PIP or picture in picture is a feature accessed in the television or similar other devices and requires separate, independent tuners or signal sources in order to supply the large and small picture. It is often used to watch one program while waiting for the another to start or the advertisement to finish. The PIP videos can be displayed in a range of customizable sizes with pinching gestures and can be dragged in all the four corners of the screen. In addition the PIP can also be dragged off the screen to see more of the display. The PIP works on any video as well as Apple's own native app. The app should include the Apple's tools for the background playback.
The PIP window appears on a 240/135 DP in one of the screen corners and is displayed on the top of the contents.
