EURASIP Journal on Image and Video Processing, 2007 We present a new multiple-description coding (MDC) method for scalable video, designed for transmission over error-prone networks. We employ a redundant motion-compensated scheme derived from the Haar multiresolution analysis, in order to build ...

Multiple-Description Coding by Dithered Delta-Sigma Quantization [PDF]
, 2009 We address the connection between the multiple-description (MD) problem and Delta-Sigma quantization. The inherent redundancy due to oversampling in Delta-Sigma quantization, and the simple linear-additive noise model resulting from dithered lattice ...

Multiple Description Coding Based Network Coding
International Journal of Computer Applications, 2010 This paper presents a proposal for transmitting images using Multiple Description Coding (MDC) techniques over multiple links in a mesh network, while using network coding technique to add protection paths. In pure MDC, the losses of one or two of the multiple descriptions degrade the received image quality.

Error concealment for slice group based multiple description video coding [PDF]
, 2005 This paper develops error concealment methods for multiple description video coding (MDC) in order to adapt to error prone packet networks. The three-loop slice group MDC approach of D. Wang et al. (2005) is used.

Multiple description coding of animated meshes
Signal Processing: Image Communication, 2010 In this paper, we propose three novel multiple description coding (MDC) methods for reliable transmission of compressed animated meshes represented by series of 3D static meshes with same connectivity. The proposed methods trade off reconstruction quality for error resilience to provide the best expected reconstruction of 3D mesh sequence at the ...

Embedded Multiple Description Coding of Video
IEEE Transactions on Image Processing, 2006 Real-time delivery of video over best-effort error-prone packet networks requires scalable erasure-resilient compression systems in order to 1) meet the users' requirements in terms of quality, resolution, and frame-rate; 2) dynamically adapt the rate to the available channel capacity; and 3) provide robustness to data losses, as retransmission is ...
