Abstract: The present invention relates to a method for superimposing images on three- dimensional content, wherein a video stream is received which comprises the three- dimensional content and a depth map for superimposing images on the three- dimensional content. Once the video stream has been received, images are superimposed on the three-dimensional content in a position in depth dependent on the superimposition depth map (DM). The superimposition depth map contains information about the depth of the three-dimensional content and is inserted as an image contained in a frame (C) of the video stream. The depth map has a smaller number of pixels than that of a two-dimensional image associated with the three-dimensional content. The invention also relates to devices enabling the implementation of said methods.
