Abstract: According to the present invention, when video resolution is changed, the TV receiver selects resolution having a priority to the graphics resolution requested by the application depending on the application types, or the TV receiver selects graphics resolution appropriate for video format resolution, thereby the TV receiver enables the clear display of graphics without causing any distortion.

Abstract: Conventionally, when the version of a program has been upgraded, the whole of a currently stored program needs to be deleted to be replaced by a new program, and authentication needs to be performed again on such new program when it is activated. However, since the whole of the program is required to be stored and authenticated even when only a part of such program has changed, it consumes time and leads to the decrease in responsiveness. In order to solve this problem, the present invention extracts a difference between a new program and a currently stored old program, when such new program is to be stored, and the new program is to be stored after authentication is performed only on such difference.

Abstract: Example embodiments of the present invention provide the ability to control or set the electromotive force (emf) potential observed in an electronic component by adjusting the resistivity at conducting junctions within it. More specifically, at joints where emf potentials exist due to conducting materials of different types (e.g., two different metals), the resistivity of these conducting junctions is varied, which sets the overall polarity of the emf observed across the component itself. In other words, varying the resistivity at conducting junctions relative to one another, example embodiments control the polarity of the emf within the component itself. As such, the components may then be connected in series or other manner to reduce the overall emf potential induced into a system.

Abstract: To provide a program execution device which is capable of notifying time and information related to download and activation of a program. The AM (1205b) of a terminal device includes: a program activation history obtainment unit (2002) which obtains history information of a program which has been downloaded and activated; a program activation time measurement unit (2004) which measures the time needed for download (download time) of the program and the time needed for activation (activation time) of the program; and a program activation information notification unit (2005) which notifies the activation waiting time based on the history information of the program.

Abstract: The present invention is a video information charging system in which a fee-requiring program is broadcast from a transmitting apparatus (11) to a receiving apparatus (13). Moreover, in the video information charging system, a communication concerning an electronic commerce transaction for a commodity that appears in the program is performed between the receiving apparatus (13) and a commerce management apparatus (14). At a program data generating section (21), a related program for making a display concerning the commodity that appears in the program and conducting an electronic commerce transaction for the commodity is acquired. A control section (33) reproduces data of the program. Moreover, the control section (33) makes the display concerning the commodity that appears in the program in accordance with an instruction from a viewer. Furthermore, the control section (33) transmits a purchase request for the commodity to the commerce management apparatus in accordance with an instruction from the viewer.
