A method of encoding video information, the method comprising: receiving video information associated with an enhancement layer and a base layer, the base layer comprising a reference region and a region outside the reference region, wherein the reference region is a cropped region of the base layer, wherein the reference region is available for inter-layer prediction of the enhancement layer, wherein the region outside the reference region is not available for inter-layer prediction of the enhancement layer, and wherein the enhancement layer comprises blocks which correspond to respective blocks in the base layer; encoding the base layer; and encoding the enhancement layer, wherein encoding the enhancement layer comprises: using the reference region of the base layer for inter-layer prediction of the enhancement layer; mapping coordinates which identify a current enhancement layer block to corresponding coordinates of a mapped position in the base layer; determining whether the mapped coordinates are outside the reference region of the base layer; and in response to determining that the mapped coordinates are outside the reference region of the base layer, determining that the corresponding base layer block is unavailable for predicting the current block, and disabling inter-layer prediction of syntax elements for the current enhancement layer block. receiving video information associated with an enhancement layer and a base layer, the base layer comprising a reference region and a region outside the reference region, wherein the reference region is a cropped region of the base layer, wherein the reference region is available for inter-layer prediction of the enhancement layer, wherein the region outside the reference region is not available for inter-layer prediction of the enhancement layer, and wherein the enhancement layer comprises blocks which correspond to respective blocks in the base layer; encoding the base layer; and encoding the enhancement layer, wherein encoding the enhancement layer comprises: using the reference region of the base layer for inter-layer prediction of the enhancement layer; mapping coordinates which identify a current enhancement layer block to corresponding coordinates of a mapped position in the base layer; determining whether the mapped coordinates are outside the reference region of the base layer; and in response to determining that the mapped coordinates are outside the reference region of the base layer, determining that the corresponding base layer block is unavailable for predicting the current block, and disabling inter-layer prediction of syntax elements for the current enhancement layer block. using the reference region of the base layer for inter-layer prediction of the enhancement layer; mapping coordinates which identify a current enhancement layer block to corresponding coordinates of a mapped position in the base layer; determining whether the mapped coordinates are outside the reference region of the base layer; and in response to determining that the mapped coordinates are outside the reference region of the base layer, determining that the corresponding base layer block is unavailable for predicting the current block, and disabling inter-layer prediction of syntax elements for the current enhancement layer block.
