Abstract: The present invention encodes a warp map by using a video codec such as a multi-view texture image by a warp converter, and decodes a warp map by using a video codec such as a multi-view texture image by using a warp inverter. The present invention may incur less additional costs because it does not use a dedicated warp map coder. In addition, the present invention may convert a warp map by using a warp map converter and send the converted map to an encoder and invert decoded warp map information by using a warp map inverter so that the warp map is encoded and decoded by using a video codec such as a multi-view texture image. In addition, it is possible to increase compatibility by enabling various kinds of supplementary data to be used. In addition, it is possible to increase technique compatibility by simply applying a warp map scheme to a 3D video coding technique using a depth map.
