There are provided a method and apparatus for reusing available motion information as a motion estimation predictor for video encoding. A rebate is calculated periodically based on credit card usage and the rebate is applied to fund the investment account periodically. The electrical signal generated from the leading detector is delayed, based on a distance between beams and the speed of the media, to achieve a desired amount of temporal coincidence with the electrical signal associated with the lagging beam. The resource access control unit obtains a request of accessing the control target resources from the program and determines permission of the access request based on the identification information. The virtual shape template may define a cutting path for extracting the projection screen from a suitable material. A universal applicability of a remote control unit is ensured by means of a compression method by which the display content of a control unit is transmitted essentially identically onto the display screen of the remote control unit.
