MLB.TV to offer MultiView on Appletv this season

[Krgrecw]

The previous version of the MLB app for Apple TV allowed you to watch two games at once, but the secondary game was only shown in a smaller window off to the side of the “primary” game. To watch up to four games at the same time, you had to use the MLB.TV website.
This year, however, MLB is bringing proper Multiview support to the Apple TV as well as other platforms.

Does this work in the appletv app for playstation? Or will I have to have actual appletv?
