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.

Abstract: The present invention relates to a method for processing a video signal, comprising the step of inducing an inter-view motion vector of a current texture block by considering priorities between inter-view motion vector candidates of the current texture block, wherein the inter-view motion vector candidates include an inter-view motion vector of a spatial neighboring block, an inter-view motion vector of a temporal neighboring block and/or a reference inter-view motion vector, and inter-view inter prediction is performed by using the induced inter-view motion vector. The present invention can increase the accuracy of the inter-view inter prediction by selectively using the inter-view motion vector of a spatial neighboring block, the inter-view motion vector of a temporal neighboring block and/or the reference inter-view motion vector to induce an accurate inter-view motion vector, and can improve coding efficiency by reducing the amount of residual data to be transmitted.
