Abstract
Digital Broadcasting Services get abroad from satellite services to terrestrial services and cable services. As broadcasting services become digital from analog, diverse services such as multi-channel, high quality, time-shift function and so on can be possible. It also generates new digital businesses. The Conditional Access System(CAS) is a technology for providing prevention of illegal access to digital contents. It was applied to digital satellite services at Europe and America from the beginning of 90's. In 2002, a domestic digital satellite service provider adopt a CAS system to their broadcasting services. DRM technologies protect intellectual properties and digital rights of digital contents. This paper suggests a design method to construct a CAS system with DRM which can be applied to a CAS for a small digital broadcasting service.
