NEW YORK – Taking a chance to review instant replay, Major League Baseball doubled the isolated cameras available for video reviews to 24 this year.MLB also arranged for high-frame rate cameras to stream directly to the new replay operations center and ballpark video rooms, and for MLB-controlled 4K cameras with zoom lenses to be installed at high locations behind home plate.A new replay hub about twice the size of the old one was constructed as part of the move of Major League Baseball and MLB Advanced Media to a combined office space in Manhattan, across the street from Radio City Music Hall.“We think that the product of all these items is going to result in a much more rapid review process, so that we’ll be getting video available much.
