Abstract: Apparatus (1) for generating a video stream includes a communication interface (10) for receiving as input; one or more images of a first input sequence (L) of images representative of a first view of an input stereoscopic stream (VIN); one or more images of a second input sequence (R) of images, each corresponding to a respective image of the first input sequence (L), the images of the second input sequence (R) being representative of a second view of the input stereoscopic stream (VIN); one or more maps which allow, starting from one or more images of the first input sequence (L), to substantially rebuild corresponding images of the second input sequence (R); one or more maps which allow, starting from one or more images of the second input sequence (R), to substantially rebuild corresponding images of the first input sequence (L).
