InstaPrevue™ technology from Silicon Image makes TVs and AV
receivers easier to use by taking the guesswork out of switching between
HDMI® sources. Instead of having to remember whether the Blu-ray
player is "HDMI-1" or "HDMI-4," the user gets a live picture-in-picture (PiP)
video preview of each connected device, making it simple and intuitive to switch
between the cable box, the disc player, the gaming console, and any other
HDMI-connected source. Just click on a video preview and go.
