Systems, methods, and devices for coding video data are described herein. In some aspects, a memory unit is configured to store the video data. The video data may include a base layer and an enhancement layer. The base layer may include a base layer coding unit co-located with a first enhancement layer coding unit in the enhancement layer. A processor may be configured to construct one or more motion vectors based at least in part on one or more base layer motion vectors available at the co-located base layer coding unit. The one or more motion vectors may be associated with the first enhancement layer coding unit. The processor may also be configured to determine pixel values of a neighbor enhancement layer coding unit based at least in part on the one or more motion vectors.
