1. A method for processing a video signal by a video decoder, comprising: obtaining a temporary inter-view motion vector for a current block; obtaining inter-view motion vector correction information indicating whether a reference view block is obtained using the temporary inter-view motion vector; obtaining the reference view block based on the inter-view motion vector correction information and the temporary inter-view motion vector, wherein when the inter-view motion vector correction information indicates that the reference view block is obtained using the temporary inter-view motion vector, a block indicated by the temporary inter-view motion vector is acquired as the reference view block; obtaining an inter-view motion vector for the current block using a reference depth block corresponding to the reference view block, the inter-view motion vector for the current block being obtained using at least one depth value of the reference depth block; and decoding the current block using the inter-view motion vector for the current block, wherein when the inter-view motion vector correction information indicates that the reference view block is not obtained using the temporary inter-view motion vector, the temporary inter-view motion vector is acquired as the inter-view motion vector for the current block.
