1. Preface

This document provides operator information on how to set up the MT300 (Ethernet to

Broadcast) Pico Broadcaster. This device requires professional installation and the use of

tools and procedures for determining location, minimum power requirements.

2. IMPORTANT NOTICES

FCC Part 15 Information to the User

Caution: Changes or modifications not expressly approved by the party responsible for

compliance could void the user's authority to operate the equipment.

Note: This equipment has been tested and found to comply with the rules for TV bands

devices, pursuant to part 15 of the FCC rules. These rules are designed to provide

reasonable protection against harmful interference. This equipment generates uses and

can radiate radio frequency energy and, if not installed and used in accordance with the

instructions, may cause harmful interference to radio communications. If this equipment

does cause harmful interference to radio or television reception, which can be determined

by turning the equipment off and on, the user is encouraged to try to correct the

interference by one or more of the following measures:

(1) Reorient or relocate the receiving antenna.

(2) Increase the separation between the equipment and receiver.

(3) Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

(4) Consult the manufacturer, dealer or an experienced radio/TV technician for help.

RF Exposure

The radio described in this manual transmits RF energy. The concentrated energy

from the antenna may pose a health hazard. All antennas used with this radio must be

installed to provide a minimum separation from all persons of 40 cm (15.7 inches). The

above separation distance must be maintained at all times. More information can be

obtained from the FCC at the following website:

3. Introduction

The Meld Technology MT300 White Space radio must be professionally installed by a

trained installer. The installation must be in accordance with 47 CFR Part 15 Subpart H

and the instructions contained in this manual. Only the following components are

approved for use with the radio.

Power Supply: Stontronics 3A-401WP12

Antenna: U Tek Technology Co. EA-79X-1

3.1 Overview

MELD develops Pico Broadcast products for wirelessly distributing content to any DTV

ever made for the North American market using newly opened white space frequencies

and broadcast standard modulation methods.

The advantages of Personal Broadcast based solutions are:

Lower cost labor for installation, modification and support

Economy of scale using standard DTV receivers and components verses other

specialized non-standard receivers and communication methods.

MELD’s Pico Broadcaster sends live full HD content wirelessly to any number of DTVs

located in an unobstructed effective range of 360 feet, about the size of a football field.

No cabling or infrastructure equipment investment needed.

3.2 General Description

Figure 1 - Typical Setup for Device configuration and TVWS access

The MT300 is an easy to use Fixed TV bands device using a VSB modulator that is

designed to provide low-power transmission of a DTV compatible signal over a limited

area. It is designed to not interfere with licensed broadcast transmissions and complies

with the FCC CFR 47 Part 15 subpart H rules for TV Band devices. It is designed to

work with the tuner input of any Digital TV sold in North America. The MT300 is

designed to accept properly formatted MPEG2 transport streams from a local PC running

VLC or similar streaming software or a media server. The transmitted signal is compliant

with the tuner input of a Digital TV receiver.

3.4 Intellectual Property Warning

Some of the concepts described in this document are protected by appropriate patent

protections or other legal means. These areas are identified in the text as being

proprietary. For additional information on these subjects please contact MELD directly.

The device described herein is protected by US Patent #8,063,996, other patents pending.

3.5 System Architecture

MT-300 Pico Broadcaster

Operator Manual

The device has two IP address:

System Control CPU (default)

IP address: 192.168.1.194,

Gateway IP: 192.168.1.254

This address points to a web form used for user registration and setting up the

radio for FCC compliant operation including database access, and radio control

for operational parameters of the system, such as preferred channels and power.

Digital Modulator (default IP address)

IP: 192.168.1.193

Port: 5002

This IP address is for Transport Stream content going directly to the MELD

Digital Modulator for ATSC modulation.

3.6 Applications in Digital Signage

Pico Broadcast HD video distribution would enable airports, hotels, restaurants, bars,

schools, hospitals, professional, industrial applications to wirelessly send high-quality

video to any number of screens.

•Proven reliable: Used around the world; day in, day out, digital broadcast TV

reliably sends perfect clear HD images and sound over large areas.

•Completely wireless: No messy wires run, hide or trip over.

•No external box need: Signal is 100% compatible with any DTV ever built.

3.7 List of abbreviations

ATSC is the Government "Standard" for the Digital (RF) Broadcast Signal

8VSB is the name of the modulation standard used in ATSC Systems

SMPTE 310M is the electrical interface that carries MPEG-2 transport streams to 8VSB

modulators

PSIP is the name of the "table" structure that defines the structure and order of the MPEG

Streams in a valid broadcast stream ... per government regulations of USA

4. Installation

4.1 Front/Rear Panel Interface

Note: It is recommended the MT300 be installed and located in a secure area such as a

network closet or operations center. The device must be installed in a location that

provides a minimum separation from all persons and the antenna of 40 cm (15.7 inches).

Please refer to the RF Exposure warning on page 3.

4.2 Setting up the MT300 for first time use

Recommended Network Setup

Note: The MT300 needs internet access to be able to operate. The transmitter will not

be enabled until the device successfully registers with and receives a channel list from the

TV Bands database service.

Use of the setup in figure 1 and configuring the router LAN IP address set to

192.168.1.254 will allow access to the White Space database for registration. Set the

computers network setting in figure 1 to DHCP to acquire an address from the router.

Connect the antenna provided to the RF port located on the back panel of the device.

(Use of a different antenna other than the one provided is prohibited)

Plug-in the power supply adapter supplied with the MT300.

(Use of a different power supply other than the one provided is prohibited)

The MT300 is shipped with the factory default network settings below and are assumed

unchanged for the recommended network setup.

Factory Default Network Settings

Configuration Type - Static

IP Address - 192.168.1.194

Subnet Mask - 255.255.0.0

Gateway Address - 192.168.1.254

Primary DNS - 192.168.1.254

Secondary DNS –

Streaming IP Address – 192.168.1.193

Using your PC internet browser; type http://192.168.1.194 in the browser URL field to

access the device webpage interface. The device registration tab will be displayed. To

complete the device registration process, proceed to the Device Registration section

below for registering your device.

Custom Network Setup

Note: Currently, the MT300 only supports network subnets that are limited to

192.168.0.0.

The MT300 is shipped with the factory default network settings above. To change the

default network settings to be compatible with your network addressing scheme use the

MT-300 Pico Broadcaster

Operator Manual

setup in figure 1 or use the alternative setup below in figure 2 to change the MT300

network configuration.

If using the typical setup in figure 1, connect a PC and the MT300 to the router and set

the computers IP Address to a static IP address on the same subnet as the default settings

for the MT300 (e.g., 192.168.1.100). The LAN side of the router must be configured for

addresses within the 192.168.0.0 subnet.

Figure 2 – Alternative setup for device configuration

If using the alternative setup for device configuration, connect a PC to the MT300

Ethernet port and set the computers IP Address to a static IP address on the same subnet

as the default settings for the MT300 (e.g., 192.168.1.100).

Using your PC internet browser; type http://192.168.1.194 in the browser URL field to

access the device webpage interface. The registration tab will be displayed.
