  • Patent number: 7880813
    Abstract: A control device includes a control section standing by to receive a control signal transmitted from a transmission section. The control section assigns, respectively to N or less control signals, instructions to be executed when the control signals are received, and generates a signal for drawing on a display device an operation menu which includes N image regions placed in an arrangement corresponding to the N sensing portions of the transmission section. Each image region represents an instruction assigned to a control signal which is transmitted when the corresponding sensing portion is pressed, such that the N instructions to be respectively assigned to the control signals are determined based on an operation state of an apparatus to be controlled in the standby state and the operation menu generated in an immediately previous standby state.

  • Patent number: 7590995
    Abstract: In the case when EPG data of multiple channels is displayed on a display, if the data is attempted to be downsized uniformly and displayed, information of each displayed program is displayed smaller. Hence, such information becomes very difficult for humans to see. The present invention provides an EPG display apparatus comprising second storage means of storing three-dimensional EPG data obtained by mapping all or part of two-dimensional EPG data on the side face of a cylinder in a three-dimensional space, and control means of displaying all or part of the three-dimensional EPG data stored in the second storage means on a display having a two-dimensional screen.
