The PlayStation 4 places an increased emphasis on social interaction and integration with other devices and services, including the ability to play games off-console on PlayStation Vita and other supported devices ("Remote Play"), the ability to stream gameplay online or to friends, with them controlling gameplay remotely ("Share Play"). The console's controller was also redesigned and improved over the PlayStation 3, with improved buttons and analog sticks, and an integrated touchpad among other changes. The console also supports HDR10 High-dynamic-range video and playback of 4K resolution multimedia.
