Filed: 2000-08-01
Abstract: PURPOSE: An apparatus and a method for improving picture quality of a digital television are provided to offer optimized picture quality through adaptive interpolation according to motion of a picture when an interlace picture is converted into a progressive picture. CONSTITUTION: An apparatus for improving picture quality of a digital television includes a variable-length decoder(20), a picture reconstruction unit(30), a motion comparator(50), and a format converter(70). The variable-length decoder receives an MPEG-2 digital video stream of pictures compressed in different degrees according to picture information and calculates the compressed degree of each picture. The picture reconstruction unit run-length-decodes, inverse-scans, inverse-quantizes and 8x8 inverse-discrete-cosine- transforms the digital video stream to restore the state before compression to reconstruct pictures with sampled Y/CbCr values. The motion comparator extracts a motion vector using a difference between the output of the picture reconstruction unit and a picture currently being output and selectively applies time axis interpolation or vertical axis interpolation with reference to the motion vector, to compensate for a varied portion of a picture. The format converter receives the output of the motion comparator to converts the output into a format to be displayed.
