Abstract
In an example, a method of coding video data includes determining a location of a reference sample associated with a reference picture of video data based on one or more scaled offset values, where the reference picture is included in a first layer of a multi-layer bitstream and the one or more scaled offset values indicate a difference in scale between the first layer and a second, different layer. The method also includes determining a location of a collocated reference block of video data in the first layer based on the location of the reference sample, and coding a current block of video data in the second layer relative to the collocated reference block.
