Abstract:
In one embodiment, an apparatus configured to code video data includes a processor and a memory unit. The memory unit stores video data associated with a first layer having a first spatial resolution and a second layer having a second spatial resolution. The video data associated with the first layer includes at least a first layer block and first layer prediction mode information associated with the first layer block, and the first layer block includes a plurality of sub-blocks where each sub-block is associated with respective prediction mode data of the first layer prediction mode information. The processor derives the predication mode data associated with one of the plurality of sub-blocks based at least on a selection rule, upsamples the derived prediction mode data and the first layer block, and associates the upsampled prediction mode data with each upsampled sub-block of the upsampled first layer block.
