Abstract: The present invention relates to a method and an apparatus for inducing motion information by using a depth information value. The present invention includes a method of allowing several blocks to share and use a specific depth information value to decrease a memory bandwidth due to approach of the depth information value when motion information is induced by using the depth information value. Thus, the present invention can reduce the memory bandwidth of coding and decoding in a video coding process.
