1. A method of executing functions of digital television (DTV) with a three-dimensional (3D) pointing device, the method comprising:

  • selecting by the DTV one of a plurality of functions provided by the DTV in response to a selection signal received from the 3D pointing device, each function having a corresponding execution profile;

    receiving by the DTV a motion parameter sensed by the 3D pointing device, the motion parameter including a direction of continuous movement of the 3D pointing device and a distance corresponding to the direction of continuous movement; and

    executing the selected function by the DTV in accordance with the corresponding execution profile and the received motion parameter,wherein the corresponding execution profile includes a correspondence between a rate of change of an execution speed of the selected function and a change of the distance corresponding to the direction of continuous movement,wherein the distance of continuous movement comprises a plurality of sections having a common length,wherein the rate of change of the execution speed includes plural rates of change corresponding to the plurality of sections, andwherein each of the plural rates of change are different from each other.
