A color time-varying image can be described as a three-dimensional vector (representing the colors in an appropriate color space) defined on a three-dimensional spatiotemporal space. In conventional analog television a one-dimensional signal suitable for transmission over a communication channel is obtained by sampling the scene in the vertical and tem poral directions and by frequency-multiplexing the luminance and chrominance informa tion. In digital processing and transmission systems, sampling is applied in the horizontal direction, too, on a signal which has been already scanned in the vertical and temporal directions or directly in three dimensions when using some solid-state sensor. As a conse quence, in recent years it has been considered quite natural to assess the potential advan tages arising from an entire multidimensional approach to the processing of video signals. As a simple but significant example, a composite color video signal, such as the conven tional PAL or NTSC signal, possesses a three-dimensional spectrum which, by using suitable three-dimensional filters, permits horizontal sampling at a rate which is less than that re quired for correctly sampling the equivalent one-dimensional signal. More recently it has been widely recognized that the improvement of the picture quality in current and advanced television systems requires well-chosen signal processing algorithms which are multidimen sional in nature within the demanding constraints of a real-time implementation.

In the late 1980s and 1990s, the advanced industrial countries considered replacing the existing analogue television infrastructure with a new digital one. A key common feature to the debates over digital TV (DTV) in the United States, Western Europe and Japan was the eventual victory of the ideas of digitalism (the superiority of everything digital over everything analogue) and of digital convergence (the merging of computing, telecommunications and broadcasting infrastructures made possible by digitalization) in public debates over standards. Jeffrey Hart's book shows how nationalism and regionalism combined with digitalism to produce three different and incompatible DTV standards in the three regions, an outcome which has led to missed opportunities in developing the new technologies. Hart's book contributes to our understanding of relations between business and government, and of competition between the world's great economic powers.

An image or video sequence is a series of two-dimensional (2-D) images sequen tially ordered in time. Image sequences can be acquired, for instance, by video, motion picture, X-ray, or acoustic cameras, or they can be synthetically gen erated by sequentially ordering 2-D still images as in computer graphics and animation. The use of image sequences in areas such as entertainment, visual communications, multimedia, education, medicine, surveillance, remote control, and scientific research is constantly growing as the use of television and video systems are becoming more and more common. The boosted interest in digital video for both consumer and professional products, along with the availability of fast processors and memory at reasonable costs, has been a major driving force behind this growth. Before we elaborate on the two major terms that appear in the title of this book, namely motion analysis and image sequence processing, we like to place them in their proper contexts within the range of possible operations that involve image sequences. In this book, we choose to classify these operations into three major categories, namely (i) image sequence processing, (ii) image sequence analysis, and (iii) visualization. The interrelationship among these three categories is pictorially described in Figure 1 below in the form of an "image sequence triangle".

In a world at the eve of digital television by satellite and cable, this publication provides a state-of-the-art exploration of the latest developments in HDTV technology. It highlights the technologies needed to launch HDTV from demonstration and trial status to that of a complete product and service. It also contributes towards the provision of the knowledge base required for the planning and management of the spectrum across the continents. Papers are sourced from a wide range of international experts in the field, including those from Canada, where, according to L. Chiariglione, ... An incredibly bold gamble, the progressive introduction of HDTV service on the [Canadian] terrestrial distribution network, additional to the existing TV service, has been proven to work and steps have been taken towards the full technical specification of the complete system. This publication aims to have the dream of interactive television take a leap forward into reality.

This is the first comprehensive treatment of the theoretical aspects of the discrete cosine transform (DCT), which is being recommended by various standards organizations, such as the CCITT, ISO etc., as the primary compression tool in digital image coding. The main purpose of the book is to provide a complete source for the user of this signal processing tool, where both the basics and the applications are detailed. An extensive bibliography covers both the theory and applications of the DCT. The novice will find the book useful in its self-contained treatment of the theory of the DCT, the detailed description of various algorithms supported by computer programs and the range of possible applications, including codecs used for teleconferencing, videophone, progressive image transmission, and broadcast TV. The more advanced user will appreciate the extensive references. Tables describing ASIC VLSI chips for implementing DCT, and motion estimation and details on image compression boards are also provided.
