Abstract: A timing decision apparatus includes: an adaptability decision unit configured to decide a correspondence between a feature quantity of media as encoded data capable of being replayed and an adaptability showing a degree of adaptation for providing a specific service; an adaptability storage unit configured to store the correspondence; and a timing decision unit configured to decide timing of providing the specific service in response to a value of the adaptability stored in the adaptability storage unit.

Abstract: A notification-purpose user state managing apparatus, a notification controlling apparatus, an information notification apparatus, an information notification system and an information notification method capable of reducing an unpleasant feeling and a burden and encouraging a user to recognize information are provided. The information notification system includes a notification-purpose user state managing apparatus including user's internal state assuming means for assuming a user's internal state based on an observable state element and user's notification utility assuming means for assuming utility to a user receiving information when information is notified based on the user's internal state; and a notification controlling apparatus including notification executing means for determining whether or not information is notified based on the utility and notifying information based on the determination.

Abstract: The suspended service recovery system is configured with a suspend-state analyzing module 14 to analyze a suspend-state and to extract required data to recover the suspend-state if a service being provided via a communication network 4 is suspended, a suspend-state representation module 12 to convert a result of the analysis to state-description data D2 according to a prescribed format, a storing device 3 to store the state-description data D2, a memory device 21 to memorize a recovery table which correlates each item of the state-description data D2 with a data type that can be processed on a client terminal 2, a state-description transforming module 24 to transform the state-description data D2 retrieved from the storing device 3 based on the recovery table, and a recovery-state generating module 25 to recover the suspended service.
