Operator Manual
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.

Installation
4.1
Front/Rear Panel Interface
It is recommended the MT300 be installed and located in a secure area such as a network
closet or operations center. The antenna may be mounted remotely in cases where such
locations do not result in the desired area of RF coverage.
4.2
Setting up MT300 for first time use
To configure the device for the first time:
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 MT300 (e.g., 192.168.1.100). This can be done as a
direct connection or via a router, please reference figure 1 and figure 2.
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.

Figure 2 – Alternative setup for device configuration
Connect the antenna provided to the RF port located on the backside 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)
Set up
With your browser to go: http://192.168.1.194/ and complete the device registration form.
All fields are required for successful registration. This will enable the FCC certified
database to authenticate the system and provide white space channels that are available
for use in your location. Reference the examples shown below.
Professional installation tools and procedures for determining location must be used to
accurately determine the location within +/- 50 m accuracy.

Using your Pico Broadcaster
Station Identification Signal
The FCC requires that Fixed TVBDs transmit identifying information sufficient to
identify the device and its geographic coordinates. The MT300 ID signal is transmitted
as an ATSC compliant signal that can be received by any Digital TV receiver. The
following information is required in the ID message:
Transmitter Location: 34.34567 N, 119.32487 W
FCC ID: OKVMT300
Manufacturer: MELD Technology
Following the steps below the operator is required to stream the identification
information for transmission no less than once a day.
Step 1: Create a file containing the required identification identified above.
•
Using a video editing system such as Micro Soft Movie Maker or others, create
a Title Screen containing 3 lines with the following information:
Transmitter Location: 34.34567 N, 119.32487 W
FCC ID: OKVMT300
Manufacturer: MELD Technology
The location information above is an example only. The location will be unique
for each device installation, refer to section 4.2 of this manual to obtain the registration
location information for your device
Step 2: Save your file as an MPEG2 standard format file
•
Using the video editor render the Title Screen as a 3 second MPEG2 formatted
file.
Step 3: Stream the content to the MT300
•
Following the instructions in section 5.3 of this manual, stream the MPEG2 file to
the MT300. Verify the information is displayed on at least one of the TV
receivers tuned to the transmitting channel as shown in the example below:

Stream it
If you are using a BrightSign box you’ll need to refer to their manual.
If you are using a PC you can use the VLC media player as an example. The application
can be found here: http://www.videolan.org/vlc/index.html. If you are unfamiliar with
VLC media player follow the instructions below and in section 5.3 of this manual.
What you are doing: Sending an MPEG2 transport stream to 192.168.1.193, port=5002
How to do it: Creating a batch file is a good way to easily and simply broadcast demo
content.
*** Sample Batch file 1: Broadcasts a DVD ***
Note: It is very easy and convenient to stream DVDs using VLC. (DVDs are a great
source for TS material). We suggest you start with this…
Using notepad editor to create BroadcastDVD.bat
"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" dvdsimple://D:\
:sout=#rtp{dst=192.168.1.193,port=5002,mux=ts} :no-sout-rtp-sap :no-sout-standard-sap
:ttl=1
Of course file locations and stream names may change depending on your computer
configuration.
For more information go to www.meldtech.com/support
NOTE: When not streaming content to your MT300, turn off your transmitter by
removing power to the device.
Tune It

TV receiver: Select “antenna in” on your TV. Make sure you have an antenna attached.
Go to channel 23.1. If the TV does not allow you to directly type in a channel, do a
channel scan and then type 23.1.

Trouble Shooting
5.1
Hardware Setup
If the MT300 is not transmitting the supplied content, the device may be unable to
contact the database or the media server may not be configured correctly. You must
connect the MT300 to an internet accessible network in order to access the internet for
database services. The media providing streaming content to the MT300 must be
configured correctly. Refer to the following steps:
5.2
Set up and test Ethernet connection.
If the “power” LED is not illuminated on the MT300 front panel:
• Verify the power connection is securely plug in on the back panel
• Verify the A/C power outlet that power supply is plugged into.
Check the static address setting on the PC or media delivering the content.
• In a DOS window type “IPCONFIG” to view the PC IP address.
Note: When using direct connection, make sure the PC and MT300 are in the same IP
domain: Set the computers IP Address to a static address on the same subnet as the
MT300 (e.g., 192.168.1.100)
If the transmit or “On Air” light is not illuminated on the front panel, verify the MT300
network connection to the TVWS database service.

Connect a PC to the same local network connection that the MT300 is using
In a DOS window Type “ping www.tvws.spectrumbridge.com”
Verify a successful reply from the TVWS service:
ping tvws.spectrumbridge.com
Pinging tvws.spectrumbridge.com [204.51.99.33] with 32 bytes of data:
Reply from 204.51.99.33: bytes=32 time=27ms TTL=242
Check Ethernet connection to the MT300
• in a DOS window type “ping 192.168.1.193”
• If properly working the ping command will return “Request timed out” as shown
in Fig 1.0. This means the Ping command properly saw the MT300 but the
MT300 did not respond back, which is to be expected as the MT300 is a one-way
streamer and can not reply. If it says not connected, check physical connection
and power MT300.
Make sure ARP table registry is correct
• 2.1) in a DOS window type type “Arp –a”
•
You should see the device
Internet Address: 192.168.1.193
Physical Address: some value
Note: If for you do NOT see the device you’ll need to force the ARP table to map to the
IP address to the physical address of the MT300 (i.e. 00 02 03 04 05 06.)
ARP command to set ARP TABLE

in a DOS window type “arp -s 192.168.1.193 00-02-03-04-05-06”
Stream content to device
We are currently using VLC for streaming (www.videolan.org). This configuration has
been tested using version 1.0.5 and 1.1.11. We suggest you download the latest version,
its free .
VLC Streamer Command line.
Easy streaming… If you find the navigating the VLC GUI a little tedious we suggest we
set up some batch files. (So examples are provided below.) You could also use VLC
with a command line interface via DOS window for streaming, it is easier than the GUI
interface, Sample Command line code;
Sample Batch files.
Creating a batch file is a good way to easily and simply broadcast demo content.
