A Multi-Channel Multimedia Content Distribution Strategy using Multiple Description Coding

A Method to Reduce Effects of Packet Loss in Video Streaming Using Multiple Description Coding

Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...

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...

Multiple Viewpoints: A Strategy for Searching Multimedia Content

Multiple viewpoint systems are an approach to information retrieval that takes advantage of having more than one source of judgments on a body of information. Multiple viewpoints can improve retrieval effectiveness over the typical single-viewpoint approach, especially in cases when there is vocabulary mismatch between the user formulating queries and the information retrieval system. We are pa...

An Improved Multiple Description Coding Strategy Based on Path Diversity

In this paper, a source coding technique exploiting packet path diversity is presented, which combines the individual benefits of MDC (multiple description coding) and LC (layer coding) for video transmission over wireless networks. Performance comparisons between LC and MDC are discussed at the beginning of this paper. Their advantages and disadvantages are concluded. An improved coding techni...
