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 5.1 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:

Streaming
5.1 Stream content to device
If you are using a Bright Sign 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. 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, it’s free. For more information
go to www.meldtech.com/support
Setting up the PC (IP address scheme assumes MT300 factory default settings)
•
•
•
In a Command prompt 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)
in a Command prompt window type “ping 192.168.1.193” (This operation sets up
an ARP entry on the PC)
If properly working the ping command will return “Request timed out” message.
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
cannot reply. If it says not connected, check physical connection and power
MT300.
Make sure ARP table registry is correct
• In a Command prompt window type type “Arp –a”

Using 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. (Some examples are provided below.) You could also use VLC
with a command line interface via Command prompt window for streaming; it is easier
than the GUI interface.
Creating a batch file is a good way to easily and simply broadcast demo content. Of
course file locations and stream names may change depending on your computer
configuration.
Sample Batch files
Streaming an DVD
What you are doing: Sending DVD stream to 192.168.1.193, port=5002
*** 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
Streaming an MPEG2 file
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 2: Broadcast a few HD files in a loop ***

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 and the TV tuner must be tuned to the correct channel to receive the
transmitted content. Refer to the following steps:
6.2
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 Command prompt 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 Command prompt window Type “ping tvws.spectrumbridge.com”

If the ping reply message times out without a reply, investigate potential
network or internet problems.
Check Ethernet connection to the MT300
• in a Command prompt 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
• In a Command prompt window type “Arp –a”
• You should see the device
Internet Address: 192.168.1.193
Note: If 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.) Use the second
mac addess printed on the label which is located on the bottom of the MT300 case.
ARP command to set ARP TABLE
• in a Command prompt window type “arp -s 192.168.1.193 00-02-03-04-05-06”
6.3
Tuning the TV Receiver
If you are confident that you have correctly set up the media server and the transmit light
on the MT300 is illuminated you may need to repeat the channel scan on you TV
receiver.
• Select “antenna in” on your TV. Make sure you have an antenna attached. Using
the keypad, type in the preferred channel selected during the device setup.
Example: 23.1. If the TV does not allow you to directly type in a channel,
execute a channel scan and then type your preferred channel. Example 23.1
