1. An apparatus for reconstructing a multi-view signal coded in a data stream, comprising:
a dependent view reconstructor configured for:
processing a list of motion vector candidates associated with a coding block of a current picture in a dependent view of the multi-view signal, the processing including:
estimating a motion vector based on a disparity vector related to the coding block of the current picture in the dependent view, wherein the disparity vector represents a disparity between the current picture in the dependent view and the current picture in a reference view of the multi-view signal,
adding the motion vector into the list of motion vector candidates, and
extracting, from the data stream, index information that indicates a selected motion vector of the list of motion vector candidates; and
reconstructing the coding block in the current picture of the dependent view by performing the motion-compensated prediction based on the selected motion vector.
