At least one embodiment relates to a method for padding a first depth image representative of depth values of nearer points of a point cloud frame and a second depth image representative of depth values of farther points of a point cloud frame. The method also comprises encoding a video stream including a time-interleaving of said encoded first and second images. There is also provided a method comprising decoding a video stream to provide a first depth image representative of depth values of nearer points of a point cloud frame and a second depth image representative of depth values of farther points of a point cloud frame; and filtering pixel values of the second depth image by using pixel values of the first depth image.
