This chapter focuses on digital cable TV networks as a convergent network with telecommunications networks and the Internet that provides broadcasting TV and radio, telecommunications services, and IP-based publishing and e-commerce. The chapter first traces the technological evolution of cable TV, highlighting recent developments in digitalization and convergence. The transformation of cable TV networks from channel operators to unified platforms is discussed. In doing so, the key terms and concepts in cable TV technology are introduced. The technological, political, regulatory, and economic forces behind the convergence are also identified. Furthermore, this chapter examines the value chain and collaborative opportunities among the participants in the digital cable TV revolution. User-centered business models of managing digital cable TV networks are proposed.

A new structure of carrier recovery loop for high-order QAM is proposed in this paper, and applied in digital cable TV monitoring system. The structure operates in two modes with variable loop bandwidths, has the advantage of increasing convergence speed and minimizing the lock error, meanwhile, optimises the phase detection mode for the weighted DD algorithm to attain the fast recovery. Simulation results show that the algorithm is practicable and effective, and the carrier loop can capture up to 40% frequency offset of the symbol rate quickly and accurately.
