Abstract:
In an information processing system, a speculative DL content information acceptor 324 accepts identification information of content selected by a server. A list generator generates a speculative DL list of the accepted content identification information. Based on the speculative DL list, a DL processor sets the time of start of download of content data and downloads the content data at the set time.
Abstract:
In an information processing system, a speculative DL content information acceptor 324 accepts identification information of content selected by a server. A list generator 352 generates a speculative DL list 388 of the accepted content identification information. Based on the speculative DL list 388, a DL processor 372 sets the time of start of download of content data and downloads the content data at the set time.

Abstract:
An RFID aggregate storage stores a radio-frequency ID aggregate structure. The RFID aggregate structure is an aggregated data structure of a plurality of RFIDs, in which each RFID is associated with a location and time read out from a RFID tag, and RFID related information, hierarchically constructed by classifying RFIDs based on the readout location and further by classifying them based on the readout time. A proximity evaluator evaluates the proximity between the first user's RF ID aggregate and the second user's RFID aggregate. A user classifier classifies the first user and the second user in one group when the proximity is smaller than a predetermined threshold value.
