4K Digital Cinema Projector
The projector system consists of the SRX-R220 Digital Cinema Projector, the LMT-100 Media Block, and the LSM-100 Screen Management System, which are used with peripheral equipment such as RAID (Redundant Arrays of Inexpensive Disks) storage, an SMS Server, and an Uninterruptible Power Supply system.
The core component of this system, the Sony SRX-R220 projectors, are equipped with three Silicon X-tal Reflective Display (SXRD™) imaging 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).
The SXRD devices also provide a SMPTE-standard brightness level: 14 ft-L* on a 20-meter (65.6-foot) wide screen for the projector, along with a high contrast ratio of 2000:1. One of the major characteristics of these projectors is their enclosure design, which encases all of the system components required for exhibition including server, storage, SMS, security and power management.
This self-contained design realizes a high security level that meets the FIPS 140-2 SPB-2 anti-tamper regulation stipulated by the Digital Cinema Initiatives, LLC (DCI). It also simplifies installation since everything other than audio and automation is already wired and tested at the factory. Various lenses are available for the SRX-R220 projector, which provide zoom ratios as
short as 1.38x to as long as 7.0x.
The other important components included in this system are the LMT-100 Media Block and LSM-100 Screen Management System which, in combination with the SRX projectors, establishes a highly integrated digital cinema projection system. The LMT-100 Media Block is a digital cinema server that can play back DCI DCP (Digital Cinema Packages) files. The Screen Management System provides a variety of screen management operations such as show scheduling, content ingest, operator roles, and control of standard theater automation systems.
Moreover, this software also has various functions to help prevent illegal copying, such as the monitoring of cavity on the enclosure, security key management, and logging of any of security events.
With extremely high resolution, high-quality color tonal reproduction resembling film, and simple integration, the Sony digital cinema projector system based on the SRX-R220 4K projector is an ideal solution for digital cinema applications.
Historically, the movie theatre experience has always exceeded what could be achieved by home entertainment systems. The advent of HDTV (1920 horizontal pixels) and technical improvements in home theatre 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 provides a significant attraction to the theatre 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 an immersive visual experience. However, those sitting in the front rows may witness image artifacts if the projection system is at a lower resolution. The SRX-R220 provide the full detail of 4K content thanks to Sony’s SXRD imager, exclusive 4K internal signal processing, and newly designed 4K-compatible optical system. In addition, since the projectors provide four times the resolution of 2K projectors, the visual quality of 2K and HD content is
also maximized.
Offer a high contrast ratio of more than 2000:1* through the use of Sony’s unique SXRD device and proprietary optics. The SXRD imaging device itself achieves a contrast ratio of over 4000:1.
This stunning picture quality is ideal for cinema exhibition. The high contrast ratio has been achieved through three key technologies - the ‘Vertically Aligned Liquid Crystal’ system, an extremely thin liquid crystal cell gap, and a new optical path design.
* The contrast ratio is measured from a screen offering a gain of 1.0.
A Xenon lamp, standard in all film projectors, provides pure, accurate color tonal reproduction essential to meeting the stringent requirements of digital cinema. The SRX-R220 utilizes a 4.2 kW Xenon lamp, Lamps are available from Sony or many other lamp manufacturers.
Five optional zoom lenses are available for the SRX-R220. All lenses utilize very large glass optical components that contribute to minimizing the optical vignetting (darkening in the corners of the image) that typically occur on smaller projector lenses, while maintaining the highest possible values of MTF (Modulation Transfer Function). With these features, the optical systems of the projector have the capacity to reproduce resolutions higher than 4K, which is necessary to project 4K content exactly as the artist envisioned. In addition, these lenses are designed to minimize chromatic aberrations using Sony’s advanced optical technology.
The replacement projector lamp for the Sony SRX-R220 is: LKRX-2042A
