1.0 GENERAL INFORMATION
1.1 Preface
The Z3-DME-01 Digital Media Encoder is a cost-optimized, compact 186mm x 123mm system that supports
H.264 High Profile encode up to 1080p at 30 frames per second. This solution works in multiple applications
such as low-cost broadcast encoders, low-bandwidth video security, satellite uplink, remote monitoring and
industrial applications. The Z3-DME-01 provides immediate access to multi-format HD video, integrated
system peripherals and production-qualified codecs.
The Z3-DME-01 offers multi-format, multi-channel HD video up to 1080p30. The Z3-DME-01 features HD
performance, compact size, and low latency while still having less power consumption than a PC-based
encoder platform.

5.0 GETTING STARTED AND RUNNING THE Z3-DME-01
For these steps, you will need: a computer, a 1080p30/1080i video source, a Z3-DME-01, a 12V
power supply, an HDMI Cable, an HDMI to SDI Converter, a coaxial cable and at least one Ethernet
cable.
5.1 Setting up the Video 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 an HDMI cable from the HD Source to a monitor
-Set the HD Source to 1080p30 or 1080i output
-Select and begin playback of the content
If you see playback on the monitor, you’ve confirmed the source works. Now move the HDMI
cable from the monitor to “HDMI In” on the HDMI to SDI converter box.
(2) Connect the coaxial cable from “SDI Out” on the converter box to the Z3-DME-01 “SD/HDI
Input” port (see Figure 4).
5.2 Connecting and powering up the Z3-DME-01
(3) Connect an Ethernet cable to “Ethernet” on the Z3-DME-01 (see Figure 4). Connect the other
end of the Ethernet cable directly to a PC. You will use this PC to control the Z3-DME-01 and
to decode the output stream.
(4) Connect the 12V power supply to “+12VDC” (see Figure 4).

(5) Power on the Z3-DME-01:
(6) Wait around one minute for the “Status” LED to light up.
5.3 Finding the Z3-DME-01 on the Network using ZFinder
(7) Make sure your Windows PC is connected to the same network which the Z3-DME-01 is
connected to.
(8) 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-01 appears:

(1) Turn on PWR
(2) Status lights up after around 1 minute

(9) Click on the Z3-DME-01 entry in the window to select it. This will cause the “Edit Device”,
“Open Device” and “Flash Leds” boxes to activate:
Figure 7 ZFinder with Z3-DME-01 Selected
(10) By clicking “Edit Device”, you can change the Name, IP Address, Netmask, and Gateway
address of the Z3-DME-01. You can also flash the LEDs on the Z3-DME-01 board by clicking
“Flash Leds” (useful if there are multiple Z3-DME-01’s connected). Click on “Open Device.” An
Internet browser window is opened (default browser used is Firefox) and the Web GUI appears:

(11) Now that you have reached the GUI, you are ready to modify the settings for the encode that
you want to do. Make sure “Video Source” is “SDI” and “Output Interface” is
“ASI+Ethernet(CBR).” Change “Output Format” to “MPEG-2 TS”, and make sure “Dest IP
Address” is “225.1.2.3” and “Dest Port” is 8888:

(3) Make sure
“Output
Format” is
“MPEG-2 TS”
(5) Set “Dest Port” to 8888
(2) Make sure “Output
Interface” is set to
“ASI+Ethernet”
(1) Make sure “Video Source”
is “SDI”
(4) Make sure “Dest IP
Address” is 225.1.2.3

(12) The encoder may have already started. If it has, click on “Stop Encoder”. The status should
then change to “Stopped”. Then click on “Start Encoder”. Once you do this, the status will
change. If the encoder hadn’t started already, simply click on “Start Encoder” and observe
the status change:

5.5 Opening a VLC Client to Receive the Encoded Stream
(13) Run VLC on your PC (version used in testing at Z3: 2.05. Any version after 1.1 should be ok.)
(14) Select Media –Open Network Stream. In the box, type “udp://@225.1.2.3:8888”.
(15) Press “Enter”.
(16) You should now see video streaming from VLC.

5.6 Streaming RTP
Once you have UDP streaming running, it is relatively simple to change to RTP streaming. All that
is needed are a change of settings and an SDP file (an example file is provided with the software
release from Z3). To stream using RTP, do the following steps:
(17) Click on “Stop Encoder”to stop the current encoding session.
(18) Change “Output Interface” from “ASI+Ethernet (CBR)” to “Ethernet (VBR)” (see Figure 9).
This is necessary because RTP is a variable bit rate format and is not supported over ASI.
(19) Change “Output Format” from “MPEG-2 TS” to “RTP” (see Figure 9)(Note: Do not select
“MPEG-TS over RTP”).
(20) Confirm that “Dest Port” (see Figure 9) is 8888 (this will be important for the VLC
configuration).
(21) Click “Start Encoder” to start the encoding session.
(22) Copy the “z3-dm368.sdp” file received from Z3 to your PC.
(23) Open VLC. Select “Media – Open File” and select the “z3-dm368.sdp” file you just copied.
(24) You should then see RTP video streaming on VLC:

5.7 Using DHCP
This release also supports using DHCP to acquire an IP address at boot-up:
(25) Click the “Use DHCP” check box in the Web GUI. Once it is checked, you will see that the
values of Local IP Address, Local Netmask, and Default Gateway will gray out:
(26) Click on “Save User”. Wait for “Saved All to User” message to appear:
(27) Power off
(1) Check “use
DHCP”
(2) Values gray out
(1) Click “Load User”
(2) Wait for “Saved all to User” to appear in status

the Z3-DME-01.
(28) Power back on the Z3-DME-01. Wait about one minute for the “ready” LED to turn on.
(29) Click “Refresh” on ZFinder. The Z3-DME-01 should appear with a new IP address based on
what it received through DHCP:
(30) As you did previously, select the Z3-DME-01 row and then click “Open Device.” A browser will
then appear with the GUI, this time using the new IP address:

5.8 Dynamically changing bit rate / frame rate
It is possible to change two parameters in the middle of an encoding session:
(1) Video Bit rate
(2) Frame Decimation
To change these, simply enter the new desired value and then click the “Start Encoder” button.
The web page will respond with the following message:
Status: Changed rate
The video stream will then continue interrupted with the new parameter.
5.9 Tuning for Latency
For latency, the key parameter to work with is Video Burst Size.
Video Burst Size defines the number of milliseconds of buffering the encoder has to work with. The
higher this value, the more buffering it has to work with and the more time it has to “smooth
things out” for challenging content. However, a higher value also causes latency to increase
accordingly. To minimize latency, this value should be set to the lowest possible value. The
lowest value Z3 recommends is 150.
The figure below shows the suggested values for Video Burst Size for three common use cases:
Maximum Delay
Case 1: Highest Quality, Highest Latency
2000
Case 2: Good Quality, Standard Latency
1000
Case 3: Normal Quality, Lowest Latency
150

5.10 Streaming RTMP
The Z3-DME-01 also supports streaming RTMP to servers such as Wowza and ustream. The steps for
doing so are as follows:
(1) Follow steps (1)-(9) earlier in this section to connect the DME-01 for encode and bring up the
Web GUI.
(2) If using Wowza, install the Wowza server on a PC on your network (for details on configuring
Wowza, please see Appendix A).
(3) In the Encoder Web GUI, set “Output Interface” to “Ethernet (VBR)”.
(4) Set “Output Format” to “RTMP”. This will cause “Dest IP Address” and “Dest Path” to appear.
(5) In “Dest IP Address”, type the IP address of the PC with the Wowza server (in this example, it is
“10.1.10.251.”).
(6) In “Dest Path”, type “/live/1080”.
(7) Set the resolution to “1080i” (or preferred resolution you want to stream to Wowza).
After finishing steps (1)-(7), the GUI should look like the following:

(8) Click “Start Encoder” to begin RTMP stream.
Now you are ready to view the content in Wowza.
(1) Set to “Ethernet (VBR)”
(2) Set to “RTMP”
(3) Set to IP Address of Wowza Server
(4) Set to “/live/1080”
(5) Set to “1080i”
