3. Untarring 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-VI-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 (note: the name may slightly vary).
# cp SW-7R1-00063-01_DM8169-MC-VI-RPS-20130827.tar.bz2 /home/z3/z3-netra-rdk
Untar the archive (name of tar file may slightly vary):
# tar -xvjf SW-7R1-00063-01_DM8169-MC-VI-RPS-20130827.tar.bz2
Note: Untarring takes 5 to 10 minutes.
Then go into the directory just created and run the build script (directory name may slightly vary):
# cd z3-netra-RDK-20130826
# ./makeall

10
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.
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.

4. Code Overview
4.1 Directory Structure
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-DM816X-VI-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.
4.1.1 The z3apps/rdk directory
There are 3 main subdirectories: rdk_demo, z3_mcfw_api, and z3 (Note: Source code is available for
customers that have licensed RPS-SRC. For licensees of RPS, binaries of the applications are available).
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

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
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 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
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 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=SDI1 dst=rtp://192.168.0.6:5004 size=1280x720 audio=off
will start an encode from SDI1 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
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 demo is demo.c. The top-level files for the command line interfaces
are demo_mcsenc.c and demo_mcsdec.c.

5. Running the Encode Demo
This section gives step-by-step instructions on taking the Z3-DM816X-VI-RPS and using it to stream 1080p or
1080i video to VLC running on your PC. In addition to the Z3-DM816X-VI-RPS, an HD source with HDMI
output and a PC are required.
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 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 Board

(3) Take the HDMI cable connected to the monitor and connect it to HDMI In of the board.
(4) Connect the Ethernet of the board to either your PC or a hub your PC is connected to.
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 correct 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 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 RPS 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. Note that the first 2 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 3 parts of the IP address would have to be
the same.
After you are done, make note of the address you set your PC 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). 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 System Setup menu should come up:
(10) Click on the “CH1” tab
(11) You should see the Channel 1 configuration tab (Figure 6). In this tab, change Video Resolution to

“1920x1080”, 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).
(12) Click “start” (note: The demo may have already started as it will automatically start in 30 seconds if
a valid input is detected. If that occurs, just click “stop” first). The status should change from
“IDLE” or “STOPPED” to “RUNNING” (Figure 6). If status is “POLLING” that means a valid HDMI input
was not detected in HDMI In.
