Broadband Cable TV Access Networks: From Technologies to Applicationsby Shlomo Ovadia
Synopses & Reviews
Next-generation CATV systems: architecture, protocols, technologies, and applications.
Broadband cable TV networks are undergoing a massive transformation, from simply broadcasting analog TV channels to providing sophisticated, two-way interactive services such as high-speed Internet access and video-on-demand. Now, one of the field's leading experts reviews the technologies, protocols, applications associated with the CATV revolution, and previews the migration path from today's two-way hybrid fiber/coax networks to the awesome capacities of tomorrow's DWDM fiber networks. Coverage includes:
Ovadia offers in-depth analyses of single and multiple-wavelength fiber-optics transmission impairments over HFC and DWDM networks, and presents the emerging two-way DWDM network architecture. Finally, he discusses the DOCSIS cable modem protocol, as well as key set-top box's applications such as electronic program guides (EPGs), video-on-demand (VOD), Internet-based applications such as e-mail, and e-commerce.
Whether you're an engineer, scientist, cable professional, manager, or investor, if you want to understand where cable is headed, you need Cable TV Access Networks: From Technologies to Applications.
Book News Annotation:
Reviews the technologies, protocols, and applications associated with the cable TV (CATV) revolution, and previews the migration path from today's two-way hybrid fiber/coax (HFC) networks to the potential of DWDM fiber networks. Introduces key fiber-optics transmission technologies, and discusses hardware architecture of end-user home terminals. Analyzes single and multiple-wavelength fiber-optics transmission impairments over HFC and DWDM networks, and discusses transmission protocol, software architecture, and applications for end-user home terminals. Of interest to engineers, scientists, and cable professionals, managers, and investors. Ovadia works at Intel. He is a senior member of IEEE, and has written some 60 technical publications and conference presentations.
