1.0 GENERAL DESCRIPTION
The Z3-DME-03 is a cost-optimized, compact 118 x 121 mm system that allows encode of HD video (up to
1080p60) through SDI or HDMI input, and encode of SD video through a composite input. It allows users to
quickly take video from any of those three sources and stream them to the web or internal clients / PCs via
UDP, RTP, or RTMP. This solution is ideal for applications such as low-cost broadcast encoders, low-
bandwidth video security, satellite uplink, remote monitoring and industrial applications. The Z3-DME-03
provides immediate access to multi-format HD video, integrated system peripherals and production-
qualified codecs.
The Z3-DME-03 features HD performance, compact size, and low latency while still having less power
consumption than a PC-based encoder platform. Figure 1 below shows the Z3-DME-03:

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 go straight to Section 6.0, “RUNNING THE ENCODER,” on
page 11. 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.
Encoding from SDI is described. For encoding from HDMI or composite, a special step of creating a CH2
to encode from is needed. This is described in detail on page 28.
Details on streaming RTMP and also on using the “Encode 1 to 3 Ch” mode (which allows one source to
be encoded 3 different ways, as long as the total processing involved fits within the constraints of Z3-
DME-03 performance) can be found in Section 7.0, “STREAMING RTMP IN THREE DIFFERENT
RESOLUTIONS,” on page 33. There are additional notes on successfully configuring Wowza in “APPENDIX
A: Configuring the Wowza Server for RTMP,” 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 8.2
“Making a Firmware Update”on page 39.

6.0 RUNNING THE ENCODER
This section gives step-by-step instructions on taking the Z3-DME-03 and using it to stream 1080p or 1080i
video to VLC running on your PC. In addition to the Z3-DME-03, an HD source with SDI output and a PC are
required. Encoding with an HDMI or a composite source is described later in Section 6.11 on page 28.
6.1 Set up the HD Source
Select an HD source with SDI output.
-Power on the HD Source
-Connect SDI 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.
6.2 Connect and Power Up the Z3-DME-03
Connect the SDI source to “SDI In” on the front of the Z3-DME-03:
Connect an Ethernet cable connected through a hub or router to a PC to “Ethernet” on the back of
the Z3-DME-03 (see above).
Connect the 5V power supply and turn on the switch.
Wait around 1 minute.

6.3 Find the Z3-DME-03 using ZFinder
Make sure your Windows PC is connected to the same network in which the Z3-DME-03 is connected.
Run the “ZFinder” PC Utility on your Windows PC. The ZFinder window appears. ZFinder does a scan
of the network and lists the location of all Z3 systems connected to the network. In this case, the
Z3-DME-03 appears:
Figure 7 ZFinder with Z3-DME-03 Listed
Click on the Z3-DME-03 entry in the window to select it. This will cause the “Edit Device”, “Open
Device” and “Flash LEDs” boxes to activate:
Figure 8 ZFinder with Z3-DME-03 Selected
Note: Since there are no LEDs on the Z3-DME-03, clicking “Flash LEDs” will have no effect.

Click on “Open Device.” An Internet browser window is opened (default browser used is Firefox)
and the Web GUI appears at the System Setup tab:
Click on the “CH1” tab.
6.4 Configure CH1 and Encode
At the CH1 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).

*Note:If you want to encode 1080p60, you must first change “Operating Mode” at the bottom right
from “Encode Interlaced/Progressive” to “Encode Single CH No Scale.” Note that, in “Encode Single
CH No Scale” mode, only CH1 can be used.

The encoder may have already started (after 20 seconds, the encoder will automatically try to
start). If it has, click on “stop” near the bottom of the screen. The status should then change to
“STOPPED”. Then click on “start”. Once you do this, the status will change to “RUNNING.” If the
encoder hadn’t started already, simply click on “start” and observe the status change:

6.5 Run VLC to View Stream
Run VLC on your PC (version used in testing at Z3: 2.1.5)
Select Media –Open Network Stream. In the box, type “udp://@192.168.0.6:5004”, where
“192.168.0.6” is the IP address of your PC, and 5004 is the value of “Dest Port” noted in step (11).
Press “Enter.”
You should now see video streaming to VLC:

6.6 Streaming RTP
Once you have UDP streaming, it is relatively simple to change to RTP streaming. A few parameter
changes are all that is needed. To stream using RTP, complete the following steps:
In the CH1 configuration tab, click on “stop” to stop the current encoding session.
Change “Output Format” from “UDP” to “RTP.”
Click on “start” to start the RTP encoding session. At this point your settings should look like the
following:
(1) Change to “RTP”

Open VLC. Select “Media – Open Network Stream”.
In the “Open Media” box, type “rtsp://{IP Address}/z3-{ch #}{m}.mp4”, where {IP Address} is the
IP address of the Z3-DME-03, {ch #} is 1 for CH1, 2 for CH2, and 3 for CH3, and {m} is added if a
multicast address is being streamed. For example, if the IP address of the Z3-DME-03 is the
default value of 192.168.81.7, encode is being done from CH1, and unicast streaming is being
done, the user would type in “rtsp://192.168.81.7/z3-1.mp4”:
.
*Note: VLC version 2.1.5 or later is needed for RTSP support.
You should then see RTP video streaming on VLC:

6.7 Changing the Bitrate Dynamically
The Z3-DME-03 includes an “Update” button which allows you to change the bitrate without stopping
and restarting the encoder. To use this feature, complete the following steps:
In VLC, click on “Tools” and select “Codec Information.” This brings up a window with four tabs.
Select the “Statistics” tab. In this tab, you can see the current video + audio bitrate:
In the CH1 screen, change the bit rate from “8000K” to “2000K” and click “update”:
(1) Change bitrate to 2000K

You should see the quality of the picture in VLC change and the video bitrate drop:
If you click on the status page and click “Refresh,” you will also see the updated bitrate
reflected:
The parameter “Frame Rate Divider” can also be updated dynamically using the “update”
button. All other parameters require a stop and then start to change.
