Remote Play is a feature of Sony video game consoles that allows the PlayStation 3 and PlayStation 4 to transmit its video and audio output to a PlayStation Portable or PlayStation Vita. Similar functionality is provided on Nintendo's Wii U console, using the Off-TV Play function. This feature essentially allows compatible home console games to be played on the handheld. In 2014, the definition was expanded to include the use of PlayStation TV, Xperia smartphones and tablets (Z2 and later), and PlayStation Now. In 2016, it was expanded to Microsoft Windows PCs or Apple OS X Macs.
While seldom implemented on PS3, Remote Play is a mandatory feature on all PS4 games, except for games that utilize peripherals such as PlayStation Move.
Sony defined Remote Play as follows:
"Remote Play allows a PSP system to connect wirelessly to a PS3 system and transfers some functionality of the PS3 to the PSP system. With remote play, a PSP system may access files that are located on the PS3, as well as, play certain software titles..."
Sony later amended this definition to apply between the PlayStation 4 and PlayStation Vita as well. The premise of Off-TV Play on the Wii U is similar in concept, in how the video game console does all of the processing, but sends the image and sound straight to the Wii U GamePad's screen instead of a television screen. Similarly, in the case of Remote Play, the PlayStation 3 or PlayStation 4 do all of the processing, but transmit the image and sound to the PlayStation Portable or PlayStation Vita screens and speakers. While typically in reference to Sony consoles and handhelds, it has been used in different ways as well. In April 2010, a firmware update was released for the PS3 that allowed Remote Play between it and the Sony VAIO brand laptops as well.
