Picture-in-Picture

The Picture-in-Picture display (PIP) is an option available on high-end TVs. By pressing a button on the remote control, a second picture, (coming from another connected source of video images,) will be displayed as a small inset in the corner of the main TV picture. The source could be a video recorder, a laserdisc player or a security camera. Because a video recorder has a built-in TV tuner, it is possible to display a second channel as a PIP-image. This enables you to watch one program, while keeping an eye on another. A PIP-image can be changed in size and moved about the screen. The inset picture can also be made the main picture and vice versa.


On-Screen Display (OSD)

By pressing the menu key on the remote control, a menu card appears on the screen. It enables you to make choices by simply entering a number, using the arrows or the +/- key. These choices cover TV installation, pre-defined channels, image and sound settings, and various special applications. This information can be retrieved on screen when watching a program. This digital feature is called OSD, On-Screen Display.
