This book was released on 1999 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Design of servers to meet the quality of service (QoS) requirements of interactive Video-On-Demand (VOD) systems is challenging. Recognizing the increasing use of these systems in a wide range of applications, as well as the stringent service demands expected from them, several design alternatives have been proposed to improve server throughput. A buffer management technique, called interval caching, is one such solution, which can be implemented in conjunction with other techniques to further improve performance. This mechanism exploits the temporal locality of requests to the same movie and tries to serve requests from the cache, thereby enhancing system throughput. Earlier studies have examined interval caching with only normal playback operations and have not considered various interactive VCR functionalities such as fast forward, rewind, and pause. Moreover, the complexity of the problem has confined the evaluation methodology to simulation. In this paper, we present a mathematical model for analyzing the performance of an interactive video server that uses interval caching. In particular, it captures the complex interactions of five different VCR operations and predicts the improvement in system throughput due to interval caching. Validation through simulation shows that the model is quite accurate in predicting performance over a wide range of parameters. By simply plugging in the user interactivity and system configuration parameters, one can quantify the effectiveness of interval caching. Using this model as a design tool, impact of different VCR operations on client requests and rejection probability, effect of cache size, and server design alternatives with cost constraints have been analyzed."

This book was released on 2000-10-27 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of human history we have had a communication network that is identical with the physical distribution network. In the late 19th century we established the energy network to distribute electric and thermal energy, launching the modern society. The analog communication network became popular in the middle of the 20th century. And now, at the end of the 20th century, we have global digital information networks.Along with the advancement of the communication network, the progress of the information processing technology can be classified into three historical phases. The first phase technology is physical information processing, treating physical data from the real world. This technology is often called “signal processing” and is based on the physical law of nature. The second phase is free from the physical constraints. It is logical information processing, dealing with knowledge and rules. The most important aspect of this phase is consistency. “Provable” is employed to confirm the reality of the system.Based on the advanced computer and network technology, we are entering the third phase of information processing, which is “Kansei” information processing. (”Kansei” is a Japanese word expressing some subjective ability referred to as “sensibility”, “intuition”, “affection” or “emotion”). Emotional resonance or consent is important in the pursuit of reality in this phase.Multimedia modeling to harmonize different media and systems is one of the key technologies in the third phase of information processing. It will provide a next generation framework to construct a human-centered information environment that is more comfortable and more productive.This volume is devoted to a discussion on effective modeling of multimedia information and systems for a wide range of applications. It contains 30 technical articles, all of which were selected, after vigorous peer reviews, for presentation at the International Conference on Multimedia Modeling held in Nagano, Japan, on 13-15 November 2000.
Book Synopsis Interactive Video-On-Demand Systems by : T.P. Jimmy To
Download or read book Interactive Video-On-Demand Systems written by T.P. Jimmy To and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Buffering Techniques for Delivery of Compressed Video in Video-on-Demand Systems by : Wu-Chi Feng
Download or read book Buffering Techniques for Delivery of Compressed Video in Video-on-Demand Systems written by Wu-Chi Feng and published by Springer Science & Business Media. This book was released on 2007-08-26 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
