Summary:
The cable TV network is considered as an optimal network for convergence of broadcasting and communication because it is possible to provide two-way services. Recently, the cable broadcasting network is in shortage of available frequency resources due to high quality broadcasting services, increased demand for VoD, and increased bandwidth of high-speed Internet services. This paper presents a new method for switched digital video (SDV) technology to obtain additional transmission resources in cable broadcasting networks. In the proposed SDV method, communication and broadcasting service share the same frequency band, it is possible to improve the frequency usage efficiency by providing switching of broadcasting channels without complex system construction.
