Abstract
A method and apparatus for changing the number of scan lines in a frame of video data to produce an image represented by the video data that corresponds to a desired aspect ratio. The apparatus includes a pair of finite impulse response filters for processing the decoded chrominance and luminance pixel values stored in memory. The filters permit a plurality of scan lines of chrominance and luminance data to be read and filtered on a continuous basis with any scan line of data being read only once. Thus, the filters provide a very efficient method of providing a frame of a number of output scan lines of chrominance and luminance pixel values that are different from the number of scan lines of chrominance and luminance pixel values in a frame of video data stored in memory.
