, 2006 A wavelet-based videophone scheme proposed, where the video bits are Unequal Error Protection (UEP) using Irregular Convolutional Codes (IRCCs). The proposed system uses Adaptive Arithmetic Coding (AAC) for encoding the motion vectors and individual ...

, 2008 —Since the different bits of the compressed video sequence produced by the BBC’s wavelet-based video codec exhibit different error sensitivity, efficient Unequal Error Protection (UEP) schemes have to be used to ensure that the perceptually more ...

Unequal error protection of LT codes over noisy channels
, 2012 We propose a new unequal error protection (UEP) scheme for Luby Transform (LT) codes over additive white Gaussian noise (AWGN) channels. In contrast to the state-of-the-art UEP scheme for LT codes where the effective code rates are exploited for UEP, we ...

Design of Encoding Algorithm for Underwater Wireless Optical Communication Based on Spinal Code
Journal of Marine Science and EngineeringThe marine environment is complex and variable, with the absorption and scattering effects of seawater and turbulence causing significant attenuation of received optical signals and introducing random jitter, which limits the communication range and ...

A novel UEP scheme based upon rateless codes
, 2012 In this paper, we propose a novel method suitable for unequal error protection(UEP) and unequal recovery time (URT) properties, namely the Duplicating-Expanding Window Fountain(D-EWF) codes.

Rate-Distortion Optimization for Stereoscopic Video Streaming with Unequal Error Protection
EURASIP Journal on Advances in Signal Processing, 2008 We consider an error-resilient stereoscopic streaming system that uses an H.264-based multiview video codec and a rateless Raptor code for recovery from packet losses. One aim of the present work is to suggest a heuristic methodology for modeling the end-

Multilevel Block Coded Modulation with Unequal Error Protection
, 1997 Multilevel block coded modulation (BCM) schemes with unequal error protection (UEP) are investigated. These schemes are based on unconventional set partitions that greatly reduce the error coefficients associated with multi-stage decoding of conventional
