Packet-based data communication systems su er from packet loss under high network tra c conditions. As a result, the receiver is often left with an incomplete description of the requested data. Multiple description source coding addresses the problem of minimizing the expected distortion caused by packet loss. An equivalent problem is that of source coding for data transmission over multiple ch...

In this paper, we propose a Multiple Description Coding (MDC) scheme for 3D models represented by triangular meshes. The objective of MDC is to encode a source into multiple bitstreams, called descriptions, supporting multiple quality levels of decoding. The proposed scheme is based on multiresolution geometry compression achieved by usingwavelet transform andmodified SPIHT algorithm. We obtain...

This paper presents a video transmission system using layered multiple description (coding (MDC) and multi-path transport for reliable video communications in wireless ad-hoc networks. The proposed MDC extends a quality-scalable H.264/AVC video coding algorithm to generate two independent descriptions. The two descriptions are transmitted over different paths to a receiver in order to alleviate...

Two structured multiple description (MD) vector quantization schemes with an iterative technique for designing the codebooks and partitions are proposed. The schemes are derived from the recent theoretical work by Chen et al. In the first scheme, the central decoder is formed by the weighted sum of the side codebooks, whereas the second scheme employs the optimum central decoder. The objective ...

Multiple description coding (MDC) is an error resilient source coding scheme that creates multiple descriptions of the source with the aim of providing an acceptable reconstruction quality when only one description is received, and improved quality as more descriptions become available. Recently, we developed a matching pursuit multiple description video coder (MP-MDVC) based on a three loop st...

In this paper we propose a Multiple Description Image Coding(MDIC) scheme to generate two compressed and balanced rates descriptions in the wavelet domain (Daubechies biorthogonal (9, 7) wavelet) using pairwise correlating transform optimal and application method for Generalized Multiple Description Coding (GMDC) to image coding in the wavelet domain. The GMDC produces statistically correlated ...
