1 Overview

The Digital Media Adapter (DMA3.1L) delivers video and audio over 5GHz wireless channels using

Amedia Networks’ WiViTM wireless networking technology. It enables a wireless connection between

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.

9 System Status

1. Upon power on, the Power LED will be on.

2. After system boot up (up to 10 seconds on the Wireless AV Sender), the Link LED will blink

indicating acquisition mode.

3. When communication is established between the Sender and Receiver, the Link LED will stay on

indicating tracking mode.

4. In tracking mode, video and audio input signal at the Wireless AV Sender is sent wirelessly to the

video and audio output at the Wireless AV Receiver.

10 Functional Specifications

10.1 Audio and Video Inputs at the Wireless AV Sender

The DMA3.1L system transmits audio and video signals from the Wireless AV Sender to the Wireless

AV Receiver, by encoding and multiplexing the signals according to MPEG-2 standards. The Wireless

AV Sender includes video and audio inputs.

10.1.1 Video Inputs

a) The Wireless AV Sender supports the following video inputs:

-Composite Video input

-S-Video input



Confidential & Proprietary

Amedia Networks, Inc. DMA3.1L User Manual

b) The video input is selected by automatic detection of a video signal in one of the inputs. If two inputs

become active simultaneously, the order of precedence is: S-video, Composite video.

c) Video standards supported on video inputs: NTSC and PAL.

d) The system supports NTSC Closed Caption signals. The CC signals are accepted at the video inputs

and transferred to the video outputs.

10.1.2 Audio Inputs

The Wireless AV Sender supports an analog stereo audio input, consisting of Left and Right audio

channels.

10.2 Audio and Video Outputs

The Wireless AV Receiver decodes the MPEG-2 stream, de-multiplexes the audio and video signals, and

outputs the signals to the TV. The Wireless AV Receiver includes video and audio outputs.

10.2.1 Video Outputs

The Wireless AV Receiver supports two video outputs:

-Composite Video output

-S-Video output.

b) Video output standard (NTSC/PAL) is according to video input.

c) Video standards supported on video outputs: NTSC and PAL.

d) Support of Closed Caption signals.

10.2.2 Audio Outputs

The Wireless AV Receiver supports an analog stereo audio output, consisting of Left and Right audio

channels.

10.3 IR Function

The IR function enables the user to control the video source devices such as DVD and STB, even when

the TV and the video source devices are not in the same room. The user can use the original remote

control unit of the video source device by pointing the remote control at an IR receiver located at the

Wireless AV Receiver. The IR receiver at the Wireless AV Receiver receives the IR signal, digitizes it,

and sends it over the air to the Wireless AV Sender, which re-generates the IR transmission towards the

video source device’s IR receiver.

10.4 NTSC/PAL Auto-Detect

The Wireless AV Sender automatically detects the NTSC/PAL system of the active input video source.

The Wireless AV Receiver will output the same system correspondingly. Video source and TV must be

of the same system.

10.5 LED and Switch

The DMA3.1L supports LED outputs and switch/button inputs as follows:

No. Name Description

1 Power LED On: power on

2 Link LED Blinking: acquisition mode (searching for Wireless AV

Sender/Receiver)

Solid on: track mode (found Wireless AV Sender/Receiver,

link established)

3 Pairing LED On during pairing procedure

4 Pairing switch Initiates pairing procedure

10.6 System Security

The communication is authenticated and the media stream is encrypted, to assure for protection of

copyrighted material.
