In a storage-based digital broadcast system wherein contents transmitted from a sending side are stored on a receiving side then reproduced, the sending side transmits service structure information for describing relational structure between services provided by contents providers and reference information for associating the contents with the service structure information in advance, and the receiving side receives and stores service structure information and reference information and uses the received service structure information and reference information to manage storage of contents. It is possible to control contents per service based on service structure information and information that can be reorganized from reference information.
