Features: This book systematically introduces various widely-used cable TV encryption and descrambling systems in the world today, including advanced CATV encryption and descrambling systems from Western countries such as the United States, Japan, France, the United Kingdom, Canada, etc. It also covers systems introduced or jointly developed in China by research institutions and factories. The content is little-known yet highly practical. The book thoroughly details practical circuits, used ICs, signal waveforms, performance indicators, and testing methods. The latter chapters introduce the connection methods between on-board converters and visual descrambling boards, providing a "guide" for manufacturers.
