PS3 to PSP
Interactivity between Sony's home video game consoles and handheld video game console is traced back as far as 2006, prior to the PlayStation 3's launch, when journalists noticed a PlayStation Portable icon, with the title "Remote Play", on pre-release versions of their PS3.[6] The functionality was officially revealed just prior to the PS3's launch in October 2006, at Sony's "Gamer's Day" event, where Sony demonstrated the ability to transfer the PS3's output to a PSP instead of a television, through showing downloaded PlayStation games and movie films being transmitted to a PSP's screen and speakers.[7] Sony announced that all original PlayStation games would support the feature, but they had to be digital, not disc-based, media from the PS3's internal harddrive.[8][9] This later changed by the end of 2007, when a firmware update made it so any original PlayStation game was compatible with Remote Play, even disc-based ones.[10]
Despite Sony's early emphasis on Remote Play and original PlayStation game support, it was used very sparingly between the PS3 and PSP, with very few PS3 titles allowing for its use. The feature was even removed from several titles before their final release, most notably Gran Turismo HD and Formula One Championship Edition.[11] Most titles were small PlayStation Network-only titles. The 2007 PS3 title Lair was notable for being one of the few original, physical Blu-ray disc releases to work between the PS3 and PSP.
PS3 to PS Vita
In late 2011, just prior to the launch of the PlayStation Vita, video game website Eurogamer published a rumor stating that a firmware update for the PS3 would provide Remote Play compatibility for all PS3 games when using Remote Play between a PS3 and Vita.[12] The premise seemed plausible, with websites reporting that Sony had shown working demonstrations of the concept prior to the rumor at the Tokyo Game Show, showing LittleBigPlanet 2 and Killzone 3 supporting the feature.[13][14] Despite this, the rumor was declared false by Sony, who said that the feature had to be implemented on the software side by developers on an individual basis, not on a hardware level.[15]
PS3 to Vita Remote Play went on to be rarely implemented as well. It retained any games supported by PS3 to PSP Remote Play support, including all original PlayStation games, but was again rarely used by actual PS3 games. Only a few games supported it, namely HD Remasters
PS4 to PS Vita
In June 2013, Sony announced that all PlayStation 4 games would be compatible with Remote Play with the PS Vita, with the exception of games which conceptually would not work, such as ones that heavily revolve around PlayStation Eye use.[17] Otherwise, contrary to PS3 to PS Vita Remote Play, PS4 to PS Vita Remote Play is designed on a hardware level, meaning that all games are automatically compatible, and it is only up to developers to make sure the controls adapt well to being played on a Vita instead of a DualShock 4.[17] This iteration of Remote Play was developed by Gaikai,[19] who also developed PlayStation Now.[20] Remote Play on the updated PlayStation Vita 2000 was shown at Tokyo Game Show in 2013.[21]
PlayStation Portal
In November 2023, Sony released the PlayStation Portal, a handheld gaming accessory for the PlayStation 5. The PlayStation Portal includes an 8-inch LCD HD screen and "all of the buttons and features of a DualSense controller".[22]
Other uses
PS4 firmware update 1.70 introduced full remote play functionality for the PlayStation TV, allowing users to play PS4 games in a separate room or house, on a television set with a PS TV device remotely connected to the PS4.[23][24]
Remote Play with the PS4 is available for Android smartphones and tablet computers running Android 5.0 Lollipop or later, and requires a DualShock 4 in order to play games. The service was made available on 28 October 2014, exclusively on Sony's Xperia Z3 series phones,[25][26] and was expanded to Sony's older Z2 series a month later.[27] In October 2019, support was expanded to all Android smartphones with the release of PS4 system software 7.00.[28]
