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.

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.

An efficient unequal error protection scheme for 3-D video transmission

, 2013
In this paper, we propose a new unequal error protection (UEP) scheme, called video packet partitioning for three-dimensional (3-D) video transmission.

Unequal Error Protection: An Information-Theoretic Perspective [PDF]

, 2009
An information-theoretic framework for unequal error protection is developed in terms of the exponential error bounds. The fundamental difference between the bit-wise and message-wise unequal error protection ( UEP) is demonstrated, for fixed-length ...

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks

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)
