Storage-type broadcast system, transmitter and receiver

A transmitter of a storage-based digital broadcast system wherein contents transmitted from a sending side are stored on a receiving side, separated from said sending side, then reproduced, characterized in that said transmitter comprises

• service structure information generating means for generating service structure information representing a relational structure between services provided by contents providers,
• reference information generating means for generating reference information for associating the contents with the service described in said service structure information,
• service information adding means for adding said reference information to service information, and
• multiplexing/transmission means for multiplexing service information containing said reference information and said service structure information into contents and transmitting the resulting data.

A receiver of a storage-based digital broadcast system wherein contents transmitted from a sending side are stored on a receiving side, separated from said sending side, then reproduced, characterized in that said receiver comprises

• receiving/demultiplexing means for demultiplexing contents, service structure information describing the relational structure between services provided by contents providers and service information containing reference information associating contents with the service described in said service structure information from received signals,
• contents storage means for storing demultiplexed contents,
• service structure storage means for storing demultiplexed service structure information,
• service information storage means for storing said demultiplexed service information, and
• service management means for managing storage of said contents by using service structure information and reference information.
