The Next Generation of  
4K Digital Cinema 
						

							In 2007, Sony introduced an ultra-high-resolution projection system that incorporates 
an SRX-R220 4K SXRD projector and an LMT-200 Media Block, and adopts a unique self-
contained enclosure design.  Since its sensational debut, this projection system has rapidly 
acquired a huge reputation from a range of exhibitors worldwide due to its advanced 
features and functionalities specifically designed for digital cinema applications.
To respond to the evolving demands of digital cinema exhibitors, Sony is proud to 
introduce another unique digital cinema projection system.  
At the heart of this system are the SRX-R320P 4K SXRD projector and LMT-300 Media Block.  
Its secure enclosure design allows the LMT-300 server to be seamlessly integrated into the 
chassis of the SRX-R320P projector, providing a high level of security that meets the anti-
tamper regulation stipulated by the Digital Cinema Initiatives, LLC (DCI).
The SRX-R320P projector is equipped with three Silicon X-tal Reflective Display (SXRD™) 
devices, delivering an amazing resolution of 4096 x 2160 pixels (H x V) – more than four 
times the resolution of full HDTV (1920 x 1080), achieving a high contrast ratio of 2000:1.  
Thanks to selectable 4.2 kW, 3.0 kW, and 2.0 kW Xenon projector lamps and various 
optional lenses, the SRX-R320P allows for screen coverage of up to 22 meters (70 feet)* – 
providing a SMPTE-standard brightness level of 14 ft-L* on a wide screen.
The LMT-300 Media Block is a digital cinema server that incorporates hard disk drives 
(HDDs) with a large storage capacity of approximately 1.7 TB and adopts a reliable RAID 
(Redundant Array of Inexpensive Disks) system.  It can play back DCI DCP (Digital Cinema 
Package) files and allows the SRX-R320P projector to show digital cinema programs.  
Another unique feature of the LMT-300 is its Screen Management System function, which 
is equipped as standard and can provide a variety of screen-management operations 
such as show scheduling, communication with other theater control systems like lighting 
and curtains, and setup and maintenance of the projector.
Moreover, this projection system offers the optional STM-100 Theater Management System 
software that allows theater staff to efficiently manage multiple auditoriums from a central 
PC connected to the theater LAN. 
With extremely high resolution, 
outstanding security, and 
operational versatility, Sony’s digital 
cinema projection system based 
on the SRX-R320P 4K projector is a 
perfect choice for digital cinema 
applications.

System Advantages/Features
4K Resolution
Historically, the movie theater experience has always 
exceeded that achieved by home entertainment systems.  
The advent of HDTV (1920 horizontal pixels) and technical 
improvements in home theater equipment have stimulated 
the movie industry to think further ahead into the future.  
Meanwhile, the Hollywood movie studios have jointly 
agreed on standardizing 4K (4096 horizontal pixels) and 
2K (2048 horizontal pixels) as the next- generation digital 
movie distribution and projection standards.  Creating 
movies in 4K protects the future value of the content, and 
also provides a significant benefit to the theater audience.  
In recent years, stadium-type seating is becoming 
increasingly popular among modern cinema complexes.  
By sitting closer to the screen, the audience can enjoy 
a more immersive visual experience.  However, those 
sitting in the front rows may witness pixel artifacts when 
the resolution provided by the projection system is not 
sufficient to fill the screen size.  The SRX- R320P provides true 
4K output, which reproduces the full detail of 4K content 
thanks to the 4K SXRD panels, 4K internal signal processing, 
and 4K- compatible optical system.  Besides, since the  
SRX- R320P provides four times the resolution of 2K 
projectors, the visual quality of 2K and HD content is 
also improved over those provided by native 2K and 
HD -resolution projectors.

System Advantages/Features
High 2000:1 Contrast Ratio
The SRX- R320P offers a high contrast ratio of more than 
2000:1 through the use of Sony’s unique SXRD device.  The 
SXRD device itself achieves a contrast ratio of over 4000:1. 
This stunning picture quality makes the SRX- R320P ideal for 
applications in which dynamic range is essential.
The high contrast ratio has been achieved through two key 
technologies – the ‘normally black mode’ system and an 
extremely thin liquid crystal cell gap.
Xenon Lamp Provides Highly 
Bright and Pure Light Source
The SRX- R320P provides a high brightness of 14 ft- L* on a 
wide screen using a Xenon lamp at full brightness.  This 
high brightness can be achieved for a 65 -foot (20 -meter) 
wide screen when the SRX- R320P projects a full pixel size 
(4096 x 2160) image with a 4.2 kW Xenon lamp (USHIO  
DXL- 40SRXPRO only) and the brightness level is measured 
at the screen center with 100 IRE white and a screen gain 
of 1.8.  This brightness can also be achieved for a 55 -foot 
(17-meter) or 45 -foot (14-meter) wide screen when the   
SRX- R320P projects a full pixel size (4096 x 2160) image 
with a 3.0 kW or 2.0 kW Xenon lamp, respectively, and the 
brightness level is measured at the screen center with 100 
IRE white and a screen gain of 1.2.  
A Xenon lamp, standard in film projectors, provides pure, 
superb color tonal reproduction essential to meeting the 
stringent requirements of digital cinema.  Xenon lamps, 
which are designed for the SRX- R320P and available from 
lamp manufacturers, satisfy the wide color range required 
for digital cinema by dispersion at a very flat and wide light 
spectrum.
 *  A f t- L (foot- lamber t) is a unit of measurement for luminance.    
One foot- lamber t equals 3.4262591 candelas per square meter.
**  By lowering the brightness level of the projector lamp and at taching an 
appropriate ND filter to the projector lens, the SRX- R320P can be used for 
projection even on small screens.  With this brightness adjustment,   
the SRX- R320P with a 2.0 kW lamp can be used for a 15 -foot (4.5 - meter)   
wide screen.
Variety of High-quality Lenses
Five optional zoom lenses are available for the SRX-R320P.  
All lenses utilize very large image circles that contribute 
to minimizing the optical vignetting that typically occurs 
on projector lenses, and to obtaining the highest possible 
values of MTF (Modulation Transfer Function).  With these 
features, the optical systems of the SRX-R320P have the 
capacity to reproduce resolutions higher than 4K, which is 
necessary to project 4K content exactly at 4K resolution.  In 
addition, these lenses are designed to minimize chromatic 
aberrations using Sony’s accumulated technical knowledge.
Variety of Interfaces
The SRX-R320P supports a wide variety of signal formats 
including the 12-bit X’Y’Z’ signal that is stipulated in the DCI 
specification.  10-bit 4:4:4 RGB and 10-bit 4:2:2 YPbPr signal 
formats are also supported for playback of other alternative 
content.
n  Two channels of SRLV, which are used for connection to 
the LMT-300 Media Block (for 4K projection: 4K DCP).
n  A DVI (HDCP) interface that accepts DVI (HDCP) signals for 
up to 2048 x 1080 at 60 Hz (for 2K projection).
n  A dual-link HD-SDI/DC-SDI input* that accepts any of the 
following signals: 
•	For	 HD	projection: 	SMPTE	 372M	dual-link	 HD-SDI	(4:4:4),	or

Operational Features
3D Projection Lens Unit
Attaching the 3D projection lens unit* to its lens mount,  
the SRX- R320P can deliver crisp 3D images** to screens up   
to 50 feet (15 meters)*** in width at 4.5 ft- L brightness.  
It allows full 2K resolution for the left and right eyes 
simultaneously, resulting in a high-brightness, high- quality 
stereoscopic cinema presentation that offers more faithful 
reproduction of motion in 3D.
   *  For detailed information on the 3D projection lens units, please contact 
your nearest Sony of fice.
 **  To produce 3D images on a screen, 3D filters available from a 3D system 
integrator are required.  For detailed information on the 3D filters, please 
contact your nearest Sony of fice.
***  Screens up to 50 feet (15 meters) wide are suppor ted, when 3D images are 
presented in Side Masking mode.  When they are presented in Top - bot tom 
Masking mode, screens up to 40 feet (12 meters) wide are suppor ted.  
For detailed information on suppor ted screen sizes, please contact your 
nearest Sony of fice.
Anamorphic Lens
When projecting digital cinema content created in the 
CinemaScope format (4096 x 1716 pixels), the SRX-R320P 
cannot use all of the 4096 x 2160 pixels available for the 
4K SXRD device.  To improve this inefficiency, the optional 
LKRL-A001 Anamorphic Lens with Lens Changer Unit * was 
developed.  When CinemaScope images (4096 x 1716 pixels) 
are input, the SRX-R320P extends them in a longitudinal 
direction via the projector’s image-processing function, 
which effectively uses all the pixels of the SXRD device.  The 
LKRL-A001 attached** in front of the projector’s lens extends  the images in a transverse direction, so that the aspect ratio 
of the images projected on a screen can be restored to its 
original 2.39:1.  This can increase the brightness level of the 
images on the screen by approximately 20%, allowing for the 
projector to provide a high brightness of 14 ft-L on screens up 
to 70 feet (22 meters) wide***.
The LKRL-A001 includes a lens- changer function that can 
set the anamorphic lens not to be in use manually.  This 
function allows for the SRX- R320P to accept digital cinema 
content created in the Flat format (3996 x 2160 pixels), 
without dismounting the LKRL-A001 unit from the projector.
   * 
The LKRL-A001 supports the LKRL-Z214, LKRL-Z219, LKRL-Z117, and LKRL-Z119 
optional lenses. (The LKRL-Z211 is not supported.)
 **  To attach the LKRL-A001 to the projector, lens support stays are required.    
For detailed information, please contact your nearest Sony office. 
***  The brightness level may vary depending on portglass and screen conditions.

Anamorphic Mode Function
The SRX- R320P allows squeezed images (16:9 or 1.896:1) to 
be changed to 2.39:1 un-squeezed images.  This can be 
done electrically without an anamorphic lens.
Color Space Conversion (CSC) 
Function
The SRX- R320P features a Color Space Conversion (CSC) 
function, which helps users easily adjust the projector’s 
color space to that which is defined in the DCDM (Minimum 
D - Cinema Color Gamut) or ITU - R BT.709.  The target color 
gamut parameters required to meet the DCDM or ITU - R 
BT.709 standards can also be applied to the projector 
with this function.  The internal test generator simplifies 
adjustment and lets the operator align the projector in 
minutes.
Gamma Curve Selection
The SRX- R320P provides three preset gamma curve values.  
Users can select an optimum value from 1.8, 2.2, and 2.6 
according to the desired color tone.
Lens Shift Function
The SRX- R320P is equipped with a lens shift function that 
allows projected images to be moved up and down or 
from side to side.  This lens shift function can be operated 
manually via the finger screws incorporated on the 
projector’s unit.   Using this function, the position of the 
projected images can be moved vertically by - 50% to +50% 
and horizontally by - 5% to +5%.
Keystone Masking
To compensate for keystone distortion, which typically 
occurs when the projector is not installed directly in front of 
the screen, the SRX- R320P has an image -masking function.  
To determine the best position for the masking, this function 
allows users to set further two points in addition to the four 
corner points, which is particularly useful when projecting 
onto a curved screen.
Zoom/Focus Memory Function
The SRX- R320P is equipped with zoom and focus memory 
functions that make it easy to switch the projection 
between two types of aspect ratios.
When used with an optional zoom lens – such as the 
LKRL-Z211, LKRL-Z214, LKRL-Z219, LKRL-Z119, or LKRL-Z122 – the 
zoom and focus positions for the 1.85:1 screen format 
and 2.39:1 CinemaScope can be stored in the projector’s 
memory and then instantly recalled from there.  This allows 
for full-screen display regardless of the aspect ratio.  An 
electronic vertical alignment feature is included in the 
same memory to compensate for vertical changes in the 
image, should the projector be mounted at a downwards 
angle.

							Easy Maintenance of Luminance 
Level
During long periods of usage, users commonly have to 
adjust the luminance level of their projector, as Xenon 
lamps typically get darker over time.  The SRX- R320P has a 
convenient function to help users know when to make such 
adjustments.  It allows users to set a standard luminance 
level, and displays an alert message on the LCD screen of 
the projector when the value changes from the standard 
level.  With this feature, proper and timely maintenance of 
the luminance level can be performed.
Automatic Lamp Power 
Calibration Function
When switching the aspect ratio of projection from 
CinemaScope to VistaVision and vice versa, the luminance 
levels happen to change.  To maintain a constant 
luminance level even after making these changes, the  
SRX- R320P can automatically calibrate the luminance level 
by controlling the lamp output power.
Air-flow Sensor for Reliable Cooling
The SRX- R320P has a chimney on top of the unit that expels 
warm air, thereby keeping the projector unit cool.  The 
chimney has an air-flow sensor that measures the amount 
of discharged air.  When the projector is powered on from 
Standby mode, the air-flow sensor operates automatically.  
If the value does not reach a normal level, an alert 
message is displayed on the projector’s LCD screen.  
Thanks to this function, the operator can immediately 
take proactive maintenance action, allowing for reliable 
projector cooling.
Power Supply and Control of 
External Ventilation Fan
To efficiently discharge warm air from the unit, the chimney 
of the SRX- R320P projector must be connected to an 
exhaust duct with a ventilation fan.  For optimum reliability 
and effectiveness, the projector supports an Interlock 
interface, which enables the SRX- R320P to operate this 
external ventilation fan.  The projector can supply power to 
the fan and control its operation – the fan works when the 
projector is in Lamp ON mode or Standby ON mode.
Key Lock System
The SRX- R320P is designed to be highly secure.  It does 
not have screw holes, and requires physical keys to open 
the enclosure.  This body structure meets the anti-tamper 
requirement of the DCI.  Even if the enclosure is opened 
with the physical keys, anti-tamper sensors will trigger the 
LMT-300 Media Block to immediately start recording logs for 
further safety.  In this case, the projector also deletes Key 
Delivery Messages (KDM) automatically, so that DCP files 
cannot be played back.
SRX Controller Software
The SRX Controller software* is a convenient tool for system 
integrators to set up and maintain the SRX- R320P.  This runs 
on a PC** connected to the projector via the RS -232C 
interface, and features intuitive GUIs that enable easy 
setup and adjustment of the projector.  A comprehensive 
range of setup parameters including input configurations, 
colorimetry controls, installation adjustments, and 
maintenance settings can be controlled via this software.
For example, it allows operators to easily verify a lamp’s 
operating time.  Plus, the versatile projector functions 
such as Squeeze Mode, Color Space Conversion (CSC), 
and Zoom/Focus Memory can also be controlled via this 
software.

Maintenance and Security Features

In addition to its extreme resolution and high contrast,  
the SXRD device used in the SRX- R320P projector   
has the following remarkable   
technological features:
‘Normally Black Mode’ System
In every type of projection system, displaying absolute 
black is a major issue – as this helps to achieve a high 
contrast ratio.  In other words, the contrast ratio of a 
projector depends on how effectively the light from the 
source can be blocked, so it does not leak through the 
display device.
All Liquid Crystal Display (LCD) devices control the amount 
of light to be projected by applying an electric field to 
the liquid crystal gap.  In typical LCD devices, black is 
produced when an electric field is applied across the liquid 
crystal cell gap.  However, molecules near the surface of 
the glass substrate may not be accurately controlled due 
to the influence of the alignment film.  This is not an issue 
for bright images but, when displaying dark images, light 
may tend to leak from the LCD device, since the molecules 
near the surface are less accurately controlled.  This results 
in a creamy black instead of a deep black.  
The SXRD device does not exhibit these characteristics.  
This is because the ‘normally black mode’ system displays 
black when the electric field is not applied and, because 
all molecules are in the correct alignment, the polarized 
light alignment is also optimized.  The direct result is a far 
deeper black level, leading to a high contrast ratio.
Thin Liquid Crystal Cell Gap
Another important factor allowing for the high contrast 
of the SRX- R320P is the SXRD device’s ultra-thin cell gap 
of less than 2 micrometers.  With conventional ‘vertically 
aligned liquid crystal’ systems, a thin cell gap could not be 
achieved.  Sony has overcome this difficulty through the 
use of innovative planarization technology in the silicon 
backplane structure and an advanced silicon wafer-based 
assembly process. 
The SXRD device also adopts a structure that does not 
use ’spacers’.  These are columns found in conventional 
reflective liquid crystal devices to maintain a constant gap 
between the liquid cell floor and the top of the device.  
Spacers tend to both scatter and reflect light, which can 
impair high- contrast pictures.  In the spacer-less SXRD 
device, these artifacts are no longer seen.
Short Response Time
The thin cell gap structure in SXRD devices also contributes 
to an ultra-fast response time of 2.5 milliseconds (for both 
rise and fall).  The SXRD device reacts promptly to an 
instantaneous change of picture content, enabling SXRD -
based projectors to display smooth motion.  Consequently, 
the SRX- R320P virtually eliminates motion blur; a particularly 
significant benefit when presenting content that includes 
fast-moving objects.
Reliable Display Device
The SRX- R320P uses bright and highly powerful lamps.  As 
a result, special attention has been paid to the reliability 
of the SXRD device.  The inorganic materials utilized for 
the alignment layer of the SXRD device are resistant to 
deterioration or deformities that could occur due to the 
intense heat and light generated by the powerful lamp 
system.
12-bit SXRD Driver
The SRX- R320P utilizes a 12-bit display panel driver for 
reproducing extremely natural images.

Large Storage Capacity and 
Reliable RAID System
The LMT-300 incorporates HDDs with a large storage 
capacity of approximately 1.7 TB.  It employs a RAID 
(Redundant Array of Inexpensive Disks) system that allows 
for highly reliable digital cinema presentation.
Decryption and Unwrapping of 
DCP Files
The LMT-300 can decrypt DCP files that have been encrypted 
using the AES (Advanced Encryption Standard FIPS 197).  It 
can also unwrap individual picture, audio, and subtitle data 
files for processing that are encoded within the MXF file.
Picture and Subtitle
The LMT-300 can decode JPEG 2000 picture data in real time 
for playback, regardless of whether the file was encoded at 
2K or 4K resolution.  Subtitles in Timed-Text/XML or PNG/XML 
format can be overlaid onto picture data before it is sent to 
the projector.
Audio
The LMT-300 transcodes audio DCP files into AES/EBU digital 
audio signals, and then outputs them from two audio output 
connectors (D-sub 25-pin) to external audio processors such 
as Dolby
® sound processors.  The audio output 1 and audio 
output 2 can support up to 8 and 16 channels, respectively.  
The timing of the audio output can be adjusted for 
complete synchronization with the picture, and any channel 
can be routed to any output to simplify installation.
Log Creation
The LMT-300 can generate logs to record certain 
information – such as the number of times a movie has 
been played – which is a DCI requirement for secure 
content control.
Ingest of DCP Files During Playback
DCP files can be ingested to the LMT-300, even while 
playing a movie.
The LMT-300 Media Block is a digital cinema server with a large storage capacity and high reliability.  It can 
be seamlessly integrated into the chassis of the SRX-R320P projector, allowing for a highly secure digital 
cinema projection system.  The LMT-300 can handle DCI DCP (Digital Cinema Package) files that consist 
of picture, audio, and subtitle data files, and that are wrapped into an MXF (Material eXchange Format) 
file.  It can play back the DCP file by using advanced processing 
to decrypt and decode the picture data, and then send it to the 
projector over a secure multi-pin connection system.  
Moreover, the LMT-300 incorporates the Screen Management System 
(SMS) function, which lets operators manage all of the devices 
necessary for digital cinema presentation from one location.
