PlayStation Vita
The PlayStation Vita (and the PlayStation TV which uses the same system software as the PlayStation Vita) supports a feature called Remote Play with Sony's home video game consoles such as the PlayStation 3 and the PlayStation 4. It allows the PlayStation 3 and PlayStation 4 to transmit its video and audio output to a PlayStation Vita. However, unlike Remote Play between the PlayStation Vita and the PlayStation 4 which is well-integrated, Remote Play between the PlayStation Vita and the PlayStation 3 is only supported by a "select" few PS3 titles and results were often laggy. In a similar vein, the PlayStation Vita can be used as a second screen device for the PS4 (and for PS3, but only supported by very few games such as Class of Heroes 2G) for streaming content directly from the console to the PlayStation Vita.
