Abstract:
A method of utilizing an 8-bit primary transform core matrix to decode compressed video or image data or encode uncompressed video or image data. The method may include determining whether to use a first transform core matrix that is of a first size type or a second transform core matrix that is of a second size type that is smaller than the first size type. When a result of the determination is to use the first transform core matrix, encoding or decoding the target file using the 8-bit primary transform core matrix that has the size that is 64-point or larger. If not, the method may include extracting the second transform core matrix of the second size type from the first transform matrix and encoding or decoding the target file using the extracted second transform core matrix.

Claim (Index 18):
The apparatus according to  claim 11 , wherein\n the first transform core matrix is an 8-bit, N-point primary transform core matrix, which is composed of M unique numbers, and the fourth applying code is further configured to cause the at least one processor to derive the 8-bit, N-point primary transform core matrix by performing the following steps:\n deriving an initial transform core matrix T1 by scaling an original transform core which is composed by floating-point numbers T0 using a scaling factor 2B\u22122\u00d7log 2(N) such that T1=T0\u00d72 B-2 \u00d7log 2 (N), where B=8, and the row vectors of T0, which are basis vectors, are orthogonal to each other, and the norm of each row vector is 1; \n deriving an adjusted transform core matrix T2 by adding offsets on a selected set of the M unique numbers which are used to construct the adjusted primary transform core matrix T2; \n calculating a cost value C as the sum of absolute values of all elements of (T1*T1 T \u22122 2B-4 \u00d7log 2 (N) 2 \u00d7I), where I is an N\u00d7N identity matrix; and \n updating the adjusted transform matrix T2 by adding the calculated offset values to T2, which minimizes the cost value to T2, which is output as the 8-bit, N-point primary transform core matrix.
