1. General Description
The Z3-DM8107-SDI-RPS is a development system that allows encode and decode of HD video through SDI
inputs. It consists of a hardware package and software bundle designed to enable rapid development of
multimedia applications. The hardware consists of one Z3-DM8107-MOD System on Module card and one
Z3-DM8107-APP-10 board. The software bundle consists of the necessary components for developing
advanced multimedia, graphics, and DSP applications.
The Z3-DM8107-MOD is a compact OEM module which supports up to1080p60 H.264 encode/decode
1
in
streaming or storage mode. It is especially suited for power-sensitive applications requiring a single video
stream. These applications include broadcast video encoding and decoding, video surveillance and
security, industrial digital video recorders (DVRs), and medical video. The Z3-DM8107-MOD provides access
to most of the interface signals available from the DM8107 processor. Figure 1 below shows the Z3-
DM8107-MOD System on Module:

An application board, the Z3-DM8107-APP-10, is included with the Z3-DM8107-SDI-RPS.This application
board uses the I/O expansion capability of the Z3-DM8107-MOD to implement additional functions not
present in the base module. The Z3-DM8107-APP-10 application board has 2 SDI inputs, 1 SDI output, 1 set
of L/R analog stereo audio inputs, 1 HDMI output, and 4 LEDs for status. Figure 2 below shows an image of
a Z3-DM8107-APP-10 application board:
A Linux-based SDK, additional design services, and support are available from Z3 Technology. Please

4. Untarring and Building the Sample Code
4.1 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
4.2 Making the Directories and Running the Make Script
The software provided will allow you to re-create the pre-installed software of the Z3-DM8107-SDI-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-dm810x
Copy the released tar archive to that directory (note: the name may slightly vary).
# cp SW-4R2-00167-01_DM8107-SDI-RPS-20140311.tar.bz2 /home/z3/z3-dm810x
Untar the archive (name of tar file may slightly vary):
# tar -xvjf SW-4R2-00167-01_DM8107-SDI-RPS-20140311.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-centaurus-dm810x_sdi_rps-20140311
# ./makeall
Note: Building can take around 30-40 minutes. You will also need to type in the sudo password a few
