1.0 GENERAL DESCRIPTION
The Z3-DM8168-RPS is a set of hardware boards, software tools, and applications designed to enable the
rapid development of media-centric applications. It contains one Z3-DM8168-MOD-2x System on Module
card, one Z3-DM8168-APP-0x application board, as well as bundled software with all of the necessary
components for the user to quickly develop their own advanced multimedia, graphics, and DSP
applications.
The Z3-DM816x-MOD-2x is a compact OEM module which supports H.264 High Profile encode/decode at up
to two channels of 1080p at 60 fps (frames per second). The Z3-DM8168-MOD-2x features a unique
expansion interface comprised of five high density connectors providing access to most of the interface
signals available from the DM8168 processor. Figure 1 below shows the Z3-DM8168-MOD-2x System on

The Z3-DM8168-APP-0x application board includes two HDMI 1080p60 inputs, two component inputs, and
two composite inputs. Figure 1 below shows the Z3-DM8168-APP-2x and its inputs/outputs.
Figure 2 Z3-DM8168-APP-0x
The Z3-DM8168-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. There is
no need to port or integrate OS functions, media functions etc. The software bundle also contains tools to
allow the development of high-level applications using hardware-accelerated video processing, DSP, and
graphics. 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.
Additional design services and support are available from Z³ Technology. Please contact Z3 at
www.Z3technology.com or e-mail at [e-mail].
*Note: Z3 does not warrant modules that are operated outside the specified scope of operation per Texas
Instruments datasheets or errata for the DM816x processors. This includes but is not limited to the SATA2
interface. Per specifications from Texas Instruments, only SATA2 drives are supported.

2.0 QUICK START GUIDE
2.1 If You Have Received a System from Z3 with the Software Preloaded
To start working with the encoder, you can skip to Section 7.0, “RUNNING THE ENCODER,”
on page 19. This section describes how to quickly generate a UDP or RTP stream to VLC, how to change
bitrate dynamically, how to adjust the UDP TS rate, how to tune for latency, and how to use DHCP.
Section 8.0, “ STREAMING RTMP” on page 38 describes streaming to Wowza using RTMP. Section 9.0,
“RUNNING THE DECODER” on page 42 describes how to use the decoder. If you have any questions about
any GUI parameters you can refer to Section 12.0, “SUMMARY OF OPTIONS,” on page 52.
2.2 If You Already Have a System from Z3 and Need to Update the Firmware
You can update the firmware via the web GUI interface by following the instructions in Section 10.1
“Method 1: Updating the Image File ”on page 45.
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 12. A brief overview of the code itself can be found in Section 6.0, “CODE
OVERVIEW”, on page 14. Details on how to set up your system to access the code you have built can be
found in Section 10.2, “Method 2: Running Your Code through TFTP/NFS”, on page 47.
