High-Rate Analysis of Symmetric L-Channel Multiple Description Coding

M-Channel Multiple Description Coding With Two-Rate Coding and Staggered Quantization

A low complexity M-channel multiple description coding scheme is developed in this paper, in which each description carries one subset of the input with a higher bit rate and the rest with a lower bit rate. The lower-rate codings in different descriptions are designed to be mutually refinable using staggered scalar quantizers. For correlated sources, a two-rate predictive coding is used in each...

Concatenated multiple description coding of frame-rate scalable video

Channel adapted scan-based multiple description video coding

In [1] we proposed a balanced Multiple Description Coding (MDC) scheme based on the Discrete Wavelet Transform (DWT). This MDC includes an efficient bit allocation procedure that dispatches the source image redundancy between different channels. The amount of redundancy is controlled according to the Bit Error Rate of the different channels. Here, we propose to extend this approach for low bit ...

Channel adapted multiple description coding scheme using wavelet transform

A challenge of image communication over unreliable channels is to achieve good compression rates and be effective in presence of channel failures. In this work we use the Multiple Description Coding (MDC) techniques, based on Wavelet Transforms, that have been shown to be powerful against channel failures. We propose a bit allocation procedure that dispatch redundancy between the different chan...

Bit-erasure channel decoding for GMM-based multiple description coding

Multiple Description Coding (MDC) is a plausible way to use the diversity of packet networks to increase the robustness of the transmission to packet losses. The redundancy that is introduced via MDC can also be used to increase the robustness of the transmission to bit-errors. This paper presents a novel decoding method for GMM (Gaussian Mixture Model)-based MDC in the presence of detected bit...
