The Z3-HE1080-APP-01 is an application board design for rapid prototyping of the Z3-HE1080-MOD-xx and is
included in the Z3-HE1080-RPS. This application board uses the I/O expansion capability of the module to
implement additional functions not present in the module itself. This application board has one HDMI input,
one composite input and one 3G-SDI input as well as ports for Gigabit Ethernet, USB, Micro SD and RS-232
serial.
The Z3-HE1080-RPS software is based on the Linux OS. The kit comes with all of the low-level resources such
as the Linux kernel, u-boot, tool chain and starter file system pre-integrated and configured. The software
bundle also contains tools to allow the development of high-level applications using hardware-accelerated
video processing. Those customers that license the optional source code package can also receive source
code for Z3’s demonstration applications, providing an ideal starting point for custom applications.
Z3 Technology can provide services to customize the software applications to a customer’s specification. For
design services or additional support, please contact Z3 at www.Z3technology.com or
[e-mail].

QUICK START GUIDE2.0
2.1 If You Have Received a System from Z3 with the Software Preloaded
To start working with the encoder, you can go straight to Section 7.0, “RUNNING THE ENCODER,” on
page 13. This section describes how to quickly stream UDP, RTP or RTSP from the RPS.
2.2 If You Already Have a System from Z3 and Need to Update the Firmware
There are several options for updating the firmware on your RPS by following the instructions in Section
9.0: “RUNNING THE CODE YOU BUILT ON THE BOARD”, on page 33.
2.3 If You are Ready to Start Development
Details on how to untar and build the code can be found in Section 5.0: “ UNTARRING AND BUILDING
THE SAMPLE CODE,” on page 11. A brief overview of the code itself can be found in Section 6.0: “CODE
OVERVIEW,” on page 12.
Details on how to set up your system to access the code you have built can be found in Section 9.0:
“RUNNING THE CODE YOU BUILT ON THE BOARD”, on page 33.

RUNNING THE ENCODER7.0
This section gives step-by-step instructions on HEVC/H.265 encoding with the Z3-HE1080-RPS and streaming
1080p or 1080i video from an HDMI video source to a PC media player. In addition to the Z3-HE1080-RPS, you
will need the following:
A non- HDCP source with HDMI output
A PC with VLC media player
The SDP file provided with your Z3 software release (see your customer support server account)
7.1 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.
-Set the HD Source to 1080p or 1080i output.
-If you are using a media player, select content you would like to stream.
If you see playback on the monitor, you’ve confirmed the source works.
7.2 Connect the Encoder
Connect the supplied 2.5 mm serial cable and gender changer to the serial console of the application(1)
board and to your PC. (A USB to Serial converter may be needed. If so, the FTDI UC232R-10
(Digikey part #768-1014-ND) is recommended.)
Take the HDMI cable connected to the monitor and now connect it to HDMI In on the board.(2)
Connect an Ethernet cable to the board and a switch or router on the same network as your PC or(3)
directly to your PC.

Z3 Technology, LLC ♦100 N. 8th St. STE 250 ♦Lincoln, NE 68508-1369 USA ♦+1.402.323.0702
7.3 Set up the Terminal Window
If you are running from a Windows PC, we recommend running TeraTerm for serial configuration and(4)
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
If you are running from Linux, type:(5)
# 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”
7.4 Power on the Board
Connect the 5V 2A power supply.(6)
Turn on the power switch. If all is configured properly, you will see the board booting up within the(7)
terminal window. After 20-30 seconds, you will see the RPS Main Menu.
Note the local IP address and netmask (192.168.0.120 and 255.255.0.0 by default). This is the IP address
of the board. You will need this later to access the HTTP-based user interface.

____________________________________________________________________________________
Z3 Technology, LLC ♦100 N. 8th St. STE 250 ♦Lincoln, NE 68508-1369 USA ♦+1.402.323.0702
7.5 Verify your PC has the 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 192.168.0.120,
your PC would need to have an address of 192.168.x.y, where x.y is anything but 0.120 (and not
conflicting with what is on your current network).
Ensure that this is the case. If necessary, use the “P” and “N” options to modify the address/network (8)
of the board to conform to your network.
*Note: The first two parts need to be the same based on the netmask set to 255.255.0.0. If
netmask were 255.255.255.0, for example, then the first three parts of the IP address would have
to be the same.
After you are done, make note of the address your PC is set to. This will be important in the(9)
streaming step.

7.6 Run the HTTP-based User Interface to Configure Channel 1 for Streaming UDP
The following actions can be completed in either the serial interface or an HTTP-based interface run on
a web browser. For ease of use, the HTTP-based interface is described.
Open an Internet browser window on your PC (for best results, FireFox or Chrome are(10)
recommended) and enter the IP address of the RPS (192.168.0.120 by default) into the URL text
box. The HTTP-based graphical user interface (GUI) appears at the CH1 tab.
Note: Settings in the user interface cannot be changed if the unit is currently encoding.
Click the red “Stop” button at the bottom of any screen to stop any current encoding.(11)
At the CH1 tab, verify the “Video Source” is set to “HDMI” using the dropdown menu.(12)
Change “Output Resolution” to “1920x1080” or “Follow Input”.(13)
Select the codec you would like to use for your encoding. Both H.265/HEVC and H.264/AVC are(14)
supported. In the pictured example, verify “Video Codec” is set to “H265(HEVC)”.
Set “Output Format” to “UDP”.(15)
You can set “Dest Address” to:(16)
(a) the IP address of your PC that will be running 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.)
Also make note of the value of “Dest Port” (8600 by default).(17)
Click the green “Start” button.

7.7 Run VLC to View the UDP Stream
Run the VLC media player on your PC (version used in testing at Z3: 2.1.5).(1)
Select Media –Open Network Stream. In the box, type “udp://@192.168.0.6:8600”, where (2)
“192.168.0.6” matches the values of the computer IP address or multicast address entered for
“Dest Address” previously and “8600”is the value of “Dest Port” noted previously.
Press “Enter” or click “Play.”(19)

7.9 Run VLC to View the RTP Stream
An SDP file is needed to view an RTP stream from the Z3-HE108-RPS in the VLC media player. You can
find this on the USB drive provided with your system.
Open VLC media player.(29)
Select “Media – Open File”. (30)
In the file type dropdown menu, select “All Files (*)”.(31)
Find and select the SDP file corresponding to the video and audio codec you selected previously.(32)
(a) H265(HEVC) video + AACHE audio: use the SDP file entitled “z3-netra_h265_aache.sdp”
(b) H265(HEVC) video + AACHEv2 audio: use the SDP file entitled “z3-
netra_h265_aachev2.sdp”
(c) H264(AVC) + no audio: use the SDP file entitled “z3-netra_h264.sdp”
Click “Open”.(33)
You will now see video streaming to VLC.(34)
