How It Works: StatCast is actually a combination of two systems. The first,
produced by TrackMan, tracks the trajectory of the ball as it is pitched, hit, and thrown. TrackMan's system is based on Doppler radar and will be discussed more in the next section. The second, which tracks the players, is the brainchild of ChyronHego and uses two camera arrays spaced about 15 meters apart to capture stereoscopic video. This allows StatCast to judge three-dimensional distance to a player similar to the human visual system. Not much is known yet about the process that allows them to produce videos like this, but the combination of video and radar is memory-intensive; terabytes of raw signals will be produced for every game.
How To Get It: Before the 2014 season, StatCast was installed in Citi Field, Miller Park, and Target Field; MLBAM plans to roll it out to the other 27 ballparks by the 2015 season. For now, the only things available are some tantalizing video clips, but MLBAM CEO Bob Bowman said in a March interview, "The goal is to put the product out this year, then get to all 30 parks, then release the data in unvarnished form in 2015."
