摘要
A method and apparatus for decoding a video sequence using a discrete sine transform (DST) type-VII transform core includes generating a set of tuples of transform core elements associated with an n-point DST-VII transform core. A first sum of a first subset of transform core elements of a first tuple is equal to a second sum of a second subset of remaining transform core elements of the first tuple. The n-point DST-VII transform core is generated based on generating the set of tuples of transform core elements. A transform on a block is performed using the n-point DST-VII transform core.
