Patent ID: 8760495

Claim:
A method for processing a video signal, the method comprising: receiving a multi-view video coded bit stream including color pictures and depth pictures, wherein the depth picture indicates a group of digitalized information on a distance between a base camera and an object; acquiring data type identification information from the multi-view video coded bit stream, wherein the data type identification information indicates whether or not depth-coded data are included in the multi-view video coded bit stream; acquiring reference information between views of the depth picture based upon the data type identification information, wherein the reference information between views of the depth picture includes a number of depth-view reference pictures, and a view identification number of the depth-view reference picture; acquiring an estimation value of the depth picture by using the reference information between views of the depth picture; recovering the depth picture by using the estimation value of the depth picture; and acquiring a 3-dimensional image by using the recovered depth picture, wherein the multi-view video coded bit stream includes a base view and a non-base view of both color pictures and depth pictures, wherein the base view indicates a view that can be decoded independently from other views without using a prediction between views, and wherein the non-base view indicates a view other than the base view, and wherein, in case of the base view, the color picture is transmitted earlier than the depth picture, and wherein, in case of the non-base view, the depth picture is transmitted earlier than the color picture.
