EFFICIENT MOBILE VIDEO TRANSMISSION BASED ON A JOINT CODING SCHEME
Journal of ICT, 2017 In this paper, we propose a joint coding design which uses the Symbol Forward Error Correction (S-FEC) at the application layer. The purpose of this work is on one hand to minimize the Packet Loss Rate (PLR) and, on the other hand to maximize the visual ...

Rateless Polar-Spinal Coding Scheme With Enhanced Information Unequal Error Protection
IEEE Access, 2019 In this paper, a rateless coding scheme with enhanced unequal error protection (UEP) property is proposed by concatenating the systematic polar code (SPC) and spinal code, where SPC is used as the outer code and spinal code is the inner code.

Adaptive UEP and Packet Size Assignment for Scalable Video Transmission over Burst-Error Channels
EURASIP Journal on Advances in Signal Processing, 2006 This work proposes an adaptive unequal error protection (UEP) and packet size assignment scheme for scalable video transmission over a burst-error channel. An analytic model is developed to evaluate the impact of channel bit error rate on the quality of

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.

Canonical convolutional encoders for unequal error protection
, 2012 [[abstract]]In this paper, canonical convolutional encoders are studied for unequal error protection (UEP) from an algebraic theoretical viewpoint. We show that for any convolutional code there exists at least a canonical generator matrix which has the ...

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)
