5.0 UNTARRING AND BUILDING THE SAMPLE CODE
5.1 Preparing the Linux Environment
Prior to building the Z3 sample code, certain modules are required. In Ubuntu 10.x or later, the
following command can be used to get the required modules:
sudo apt-get install bison flex mtd-utils liblzo2-dev uuid-dev zlib1g-dev
libpcre3-dev autoconf autoconf-archive automake automake1.9 automake1.9-doc
libtool libtool-doc
In Fedora, the command would be:
sudo yum install bison flex mtd-utils mtd-utils-ubi lzo-devel libuuid-devel
pcre-devel automake automake17 automake14 autoconf libtool
If you are running a 64-bit OS, it may be necessary to install some 32-bit libraries for the cross-compiling
toolchain. You can determine whether your OS is 64-bit by using the “uname –p” command. A 64-bit OS
will return “x86_64,” while a 32-bit OS will return “i386”, “i586”, or “i686”.
For 64-bit Ubuntu, you can get the necessary libraries by typing:
# sudo apt-get install ia32-libs
For 64-bit Fedora, you can type:
# sudo yum install glibc.i686
5.2 Making the Directories and Running the Make Script
The software provided will allow you to re-create the pre-installed software of the DM8169-4CH-RPS
starting from the included source code.
On a PC running Linux, create a directory where the released materials are going to be located:
# mkdir /home/z3/z3-netra-rdk
Copy the released tar archive to that directory:
# cp SW-7R1-00330-01_DM8169-4K-RPS-20141124.tar.bz2 /home/z3/z3-netra-rdk
Untar the archive:
# tar -xvjf SW-7R1-00251-01_DM8169-4CH-RPS-20140728.tar.bz2
Note: Untarring could take 5 to 10 minutes.
Then go into the directory just created and run the build script:
# cd z3-netra-4K-RPS-20141124
# ./makeall
*Note: Building can take around 30-40 minutes. You will also need to type in the sudo password a few
times towards the end of the build.

Z3 Technology, LLC ♦100 N. 8th St. STE 250 ♦Lincoln, NE 68508-1369 USA ♦+1.402.323.0702
The outcome of the build process should be newly created image files in the images directory. You can
confirm this by doing the following:
# cd images
# ls -alt
The result should be something like the following. Note that actual filenames, dates, and times will
differ:

6.0 CODE OVERVIEW
Once you have untarred the code, you will see the following top-level directories:
build-tools Config files and scripts for building the codebase
dvr-rdk A modified version of the TI RDK code
factory Factory testing scripts (the user can disregard these)
filesys The base filesystem for release
kernels Kernel code for release
sysapps Various supporting applications
toolchain The ARM toolchain for building the codebase
u-boot u-boot code for release
z3apps Z3 demo application code and scripts
The Z3 demo code that comes with the Z3-DM8169-4K-RPS is run from the run.sh script in dvr-
rdk/dvr_rdk/bin/ti816x. This code calls the z3_dvr_rdk_demo_mcfw_api.out binary, which initializes and
runs the encoder. This binary is built from the dvr-rdk directory. The code for the binary resides in
z3apps/rdk/rdk_demo. The z3apps/rdk directory is described in more detail in the next section.
6.1 The z3apps/rdk directory
There are 3 main subdirectories: rdk_demo, z3_mcfw_api, and z3
6.1.1 rdk_demo
This directory contains the code for the various modes that Z3’s boards are able to run in. The
encoder setup is done in demo_vcap_vdis.c. The decoder setup is done in demo_vdec_vdis.c. The
passthrough setup is done in demo_vcap_vdis.c.
The file demo_rtptx.c is responsible for setting the output mode of the encoder. Output to file,
RTP, and MPEG2-TS are handled here.
The file demo_mcsenc.c contains the implementation of the command line interface. This can be
run using the following command:
# source /opt/mcsenc/mcsenc.sh
6.1.2 z3_mcfw_api
This directory contains a modified version of the TI mcfw API (found in dvr-
rdk/dvr_rdk/mcfw/src_linux/mcfw_api) that is tailored to work with Z3’s hardware and use-cases.
The link setup code for Z3’s demos can be found in the usecases directory. The use-case code is
called from ti_vsys.c in the same directory.

Z3 Technology, LLC ♦100 N. 8th St. STE 250 ♦Lincoln, NE 68508-1369 USA ♦+1.402.323.0702
6.1.3 z3
This directory contains the base code for rtp tx and rx, as well as the base code for audio capture
and output.
6.2 Z3 Application Overview
6.2.1 Application Names and Locations
For encode, there are 2 binaries in the sample code. The first is a menu-based demo (this is what
comes up in the serial terminal when the board is powered on). The second is a command line
interface that is more flexible and easier to use from a programming standpoint. The web-based
interface uses the command line interface extensively.
The menu-based demo binary can be found at:
/opt/dvr_rdk/ti816x/bin/z3_dvr_rdk_demo_mcfw_api.out
The command line interface binary can be found at:
/opt/dvr_rdk/ti816x/bin/mcfw_mcsenc
6.2.2 Application Options and Arguments
The menu-based demo uses an .ini file. This .ini file is built in the script run.sh and stored in
/tmp/encode.ini.
Once called with the .ini file, the menu-based demo presents to the user a menu of demos. Most .ini
files are geared towards a specific demo. The easiest way to get a valid .ini file is to run the script
with the settings you want and then copy the generated .ini out of /tmp and save it.
The command line interface for the encoder is set up by running:
# source /opt/mcsenc/mcsenc.sh
This will present you with an "=" prompt. You can then enter commands to encode. For example:
= encode instance=1 source=HDMI1 dst=rtp://192.168.0.6:5004 audio=off
will start an encode from HDMI1 streaming to 192.168.0.6 at port 5004. You can find an example of
using this in a script at:
$PRJROOT/dvr-rdk/runz3demo.sh
6.2.3 Application Source Code
Application source code is available under a separate license agreement. For customers that have
licensed it, the application source code can be found mainly in:
z3apps/rdk/rdk_demo
The top-level file for the menu-driven application is demo.c. The top-level files for the command
line interfaces are demo_mcsenc.c and demo_mcsdec.c.

7.0 RUNNING THE Z3-DM8169-4K-RPS ENCODER
To encode 4K video, complete the following steps:
7.1 Prepare the 4K Source
(1) Set the video source to 4K2K30 (3840x2160 at 30fps) and connect an HDMI 1.4 cable to it.
-29.97, 25, and 23.98fps also supported.
7.2 Connect the Z3-DM8169-4K-RPS
For these steps, please refer to Figure 6.
(2) Connect the supplied 2.5mm serial cable and NULL modem adapter to your PC.
(3) Take the HDMI 1.4 cable from step (1) and connect it to HDMI In on the Z3-DM8169-4K-RPS.
(4) Connect an Ethernet cable to the Ethernet jack on the Z3-DM8169-4K-RPS. Connect the other end of
the Ethernet cable directly to a PC or to a hub connected to a PC. You will use this PC to control
the Z3-DM8169-4K-RPS.
(5) Take a USB 3.0 drive that the encoder will write to and connect it to USB1 (the top USB port). USB
3.0 is recommended to ensure that it is fast enough to write the encoded data.
*Note: The drive must be formatted in either FAT32, NTFS, VFAT, EXT3, or EXT4 format. exFAT is
not currently supported.

7.3 Set Up the Terminal Window
(6) If you are running from a Windows PC, run TeraTerm. Select “Setup – Serial Port” and set the
following:
Port: Whichever serial port the port is connected to
Baud Rate / Data / Parity / Stop: 115200 / 8-bit / None / 1-bit
Flow Control: None
(7) 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>, and then “Exit”
7.4 Power on the Board
(8) Connect the 12V power supply.
(9) Turn on the power switch.
(10) You should see the board booting up within the terminal window. After about one minute, you will
see the Main Menu in the serial console:

7.5 Ensure Your PC has a Proper IP address
(11) Note the IP address and netmask shown in the menu (default value is 192.168.81.68 and
255.255.0.0).
(12) To be able to communicate with the Z3-DM8169-4K-RPS, the PC that you are communicating from
needs to have at least the same first 2 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). Ensure that this
is the case. If necessary, use the “P” and “N” options in the RPS menu to modify the address /
network mask of the board to conform to your network. Note that the first 2 parts being the same
are based on a netmask of 255.255.0.0. If netmask were 255.255.255.0, then the first 3 parts of
the IP address would have to be the same.
7.6 Run the Web Interface to Configure and Start Encode
(13) In your PC, run a web browser (for best results, Z3 recommends FireFox or Chrome). In this
browser, type the IP address of the board noted in step (9) (for example, if the default value is
used, it would be http://192.168.81.68). After about 3 seconds, the System Setup menu should
come up:
(14) Confirm that the mode is “Encoder Ultra HD.” If it is not, select “Encoder UltraHD” as the operating
mode in the lower right corner.

(15) Click on the CH1 tab to bring up the encoder settings:
7.7 Configure the Encoder to Write to File and Start the Encoder
(16) Set “Output Format” to “TSFILE”
(17) In “Dest Address” type in the name of the file to save to
(example: /media/sda1/test_4k2k.ts to save to file “test_4k2k.ts” on USB1)
(18) Check if the encoder has already autostarted (the encoder will autostart if it senses a valid input
and 20 seconds have elapsed since the Z3-DM8169-4K-RPS came up). If it has autostarted, click on
“stop.” The status will then change to “STOPPED.”
(19) Click on “start” to begin encoding. You will see LED2 start to flash. This indicates the encoder is
running.
