 and the brightness of the image. While much of the specification codifies work that had already been ongoing in the Society of Motion Picture and Television Engineers (SMPTE), the specification is important in establishing a content owner framework for the distribution and security of first-release motion picture content.

Digital cinema conforming to the DCI Standard is referred to within the film industry as D-Cinema while all other forms of digital cinema are referred to as E-Cinema. Thus, while D-Cinema is a defined standard, though one that is still partly being framed by SMPTE as of 2007, E-Cinema may be anything, ranging from a DVD

 player connected to a consumer projector to something that approaches the quality of D-Cinema without conforming to some of the standards. Even D-Cinema itself had evolved over time before the DCI standards were framed. However, the current DCI standards were made with the intention of standing the test of time, much like 35 mm film

 which has evolved but still retained compatibility over a substantial part of a century.

In addition to DCI's work, the National Association of Theatre Owners (NATO) released its Digital Cinema System Requirements.
The document addresses the requirements of digital cinema systems from the operational needs of the exhibitor, focusing on areas not addressed by DCI, including access for the visually impaired and hearing impaired, workflow inside the cinema, and equipment interoperability. In particular, NATO's document details requirements for the Theatre Management System (TMS), the governing software for digital cinema systems within a theatre complex, and provides direction for the development of security key management systems. As with DCI's document, NATO's document is also important to the SMPTE standards effort.

. Christie, long established in traditional film projector technology, is the maker of the CP2000 line of projectors—the most widely deployed platform globally (approximately 5,500 units in total). Barco designs and develops visualization products for a variety of selected professional markets including digital cinema. Their DP2K-32B digital cinema projector holds a Guinness World Record for the brightest projector with a brightness of 43,000 center lumens. Next to the DP series of 2K digital cinema projectors, Barco has a range of 4K digital cinema projectors, including the DP4K-32B (for screens up to 32 meters), the first - and still only - DCI-compliant enhanced 4K DLP cinema® projector on the market. NEC currently manufactures the Series II NC1200C, NC2000C and NC3200S 2K projectors for large, medium and small screen respectively, and the NC3240 in 2011 to represent the first generation 4k NEC DCI projector.

While NEC is a relative newcomer to Digital Cinema, Christie is the main player in the U.S. and Barco takes the lead in Europe and Asia. In addition Digital Projection Incorporated (DPI) designed and sold a few DLP Cinema units when TI's 2K technology first debuted but then abandoned the D-Cinema market while continuing to offer DLP-based projectors for non-cinema purposes. Although based on the same 2K TI "light engine" as those of the major players they are so rare as to be virtually unknown in the industry.

2010

As of June, 2010, there are close to 16,000 digital cinema screens, with over 5000 of them being stereoscopic setups.
Considering an article written by David Hancock (http://www.isuppli.com/media-research/marketwatch/pages/digital-screen-numbers-and-forecasts-to-2015-are-finalised.aspx), the total number of d-screens worldwide came in at 36,242, up from 16,339 at end 2009 or a growth rate of 121.8 percent during the year. There were 10,083 d-screens in Europe as a whole (28.2 percent of global figure), 16,522 in North America (46.2 percent of global figure) and 7,703 in Asia (21.6 percent of global figure). As regards digital 3D screens, there were a total of 21,936 3D screens, which equals 60.5 percent of all d-screens. This is a rise from the 55 percent in 2009 but is expected to drop slightly in 2011 to 57.5 percent.

Impact on distribution

Digital distribution of movies has the potential to save money for film distributors. To print an 80-minute feature film can cost US$1,500 to $2,500, so making thousands of prints for a wide-release movie can cost millions of dollars. In contrast, at the maximum 250 megabit-per-second data rate (as defined by DCI

 for new competition. This is caused by high costs and a lack of access to well-established production and distribution networks. By replacing film prints with hard disks the barrier to entry is significantly reduced, opening the market to competition.

The digital cinema rollout was stalled (as can be seen by major equipment purchases and future commitments to new equipment during this time); exhibitors acknowledged that they would not purchase equipment to replace projectors since the savings would be seen not by themselves but by distribution companies. The Virtual Print Fee model was created to address this (some claim by Frank Stirling at Boeing - Boeing was involved in digital cinema deployment at that time) and this was successfully done, accelerating the rollout of this technology and with it the reduction of the barrier to entry. Given that digital projectors make low volume distribution at last an economic possibility it is the studios' support of the VPF model that has accelerated the introduction of competition, both in terms of alternative distributors and also alternative content including cinematic series.

Alternative content

An added incentive for exhibitors is the ability to show alternative content such as live special events, sports, pre-show advertising and other digital or video content. Some low-budget films that would normally not have a theatrical release because of distribution costs might be shown in smaller engagements than the typical large release studio pictures. The cost of duplicating a digital "print" is very low, so adding more theaters to a release has a small additional cost to the distributor. Movies that start with a small release could scale to a much larger release quickly if they were sufficiently successful, opening up the possibility that smaller movies could achieve box office

 success previously out of their reach.
Alternate content is also finding a market in 3rd world countries in which the higher costs and quality of DCI equipment are not yet affordable.

Greater protection for content

A last incentive for copyright holders for digital distribution is the possibility of greater protection against piracy

. With traditional film prints, distributors typically stagger the film's release in various markets, shipping the film prints around the globe. In the subsequent markets, pirated copies of a film (that is, a cam) may be available before the movie is released in that market.

amongst others. With digital distribution, a simultaneous worldwide release would not cost significantly more than a staggered release.

Costs

On the downside, the initial costs for converting theaters to digital are high: $150,000 per screen on average. Theaters have been reluctant to switch without a cost-sharing arrangement with film distributor
Film distributor
A film distributor is a company or individual responsible for releasing films to the public either theatrically or for home viewing...

s. A solution is a temporary Virtual Print Fee system, where the distributor (who saves the money of producing and transporting a physical copy) pays a fee per copy to help finance the digital systems of the theaters.

While a theater can purchase a film projector for US$50,000 and expect an average life of 30–40 years, a digital cinema playback system including server/media block/and projector can cost 3–4 times as much, and is at higher risk for component failures and technological obsolescence. Experience with computer-based media systems show that average economic lifetimes are only on the order of 5 years with some units lasting until about 10 years before they are replaced.

Archiving digital material is also turning out to be both tricky and costly. In a 2007 study, the Academy of Motion Picture Arts and Sciences

 found the cost of storing 4K digital masters to be "enormously higher - 1100% higher - than the cost of storing film masters." Furthermore, digital archiving faces challenges due to the insufficient temporal qualities of today's digital storage: no current media, be it optical disc

There were many prototype systems developed that claim a first in some form of digital presentation. However, few of these had a significant impact on the advance of the industry. Key highlights in the development of digital cinema would likely include: demonstrations by TI

Standards development

The Society of Motion Picture and Television Engineers began work on standards for digital cinema in 2000. It was clear by that point in time that HDTV did not provide a sufficient technological basis for the foundation of digital cinema playback. (In Europe and Japan however, there is still a significant presence of HDTV for theatrical presentations. Agreements within the ISO standards body have led to these systems being referred to as Electronic Cinema Systems (E-Cinema).)

Claims to significant events

The development of Digital Cinema was a broad-based industry project involving many companies and development teams. Many instances of video or digital playback occurred during the early 2000's and claims to significance for the development of the industry vary.

[There is insufficient context and verified history to determine the influence and impact of many of these early demonstrations. However, presented herein are claims for significant developments]

 with the TI mark V prototype projector.

Technicolor manufactured the DVDs for uploading on these test systems and was responsible for sending technicians out to the locations for every new feature film that was played. The technicians would typically spend ten or so hours to load the files from the DVD to the QuBit, set up the server to play the files, and then set up the projector. A full rehearsal screening of the feature was mandatory as was the requirement to have back up DVDs and backup QuBits available should something fail.

The systems were eventually replaced or upgraded after TI made improvements to the projectors and Technicolor developed a purpose-built digital cinema server in a venture with Qualcomm

. The new systems were called AMS for Auditorium Management Systems and were the first digital cinema servers designed to be user friendly and operate reliably in a computer-hostile environment such as a projection booth. Most importantly, they provided a complete solution for content security.

The AMS used removable hard disk drives as the transport mechanism for the files. This eliminated the time required to upload the DVD ROMs to the local hard drives and provided the ability to switch programs quickly. For security, the AMS used a media block type system that placed a sealed electronics package within the projector housing. The server output only Triple DES
