GETTING STARTED AND RUNNING THE Z3-MVPR-02
For this demonstration, you will need: a computer, a 1080p/1080i video source, a Z3-MVPR-02, a 12V power
supply, an HDMI cable, and at least 1 Ethernet cable.
To use and run the Z3-MVPR-02, please follow these steps:
Figure 4 Z3-MVPR-02 Demo Connections (Back)
5.1 Setting up the Video Source
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 1080p 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 Z3-MVPR-02 so that the cable runs from the HD Source to the Z3-MVPR-
02 (see Figure 4).
5.2 Connecting the Z3-MVPR-02
Connect an Ethernet cable to “Ethernet” on the Z3-MVPR-02 (see Figure 4). Connect the other end
of the Ethernet cable directly to a PC. You will use this PC to control the Z3-MVPR-02 and to
decode the output stream.
Connect the 12V power supply to “+12VDC” (see Figure 4).

5.3 Setting Up the Control PC
Set the PC IP address to one that can communicate with the Z3-MVPR-02
(a) Find the IP address of the Z3-MVPR-02. This can be found on the sticker on the bottom of the
Z3-MVPR-02. It should be 192.168.81.48.
(b) This means you need to set your PC to an IP address of 192.168.x.y, where x is any number
except 81 and y is any number except 48. Decide on an address (if any will do, we
recommend using 192.168.0.6).
(c) If you are using a Windows PC, bring up the IP Properties window of your PC. Though this may
vary depending on the version of Windows running on your PC, a typical sequence would be
something like:
(i) Find the “My Network Places” icon and double-click on it to bring up the “My Network
Places” window.
(ii) On the left side of that window, find “View Network Connections” and click on that.
(iii)This should bring up a list of connections. If the Ethernet cable is connected, one of
the connections that shows up is “Local Area Connection”. Right-click on this and
select “Properties”.

(iv) You should then see a “Local Area Connection Properties” Window. In this window,
one of the options is “Internet Protocol (TCP/IP)”. Select this and click on
“Properties”.

(d) At this point, you should now see the “Internet Protocol (TCP/IP) Properties” window (Figure
7). Click on “Use the following IP address” and set the IP Address to the value you
determined in step 4b (default value = 192.168.0.6). Also make sure the netmask is
“255.255.0.0”. Then click “Ok” to save these values.
(e) If you are using Linux, you can set up an alias network address to match what you need. An
example of a command doing this would be:
# sudo ifconfig eth0:0 192.168.0.6 netmask 255.255.0.0
Figure 7 Windows PC IP Address –Internet Protocol Window
Set to 192.168.0.6 (or whatever
value you decide on that begins
with 192.168.x.y and does not
equal 192.168.81.48)
Make sure the netmask is
set to “255.255.0.0”

5.4 Configuring the Z3-MVPR-02
Power on the Z3-MVPR-02.
Wait around 30 seconds to 1 minute for the LED “Status 1” to light up.
Open a web browser (FireFox or Chrome is recommended). Type in http://192.168.81.48. You
should then see the Z3-MVPR-02 Opening Menu (if you don’t see this, please see the
Troubleshooting section on page 30).

In the menu you should see 5 tabs:
System Setup: Set IP address of board, assign optional device name and password to board.
User Presets: Store current configuration as default or under a user-defined name.
Status: Check current system status (Note: Takes ~5 seconds to update)
CH1: Configure channel 1 encoder
CH2: Configure channel 2 encoder
Click on “CH1”. This will bring up the CH1 configuration menu. Change “Output Format” to “UDP”,
“Dest Address” to the IP address of your PC as determined in Step (4) (default value = 192.168.0.6).
Also note the value of “Dest Port” (default value 5004). This will be important when configuring
VLC to receive the encoded stream:

The encoder may have already started. If it has, click on “stop”. 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 to
“RUNNING”:

5.5 Opening a VLC Client to Receive the Encoded Stream
Run VLC on your PC (version used in testing at Z3: 2.05. Any version after 1.1 should be ok.)
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” from (9).
Press “Enter”.

5.6 Streaming RTP
Once you have UDP streaming, 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:
In the CH1 configuration tab, click on “stop” to stop the current encoding sessions.
Change “Output Format” from “UDP” to “RTP” (see Figure 10).
Confirm that “Dest Port” (see Figure 10) is 5004 (this will be important for the VLC configuration).
Copy the “z3-netra.sdp” file received from Z3 to your PC.
Open VLC. Select “Media – Open File” and select the “z3-netra.sdp” file you just copied.
You should then see RTP video streaming on VLC:

5.7 Encoding from Other Inputs
In addition to HDMI1, the Z3-MVPR-02 allows encode from a second HDMI channel, 2 component inputs,
and 2 composite inputs.
HDMI1, Component1, and Composite1 are all accessible from the “CH1” tab. HDMI2, Component2, and
Composite2 are all accessible from the “CH2” tab.
Most combinations are allowed. However, because of the way the hardware is configured within the
Z3-MVPR-02, two combinations are not allowed. For both of those combinations, an alternative is available.
Figure 15 below shows the combinations that are allowed and not allowed on the Z3-MVPR-02.

For Component inputs, Component1 is on the right side looking at the rear panel while Component2 is on
the left (see Figure 3). If a standard A/V cable is being used, the following mapping is used: red ->
red, white -> blue, yellow -> green (as shown in Figure 16).
For Composite inputs, the same input jack as Component1 is used. The yellow connector is used for
Composite1 and the red connector is used for Composite2.

5.8 Tuning for Latency
For latency, the key parameters to work with are Video Delay and Number of B-frames.
Video Delay defines the number of milliseconds of buffering the encoder has to work with. The higher
this value, the more buffers 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 100.
B-frames improve the quality of the picture, but they also increase the latency by 1 frame time. To
minimize latency, the number of B-frames should be set to 0.
Figure 17 shows the suggested values for Video Delay and Number of B-frames for 3 common use cases:
Video Delay
# of B-frames
Case 1: Highest Quality, Highest Latency
9999
3
Case 2: Good Quality, Standard Latency
2000
1
Case 3: Normal Quality, Lowest Latency
100
0
Figure 17 Tuning for Various Use Cases
RTP offers lower latency than UDP, so for the lowest latency you should use RTP.
If you are streaming to VLC, you can reduce latency on the decode side by adjusting the network caching
value. By default, this is set to 1000ms. You can lower this to as low as 200ms. To do this, go to the
following:
VLC →Tools →Preferences →Show Settings (ALL) →Input / Codecs →Network caching (ms)

PERFORMING OTHER OPERATIONS WITH THE Z3-MVPR-02
6.1 Saving Current Settings
If you have a specific configuration of CH1 (and/or CH2) you’d like to preserve, you can save it so that
when the Z3-MVPR-02 is powered off and back on, it automatically uses those settings. This can be done
with the following steps:
(1) Once you make a change you want to save, click on “Save” at the bottom of the CH1 or CH2
configuration menu:
Figure 18 The “Save Settings”Button
If you reboot the Z3-MVPR-02, you should see that encode will automatically start with those
settings.
Click “Save” to
