Abstract: A remote control system includes a main body apparatus and a remote controller. A motion sensor included in the remote controller detects an amount of change in posture of the remote controller. A user interface creator included in the main body apparatus creates a user interface image including a pointer. The user interface creator: determines virtual coordinates of the pointer based on the amount of change in posture; when the virtual coordinates of the pointer are present in a movable region, displays the pointer at a position of the virtual coordinates; when the virtual coordinates of the pointer are present outside the movable region, displays the pointer at a position in the movable region closest to the virtual coordinates; and when the virtual coordinates of the pointer have reached a boundary of a clip region, limits the virtual coordinates of the pointer within the clip region.

Abstract: A user interface creator included in a recording and playback apparatus creates a plurality of selection screens for selecting, by a user, a desired program from among a plurality of recorded programs. The selection screens arrange and display a plurality of pieces of program information classified by different classification methods each other. When a predetermined user command is received during playback of a program, the user interface creator creates a user interface image that is for selecting, by the user, program information and that is displayed so as to be partially superimposed on video of the program being played back. The user interface image displays pieces of program information classified using a classification method that conforms to a classification method for the selection screen used when the program being played back is selected.

The selection screens arrange and display a plurality of pieces of program information classified by different classification methods each other. When a predetermined user command is received during playback of a program, the user interface creator creates a user interface image that is for selecting, by the user, program information and that is displayed around video of the program being played back. The user interface image displays a region representing program information or a classification type classified using a classification method that conforms to a classification method for the selection screen used when the program being played back is selected.

Abstract: A data acquisition apparatus including: a data acquiring unit 507 which receives data acquisition conditions, and when transmitted data includes pieces of data that satisfy any request conditions, extracts the pieces of data from the transmitted data; a data acquisition request receiving unit 501 which receives requests to acquire data from a plurality of applications, together with conditions specifying the data; and a request condition setting scheduling unit 113 which exercises a control to start data acquisitions by scheduling the data acquisitions for all the received requests to generate a queue of the requests, and setting corresponding conditions in the data acquiring unit 507 in accordance with the queue.
