An uncoded multimedia transmission (UMT) system is one that skips quantization and entropy coding in compression and all subsequent binary operations, including channel coding and bit-to-symbol mapping of modulation. By directly transmitting non-binary symbols with amplitude modulation, the uncoded system avoids the annoying cliff effect observed in the coded transmission system. This advantage makes uncoded transmission more suited to both unicast in varying channel conditions and multicast to heterogeneous users.Particularly, in the first part of Uncoded Multimedia Transmission, we consider how to improve the efficiency of uncoded transmission and make it on par with coded transmission. We then address issues and challenges regarding how to better utilize temporal and spatial correlation of images and video in the uncoded transmission, to achieve the optimal transmission performance. Next, we investigate the resource allocation problem for uncoded transmission, including subchannel, bandwidth and power allocation. By properly allocating these resources, uncoded transmission can achieve higher efficiency and more robust performance. Subsequently, we consider the image and video delivery in MIMO broadcasting networks with diverse channel quality and varying numbers of antennas across receivers. Finally, we investigate the cases where uncoded transmission can be used in conjunction with digital transmission for a balanced efficiency and adaptation capability.This book is the very first monograph in the general area of uncoded multimedia transmission written in a self-contained format. It addresses both the fundamentals and the applications of uncoded transmission. It gives a systematic introduction to the fundamental theory and concepts in this field, and at the same time, also presents specific applications that reveal the great potential and impacts for the technologies generated from the research in this field. By concentrating several important studies and developments currently taking place in the field of uncoded transmission in a single source, this book can reduce the time and cost required to learn and improve skills and knowledge in the field.The authors have been actively working in this field for years, and this book is the final essence of their years of long research in this field. The book may be used as a collection of research notes for researchers in this field, a reference book for practitioners or engineers, as well as a textbook for a graduate advanced seminar in this field or any related fields. The references collected in this book may be used as further reading lists or references for the readers.

Following the boom in networking and data communications advancements throughout industry, this fourth edition of an ISA best-seller gives technical professionals who have little or no background in data communications the knowledge they need to understand, troubleshoot, and maintain both legacy and leading-edge systems. The text emphasizes practical functional aspects of common systems rather than design criteria. It includes a complete description of relevant terminology, standards, and protocols including EIA/TIA 232, 485, and IEEE 802. New material in this edition includes updated information on 100 MBps and 1000 MBps Ethernet, RIP and OSPF router technologies, OLE for Process Control (OPC), ActiveX, and.NET™, virtual private networks, and more. A complete glossary and index make the book especially useful as a handy desk reference. The growth and application of data communications in the industrial environment as well as emerging technologies are discussed. Contents: Historical Overview, Communication Foundations, Physical Layer and Data Link Standards, Local Area Networks, Network Operating Systems and LAN Management, Industrial Networks and Applications, Wide Area Networks.

'This book addresses key issues for businesses utilizing data communications and the increasing importance of networking technologies in business; it covers a series of technical advances in the field while highlighting their respective contributions to business or organizational goals, and centers on the issues of network-based applications, mobility, wireless networks and network security'--Provided by publisher

Technical Aspects of Data Communication, Third Edition provides information pertinent to the technical aspects of data communication. This book discusses a simple asynchronous interface implemented with a specialized integrated circuit called a UART. Organized into 28 chapters, this edition begins with an overview of the interface standards ranging from the classic EIA-232-D to the EIA-530. This text then describes modems and modem control, with material on high-speed modems and error-correcting modems. Other chapters discuss hardware and software methods. This book discusses as well digital transmission systems and the Integrated Service Digital Network (ISDN). The final chapter deals with local area networks (LANs) and shows how data communication is the key to information and resources sharing in modern networks of personal computers and work stations. This book is intended to be suitable for readers who are about to design a data communication system, are about to purchase a program data communication hardware, or are just interested in learning more about data communication.
