Book Description
Many emerging technologies such as video conferencing, video-on-demand, and digital libraries require the efficient delivery of compressed video streams. For applications that require the delivery of compressed stored multimedia streams, the a priori knowledge available about these compressed streams can aid in the allocation of server and network resources. By using a client-side buffer, the resource requirements from the server and network can be minimized. Buffering Techniques for Delivery of Compressed Video in Video-on-Demand Systems presents a comprehensive description of buffering techniques for the delivery of compressed, prerecorded multimedia data. While these techniques can be applied to any compressed data streams, this book focusses primarily on the delivery of video streams because of the large resource requirements that they can consume. The book first describes buffering techniques for the continuous playback of stored video sources. In particular, several bandwidth smoothing (or buffering) algorithms that are provably optimal under certain conditions are presented. To provide a well-rounded discussion, the book then describes extensions that aid in the ability to provide interactive delivery of video across networks. Specifically, reservation techniques that take into account interactive functions such as fast-forward and rewind are described. In addition, extensions to the bandwidth smoothing algorithms presented in the first few chapters are described. These algorithms are designed with interactive, continuous playback of stored video in mind and are also provably optimal under certain constraints. Buffering Techniques for Delivery of Compressed Video in Video-on-Demand Systems serves as an excellent resource for multimedia systems, networking and video-on-demand designers, and may be used as a text for advanced courses on the topic.

Book Description
Interactive Video-on-Demand Systems: Resource Management and Scheduling Strategies addresses issues in scheduling and management of resources in an interactive continuous-media (e.g., audio and video) server. The book emphasizes dynamic and run-time strategies for resource scheduling and management. Such strategies provide effective tools for supporting interactivity with on-line users who require the system to be responsive in serving their requests, and whose needs and actions vary frequently over time. With an emphasis on responsiveness and transient performance, this book elaborates on dynamic strategies for managing and scheduling resources in Video-on-Demand/Multimedia systems. Unlike previous books, this volume presents an unprecedented detailed analysis of the start-up and departure of streams. It gives a comprehensive evaluation of various techniques as workloads are varied in multiple dimensions (including arrival rate, data rate and length of play). Interactive Video-on-Demand Systems: Resource Management and Scheduling Strategies collectively addresses multiple issues including QoS, throughput, responsiveness and efficiency. The solutions discussed in this volume are particularly valuable to practitioners who are building digital library, interactive multimedia and hypermedia servers. Interactive Video-on-Demand Systems: Resource Management and Scheduling Strategies is an excellent reference for researchers, practitioners and educators in the field of multimedia systems, and may be used for advanced courses on multimedia systems and Video-on-Demand servers.

Book Description
Delivering MPEG-4 Based Audio-Visual Services investigates the different aspects of end-to-end multimedia services; content creation, server and service provider, network, and the end-user terminal. Part I provides a comprehensive introduction to digital video communications, MPEG standards, and technologies, and deals with system level issues including standardization and interoperability, user interaction, and the design of a distributed video server. Part II investigates the systems in the context of object-based multimedia services and presents a design for an object-based audio-visual terminal, some of these features having been adopted by the MPEG-4 Systems specification. The book goes on to study the requirements for a file format to represent object-based audio-visual content and the design of one such format. The design introduces new concepts such as direct streaming that are essential for scalable servers. The final part of the book examines the delivery of object-based multimedia presentations and gives optimal algorithms for multiplex-scheduling of object-based audio-visual presentations, showing that the audio-visual object scheduling problem is NP-complete in the strong sense. The problem of scheduling audio-visual objects is similar to the problem of sequencing jobs on a single machine. The book compares these problems and adapts job-sequencing results to audio-visual object scheduling, and provides optimal algorithms for scheduling presentations under resource constraints, such as bandwidth (network constraints) and buffer (terminal constraints). In addition, the book presents algorithms that minimize the resources required for scheduling presentations and the auxiliary capacity required to support interactivity in object-based audio-visual presentations. Delivering MPEG-4 Based Audio-Visual Services is essential reading for researchers and practitioners in the areas of multimedia systems engineering and multimedia computing, network professionals, service providers, and all scientists and technical managers interested in the most up-to-date MPEG standards and technologies.

Multimedia Technologies and Applications for the 21st Century: Visions of World Experts presents contributions from leading researchers and experts describing their current research and their views of the future trends in the field. The book consists of thirteen chapters in five parts. These chapters tackle a number of critical issues in distributed multimedia systems and applications - from VLSI processors that support multimedia and multimedia servers, through multimedia databases and multimedia networks and communications, to merging multimedia applications. Only a few years ago multimedia seemed like a brand new research field and an emerging new industry. Today, at the edge of the 21st century, multimedia research is coming of age, and the multimedia industry has significantly grown with the total market estimated to be about $50 billion. Several years ago it was felt that the digital media revolution had just started; however, the seeds had been sown long before. Fundamental technologies, such as interactive laser disks, video games, and electronic encyclopedias were invented in the 1970s and 80s. They represented the seeds for current `hot' applications, such as digital libraries, video-on-demand, interactive television, and videoconferencing. Another aspect of the digital media revolution is the formation of a new media industry composed of computer, entertainment, communication, and consumer electronics companies. Many industry segments are currently involved in creating new products and services, positioning themselves for the 21st century. They include telephone, cable, and satellite TV companies, communication equipment companies, TV and radio broadcasters, on-line Internet service providers, cable channels, movie studios, record companies, book publishers, CD-ROM title creators, Internet tool vendors, multimedia software tools companies, computer companies, general software tools companies, computer add-on vendors, semiconductor vendors, and consumer electronics vendors. Multimedia Technologies and Applications for the 21st Century: Visions of World Experts should stimulate the curiosity of its readers and inspire new technological breakthroughs in this exciting field. It serves as a valuable reference for system designers, engineers, programmers, and managers who are involved in multimedia systems, the Internet, and their applications. This book can also be used as a textbook for advanced courses on multimedia in engineering curricula.

Book Description
Multimedia is changing the design of database and information retrieval systems. The accumulation of audio, image, and video content is of little use in these systems if the content cannot be retrieved on demand, a critical requirement that has led to the development of new technologies for the analysis and indexing of media data. In turn, these technologies seek to derive information or features from a data type that can facilitate rapid retrieval, efficient compression, and logical presentation of the data. Significant work that has not been addressed, however, is the benefits of analyzing more than one data type simultaneously. Computed Synchronization for Multimedia Applications presents a new framework for the simultaneous analysis of multiple media data objects. The primary benefit of this analysis is computed synchronization, a temporal and spatial alignment of multiple media objects. Computed Synchronization for Multimedia Applications also presents several specific applications and a general structure for the solution of computed synchronization problems. The applications demonstrate the use of this structure. Two applications in particular are described in detail: the alignment of text to speech audio, and the alignment of simultaneous English language translations of ancient texts. Many additional applications are discussed as future uses of the technology. Computed Synchronization for Multimedia Applications is useful to researchers, students, and developers seeking to apply computed synchronization in many fields. It is also suitable as a reference for a graduate-level course in multimedia data retrieval.

Book Description
Multimedia Mining: A Highway to Intelligent Multimedia Documents brings together experts in digital media content analysis, state-of-art data mining and knowledge discovery in multimedia database systems, knowledge engineers and domain experts from diverse applied disciplines. Multimedia documents are ubiquitous and often required, if not essential, in many applications today. This phenomenon has made multimedia documents widespread and extremely large. There are tools for managing and searching within these collections, but the need for tools to extract hidden useful knowledge embedded within multimedia objects is becoming pressing and central for many decision-making applications. The tools needed today are tools for discovering relationships between objects or segments within multimedia document components, such as classifying images based on their content, extracting patterns in sound, categorizing speech and music, and recognizing and tracking objects in video streams.
