    摘要： Provided are a filtering method and apparatus for removing blocking artifacts and/or ringing noise. The filtering apparatus includes (a) performing one-dimensional discrete cosine transform (1D DCT) on video data on a block-by-block basis in a horizontal or vertical direction; (b) performing 1D DCT in the other direction of (a) and quantization on at least one of 1D DCT coefficients for a pixel obtained by performing 1D-DCT on the video data, the pixel being selected according to pixel position; and (c) generating filtering information based on the quantized pixel coefficient obtained from (b). According to the filtering method and apparatus, it is possible to reduce the amount of calculation when obtaining filtering information to remove the blocking artifacts and/or ringing noise.

    摘要： An interpolation method and apparatus for motion vector compensation are provided. The interpolation method includes calculating a horizontal sum of values of a plurality of half-pixels adjacent to or near a predetermined quarter-pixel in the horizontal direction by giving predetermined weights to each of the half-pixels, and adding the results; calculating a vertical sum of values of a second plurality of half-pixels adjacent to or near the quarter-pixel in the vertical direction by giving predetermined weights to each of the half-pixels, and adding the results; and calculating an integer value of the quarter-pixel value using the vertical and horizontal sums. According to an aspect of the invention, more consistent and reliable compensation for error in a motion vector may be achieved, thereby increasing the efficiency of motion vector compensation.
