3Untarring and Building the Sample Code
3.1 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
3.2 Making the Directories and Running the Make Script
The software provided will allow you to re-create the pre-installed software of the Z3-DM816X-RPS RDK
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-6R2-00218-01_DM8168-MC-RPS-SRC-20140508.tar.bz2 /home/z3/z3-netra-rdk
Untar the archive:
# tar -xvjf SW-6R2-00218-01_DM8168-MC-RPS-SRC-20140508.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-DM8168-MC-RPS-SRC-20140508
# ./makeall
Note: Building can take around 30-40 minutes. You will also need to type in the sudo password a few

times toward the end of the build.
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.

4Code 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 sample application code and scripts
The Z3 sample application code that comes with the Z3-DM816X-RPS RDK 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.
4.1 The z3apps/rdk directory
There are three main subdirectories: rdk_demo, z3_mcfw_api, and z3
4.1.1 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

4.1.2 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 sample applications can be found in the usecases directory. The use-case code is
called from ti_vsys.c in the same directory.
4.1.3 z3
This directory contains the base code for RTP TX and RX, as well as the base code for audio capture and
output.
4.2 Z3 Application Overview
4.2.1 Application Names and Locations
For encode, there are two binaries in the sample code. The first is a menu-based sample application (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 sample application 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
On the decode side, there is a command line interface. The binary for this can be found at:
/opt/dvr_rdk/ti816x/bin/mcfw_mcsdec
4.2.2 Application Options and Arguments
The menu-based sample application 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 sample application presents to the user a menu of options.
Most .ini files are geared toward a specific option. 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 size=1280x720 audio=off
will start an encode from HDMI1 streaming to 192.168.0.6 at port 5004 scaled to 1280x720. You can find an
example of using this in a script at:
$PRJROOT/dvr-rdk/runz3demo.sh
The command line interface for the decoder is set up by running:
# source /opt/mcsdec/mcsdec.sh
This will present you with an "=" prompt. You can then enter commands to decode. For example:
= decode instance=1 source=rtp://192.168.0.6:5004 audio=on aport=hdmi
will start a decode from RTP from port 192.168.0.6 at port 5004 sending audio to HDMI.
4.2.3 Application Source Code
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.

5Running the Encoder
This section gives step-by-step instructions on taking the Z3-DM816X-RPS RDK and using it to stream 1080p
or 1080i video to VLC running on your PC.
5.1 Set up the HD 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
-Select content you would like to stream
5.2 Connect the Board
For these steps, please refer to Figure 4 and Figure 5.

(2) Connect the supplied 2.5mm serial cable and NULL modem adapter to your PC.
(3) Take the HDMI cable connected to the monitor and connect it to HDMI In 1 of the board.
(4) Connect the Ethernet
The next step is to set up a terminal to view the activity of the board …
5.3 Set up the Terminal Window
(5) 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: 115200
Data: 8-bit
Parity: None
Stop: 1-bit
Flow Control: None
(6) 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
(7) Connect the 12V power supply and turn on the switch. If all is configured properly, you should see the
board booting up within the terminal window. After about a minute, you will see the RPS Main Menu:

Note the local IP address and netmask (in this example, it is 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 web interface.

5.5 Ensure your PC has a proper IP address
(8) 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). Ensure 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, 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 you set it to. This will be important in the streaming
step.
5.6 Run the Web Interface to Configure CH1
(9) 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 (7) (for example, if the default value is used, it would
be http://192.168.81.68). After about 3 seconds, the control menu should come up:
(10) Click on the “CH1” tab
(11) You should see the Channel 1 configuration tab. In this tab, set “Output Format” to UDP and “Dest
Address” to the IP address of your PC (in this example, 192.168.0.6) Also make note of the value of
“Dest Port” (should be 5004 by default):
