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. In 2014, the definition was expanded to include the use of PlayStation TV, the Sony Xperia Z1, Z2 or Z3 smartphones, and PlayStation Now.
