This book deals with the problem of joint source-channel video transmission, i.e., the joint optimal allocation of resources at the application layer and the other network layers, such as data rate adaptation, channel coding, power adaptation in wireless networks, quality of service (QoS) support from the network, and packet scheduling, for efficient video transmission. Real-time video communication applications, such as videoconferencing, video telephony, and on-demand video streaming, have gained increased popularity. However, a key problem in video transmission over the existing Internet and wireless networks is the incompatibility between the nature of the network conditions and the QoS requirements (in terms, for example, of bandwidth, delay, and packet loss) of real-time video applications. To deal with this incompatibility, a natural approach is to adapt the end-system to the network. The joint source-channel coding approach aims to efficiently perform content-aware cross-layer resource allocation, thus increasing the communication efficiency of multiple network layers. Our purpose in this book is to review the basic elements of the state-of-the-art approaches toward joint source-channel video transmission for wired and wireless systems. In this book, we present a general resource-distortion optimization framework, which is used throughout the book to guide our discussions on various techniques of joint source-channel video transmission. In this framework, network resources from multiple layers are assigned to each video packet according to its level of importance. It provides not only an optimization benchmark against which the performance of other sub-optimal systems can be evaluated, but also a useful tool for assessing the effectiveness of different error control components in practical system design. This book is therefore written to be accessible to researchers, expert industrial R&D engineers, and university students who are interested in the cutting edge technologies in joint source-channel video transmission.

Treats joint source and channel decoding in an integrated way Gives a clear description of the problems in the field together with the mathematical tools for their solution Contains many detailed examples useful for practical applications of the theory to video broadcasting over mobile and wireless networks Traditionally, cross-layer and joint source-channel coding were seen as incompatible with classically structured networks but recent advances in theory changed this situation. Joint source-channel 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 cross-layer and joint source-channel coding and decoding are now compatible with present-day mobile and wireless networks, with a particular application to the key area of video transmission to mobiles. Typical applications are broadcasting, or point-to-point 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 (DVH-H, DVB-SH, WiMAX, LTE). This cross-disciplinary 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 cross-layer 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 Thomson-CSF, CNET, and ENST, where he was head of the Signal and Image Processing Department. He has served as chairman of the DSP committee and associate Editor of the IEEE Transactions on Signal Processing and Signal Processing Letters, as well as acting as a co-chair at MMSP and ICASSP conferences.

Successful video communication over wireless channels is one of the most technically challenging problems in multimedia communications. The inherent vulnerability of compressed video to transmission errors and the time varying and fading environments of the wireless channel combined with network and application constrains presents some major technological issues that needs to be addressed. To improve the error resiliency and efficiency of transmitting video over wireless channels. Several techniques are developed that contribute to better utilize the error resilient features available in H.264 and propose enhancements to the frame layer rate control. Firstly, new techniques on how to use explicit Flexible Macroblock Ordering (FMO) more effectively in wireless video ransmission by using combined spatial and temporal indicators of macroblock (MB) importance to generate slice group maps for H.264. Secondly, an improved sorting algorithm that classifies macroblocks into different slice groups for FMO in H.264 that further improves the use of explicit FMO. Thirdly, enhancements to the H.264 frame layer rate control is proposed, that takes into consideration the effects of using FMO for video transmission, to better manage bit allocation and improve coding efficiency. We propose a new header bits model, an enhanced frame complexity measure, a bit allocation and a quantization parameter (QP) adjustment scheme. Lastly, a framework for adaptive FMO selection scheme based on feedback information is presented. In summary, in this dissertation we propose the framework of using explicit FMO, rate control and feedback information for wireless video transmission. Experimental results show that the proposed techniques are effective in improving the video quality especially for complex video sequences and at low-bit rates.
