Claim 11:
12. A method of decoding a bitstream by an electronic device, the method comprising:
receiving an image frame of the bitstream;
determining a block unit from the received image frame;
determining an intra prediction mode index of the determined block unit based on the bitstream;
determining a plurality of reference samples neighboring the determined block unit;
comparing the determined intra prediction mode index with a plurality of predefined indices each corresponding to an angle parameter divisible by a predefined value;
generating a plurality of filtered samples by one of a plurality of sample filters selected based on the comparison, the plurality of filtered samples determined based on the determined plurality of reference samples, wherein the selected one of the plurality of sample filters comprises a reference filter when the determined intra prediction mode index is equal to one of the plurality of predefined indices; and
reconstructing the determined block unit based on the generated plurality of filtered samples and the determined intra prediction mode index.
