1. A method of encoding a video data signal ( 15 ), the method comprising: providing color information ( 51 ) for pixels in an image, providing a depth map with depth information ( 52 ) for the pixels, providing transition information ( 56 , 57 , 60 , 70 , 71 ) being representative of a width ( 63 , 73 ) of a transition region ( 61 , 72 ) in the image, the transition region ( 61 , 72 ) comprising a depth transition ( 62 ) and blended pixels in which colors of a foreground object and a background object are blended, generating ( 24 ) the video data signal ( 15 ) comprising encoded data representing the color information ( 51 ), the depth map ( 52 ) and the transition information ( 56 , 57 , 60 , 70 , 71 ).
