Abstract: A first interpolation filter is selected for a first direction of the prediction block, and a second interpolation filter is selected for a second direction of the prediction block. The first interpolation filter has a first number of taps and the second interpolation filter has a second number of taps. The second interpolation filter is set to an interpolation filter having a third number of taps in response to determining that the first number of taps is greater than a threshold number of taps and the second number of taps is greater than a threshold number of taps. The third number of taps is smaller than or equal to the threshold number of taps. The prediction block is generated using the first interpolation filter and the second interpolation filter.
