Claim Text:
1. A computer-readable medium storing computer executable instructions for causing a processor programmed thereby to perform operations, the computer-readable medium being selected from the group consisting of only a non-volatile memory, magnetic disk storage, CD ROM, and DVD, the operations comprising: encoding a first video frame of a video sequence using intraframe coding, including: computing a spatial extrapolation for a current block of pixel values in the first video frame; computing a spatial-extrapolation residual based upon the current block in the first video frame and the spatial extrapolation; and applying a re-oriented frequency transform to pixel values of the spatial-extrapolation residual to produce transform coefficients of the spatial-extrapolation residual, wherein the re-oriented frequency transform addresses non-stationarity in the pixel values of the spatial-extrapolation residual due to the spatial extrapolation; outputting encoded video data for the first video frame in a bitstream; encoding a second video frame of the video sequence, including:
