How digital television works, and how to get the most out of it. This book is basic enough so that no previous background is needed. The most detailed chapters, however, provide enough detail to satisfy even a technically sophisticated audience. In accessible language, it describes how to upgrade an existing home entertainment system to digital television, how satellite and cable TV works, and it describes the core technologies involved. It also looks closely at the DVB and ATSC video protocols and how they are used in satellite, cable and over-the-air TV broadcasting. It even provides enough detail for the computer hobbyist or home theater specialist to get involved in building or modifying a digital video system of his or her own.
