![]() ![]() In July 1995, PVI had successfully used its L-VIS (Live Video Insertion System) match moving technology to broadcast virtual advertising behind the home plate on a local broadcast of a Trenton Thunder baseball game. The rivalry between PVI and Sportvision began with a collaboration. Four years later, SportsMEDIA introduced a third version during NBC coverage of a Notre Dame game. A few weeks later, on Thanksgiving Day in 1998, Princeton Video Image (PVI) aired its version of the virtual yellow down line on a CBS broadcast of a Pittsburgh Steelers– Detroit Lions game. The 1st & Ten line was first broadcast by Sportvision, a private company, during ESPN's coverage of a Cincinnati Bengals- Baltimore Ravens game on September 27, 1998. ESPN's NFL coordinating producer, Fred Gaudelli, was tasked with overseeing an implementation for his network. In 1998, ESPN programmer Gary Morgenstern and others revived the idea. At the time, both decided the broadcast industry was not ready to use Crain's invention. Crain, who presented the concept to Roone Arledge and Roger Goodman of ABC News and Sports and to the CBS Technology Center. The idea of creating an on-field marker to help TV viewers identify first down distances was conceived and patented in 1978 by David W. The system makes use of a combination of motion sensors mounted on the broadcast cameras to record what they are viewing, and/or the use of match moving computer graphics technology and an enhanced version of chroma key or "green screen" technology. In extreme weather situations, an entire virtual field with yard and boundary markers can be projected onto the field in order to allow league officials, broadcasters and viewers some way to follow action when all field markings are obscured by snow, fog or mud. Lines can also be projected to show other types of field position, including markings for the red zone and the optimum maximum distance for a placekicker's statistical field goal range. Some football broadcasts change the color of the line from yellow to red on 4th down, or show a second computer-generated line (usually blue in color) that marks the line of scrimmage. However, PVI's competing system is more accurately named L-VIS, for Live Video Insertion System. The line is not physically present on the field and is seen only by the television audience.ġst & Ten is sometimes used generically to refer to the class of systems capable of adding first down lines and similar visual elements and not just the Sportvision system. Developed by Sportvision and PVI Virtual Media Services, it is best known for generating and displaying a yellow first down line over a live broadcast of a football game-making it easier for viewers to follow play on the field. The 1st and Ten line displays the yard line needed for a first down during an ESPN Sunday Night Football broadcast.ġst & Ten is a computer system that augments televised coverage of American football by inserting graphical elements on the field of play as if they were physically present the inserted element stays fixed within the coordinates of the playing field and obeys the visual rules of foreground objects occluding background objects.
