Preface The boundaries between the IT world, Internet systems and broadcast television technologies have blurred. The result of this blurring effect has been the development of a new computing paradigm that is focussed on the home entertainment market. The evolution of this new paradigm in tandem with a demand for new interactive TV applications has created the need for a special interface or gateway device that can be used to pass digital content between high-speed broadband networks and millions of homes across the world. A low cost consumer electronics device called a digital set-top box is poised and ready to take center stage in this new digital world we are about to enter. Most industry analysts agree that in the near future, people will choose a digital set-top box to access a myriad of new services that are available from this new paradigm. Consumers can use their digital set-top boxes to sit down and enjoy watching cinema style pictures with CD quality sound. Advanced versions of these devices have intuitive and easy to use interfaces that allow people to access instant video on demand, e-commerce services and a range of entertainment services that are being dreamed up by the entrepreneurs of the future. The first couple of chapters in this book will present you with a description of how the set-top business has evolved over the past couple of years. Digital set-top boxes nowadays contain a number of components that are very similar to a desktop PC. So in chapter two we guide you through the terms and concepts that relate to each of these components. The proliferation of digital technologies has sparked off the development of a number of software and hardware technologies. This book explores the various industry initiatives and standard bodies that are working on defining open set-top box technologies around the world. Many companies, including Microsoft, PowerTV, PlanetWeb, OpenTV, Liberate Technologies, Canal+ and Sun Microsystems are vying to gain an early lead in defining the features of digital set-top boxes, as well as the lucrative interactive TV services that go along with them. This book presents you with a detailed description of the set-top products that are available from these companies. Additionally we help you understand the confusing array of computer technologies that has become synonymous with the world of digital set-top boxesÑmiddleware, ECMAScript, JavaTV, HTML, TVPAK, JavaScript, DirectX, Windows 2000, XML and much more. The proliferation of these new technologies into the homes of the future will serve as a springboard to new and exciting opportunities for software developers who want to move away from the world of PC software development to the lucrative world of developing enhanced TV applications. The middle of this book covers the methodologies used by existing developers and presents a brief overview of the development kits that are available for the various set-top software platforms. In addition to the software development community, interactive TV is opening up new markets for the enormous pool of talented people involved in creating content. In chapter twelve of this book you will gain an insight into mechanisms that are used to author and deliver content that has been optimized for the TV world. People often donÕt realize that behind the simple end user interface they see on their television set, there is a complex network architecture that is required to support the various applications. This book goes behind the scenes and looks at the servers and technologies that are needed to support a range of broadband Internet, Intranet, and TV-centric applications. Towards the end of the book we look at the security mechanisms and smart card technologies used by network service providers to control access to digital TV pay services. Our final chapter looks ahead to the digital set-top box becoming a telecommunications hub for the homes of the future. The book concludes with a snapshot of the types of technologies that are currently under development for the next generation of advanced digital set-top boxesÑhome networking, advanced 3D, voice activation, and personalization technologies.
