Abstract: A method includes decompressing first compressed video data to provide uncompressed video data in a first order. The method includes compressing the uncompressed video data to provide second compressed video data in a second order. The decompressing and compressing are based on first and second compression rates, respectively. The first order may be based on fundamental blocks of a frame of video data and the second order is based on lines of the frame of video data. The compressing may include alternating compression of partial portions of a first line of uncompressed video data with compression of partial portions of at least a second line of uncompressed video data to thereby generate a first line of compressed video data corresponding to the first line of uncompressed video data and at least a second line of compressed video data corresponding to the second line of uncompressed video data.

Abstract: A pixel interpolation process is based on detection of a potential edge in proximity to a pixel being estimated, and the angle thereof. The potential edge and its angle is determined based on filtering of offset or overlapping sets of lines from a pixel window centered around the pixel being estimated and then cross-correlating the filter results. The highest value in the correlation result values represents a potential edge in proximity to the pixel being estimated and the index of the highest value represents the angle of the potential edge. This information is used in conjunction with other information from the cross-correlation and analysis of the differences between pixels in proximity to verify the validity of the potential edge. If determined to be valid, a diagonal interpolation based on the edge and its angle is used to estimate the pixel value of the pixel. Otherwise, an alternate interpolation process, such as vertical interpolation, is used to estimate the pixel value for the pixel.
