    • 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.
    • 层间运动映射信息可以用于启用比特流的增强层的时间运动矢量预测(TMVP)。 例如,可以确定层间视频块的参考图像和运动矢量(MV)。 可以基于并置的基本层视频块来确定参考图像。 例如,参考图片可以是并置的基本层视频块的参考图片的并置的层间参考图片。 可以基于并置的基本层视频块的MV来确定MV。 例如,可以通过确定并置的基本层视频块的MV并根据基本层和增强层之间的空间比来缩放并置的基本层视频块的MV来确定MV。 可以使用层间视频块的MV在增强层图像上执行TMVP。
