发明名称 INFORMATION DISTRIBUTION SYSTEM, INFORMATION DISTRIBUTION METHOD, NODE DEVICE, KEY DATA MANAGEMENT DEVICE, AND RECORDING MEDIUM
摘要 Provided is an information distribution system capable of acquiring the program information having failed to be recorded, reliably and by a simple operation, without burdening a server device with heavy loads. The system includes a plurality of node devices capable of communicating with each other through a network. The node device having received and stored the program information broadcast from a broadcasting station creates the identification information corresponding to the program code intrinsic to the program information stored, and sends a message to register the node device having stored the program information, on the basis of the identification information, to the node device managing that identification information. The node device desiring to acquire the program information creates the identification information corresponding to the program code intrinsic to the program information desired to acquire, and sends a message requesting the program information, on the basis of the identification information, to the node device having managed the identification information, thereby to acquire that program information from the node device storing that program information.
