and Media Center Extender
A device that transmits audio and video data from one location to one or more receivers. Either wired or wireless, it is designed to increase the distance between source and destination.

For example, a wireless HDMI extender enables high-definition video to be transmitted from an HDMI source to multiple HDMI destinations.
