The Sony Corporation will announce Thursday that it has signed a deal to bring Major League Baseball’s live streaming service to PlayStation3 video game consoles.

By the end of the week, PlayStation owners will be able to sign up with MLB.TV to watch out-of-market baseball games transmitted over the Internet. It is the latest in a series of digital distribution deals recently announced by sports franchises.

Sony said the baseball deal signified its repositioning of the PlayStation console as a hub for digital entertainment. Peter Dille, the senior vice president for the PlayStation Network at Sony Computer Entertainment America, said in an interview on Wednesday, “This is more than just a game console. This is a device that is redefining how content is being delivered to the living room.”

Microsoft portrays its Xbox 360 console in a similar way.

The PlayStation deal is MLB’s first with a video game maker, giving Sony a leg up for the time being. Users of the PlayStation Network online service will be able to gain access to the existing MLB.TV package, which includes hundreds of baseball games — excluding local team games and others that are broadcast on TV — for an annual fee. There is a revenue split associated with the deal, but Sony would not specify the terms.
