Book Description
Many video applications, such as mobile TV, videoconferencing, and on-demand video streaming, have gained increased popularity. However, a key problem of video transmission over the existing wireless networks is the mismatch between the nature of the wireless system conditions and the constant quality requirements, such as bandwidth, and packet loss for video applications. Cross-layer design is a natural approach to deal with the incompatibility problem. This approach aims to efficiently perform cross-layer resource allocation (such as bandwidth and transmission power) by increasing the communication efficiency of multiple network layers. In this dissertation, we consider the problem of scalable video transmission over next-generation multi-antenna multi-carrier wireless systems. We propose different resource allocation optimization strategies between application layer and physical layer of the end-to-end system. The proposed framework is general and flexible. Scalability in the video bitstream is exploited by partitioning and producing multiple layers which cater to wide heterogeneous networks. The scalable extension of H.264/AVC, popularly known as scalable video codec (SVC) that provides a combined temporal, quality and spatial scalability is used in this work for transmission over varied networks. We first develop a low-delay low-complexity method for the estimation of the decoded video distortion at the encoder and propose different error concealment schemes. We consider a bandwidth-constrained video transmission over multiple-input multiple-output (MIMO) system with orthogonal space-time block codes (O-STBC). The O-STBC provides spatial diversity and guarantees independent transmission of different symbols within the block code. The hierarchical nature of SVC and orthogonal structure of O-STBC are exploited to design the cross-layer bandwidth optimization strategy. It involves optimally selecting the application layer and physical parameters based on the estimated distortion. The results exemplify the advantages of keeping various parameters under optimization versus allocating them at a fixed value. We consider the transmission of scalable video over MIMO systems using OFDM technique. We propose another modification to the distortion estimation algorithm based on the importance of temporal and quality scalability. We compare the performance under optimal bandwidth allocation framework. Then, we propose transmission power allocation strategies based on using unequal number of OFDM sub-carriers for different layers of scalable video.

Book Description
Multimedia over IP and Wireless Networks is an indispensable guide for professionals or researchers working in areas such as networking, communications, data compression, multimedia processing, streaming architectures, and computer graphics. Beginning with a concise overview of the fundamental principles and challenges of multimedia communication and networking, this book then branches off organically to tackle compression and networking next before moving on to systems, wireless multimedia and more advanced topics. The Compression section advises on the best means and methodology to ensure multimedia signal (images, text, audio and data) integrity for transmissions on wireless and wired systems. The Networking section addresses channel protection and performance. In the Systems section, the focus is on streaming media on demand, live broadcast and video and voice's role in real-time communication. Wireless multimedia transmission and Quality of Service issues are discussed in the Wireless Multimedia section. An Advanced Topics section concludes the book with an assortment of topics including Peer-to-Peer multimedia communication and multipath networks. Up-to-date coverage of existing standards for multimedia networking Synergistic tutorial approach reinforces knowledge gained in previous chapters Balanced treatment of audio and video with coverage of end-to-end systems

Book Description
Welcome to the second IEEE Pacific Rim Conference on Multimedia (IEEE PCM 2001) held in Zhongguanchun, Beijing, China, October 22 24, 2001. Building upon the success of the inaugural IEEE PCM 2000 in Sydney in December 2000, the second PCM again brought together the researchers, developers, practitioners, and educators of multimedia in the Pacific area. Theoretical breakthroughs and practical systems were presented at this conference, thanks to the sponsorship by the IEEE Circuit and Systems Society, IEEE Signal Processing Society, China Computer Foundation, China Society of Image and Graphics, National Natural Science Foundation of China, Tsinghua University, and Microsoft Research, China. IEEE PCM 2001 featured a comprehensive program including keynote talks, regular paper presentations, posters, demos, and special sessions. We received 244 papers and accepted only 104 of them as regular papers, and 53 as poster papers. Our special session chairs, Shin'ichi Satoh and Mohan Kankanhalli, organized 6 special sessions. We acknowledge the great contribution from our program committee members and paper reviewers who spent many hours reviewing submitted papers and providing valuable comments for the authors. The conference would not have been successful without the help of so many people. We greatly appreciated the support of our honorary chairs: Prof. Sun Yuan Kung of Princeton University, Dr. Ya Qin Zhang of Microsoft Research China, and Prof.
