This disclosure describes techniques for coding information in a scalable video coding (SVC) scheme that supports spatial scalability. In one example, a method of coding information in a SVC scheme comprises coding first video blocks defined in a base layer of the SVC scheme, and coding second video blocks defined in an enhancement layer of the SVC scheme, wherein the second video blocks provide spatial scalability enhancement relative to the first video blocks. The coding of the second video blocks includes performing inter-layer prediction for the enhancement layer relative to the base layer for a first subset of the second video blocks that fully overlap the first video blocks, and performing inter-layer prediction for the enhancement layer relative to the base layer for a second subset of the second video blocks that partially overlap the first video blocks.
