Abstract:
A method for decoding video includes receiving quantized coefficients representative of a block of video representative of a plurality of pixels. The quantized coefficients are dequantized based upon a function of a remainder. The dequantized coefficients are inverse transformed to determine a decoded residue.

Claim (Index 2):
An apparatus for decoding video, the apparatus comprising one or more processors and one or more storage devices storing instructions that when executed by the one or more processors cause the one or more processors to perform operations comprising:\n (a) receiving quantized coefficients representative of a block of video representative of a plurality of pixels; (b) descaling the quantized coefficients by multiplying the quantized coefficients with numbers dependent on a coefficient index and a transform size of the block to generate descaled coefficients; (c) applying an adjustment to the descaled coefficients to generate adjusted descaled coefficients, wherein the adjustment is a variable based on the transform size; (d) clipping the adjusted descaled coefficients to a predetermined bit depth to generate clipped coefficients; (e) one-dimensional inverse transforming the clipped coefficients in a first direction to generate first direction inverse transformed coefficients; (f) shifting the first direction inverse transformed coefficients to generate shifted coefficients; (g) clipping the shifted coefficients to the predetermined bit depth to generate second clipped coefficients; and (h) one-dimensional inverse transforming the second clipped coefficients in a second direction to determine a decoded residue, wherein the applying the adjustment is performed after the descaling, and wherein the shifting is performed after the one-dimensional inverse transforming in the first direction and prior to the one-dimensional inverse transforming in the second direction.
