Abstract
An apparatus includes a communication interface configured to receive a bitstream for a compressed video and a processor operably coupled to the communication interface. The processor is configured to decode the bitstream for the compressed video and obtain reference samples associated with a block of a video frame. The processor is also configured to determine an interpolation filter type for use in obtaining predicted samples. The processor is also configured to select an interpolation filter of the interpolation filter type based on a block size of the block of the video frame. The processor is also configured to apply the interpolation filter to the reference samples. The processor is also configured to output one or more predicted samples using the interpolated reference samples.
