1 Overview

The Digital Media Adapter (DMA3.1L) delivers video and audio over 5GHz wireless channels using
Amedia Networks' WiVi
video/audio sources (for example, DVD, VCR, PVR, STB, and PC) and a video/audio display (TV, flat
panel or video monitor).
The IR relay function enables the user to control the Video Source devices from a remote TV. The user
can use the original remote control of the video source devices (such as DVD) by pointing the remote
control at an IR receiver located at the Wireless AV Receiver. The IR signals are conveyed by the
wireless network to the Wireless AV Sender.
