Patent ID: 7760950

Claim:
A decoding process comprising: computer implemented steps performed by a processor of a video data decoder to implement the following steps: receiving a block of coefficients relating to a block of video information to be displayed; scaling the block of received coefficients to inversely quantize the block of received coefficients; and applying a vertical transform and a horizontal transform to the block of scaled coefficient, in order to reconstruct a signal of the block of video information for display of the video signal, wherein basis vectors of the vertical and horizontal transforms are 1 1 1 1 1 1 1 1 12 / 8 10 / 8 6 / 8 3 / 8 - 3 / 8 - 6 / 8 - 10 / 8 - 12 / 8 1 1 / 2 - 1 / 2 - 1 - 1 - 1 / 2 1 / 2 1 10 / 8 - 3 / 8 - 12 / 8 - 6 / 8 6 / 8 12 / 8 3 / 8 - 10 / 8 1 - 1 - 1 1 1 - 1 - 1 1 6 / 8 - 12 / 8 3 / 8 10 / 8 - 10 / 8 - 3 / 8 12 / 8 - 6 / 8 1 / 2 - 1 1 - 1 / 2 - 1 / 2 1 - 1 1 / 2 3 / 8 - 6 / 8 10 / 8 - 12 / 8 12 / 8 - 10 / 8 6 / 8 - 3 / 8 or multiples thereof or a transpose thereof.
