Picture-In-Picture, or PIP as it is commonly abbreviated, is a feature included with some Samsung LCD HDTVs that enables viewing two inputs at the same time. When the feature is turned on, the current source becomes the main picture, and the analog coaxial TV source becomes the Picture-In-Picture at the top-right of the screen. To make the Picture-In-Picture feature on your Samsung LCD HDTV work, you need two different inputs connected to it, such as HDMI/Coaxial, Component/Coaxial or VGA/Coaxial. Writer Bio
