s are used as a backdrop for a set, on which video or computer generated imagery can be displayed in real-time. With careful adjustment and calibration, an OSVP set can be made to closely approximate the appearance of a real set or outdoor location. OSVP can be viewed as an application of extended reality. OSVP contrasts with virtual studio technology, in which a

backdrop surrounds the set, and the virtual surroundings are composited into the green screen plate downstream from the camera, in that in OSVP the virtual world surrounding the set is visible to the camera, actors, and crew, and objects on set are illuminated by light from the LED screen, creating realistic interactive lighting effects, and that the virtual background and foreground are captured directly in camera, complete with natural subtle cues like
