Abstract:
Inter-layer motion mapping information may be used to enable temporal motion vector prediction (TMVP) of an enhancement layer of a bitstream. For example, a reference picture and a motion vector (MV) of an inter-layer video block may be determined. The reference picture may be determined based on a collocated base layer video block. For example, the reference picture may be a collocated inter-layer reference picture of the reference picture of the collocated base layer video block. The MV may be determined based on a MV of the collocated base layer video block. For example, the MV may be determined by determining the MV of the collocated base layer video block and scaling the MV of the collocated base layer video block according to a spatial ratio between the base layer and the enhancement layer. TMVP may be performed on the enhancement layer picture using the MV of the inter-layer video block.

Claim (Index 51):
The decoder of  claim 50 , wherein the processor, to decode the enhancement layer picture based on the MV field of the inter-layer picture, is configured to:\n determine a MV field of the enhancement layer picture based on the MV field of the inter-layer picture, wherein the MV field of the inter-layer picture comprises a MV and a reference picture index of a video block of the inter-layer picture; and decode the enhancement layer picture based on the MV field of the enhancement layer picture.
