EXPLORER
Configuration:
The system setup at the remote site consist of a DV camera connected through FireWire to a laptop
installed with the Streambox Portable ACT-L3 Encoder software. The laptop is connected to the
EXPLORER terminal through Ethernet. See system overview on picture 1 below:
Picture 1: System Overview
The tests were conducted mainly using the Streaming 256kbps. If using Standard Data service the
quality of the picture and voice will depend on the bandwidth available as this is a shared channel of
up to 492kbps. For important video broadcasts it is recommended to set the EXPLORER terminal to
use Streaming 256kbps and pay per minute.
First step is to configure the EXPLORER terminal by connecting a computer to the LAN interface.
After getting an IP address, open your web browser and type http://192.168.0.1/ Go to Settings >
Interfaces > LAN and select the Streaming (128 and 256) connections as Secondary profiles and
click on the Apply button at the bottom of the web page. Please refer to picture 2 on next page.

streaming connection.
Click on Administration and logon as Administrator (default User name: admin, Password: 1234).
This will give you access to the Traffic Flow Templates and filter configuration menus in the terminal.

Next step is to configure a UDP Traffic flow filter by typing 1 in the Filter 1 Eval.Prec.Index box and
17 in Protocol No. box. See picture 5 below:
This will force UDP traffic to pass through filter 1 which applies to Streaming 128 and Streaming 256.
Press Apply to store the new filter settings.

Streambox SBT35101D Configuration:
The Streambox SBT3-5101D decoder was configured with static IP behind a Linksys WRT54G router
which had port forwarding of port 1770 enabled towards the static IP of the Streambox SBT3-5101D
decoder.
Setting up the SBT3-5101D Decoder:
1) Connect analog audio/video output to the receiving equipment (f.ex a Television)
2) Connect an Ethernet cable from the encoder to the Internet, in the test case to the router
which again was connected to the Internet with an public IP address.
3) Connect a keyboard and mouse to the encoder.
4) Plug the mains power cable and switch ON the decoder and wait for it to finish boot up.
5) Configure the desired IP address for the decoder, by right-clicking “My Network Places”,
choose “Properties”, choose “Network Connections”, right-click “Onboard NIC”, choose
“Properties”, choose “Internet Protocol TCP/IP” and choose “Properties”. See example in
