Abstract

Devices and methods of intra prediction of a block of a picture are provided. The method includes: obtaining information of Intra Sub-Partitions (ISP), where the information of ISP indicates whether ISP is used for splitting a current block; and selecting a set of coefficients of an interpolation filter based on the information of ISP, where the set of coefficients of the interpolation filter is fG coefficients or fC coefficients. The method further includes obtaining predicted samples of the current block by applying the set of coefficients to reference samples. When the information of ISP indicates whether ISP is used for splitting a current block (i.e., ISP is on), the method removes mode dependency during selection of interpolation filter type. This could increase encoding or decoding efficiency.
