1 Introduction

The Dolby Vision Content Mapping Unit (CMU) 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 CMU 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 CMU 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 CMU 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 CMU in an operating environment.

2 Setup

Initial connectivity

The CMU 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 CMU 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 CMU to

the color grading or mastering system.

3. For connecting a display to the CMU, 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 CMU.

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 CMU using the following user name
and password:

User name: admin

Password: Dolby1234!

DHCP network configuration

For a DHCP network, make sure that the CMU 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 CMU’s MAC address:

/sbin/ifconfig

There may be multiple network devices on the CMU. Depending on the physical setup, the MAC address
you want should be attached to network device enp5s0f0 or en0 depending on the CMU’s generation.
Provide this MAC address the networking administrator. Once the MAC address is entered to their

Dolby Vision CMU user manual Page 7

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 CMU for a static IP configuration.

Network verification

After configuring the network settings on the CMU, 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 CMU IP address you assigned for the CMU to display the CMU 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 CMU 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 CMU.
The CMU automatically configures the output SDI interface to match the input SDI interface. If needed,
the CMU can be set to force a 3G SDI output, even if the input SDI is dual-link HDSDI, see the CMU

Configuration page.

Additionally, the CMU with Kona 4 supports HDMI output to a Dolby Vision television.We
recommend that you use 3G connectivity, because of the reduced wiring necessary. Additionally, there
are fewer timing and VPID identification issues when using 3G connectivity. The CMU 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 CMU 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.
