摘要
A processor for expanding a compressed video signal includes a pixel interpolator which interpolates between input pixel values in two dimensions. This interpolator calculates and stores intermediate pixel values which are interpolated in the vertical direction. A pair of these intermediate pixel values are then fed back into the interpolator which performs a horizontal interpolation to produce pixel values that are interpolated in both the horizontal and vertical dimensions. In steady state operation, the horizontal and vertical interpolation operations are alternated to produce a stream of two-dimensionally interpolated values.
