Abstract:
A method of utilizing an 8-bit primary transform core matrix to decode/encode may include determining whether to use a first transform core matrix that is a DST-7 primary transform core matrix which is larger than or equal to 8-point and represented by 8-bits. When a result of the determination is to use the first transform core matrix, the method may include: (i) deriving the first transform core based on a set of unique numbers, and (ii) causing a target data block to be encoded or decoded using the derived primary transform core. The method may further include, when a result of the determination is to not use the first primary transform: (i) deriving a second transform core based on the same set of unique numbers, and (ii) causing the target data block to be encoded or decoded using the derived second transform core.

Claim (Index 11):
An apparatus for utilizing an 8-bit primary transform core matrix to decode compressed video or image data or encode uncompressed video or image data, the apparatus comprising:\n at least one memory configured to store computer program code; and at least one processor configured to access the at least one memory and operate according to the computer program code, the computer program code comprising:\n first applying code configured to cause the at least one processor to receive information regarding a target data block for encoding or decoding, the target data block for encoding or decoding being one of: a compressed video or image data block or an uncompressed video or image data block; \n second applying code configured to cause the at least one processor to determine, for the encoding or decoding of the target data block, whether to use a first transform core matrix that is a DST-7 primary transform core matrix that is larger than or equal to 8-point and that is represented by 8-bits; \n third applying code configured to cause the at least one processor to when a result of the determination is to use the first transform core matrix: (i) construct the 8-bit DST-7 primary transform core matrix based on a set of M unique numbers, and (ii) cause or transmit information that causes the target data block for encoding or decoding to be encoded or decoded using the derived 8-bit DST-7 primary transform core matrix; and \n fourth applying code configured to cause the at least one processor to when a result of the determination is to not use the first primary transform core matrix: (i) construct a second primary transform core matrix based on the same set of M unique numbers, and (ii) cause or transmit information that causes the target data block for encoding or decoding to be encoded or decoded using the derived second primary transform core matrix, wherein the second primary transform core matrix is a different type of primary transform core matrix than a type of the DST-7 primary transform core matrix and the second primary transform core matrix is one of DCT-8, DST-1 or DCT-5.
