Abstract: A system for enhancing the television presentation of an object that can display the object even if the object is not visible to a camera. The system determines whether the object is visible to the camera broadcasting the event. If the object is not visible to the camera, the video image captured by the camera is edited to show the object, not show the object or enhance the video in a different manner. The object is placed in the captured video image at the position the object would be in the camera's field of view if there was no barrier between the object and the camera.

Abstract: Although sensors are typically registered before the live event, a sensor's location, orientation and/or field of view can be altered during the event. A system for re-registering a sensor during a live event allows for the determination that a sensor is not properly registered. If such a determination is made, the system accumulates valid data during the live event. The valid data is compared to the data from the improperly registered sensor in order to determine the amount of error. The variables that define the sensor's registration are changed to reduce the error.
