Abstract:
A method and apparatus for video encoding or decoding performed by a video encoder or a video decoder incorporating advanced multiple transform (AMT) are disclosed. According to this method, a transform set consisting of two type candidates designated as a first type and a second type is determined, where the first type and the second type are different. If AMT is used by the current block, a vertical transform is selected from the transform set and a horizontal transform is selected from the transform set. A transform index, for indicating both vertical transform selection and horizontal transform selection, can be signaled at the encoder side or the transform index is parsed at the decoder side. Another method and apparatus incorporating AMT are also disclosed where the transform set is determined according to the resolution of current MVD.

Claim (Index 19):
A method for encoding or decoding video data, the method comprising:\n receiving input data associated with a current block coded in an Inter prediction mode, wherein the input data corresponds to the current block to be processed by a forward transform process at an encoder side and the input data corresponds to a current coefficient block to be processed by an inverse transform process at a decoder side; determining resolution of current MVD (motion vector differences) associated the current block; determining a transform set according to the resolution of current MVD; selecting a vertical transform and a horizontal transform from the transform set; and generating a current coefficient block according to the current block, the vertical transform and the horizontal transform at the encoder side or recovering the current block according to the current coefficient block, a vertical inverse transform associated with the vertical transform and a horizontal inverse transform associated with the horizontal transform at the decoder side.
