stipulated terms of guarantee. On receipt, the purchaser must immediately inspect all
delivered goods for damage incurred during transport, as well as for material and
manufacturing faults Barco must be informed immediately in writing of any complaints.
The period of guarantee begins on the date of transfer of risks, in the case of special

impossible or unsuccessful, the purchaser can demand a reduction in the purchase price or
cancellation of the contract. All other claims, in particular those relating to compensation for
direct or indirect damage, and also damage attributed to the operation of software as well
as to other services provided by Barco, being a component of the system or independent
service, will be deemed invalid provided the damage is not proven to be attributed to the
absence of properties guaranteed in writing or due to the intent or gross negligence or part
of Barco.
If the purchaser or a third party carries out modifications or repairs on goods delivered by
Barco, or if the goods are handled incorrectly, in particular if the systems are commissioned
operated incorrectly or if, after the transfer of risks, the goods are subject to influences not

As the ideal peripheral for all Barco digital cinema installations, ACS-2048 is an 8 x 1 video
switcher that accepts "universal" input formats, and outputs up to 12-bit DVI at 2048 x
1080. With a high-quality scaler at its core, upconverting any input format is as simple as
"auto-acquiring" and selecting the desired input. However, disguised as a switcher, ACS-
2048 is a pathway to new revenue streams for your facility. By enabling "alternate" content
to be displayed in the digital cinema resolution, your theatre's role as a presentation facility
for events, businesses, conventions and so much more — becomes a reality.
Please note:
•To ensure trouble-free installation and operation of your ACS-2048, please follow
all procedures in the following two sections:
~Chapter 3, “Installation” on page 25.
~Chapter 4, “Operation” on page 31.
•Should you have any questions regarding the installation or operation of the ACS-
2048=system, please consult with the factory. Refer to Appendix C, “Contact
Information” on page 107 for contact details.
cÉ~íìêÉë
Major features of the ACS-2048=system are listed below:
•Supports “universal” inputs: HD-SDI, SD-SDI, DVI, Analog, Composite, and S-
Video. All inputs support standard interlaced sources, and all input connectors
are located on the front panel for user convenience.
•Provides motion adaptive de-interlacing and advanced noise reduction circuits.
•Provides an HDCP "decrypted input" and "encrypted output" path. This feature
enables copy-protected content to be displayed at digital cinema resolutions,
while maintaining copyright security. Refer to the “A Word About HDCP” section
on page 15 for additional information.
•Provides twin-link 12-bit DVI outputs for upconverting all inputs to 2048 x 1080.
•Includes a user-friendly front panel and an intuitive menu display.
•Provides integration with the “Communicator” touch screen on Barco digital
cinema projectors, enabling seamless remote control.
•Includes input file management plus a standard “Auto Acquire” mode.
•The output adjustment feature enables the entire output to be scaled to fit the
actual theatre’s physical setup (e.g., curtains, drapes, and off-axis projection).

This section lists the new or modified features that have been implemented since the last
revision of the ACS-2048 User’s Guide. Reference links are provided for additional details.
•Input Files
The number of input files has been increased from one per input to a global pool
of 64 files. This feature enables users to store more than one file for a given input.
When managing files, users can select specific file numbers for the save, delete,
and recall functions. In Chapter 4, refer to the “Input Menu” section on page 43
for information about this feature.
•File Association Menu
A File Association menu has been added to the System Menu that enables
users to associate an input configuration file with each of the eight inputs. This
function tells the system which file to use when an input is selected from the front
panel. In Chapter 4, refer to the “File Association” section on page 64 for details.
•Remote Commands
New remote commands have been added to the ACS-2048’s command library,
and several commands have been modified:
~ICSAV: modified command

About the ACS-2048
^=tçêÇ=^Äçìí=ea`m
HDCP stands for High-Bandwidth Digital Content Protection,an industry-wide copy
protection scheme that is used to prevent the potential interception of digital data between
the source (e.g., a Blu-Ray player) and the target display (e.g., a digital cinema projector).
The HDCP format was designed by Intel, and it uses an “authentication and key exchange”
procedure to accomplish the required protection. For proper implementation, products that
are compatible with the HDCP format require a secure connection to a compliant display,
such as a digital cinema projector.
In digital cinema applications in which an ACS-2048 is used, when an HDCP compliant
device is connected to the ACS-2048, an HCDP “session” is created. In this session
(which is transparent to the user), “keys” are exchanged between the source device (e.g., a
Blu-Ray player) and the digital cinema projector. The source device queries the display to
ensure that the equipment is HDCP compliant before video is shown. Note that non-HDCP
equipment such as PCs will work with any DVI compliant display, but HDCP compliant
equipment only shows content on HDCP compliant displays.
Please note the following important points:
•When an HDCP compliant device is connected to the ACS-2048 and that specific
input is selected, the Status Menu indicates if HDCP is enabled.
•If the “session” determines that the target display device is non-HDCP compliant
(e.g., if the user is attempting to make an illegal copy on an external recorder), an
error message appears on the ACS-2048’s Status Menu, indicating that video
cannot be shown.
•HDCP compliant repeaters cannot be connected to the output of the ACS-2048,
as the ACS-2048 must be the last device in the HDCP "chain" — prior to the
HDCP compliant display device (projector). If an HCDP repeater is connected,
the message “HDCP Violation” appears on the Status Menu. Refer to the
“Status Menu” section on page 67 for additional details.
