Joint Sourcechannel Decoding: A Crosslayer Perspective With Applications In Video Broadcasting (Eurasip And Academic Press Ser

Treats joint source and channel decoding in an integrated wayGives a clear description of the problems in the field together with the mathematical tools for their solutionContains many detailed examples useful for practical applications of the theory to video broadcasting over mobile and wireless networksTraditionally, crosslayer and joint sourcechannel coding were seen as incompatible with classically structured networks but recent advances in theory changed this situation. Joint sourcechannel decoding is now seen as a viable alternative to separate decoding of source and channel codes, if the protocol layers are taken into account. A joint source/protocol/channel approach is thus addressed in this book: all levels of the protocol stack are considered, showing how the information in each layer influences the others.This book provides the tools to show how crosslayer and joint sourcechannel coding and decoding are now compatible with presentday mobile and wireless networks, with a particular application to the key area of video transmission to mobiles. Typical applications are broadcasting, or pointtopoint delivery of multimedia contents, which are very timely in the context of the current development of mobile services such as audio (MPEG4 AAC) or video (H263, H264) transmission using recent wireless transmission standards (DVHH, DVBSH, WiMAX, LTE).This crossdisciplinary book is ideal for graduate students, researchers, and more generally professionals working either in signal processing for communications or in networking applications, interested in reliable multimedia transmission. This book is also of interest to people involved in crosslayer optimization of mobile networks. Its content may provide them with other points of view on their optimization problem, enlarging the set of tools which they could use.Pierre Duhamel is director of research at CNRS/ LSS and has previously held research positions at ThomsonCSF, CNET, and ENST, where he was head of the Signal and Image Processing Department.
