Protecting H.264/AVC Data-Partitioned Video Streams over Broadband WiMAX
Advances in Multimedia, 2012 Broadband wireless technology, though aimed at video services, also poses a potential threat to video services, as wireless channels are prone to error bursts. In this paper, an adaptive, application-layer Forward Error Correction (FEC) scheme protects H.

Multilevel Block Coded Modulation with Unequal Error Protection [PDF]
, 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

UEP Concepts in Modulation and Coding
Advances in Multimedia, 2010 First unequal error protection (UEP) proposals date back to the 1960's (Masnick and Wolf; 1967), but now with the introduction of scalable video, UEP develops to a key concept for the transport of multimedia data.

Improved Design of Unequal Error Protection LDPC Codes
EURASIP Journal on Wireless Communications and Networking, 2010 We propose an improved method for designing unequal error protection (UEP) low-density parity-check (LDPC) codes. The method is based on density evolution.

QoE Optimization of Video Multicast with Heterogeneous Channels and Playback Requirements [PDF]
, 2015 We propose an application-layer forward error correction (AL-FEC) code rate allocation scheme to maximize the quality of experience (QoE) of a video multicast. The allocation dynamically assigns multicast clients to the quality layers of a scalable video

Iranian Journal of Electrical and Electronic Engineering, 2009 The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP)
