1. An apparatus for reconstructing a multi-view signal coded into a data stream, comprising:
a depth estimator configured to obtain, using a processor, a depth map estimate of a current picture in a dependent view of the multi-view signal; and
a dependent-view reconstructor configured to, using the processor:
determine a disparity vector for at least one block of blocks of the current picture in the dependent view of the multi-view signal based on the depth map estimate, the disparity vector representing a disparity between the current picture of the dependent view and a current picture of a reference view of the multi-view signal at the at least one block of the current picture of the dependent view;
determine, for the at least one block of the current picture of the dependent view, a list of motion vector predictor candidates; and
identify, for the at least one block of the current picture of the dependent view, a motion vector predictor candidate from the list of motion vector predictor candidates; and
reconstruct the at least one block of the current picture of the dependent view by performing a motion-compensated prediction of the at least one block of the current picture of the dependent view using a motion vector which depends on the identified motion vector predictor candidate.
