About XD20 Media Player
The XD20 Media Player is the latest audio/video playback system created by DTS Digital Cinema. It has
been engineered to deliver eight channels of digital surround sound (plus a narration channel). It is a fullfeatured media solution with pre-show programming and networking capabilities.
Options that are enabled via licensing include:
• Soundtrack Playback (including playing 5.1 audio to timecode)
• HD Video
• CSS Cinema Subtitling System (subtitling, captions, and audio description).
A second hard drive (RAID) may optionally be installed into the XD20 chassis.
The XD20 Media Player has a large-capacity internal hard drive, which can store approximately 30 full-
length feature soundtracks. XD20 connects directly or via network to an external DVD drive unit (see
Appendix M).
To get the most out of your XD20, we suggest that you review this manual and keep it available during
system installation and initial operation.
We publish the Tech Talk newsletter with tips and updates for Service Technicians. Tech Talk is
published quarterly, and mailed. If you would like to be added to our mailing list, contact DTS Digital
Cinema Technical Support. It is also posted on the free online Support Center located on our website at
www.dtsdcinema.com/Support/.

1.2. Powering ON the XD20 Media Player
Start by turning ON the front panel power button. It typically takes the system 90 seconds to initialize.
The XD20 boots from the Flash drive that is connected (internally) to its motherboard. It may take an
additional minute if the system is performing one of its periodic self diagnostics.
The Flash drive contains enough information to be able to check and repair the data on the hard drive.
The application software runs from the hard drive. Built-in diagnostics will check the hard drive and
software upon boot. A message appears on the display if a problem is found.
While the system is initializing, the following messages will appear on the LCD screen on the front panel
of the XD20 chassis.
Wait until the screen displays the Ready message before using it.
If no messages appear on the LCD screen after you have turned on the power switch, check the
following:
Is the power to the sound rack on? Has the sound rack breaker been tripped?
Is the power cable connected?
Are all internal cables connected and boards well seated?
1.3. LED Indicators
The table below describes the LED functions on the XD20 front panel. The AUDIO LED lights blue
when active. The other LEDs light green when active.

2. Loading and Playing Content
2.1. Types of Content
The XD20 Media Player plays these types of content:
• Soundtracks (Features and trailers)
• Preshow Video (Standard and High Definition)
• CSS (Cinema Subtitling System: Subtitling, Captioning and Audio Narration)
• ACV (Alternate Content video)
2.1.1. Soundtrack Content
Soundtracks are DTS audio files for features and trailers. They are normally delivered on discs, which are
inserted in the drives of the external DVD drive unit and saved on XD20s hard drive. If the XD20 is
networked, soundtracks may be loaded via network using proprietary DTS Digital Cinema software.
2.1.2. Preshow Video Content
DTS video content can be delivered in several ways: discs that can be downloaded to XD20 or content
delivered via a network, or via USB hard drive or USB portable “memory stick”. The video content
includes a configuration file that determines the video playlists, schedules and automatic start times.
The creation of content discs is not covered in this manual.
XD20 will not play standard consumer DVD movies or music CDs. XD20 content DVDs for
cinema must be created using proprietary DTS Digital Cinema software.
2.1.3. Alternate Content Video
Playback of Alternate Content Video (ACV) is an XD20 capability that comes with the HD Video option.
There is reserved disk space for ACV, which is separate from the space for Film and Preshow content.
Multiple playlists can be loaded into the XD20. Unwanted playlists must be manually deleted.
Appendix K describes the process of creating ACV playlists and loading them onto XD20 using the ACV
Playlist Generation software.
2.1.4. CSS Content
The DTS Access™ system was designed to aid hearing impaired and visually impaired audiences. In
addition, it is also capable of language translations.
In order to use the CSS system, your XD20 Media Player must have a license for the CSS Option. Three
types of program content may be provided to a theater equipped with an XD20 that has the CSS option
installed.
• Projected Subtitles or Captions
• Captions for rear data wall
• Narration
The CSS content is not delivered with the feature soundtrack disc(s). They are delivered separately. CSS
discs will be labeled “DTS Access™” and with the same show title and serial number as the feature
soundtrack disc. The disc label also shows what type of CSS content is included, as not all types of CSS
content are included with all CSS discs.
Not all features provide a DTS Access™ disc. Check with your distributor or contact DTS
Digital Cinema for features that are available.
The CSS playback works the same as DTS feature audio playback, in the sense that the film contains
timecode that must match the assigned film and audio serial numbers. This prevents playback of the
wrong content with the wrong feature.
Document # 9301H264001.0
6
XD20 Installation and Operating Guide Version 1.0
The projectionist threads the film through the D600 Timecode Reader Head on the projector, and when
the show starts, the CSS will play automatically, synchronizing the content to the film. Some operational
tasks can be performed by the projectionist. These are explained in more detail under Playback Menu, in
Chapter 3.
CSS Terminology
These are some of the terms associated with the CSS Option.
Table 7: Definitions of Terms
Term Definition
CSS Cinema Subtitling System. A system designed by DTS Digital Cinema that provides
DTS Access™ content.
DTS Access™ Group of delivery playback files that include subtitles, narration, and Rear Window™.
(Rear Window is a trademark of WGBH public broadcasting system in Boston.)
Subtitle Projected text of on-screen dialog. Often this has been translated into a language
different than the original version.
Caption “front captions” – Projected text on screen that contains both film dialog and sound
descriptions. This is also referred to as Open Caption.
Rear Window™ “rear captions” – This system consists of a LED reader board (display) mounted on the
rear wall of the theater. It receives serial data from the CSS and displays caption text
that is reflected on individual reflectors (rather than captions displayed on the screen).
Narration This is an audio description of on screen action during feature playback. It is normally
received via an IR (Infrared) or FM (Frequency Modulation) device to a head set worn
by an audience member.
CSP Cinema Subtitle Projector is a custom designed video projector for use only with the
CSS Option.
EMA External Masking Apparatus – A bracket that holds the CSP (cinema subtitling
projector). Also contains a special douser and masking system

XD20 Installation and Operating Guide Version 1.0
2.2. Content Delivery
Most content is delivered on discs. Customers who have XD20 with the HD Video Option may make
arrangements with DTS Digital Cinema to receive video and ACV content via a network.
2.2.1. Types of DTS Discs
DTS theaters receive most content on CD-ROM discs. There are several types of discs.
• DTS Soundtrack discs for feature films.
Soundtrack discs are issued by the film studios' distribution companies and must be returned with
the prints. Feature film soundtrack discs sometimes include trailers.
• DTS Trailer discs. These discs only contain trailer soundtracks. Trailer discs are distributed by
DTS and do not have to be returned.
• DTS Video discs. These discs contain XD20 video content, playlist and schedule information.
These discs do not have to be returned.
• DTS Access™ discs are issued by the film studios' distribution companies and must be returned
with the prints. Access discs may include any or all of the following and will only play when the
XD20 Media Player has the CSS option:
o CSS subtitles or front captions (projected on the screen)
o “Rear” Captions (captions displayed at the rear of the theater and onto a “Rear
Window
o Audio Description that describes action on screen (Narration).
XD20 will only accept a disc made specifically for DTS cinema playback equipment. XD20
will reject consumer CD audio or DVD type discs.
TM”
display)
2.3. Loading Content
Generally, any DTS feature soundtrack disc (film or trailer), DTS Access™ disc (with CSS content), or
DTS video content disc will automatically load when inserted in the external DVD drive unit. The content
will be copied onto the XD20 hard disc for playback at a later time. XD20 will store several soundtracks
and/or DTS Access™ discs for multiple features and trailers.
XD20 will only accept a disc made specifically for cinema playback. XD20 will reject consumer CD
audio or DVD type discs.
Please note that DTS soundtrack feature discs do not contain CSS files for the feature. CSS content for a
feature is on a DTS Access™ disc, and must be loaded separately. It does not matter whether the DTS
Access™ or soundtrack disc is loaded first. The CSS content for a feature can be loaded and played
without the DTS soundtrack for the same feature.
2.3.1. DTS Soundtrack Discs
Soundtrack discs can be single discs or come as sets of double or triple discs.
• 1-disc soundtrack. DTS soundtrack for films running about 90 minutes or less may be delivered
with one disc. These discs are labeled as "one disc only".
• 2-disc soundtrack. Films running 90 minutes but less than three hours will likely require two
discs which are labeled “Disc A” and “Disc B”. These movie soundtracks discs must be loaded as
a set.
• 3-disc soundtrack. In rare cases, a soundtrack may require three discs (“Disc A”, “Disc B” and
“Disc C”) if it runs more than 3 hours. Loading a three disc soundtrack must be done in two
separate load processes.
• DTS trailer soundtrack discs. Trailer discs are always single discs.
Document # 9301H264001.0

XD20 Installation and Operating Guide Version 1.0
2.3.2. Loading Soundtrack Discs
The XD20 must be licensed to enable it to load specific types of content:
• CSS content will not play from any XD20 not licensed for CSS.
• An audio disc will not load if not licensed for soundtrack.
• A video/ACV disc will not load if not video enabled.
Note: An exception to this occurs when network transfer is enabled. The XD20 will then load any film
(soundtrack or CSS) content so that it may be distributed to other units, but will not play back the content
if not licensed.
Refer to the Licenses Menu in section 3.3.2 to see which licenses are loaded.
1 Start while XD20 is not playing content. The status display should read “Ready.”
2 Open the DVD drive (in the external DVD drive unit) by pressing the Open/Close button adjacent
to the tray. Place the disc in the tray with the printed side up. For a two-disc or three-disc
soundtrack, place disc A into drive A and disc B in drive B.
3 Close the tray by pressing the Open/Close button, and the external DVD drive unit will check the
contents of the disc before loading. If it detects an error, it will display one of the following
messages on the XD20 LCD display.
This warning message indicates that one disc of a two-disc set was not inserted. To add the
second disc, first eject the one disc and start over with both discs. This warning may also occur
for a three-disc set and can be ignored. Press Enter to ignore the warning and proceed to load the
contents.
This error message indicates that the two-disc set inserted in the drives is not a matching set. This
could be caused by any of the following:
o The discs are from different movies.
o The discs are for the same movie but one is in a different language.
o The discs are duplicates
o One of the discs is not a cinema movie disc.
4 Eject the disc and start over with the matching discs. Pressing Enter will ignore the error, but the
soundtrack loaded might be incomplete.
Document # 9301H264001.0
9
XD20 Installation and Operating Guide Version 1.0
5 When the load process begins XD20 displays information about the content currently being
copied. For example:
Typical load time is three minutes per disc. The following message appears when the load is
complete.
6 Press Enter and the disc trays will open. Remove the disc(s) from the tray(s). Press the
“open/close” button to close the tray(s).
7 Repeat steps 1 through 6 for “Disc C” of a three-disc soundtrack.
8 Place the DTS soundtrack discs back in the film canisters for return to the depot.
2.3.2.1. Compatibility with Legacy Soundtrack Discs
Old DTS soundtrack discs did not contain a language ID. If you load an older disc that does NOT contain
a Language ID, and if Language Versions is enabled, XD20 will prompt you to identify the playback
language desired. If you are prompted, you must identify the playback language of the disc. If Language
Versions is disabled, XD20 will NOT prompt you to identify the language.
If you load a disc and are prompted for the language, you must select the language from the Languages
menu. The only selection you make should match the language listed on the disc label.
See Table 15 on page 89 for a list of available soundtrack languages.
After selecting a language, a confirmation screen will display.
Yes – Confirm the language is correct and load disc.
No – Go back to the language menu and make a new selection.
Abort – Stop the load process and eject the disc.

XD20 Installation and Operating Guide Version 1.0
2.3.3. Handling a CD-ROM Read Error
The following message may appear on the screen if an error occurs while XD20 is loading the soundtrack
disc:
The options are:
Press Enter to continue loading the incomplete material, or
If you press Enter, then a portion of the audio data will be missing. When the soundtrack is played, it will
revert to the fallback format when it reaches the missing data. It will return to the DTS format when it
sees valid data. If you load the disc again, it will only attempt to copy the missing data.
Pressing ◄ aborts the loading process. The drives will open and eject the discs. The data that was already
copied from the hard drive will be deleted. Replacement discs for soundtracks can be requested from the
film distributor. Replacement discs for trailers and special options can be requested from DTS.
Press ◄ to Abort without loading any of the soundtrack.
2.3.4. Loading DTS Video Content Discs
DTS video content discs will only load on an XD20 that is equipped with the HD Video Option. The
procedure for loading DTS Video Content discs is:
1. Start while XD20 is not playing content. The screen will display the following message.
2. Open the DVD drive (in the external drive unit). Place the disc in the tray with the printed side
up.
3. Close the tray. The XD20 will check the contents of the disc before loading to ensure that it does
not reload preexisting video content.
When the load process begins, the XD20 will display information about the content currently
being copied. For example:
The following message will appear when the load is complete.
4. Press Enter and the disc trays will open. Remove the disc from the tray.
2.3.5. Loading a DTS Access™ Disc
DTS Access™ discs are always single discs labeled with the name of the feature film and the language of
the content on the disc. To load a DTS Access™ disc, follow these steps:
Document # 9301H264001.0
11
XD20 Installation and Operating Guide Version 1.0
1. Start when “Ready” is displayed on the LCD screen on the XD20 front panel.
2. Open the drive (in the external drive unit), place the disc in the tray with the printed side up, and
close the tray. The XD20 will display information about the content being copied. For example:
The following message will appear when the load is complete.
3. Press Enter and the disc trays will open. Remove the disc from the tray and close
the tray.
DTS Access™ discs will load onto the XD20 even if the unit is not licensed for the discs.
However, they will only play back on XD20 units that have a CSS license.
2.3.6. Loading ACV
See Appendix K for information regarding creation of ACV playlists.
These menus apply whether the ACV is loaded from DVD or hard drive.
1. Start when “Ready” is displayed on the LCD screen on the XD20 front panel.
2. Open the drive (in the external drive unit), place the disc in the tray with the printed side up, and
close the tray. The XD20 will display information about the content being copied. The message
shown below displays while loading ACV content.
The following message appears if the Playlist already exists. Other playlists on the disc should be
loaded.
The following message appears if the content cannot be loaded due to space limitations. In the
example shown, the system ran out of disc space part-way through the playlist named
Document # 9301H264001.0
12
XD20 Installation and Operating Guide Version 1.0
“Nahuala2”. Any clips loaded from the playlist prior to reaching the limits of disc space will be
retained on the disc, but the playlist itself will not play. To load the new playlist in its entirety,
you must delete sufficient nonessential ACV content.
The following message appears if the all content and playlists were loaded without errors.
Document # 9301H264001.0

XD20 Installation and Operating Guide Version 1.0
2.3.7. Loading Content via USB
A USB memory stick or a USB external drive can be used to load content into the XD20. See Section
3.2.5 Load from USB.Loading Film Content Using a Local Network
For a complete description of setting up and using your XD20 for Network loading, please see Section
7.8.5 Network.
For a local networked system, automated distribution of film content can be enabled (the default is OFF).
• Soundtrack and CSS content may be automatically distributed to all XD20s connected in a
closed or local network. Content distribution is limited only to other XD20s on a local
network and cannot be copied outside of the theatre.
• DVDs for Preshow or Alternate Content video will only load on the local XD20 unit and
cannot be distributed through the network automatically.
When connecting XD20s in a stand-alone network, Language Versions must be set the same on all
networked units. If this is not done, the soundtrack content loaded on a unit with Language Versions
disabled will not play on a unit with Language Versions enabled.
When content is loaded into a DR-1 that is connected to a network of XD20s, the content will be
distributed to all the XD20 players. See Figure 2, below.

Due to the fact that the XD20 reserves 25GB of hard drive space for film content, a movie that plays for
an extended period of time may get deleted from the drives of any units that have not played that movie
for some time. For example, suppose that a busy multiplex loads 5 new titles per week into the DR1/XD20 network. After approximately 5 weeks of loading 5 movies per week, the 25GB of available
space on the hard drives will have been utilized. At this point, the least frequently shown movie on each

In the case shown in Figure 3 below, after 5 weeks, the popularity of Francisco's Folly has tapered off
such that the theater manager decides it should be shown on Screen “n” instead of Screen 2.
Unfortunately, since Francisco’s Folly has not been playing on Screen n for more than 5 weeks, it has
been deleted from Screen n’s hard drive to make room for other content. In order to get Francisco’s Folly
back onto the hard drive of Screen n, it must be loaded back into the DR-1. (This also holds true if the
content had been deleted manually rather than automatically.)

As an alternative to reloading the discs into the DR-1, it is possible to increase the space allocated on the
hard drive of any XD20 so that it will hold more film content. The necessary increase in space would
depend upon the rate of loading new titles and the number of weeks of play on a given screen. See - Film
Reserved, under the Disc Space section on page 107, for specifics on increasing allocated space for film
content.
2.4. Managing Disk Space
The XD20 250 gigabyte hard disk reserves 25 gigabytes of space by default for film soundtrack and CSS
content. (See Disc Space in section 7.9 for information on changing the amount of reserved space.) XD20
uses about one G-byte of space for an average two-hour feature with soundtrack including DTS Access™
content, such as subtitles. Alternatively, one G-byte can also hold content for approximately 50 threeminute trailers.
XD20 automatically ensures there is enough storage space on the hard drive before loading new feature
and trailer soundtracks. When necessary, it deletes old material to make room for new content. Old
material consists of the features and trailers that have not been played for the longest duration of time. All
content associated with the selected feature or trailer, such as different language versions, is deleted at the
same time.
