  • Patent number: 8705799
    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.

  • Patent number: 7787058
    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. The count is monitored and if the count matches a predetermined value, then a trigger is generated based on the predetermined value and the playlist. 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.

When a receive signal to be selected by the tuning circuit is not the CS television broadcast signal, the AFC process is performed with the frequency in the turning circuit adjusted in units of a fine frequency adjustment value for reception of a CS.With this arrangement, it is made possible to increase the tuning accuracy when tuning in to the CS sound broadcast signal, while the time required for tuning is shortened and the waiting time reduced when tuning in to the CS television broadcast signal and, thereby, both the requirements for reception of the CS sound broadcast signal and for reception of the CS television signal can be satisfied.
