media extender - Computer Definition
(2) 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. A media extender differs from a general-purpose network because it guarantees bandwidth for the media types it supports and its audio/video port connectors. For example, a wireless HDMI extender enables high-definition video to be transmitted from an HDMI source to multiple HDMI destinations.
