PVI Virtual Media Services

[1] Founded in 1990 as Princeton Electronic Billboard,[2] PVI Virtual Media Services was a wholly owned subsidiary of Cablevision Systems Corporation (NYSE: CVC)[3] with a research and operations facility in Lawrenceville, NJ before being acquired by ESPN[4] in December, 2010.

[11][12] Brown Williams had been a senior manager at David Sarnoff Research Center (now part of SRI International) and knew that they had developed advanced, vision based pattern recognition and tracking technology for various U.S. defense agencies.

Roy Rosser and a small team of programmers and consultants spent the next 18 months re-engineering the system, inventing novel methods and algorithms of pattern recognition and tracking[13][14] so that the match making could work to the standards required by TV broadcasters under the variable conditions of a real game using the computing power then available.

[16] SciDel developed a technology to insert electronic virtual advertisements into live and taped televised sporting events, which it sold as a managed service in the European market.

[17] On April 16, 2004, PVI aired Strike Zone, High Home Cam, and Ball Tracer on Fox's prime time broadcast of a New York Yankees–Boston Red Sox game.
