Abstract
An apparatus configured to code video information includes a memory and a processor in communication with the memory. The memory is configured to store video information associated with a reference layer and an enhancement layer, the reference layer comprising a reference layer (RL) picture having a first slice and a second slice, and the enhancement layer comprising an enhancement layer (EL) picture corresponding to the RL picture. The processor is configured to generate an inter-layer reference picture (ILRP) by upsampling the RL picture, the ILRP having a single slice associated therewith, set slice information of the single slice of the ILRP equal to slice information of the first slice, and use the ILRP to code at least a portion of the EL picture. The processor may encode or decode the video information.
