Abstract
An apparatus for coding video information according to certain aspects includes a memory and a processor configured to: determine a value of a first flag indicative of whether preceding pictures that precede a current picture in a current layer in decoding order are used for temporal motion vector prediction (TMVP) of subsequent pictures that follow the current picture in the current layer in decoding order, the first flag associated with the current picture; and refrain from using the preceding pictures in the current layer as reference pictures for TMVP of the current picture, in response to determining that the value of the first flag indicates that the preceding pictures in the current layer should not be used for TMVP of the subsequent pictures in the current layer.
