Abstract

In one embodiment, a video coder for coding video data includes a processor and a memory. The processor selects a filter set from a multiple filter sets for upsampling reference layer video data based at least on a prediction operation mode for enhanced layer video data and upsamples the reference layer video data using the selected filter set. Some of the multiple filter sets have some different filter characteristics from one another, and the upsampled reference layer video data has the same spatial resolution as the enhanced layer video data. The processor further codes the enhanced layer video data based at least on the upsampled reference layer video data and the prediction operation mode. The memory stores the upsampled reference layer video data.
