Abstract: The path and/or position of an object is tracked using two or more cameras which run asynchronously so there is need to provide a common timing signal to each camera. Captured images are analyzed to detect a position of the object in the image. Equations of motion for the object are then solved based on the detected positions and a transformation which relates the detected positions to a desired coordinate system in which the path is to be described. The position of an object can also be determined from a position which meets a distance metric relative to lines of position from three or more images. The images can be enhanced to depict the path and/or position of the object as a graphical element. Further, statistics such as maximum object speed and distance traveled can be obtained. Applications include tracking the position of a game object at a sports event.

Abstract: Information is provided to on-air personnel that is synchronized to a playlist executed by a broadcast automation system. A type is defined within a broadcast automation system and is associated with studio segments and non-studio segments that follow studio segments in a playlist. As the playlist is executed, the broadcast automation system provides a count until the next segment with the specified type.

Each trigger is associated with a particular action, such as the display of a message on certain display units. Once the trigger is generated, the action is performed. The invention can be used to automatically provide countdown information to on-camera personnel based on the playlist.
