Abstract: An information processing apparatus refers to management information in which an identifier of each of a plurality of dispersed file fragments obtained by dividing an original file and distributedly stored in a plurality of storage devices and a path indicative of a storage location of each of the plurality of dispersed file fragments are recorded in association with an identifier of the original file. Next, the information processing apparatus displays the identifier of the original file. Next, when a selection operation is performed on the identifier of the original file, the information processing apparatus acquires the plurality of dispersed file fragments corresponding to the original file on the basis of the identifier of each of the plurality of dispersed file fragments and the path. Furthermore, the information processing apparatus combines the plurality of dispersed file fragments to generate the original file.

Abstract: The display device includes a priority calculation unit which calculates the priority so that the priority of category to which a program viewed by the user belongs is increased and the priority of the other category is decreased, a program feature information storage unit which stores correspondence information between the category and a feature word, a program feature extraction unit which extracts the feature word for each program from program information, a display program control unit which selects the program belonging to the category in which the priority is the highest from the programs being broadcast, and a program display processing unit which displays the selected program.

Abstract: A display device collects pieces of EPG information, stores the program information of a viewed program as a piece of viewing history information, counts the number of occurrences of each of categories in viewing history information and calculates the priority of each category based on the number of occurrences, and stores it in a priority information storage unit. Then, the display device selects one or more programs in a category having the highest priority based on the pieces of program information of programs currently being broadcasted and priority information at power-on, displays the selected programs in thumbnail screens on a display and, if one of the thumbnail screens is selected as an object to be viewed, switches the display screen for the program to a normal screen.
