
Article No.: 5, Pages 1 - 4
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.

Recommendations
A power-based unequal error protection system for digital cinema broadcasting over wireless channels
This paper deals with the efficient and robust wireless broadcasting of JPEG2000 digital cinema (DC) streams from studios to theatres. Several unequal error protection (UEP) techniques have been proposed in literature for the transmission of JPEG2000 ...
Optimized transmission of JPEG2000 streams over wireless channels
The transmission of JPEG2000 images over wireless channels is examined using reorganization of the compressed images into error-resilient, product-coded streams. The product-code consists of Turbo-codes and Reed-Solomon codes which are optimized using ...
Error-resilient transmission of quality-scalable images over wireless channels
A new strategy for robust wireless transmission of scalable images is proposed. The proposed scheme utilizes the quality-progressive structure of the scalable code-stream and optimally protects different quality layers based on channel conditions using ...
