Abstract: The present invention relates to a data information display method of a data broadcasting receiver and an apparatus thereof, in particular to a data information display method of a data broadcasting receiver and an apparatus thereof which is capable of selecting a simple data information picture or a data information picture or a general television picture according to a viewer select in a digital data broadcasting, and knowing overall content of the present receiving data information without switching the present audition television picture into the data information picture when the viewer selects the simple data information picture.

Abstract: An infrared pointing type wireless controller includes a system main body which is an objective of pointing, the system main body having transmitting circuit for generating a carrier frequency signal for emitting an infrared ray, and receiving and controlling circuit for receiving a reflected carrier signal and a reflected code signal, and calculating coordinates of a pointed position according to a difference of intensities of received infrared signals, for matching the pointed position to a display screen; and position indicating circuit with which pointing is performed having re-transmitting circuit for passing or blocking reflection of the carrier frequency signal transmitted from the transmitting circuit for generating a required code, and overlapping the code with the carrier frequency signal and reflecting the overlapped signal.

Abstract: Three dimensional wireless pointing device for calculating coordinates and controlling a position of a cursor in a three dimensional space is disclosed, including a transmission side having a plurality of ultrasonic wave generating parts and a single infrared ray emitting part or a single ultrasonic wave generating part and a plurality of infrared ray emitting parts arranged in a certain axis direction at certain angles and a reception side having a plurality of infrared ray receiving sensors and a single ultrasonic wave receiving sensor arranged to cross the ultrasonic wave generating part(s) and the infrared ray emitting part(s) in the transmission side at a right angle, thereby to measure intensities of the infrared ray(s) and the ultrasonic wave(s) varied depending on direction of pointing and calculate a difference of relative arrival times of the infrared ray and the ultrasonic wave to obtain coordinate values of a position in a three dimensional space, whereby a position of cursor or menu, which is a c
