Joint Source-Channel Video Transmission by Fan Zhai

Joint Source-Channel Video Transmission by Fan Zhai

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.

Peter A. Petri, visiting fellow at the Peterson Institute for International Economics, is the Carl J. Shapiro Professor of International Finance in the International Business School of Brandeis University and a senior fellow of the East-West Center. From 1994 to 2006, he served as the founding dean of the International Business School. He has held appointments as visiting scholar or professor at the Organization for Economic Cooperation and Development (OECD), Keio University, and Fudan University, and as Fulbright Research Scholar and Brookings Policy Fellow. He has consulted for the Asian Development Bank, the Asian Development Bank Institute, the World Bank, the OECD, the United Nations, and the governments of the United States and other countries. He is active in US-Asia affairs and is a member of the Board of the US Asia Pacific Council, the International Advisory Group of the Pacific Economic Cooperation Council (PECC) Trade Policy Forum, and the International Steering Committee of the Pacific Trade and Development Conference Series (PAFTAD).

Michael G. Plummer is the Eni Professor of International Economics at Johns Hopkins University, SAIS Bologna. He is also editor-in-chief of the Journal of Asian Economics and (nonresident) senior fellow at the East-West Center. He was head of the Development Division of the Organization for Economic Cooperation and Development (2010-12), the associate professor of economics at Brandeis University, and director of its MA programs at the International Business School. He was also a Fulbright Chair in Economics; Pew Fellow in International Affairs, Harvard University; research professor at Kobe University; and visiting fellow at ISEAS, the University of Auckland, and Doshisha University. Plummer has worked on numerous projects for international organizations, development and other government agencies, and regional development banks, including the Asian Development Bank (ADB), the Association for Southeast Nations (ASEAN) Secretariat, and the ADB Institute.

Fan Zhai is managing director and head of the asset allocation and strategy research department of the China Investment Corporation (CIC). He is responsible for overall asset allocation strategy and portfolio management of CIC's overseas investment. He also oversees macroeconomic research and market analysis to support strategic asset allocation and tactical investment views. Before he joined CIC in November 2009, he was research fellow at the Asian Development Bank in Manila. He has also worked at the Ministry of Finance and the Development research Center of the State Council in China.
