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.

Abstract translation: 本发明涉及一种在三维内容上叠加图像的方法，其中接收包括三维内容的视频流和用于在三维内容上叠加图像的深度图。 一旦已经接收到视频流，则在依赖于叠加深度图（DM）的深度位置上将图像叠加在三维内容上。 叠加深度图包含关于三维内容的深度的信息，并被插入作为包含在视频流的帧（C）中的图像。 深度图具有比与三维内容相关联的二维图像的像素数更少的像素数。 本发明还涉及能够实现所述方法的装置。
