The HDTV workshops were established with the aim of aiding definition and fostering the introduction of HDTV. Their fundamental principle is the separation of the standardisation process from the technological development, with the workshops concentrating mainly on the latter. Over the past few years important steps towards actual implementation of HDTV have been made in the major countries. The aim of this workshop was to ask some key people in the HDTV world to express their views about the forms in which an HDTV or Advanced Television Service could be introduced or has actually been started, with the goal of identifying which areas of research are currently in most need of attention. HDTV is now considered to be a strategic piece of applied research in virtually all countries of the world and in many environments there is mounting pressure to start up service and equipment manufacturing. The papers presented in this volume constitute a key contribution to the establishment of this giant step towards a fully fledged information society. Due to the extensive length of the contents, only the number of papers presented per session is listed below.

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.

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".

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.

The technological background established in these early chapters - especially in the production and processing of television images - vividly illuminates the development of the sophisticated image processing employed in contemporary radar, space exploration, and medical radiological imaging. Continuing this integrated approach, the author links the fundamentals of analog telephony to the development of modern digital signal processing in telecommunications and networking. A detailed account of microprocessor technology further integrates the overall picture of the field of contemporary signal and image processing. Logically, the discussion is extended to the aspects of signal processing involved in artificial intelligence and neural networks.

Multirate Switched-Capacitor Circuits for 2-D Signal Processing introduces the concepts of analog multirate signal processing for the efficient implementation of two-dimensional (2-D) filtering in integrated circuit form, particularly from the viewpoints of silicon area and power dissipation. New 2-D switched-capacitor (SC) networks and design techniques are presented, both with finite impulse response (FIR) and infinite impulse response (IIR) with separable denominator polynomial, which offer simpler and more systematic synthesis procedures than currently available design techniques for 2-D analog filters. Since they are in the discrete-time domain, the book can be also referred to the digital multirate signal processing. A 2-D SC image processor that realizes both (2 x 2)nd-order Butterworth lowpass and highpass filtering functions for video image signals was realized as a prototype integrated circuit implemented in 1.0-mum CMOS technology. The experimental characterization of this prototype chip demonstrated the feasibility of real-time analog multirate 2-D image processing with equivalent 8-bits accuracy, using only 2.5 x 3.0 mm2 of silicon area and dissipating as little as 85 mW at 5V supply and 18 MHz sampling rate. This indicates that for moderate accuracy and low to moderate complexity of the filtering function, a fully multirate analog implementation has a potential to achieve a more competitive implementation than an alternative digital VLSI implementation. However, for high accuracy and/or higher processing complexity, not only the relative overhead cost of the front-end and back-end converters will diminish but also the implementation of the processing core in digital VLSI will benefit more of technology scaling to achieve higher density of integration. Multirate Switched-Capacitor Circuits for 2-D Signal Processing is essential reading for practicing analog design engineers and researchers in the field. It is also suitable as a text for an advanced course on the subject.

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.
