1. An apparatus for decoding video information, the apparatus comprising: a memory configured to store video data associated with a base layer (BL), an enhancement layer (EL), or both, wherein the BL comprises one or more BL pictures having a first BL spatial dimension value and a second BL spatial dimension value, and the EL comprises one or more EL pictures having a first EL spatial dimension value and a second EL spatial dimension value; and a processor operationally coupled to the memory and configured to: determine (i) a first scaling factor based on the first BL spatial dimension value and the first EL spatial dimension value and (ii) a second scaling factor based on the second BL spatial dimension value and the second EL spatial dimension value, wherein the first scaling factor is different from the second scaling factor; spatially scale a first component of an element associated with the BL using the determined first scaling factor as an input to a scaling function, wherein the scaling function is configured to temporally scale motion vectors to generate temporal motion vector predictors (TMVPs); spatially scale a second component of the element associated with the BL using the determined second scaling factor as an input to the scaling function; and decode at least a portion of the EL using the spatially scaled first and second components of the element.
