In the meantime, cable operators have developed their own digital services to add numerous additional channels, most of which offer video-on-demand programming. Moreover, since cable television distributes broadcast fare to 70% of the population, that industrys carriage of digital broadcast signals is crucial, and to date, US policy has not mandated that carriage. The technical standards adopted for it provided little certainty to wary manufacturers and broadcasters, digital television prices have been too high for consumers to purchase sets, set top box technology is unsettled, and consumers do not know very much about digital systems. In spite of the early promises of interactivity that digital broadcasting appeared to offer, digital television now appears to be condensed into services emphasising further consumer transactions. This updated Digital Radio Guide focuses primarily on the various digital radio systems in operation today and their associated standards.ĭigital broadcasting policy in the US has been ineffective in creating incentives, a market structure, or consumer interest sufficient to enable the broadcast industry to transition to digital signals. The issue is likely to be brought into sharper focus if and when individual countries or regional groups set timetables for phasing out existing analogue services. There are many benefits that radio broadcasters stand to gain by adopting digital technology and the current interest in digital television should help and encourage the switch from analogue to digital in radio broadcasting. It is designed to help managers, including those in developing countries, identify the technical and business forces that are driving the analogue to digital conversion process. For all broadcasters, this is leading to a new and challenging business environment in which they are searching for a clear ‘multimedia’ role.Īlthough similar changes are happening in both radio and television, this guide deals with radio. At the same time, digital developments are drawing together the broadcasting, telecommunications and computer industries in a process of convergence. Already many broadcasters have invested in digital systems for contribution and production and now the switch from analogue to digital is moving along the broadcasting chain into transmission. It will thus serve the needs of those already active in the electronics field as well as new entrants to the industry.Category: Electronics.Digital technology has steadily transformed the way in which programmes are made and distributed in recent years. It provides discussion of the preparation and characterisation of suitable polymeric materials and their current and potential applications coupled with the fundamentals of electrical, optical and photophysical properties. MalhotraISBN: Genre: ElectronicsFile Size: 85.62 MBFormat: PDFDownload: 666Read: 1044The Handbook of Polymers in Electronics has been designed to discuss the novel ways in which polymers can be used in the rapidly growing electronics industry. As we seek to answer the call for safer, more efficient, and lower-emission vehicles from regulators and consumer insistence on better performance, comfort, and entertainment, the technologies outlined in this book are vital for engineering advanced vehicles that will satisfy these criteria.Category: Technology & Engineering. Divided into five parts, the Handbook of Automotive Power Electronics and Motor Drives offers an overview of automotive power systems, discusses semiconductor devices, sensors, and other components, explains different power electronic converters, examines electric machines and associated drives, and details various advanced electrical loads as well as battery technology for automobile applications.
