Abstract: PURPOSE: A digital-analogue converter is provide to improve a operating speed and a performance. CONSTITUTION: The digital-analogue converter comprises a first terminal and a second terminal, a plurality of a first resistors and a second resistors, a plurality of capacitors(110), a selective control circuit(120) and a output circuit(130). A reference voltage(101) is applied to the first terminal. A plurality of the first resistors are connected in series between the first terminal and ground, and a plurality of the second resistors are connected between ground and the contact point of the first resistors including the first terminal. An electric charge corresponding to digital signal is transmitted to the second terminal. One end of the capacitors is connected in common with the second terminal. The selective control circuit is selectively connected with the contact point of the first resistors and the capacitors in response to the digital signal. The output circuit outputs a quantity of electric charge charged in the capacitor by the selective control circuit to analogue signal corresponding to the digital signal. The first resistors and the second resistors is arranged in the ratio of 1 to 2.

Abstract: PURPOSE: A digital to analog converting apparatus for 3d implementation is provided to watch 3D images in a conventional 2D TV by applying a function of implementing 3D to a digital to analog converting apparatus. CONSTITUTION: An RF(Radio Frequency) tuner(10) receives a broadcast signal. An AD converter(20) changes the broadcast signal received through the RF tuner into a digital signal. A TS(Transport Stream) parser(30) parses a transport stream which is transformed to the digital signal. A decoder(40) decodes a parsed signal. A 3D anaglyph converter(50) extracts a left-eye image and a right-eye image from a decoded signal. The 3D anaglyph converter generates 3D images by editing an extracted left-eye image and right-eye image. An DA converter(60) changes the 3D images into an analog signal.
