Abstract:
1. A method for encoding video content, the method comprising: receiving a plurality of full-pel pixel values corresponding to each line of a plurality of lines of full-pel pixels; for each line of the plurality of lines, determining an interpolated sub-pel pixel value for each of three sub-pel pixels between two adjacent full-pel pixels, the three sub-pel pixels being a half-pel pixel, a first quarter-pel pixel and a second quarter-pel pixel between the two adjacent full-pel pixels, by: outputting each interpolated sub-pel pixel value for use in a motion compensation operation, wherein the set of coefficients used to determine an interpolated sub-pel pixel value for the half-pel pixel is different from the set of coefficients used to determine an interpolated sub-pel pixel value for the first quarter-pel pixel and from the set of coefficients used to determine an interpolated sub-pel pixel value for the second quarter-pel pixel.
