RUNNING THE ENCODER
This section gives step-by-step instructions on using the SBE264-DVR-13 to encode 1080p or 1080i video from
an HDMI source to a VLC media player on your PC. In addition to the SBE264-DVR-13, an HD source with non-
HDCP HDMI output and a PC with VLC media player are required.
*Note: Actual version numbers for your Z3 product may differ from those pictured in this document.
5.1 Set up the Video Source
(1) Select an HD source with HDMI non-HDCP output (in Z3’s testing, the Brite-View BV-5005HD is used).
-Power on the HD Source.
-Connect HDMI to a monitor.

____________________________________________________________________________________
Z3 Technology, LLC ♦100 N. 8th St. STE 250 ♦Lincoln, NE 68508-1369 USA ♦+1.402.323.0702
-Set the HD Source to 1080p or 1080i output.
-Select content you would like to stream.
If you see playback on the monitor, you’ve confirmed the source works.
5.2 Connect the SBE264-DVR-13
Connect the supplied 2.5 mm serial cable and gender changer to the serial console of the single
board encoder and to your PC.
Take the HDMI cable connected to the monitor and now connect it to HDMI In on the board.
Connect an Ethernet cable to the board and either your PC or hub on the same network as your PC.
5.3 Set up the Terminal Window
If you are running from a Windows PC, we recommend running TeraTerm for serial configuration and
monitoring. Select “Setup – Serial Port” and use the following settings:
Port: Whichever serial port the port is connected to
Baud Rate: 115200
Data: 8-bit
Parity: None
Stop: 1-bit
Flow Control: None

Z3 Technology, LLC ♦100 N. 8th St. STE 250 ♦Lincoln, NE 68508-1369 USA ♦+1.402.323.0702
If you are running from Linux, type:
# sudo minicom –s
And then configure by doing the following:
-Select “Serial Port Setup”
-Ensure the right Serial Device is specified (typically “/dev/ttyUSB0”)
-Set option E (“Bps/Par/Bits”) to 115200 8N1
-Press <return>
-Select “Exit”
5.4 Power on the Board
Connect the 5V 2A power supply and turn on the power switch.
If all is configured properly, you will see the board booting up within the terminal window. After
about one to two minutes, you will see the Main Menu.
Note the local IP address and netmask (typically 192.168.81.68 and 255.255.0.0). This is the IP
address of the board. You will need this later to access the HTTP-based user interface.
5.5 Ensure your PC has a Proper IP Address
To be able to communicate with the board, the PC that you are communicating from needs to have
the same first two parts of the IP address. For example, if the board has an IP address of
192.168.81.68, your PC would need to have an address of 192.168.x.y, where x.y is anything but
81.68 (and not conflicting with whatever is on your current network, of course). Verify that this is
the case. If necessary, use the “P” and “N” options to modify the address/network of the board to
conform to your network. Note that the first two parts being the same are based on a value of
netmask of 255.255.0.0. If netmask were 255.255.255.0, then the first three parts of the IP address
would have to be the same.
After you are done, make note of the address you set. This will be important in the streaming step.
5.6 Configure Channel 1 for HDMI Encode
In your PC, run a web browser (for best results, FireFox or Chrome are recommended). In this
browser, type the IP address of the board noted in step (6) (by default, this value would be
http://192.168.81.68 when the unit is first received). After about three seconds, the HTTP-based
graphical user interface (GUI) will appear at the System Setup tab.

Z3 Technology, LLC ♦100 N. 8th St. STE 250 ♦Lincoln, NE 68508-1369 USA ♦+1.402.323.0702
Click on the “CH1” tab.
In the Channel 1 configuration tab, verify the “Video Source” is set to “HDMI”.
Change the “Video Resolution” is set to “Follow Input” or “1920x1080”.
Set “Output Format” to “UDP”.
You can set the “Dest Address” to:
(a) the IP address of your PC that will be running the VLC media player (in the pictured
example, 192.168.0.6)
(b) or to a multicast address (An example multicast address would be “225.1.2.3”. If you are
on a shared network, check with your Network Administrator.)
Make note of the “Dest Port” (This will be “5004” by default).

5.7 Start Encoding
Click the “start” button at the bottom right corner of the screen.
*Note: It is possible that the system may have already started encoding (if valid input is connected, it
will autostart 20 seconds after booting up). You can tell this if the status in the lower right corner of
GUI says “RUNNING”. If the encoder is running, click “Stop”, wait for status to say “STOPPED”, and
then click “Start” for the newly entered settings to take effect.
If the status is “POLLING”, a valid HDMI input was not detected in HDMI In.
If you want to encode 1080p60, you must first change “Operating Mode” at the bottom right from
“Encode Interlaced/Progressive” to “Encode Single CH No Scale.” Note that, in “Encode Single CH
No Scale” mode, only the CH1 tab can be used.

5.8 Run VLC to View the UDP Stream
Run the VLC media player on your PC (version used in testing at Z3: 2.05)
Select Media –Open Network Stream. In the box, type “udp://@192.168.0.6:5004”, where
“192.168.0.6” matches the values of the computer IP address or multicast address entered for
“Dest Address” previously and “5004” is the value of “Dest Port” noted previously..
Press “Enter.”
You will now see your source video streaming to VLC.

5.9 Stream RTP/RTSP
Once you have UDP streaming running, it is relatively simple to change to RTP/RTSP streaming. You will
need to change one setting. To stream using RTP, complete the following steps:
In the CH1 configuration tab, click on “stop” to stop the current encoding session.
Change “Output Format” from “UDP” to “RTP/RTSP.”
Click on “start” to start the RTP/RTSP encoding session. At this point your settings should look like
the following:
Open VLC. Select “Media – Open Network Stream”.
In the “Open Media” box, type “rtsp://{IP Address}/z3-{ch #}{m}.mp4”, where {IP Address} is the IP
address of the SBE264-DVR-13, {ch #} is 1 for CH1, 2 for CH2, and 3 for CH3, and {m} is added if a
multicast address is being streamed. For example, if the IP address of the SBE264-DVR-13 is
currently 192.168.81.3, encode is being done from CH1, and unicast streaming is being done, the
user would type in “rtsp://192.168.81.3/z3-1.mp4”.
Change to “RTP/RTSP”

*Note: To use the RTSP feature, VLC v2.1.5 or later is needed. If it is not possible to use a newer
version of VLC, it may be necessary to use SDP files instead of RTSP to stream RTP.
You will then see RTP video streaming on VLC.

5.10 Changing the Bitrate Dynamically
The SBE264-DVR-13 includes an “Update” button which allows you to change the bitrate without
stopping and restarting the encoder.
In VLC, click on “Tools” and select “Codec Information”. This brings up a window with four tabs.
Select the “Statistics” tab. In this tab, you can see the current video+audio bitrate:

5.11 Adjusting the UDP TS Rate
The SBE264-DVR-13 includes a parameter to adjust the TS rate independent of the video bitrate. This
can be found just below “PMT PID” when “UDP” is selected as the output format.
Normally, this value is set to 25% to 33% above the sum of the video and audio bitrate. For example, the
default value out of the factory is a value of 10Mbps, corresponding to 8Mbps for the video.
There are times, however, when it is desirable to make this value higher. For example, if the encoder
bitrate is very low (below 1Mbps), it is advisable to allow more leeway in the event there are some
challenging scenes to encode. An example follows:
Return to the “CH1” tab. In this tab, click “stop”. Then change “Video Resolution” to “720x480”,
“Video Bitrate” to “512K”, and “Output Format” to “UDP” (steps 1-6 in the figure below):
Once you select UDP, “TS RATE” should appear with the default value of 10000K. Change this to
1000K (see step 5 above).
Click on “start” to start encoding (see step 6 above).
