    Abstract: A video transmission device, according to embodiments of the present invention, comprises: a target view prediction controller for predicting, from a texture picture or a depth picture of an anchor viewing position, a picture for a target viewing position on the basis of target viewing position information; a prediction error controller for processing a prediction error with respect to the predicted picture on the basis of a source picture of the target viewing position, wherein an error-prone region map is generated on the basis of the predicted picture and the source picture; a patch packing controller for patch packing the prediction error-processed picture on the basis of the error-prone region map; and an encoder for encoding the packed patch on the basis of the texture picture or the depth picture of the anchor viewing position. A video transmission method, according to embodiments of the present invention, comprises the steps of: predicting, from a texture picture or a depth picture of an anchor viewing position, a picture for a target viewing position on the basis of target viewing position information; processing a prediction error with respect to the predicted picture on the basis of a source picture of the target viewing position, wherein an error-prone region map is generated on the basis of the predicted picture and the source picture; patch packing the prediction error-processed picture on the basis of the error-prone region map; and encoding the packed patch on the basis of the texture picture or the depth picture of the anchor viewing position.
