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. A statistical admission control technique has also been developed based on this model. 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."

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.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Video-on-demand (VOD) is expected to become one of the most important and successful services to be offered on emerging technologies. There is not just an interest in the delivery of digital video to the home for entertainment purposes, but there are also several educational and commercial benefits from this service. However, for this service to become viable, it is important that the video servers meet the demanding data rates and real-time performance requirements imposed by video. Interval caching has been proposed as a cost-effective way of improving the throughput of a server, but all previous studies on interval caching have used simulation. With numerous parameters and their complex interplay affecting the performance of interval caching, it is infeasible to consider a full-factorial experiment with simulation. This paper presents an analytical model for interval caching on video servers. The model has been extensively validated over a range of client request, video data and server parameters. In addition, the model has been generalized to accommodate variable lengths of video data stored at the server. Using this model, the impact of different parameters has been studied on the performance of the interval caching scheme. A new caching scheme that stores every n-th frame of some popular video data is proposed to accommodate VCR operations. This scheme is shown to perform better over the two earlier proposed schemes for interval caching, particularly when the frequency of VCR operations becomes high."

This book was released on 1995 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In a video server environment, some video objects (e.g., movies) are very large and are read sequentially. Hence it is not economical to cache the entire object. However, caching random fractions of a multimedia object is not beneficial. Therefore, traditional cache management policies such as LRU are not effective. The sequential access of pages can be exploited by caching only the intervals between two successive streams on the same object, i.e., by retaining the pages brought in by a stream for reuse by a closely following stream and subsequently discarding them. In contrast to the movie-on-demand workload, an interactive workload is composed of many short video clips (e.g., shopping). Hence, concurrent access to the same video clip will be infrequent and interval caching policy will not be effective. In this paper, we propose a Generalized Interval Caching policy that caches both short video objects as well as intervals or fractions of large video objects. The efficacy of this technique for reducing disk overload and hence to increase the capacity of the video server is studied. Finally, it is shown that the proposed policy makes it cost-effective to use memory for caching video streams."

Book excerpt: 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.
