Unequal Error Protected JPEG 2000 Broadcast Scheme with Progressive Fountain Codes
, 2012 This paper proposes a novel scheme, based on progressive fountain codes, for broadcasting JPEG 2000 multimedia. In such a broadcast scheme, progressive resolution levels of images/video have been unequally protected when transmitted using the proposed ...

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-

Practical LDPC coded modulation schemes for the fading broadcast channel with confidential messages
, 2014 The broadcast channel with confidential messages is a well studied scenario from the theoretical standpoint, but there is still lack of practical schemes able to achieve some fixed level of reliability and security over such a channel.

Unequal Error Protection QPSK Modulation Codes [PDF]
, 1992 The authors use binary linear UEP (LUEP) codes, in combination with a QPSK signal set and Gray mapping, to obtain new efficient block QPSK modulation codes with unequal minimum squared Euclidean distances.
