Method and apparatus for processing video signal

An apparatus for processing a video signal comprising:

• an inter prediction unit configured to acquire a disparity vector of a target block, wherein the disparity vector indicates a difference between a position of the target block contained in a current viewpoint and a position of a reference block contained in a neighbor viewpoint;
• a motion vector list generator configured to identify whether reference picture of the target block is identical with reference picture of a neighbor block and determine a motion vector list for the target block based on identifying, wherein the motion vector list is composed of one or more motion vector candidates for a predicted motion vector of the target block, and the motion vector candidate includes at least one of a spatial motion vector, a temporal motion vector, and the disparity vector;
• and
• a parsing unit configured to extract motion vector identification (ID) information for the target block from a bitstream, wherein the motion vector ID information is used to specify a motion vector candidate contained in the motion vector list used as a predicted motion vector of the target block,
• wherein the inter prediction unit determines a predicted motion vector of the target block being a motion vector candidate corresponding to the motion vector ID information, and the inter prediction unit performs motion compensation on the basis of the predicted motion vector.
