1 Introduction
The Dolby Vision Content Mapping Unit (eCMU) is an external processing box provided by Dolby that
enables the following Dolby Vision functionality:
• Enables the GUI and controls for Dolby Vision in a Dolby Vision-enabled color grading or
mastering system
• Contains the master database for Dolby Vision Mastering Monitors and output Target displays
• Real-time Content Mapping (CM) processing
The eCMU performs the content mapping function from content with embedded Dolby Vision metadata
through a SDI interface for a selected target display. The applications enabled with Dolby Vision must
also communicate with the eCMU via a network; either connected directly or as part of a larger house
network. This traffic is minimal and generally only occurs at startup or project initialization time. The
following eCMU setup procedure shows how to setup and test the network and briefly describes SDI
connectivity.
Alternatively, you can send content with embedded Dolby Vision metadata through HDMI tunneling for
quality control.
Note:
• HDMI tunneling with a consumer TV should not be used for mastering.
• HDMI tunneling output only supports HD resolution. This signal will be upscaled in the TV.
The following diagram shows the most common configuration for the eCMU in an operating
environment.

2 Setup
Initial connectivity
The eCMU is a head-less box designed to reside in a rack in the server room with no GUI explicitly
running. This is only an issue when the network has not been configured to work for the environment in
which it is installed. Therefore, it is advisable to setup the machine with a VGA monitor and USB
keyboard before you begin operations.
Follow these steps to connect to the network.
1. Unbox the eCMU and connect power, making sure there is sufficient ventilation top and bottom.
2. For SDI connection, locate the included mini-SDI-to-SDI cable harness that connects the eCMU
to the color grading or mastering system.
3. For connecting a display to the eCMU, either use the included mini-SDI-to-SDI cable harness to
connect to a reference monitor or the included mini-HDMI cable to a Dolby Vision TV.
4. Connect a network cable to the first port (nearest the USB ports) and plug it into the switch or
other networking infrastructure in which the color grading or mastering system is also connected
to.
5. Plug a USB keyboard into a USB slot. You do not need a mouse, as there is no graphical user
interface.
6. Connect a monitor to the VGA port. Do not connect the monitor to the graphics card.
7. Plug in the power cable and turn on the machine; all the services will automatically start.
The following figures show the front and back of the Dolby Vision eCMU.

Network setup
Configure the default network for DHCP. If the installation site has a DHCP server, it automatically
negotiates an address. However, many networks either use static DHCP, or manually assigned addresses.
In these environments, it is necessary to assign a static IP address.
Once you have determined the type of network to use, log in to the eCMU using the following user name
and password:
User name: admin
Password: Dolby1234!
DHCP network configuration
For a DHCP network, make sure that the eCMU has connected and successfully obtained an IP address.
To obtain the IP address, run the following command once logged in:
/sbin/ifconfig
Example Output:
[admin@dlb-CMU-06 ~]$ ifconfig
enp5s0f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.204.189.27 netmask 255.255.192.0 broadcast 10.204.191.255

TX packets 126 bytes 20113 (19.6 KiB)

device memory 0xfb220000-fb240000
Note: It may take 30 to 60 seconds to bind to a DHCP server if the DHCP servers have churn processing
turned on.
Static DHCP network configuration
For a static DHCP network in which the network addresses are served based on the MAC address, log in
and run the following command to display the eCMU’s MAC address:
/sbin/ifconfig
There may be multiple network devices on the eCMU. Depending on the physical setup, the MAC
address you want should be attached to network device enp5s0f0 or en0 depending on the eCMU’s
generation. Provide this MAC address the networking administrator. Once the MAC address is entered to
Confidential Information
Dolby Vision eCMU user manual Page 8
their system, simply reboot, and make sure the network automatically picked up as occurs in a normal
DHCP network.
Static IP address configuration
The most complicated setup configuring for a static IP address. Contact your Linux administrator to setup
the eCMU for a static IP configuration.
Network verification
After configuring the network settings on the eCMU, access the built-in web application by opening a
web browser on Chrome, Firefox or Safari on a computer that is connected to the same network.
Navigate to the eCMU IP address you assigned for the eCMU to display the eCMU web page. For future
access, create a bookmark. It is useful to check the SDI status and other log pages during operation.
Single Card AJA Kona 4 setup for 2K/HD
The eCMU with a single AJA Kona 4 SDI card is compatible with a dual-link 1.5G HDSDI, single-link
3G Level A/B SDI or quad-link 3G Level A/B SDI, depending on the hardware configuration of the
eCMU. The eCMU automatically configures the output SDI interface to match the input SDI interface. If
needed, the eCMU can be set to force a 3G SDI output, even if the input SDI is dual-link HDSDI, see the
eCMU Configuration page.
Additionally, the eCMU with Kona 4 supports HDMI output to a Dolby Vision Television. It is
recommended that you use single-link 3G Level B connectivity to reduce wiring complexity. The eeCMU
is designed to process 12-bit RGB 4:4:4 content; therefore, the supported frame rates are only those in
which a 4:4:4 RGB signal can be displayed (23.976, 24, 25, 29.976, 30 are all possible). The eCMU
examines the input signal and adapts based on the VPID and connection state it detects on the wire. If the
application does not output a VPID, it assumes 24fps 4:4:4 RGB 12-bit.
