Because feature films in digital form are encrypted and the decryption keys KDMs are locked to the serial number of the server used linking to both the projector serial number and server is planned in the futurea system will allow playback of a protected feature only with the required KDM.
In Augustthe Malayalam digital movie Moonnamathoralproduced by Benzy Martin, was distributed via satellite to cinemas, thus becoming the first Indian digital cinema. Regardless of how the DCP arrives, it first needs to be copied onto the internal hard drives of the server, usually via a USB port, a process known as "ingesting".
Keys are time-limited and will expire after the end of the period for which the title has been booked. For these reasons all projectors intended to be sold to theaters for screening current release movies must be approved by the DCI before being put on sale.
On the other hand, Digital projection projectors are around 10 times more expensive, have a much shorter life expectancy due to the developing technology already technology has moved from 2K to 4K so the pace of obsolescence is higher.

David Hancock claims that the total number of digital screens worldwide was 36, up from 16, at end or a growth rate of RGB laser projection for digital cinema: In a study, the Academy of Motion Picture Arts and Sciences found the cost of long-term storage of 4K digital masters to be "enormously higher—up to 11 times that of the cost of storing film masters.
They are also locked to the hardware server and projector that is to screen the film, so if the theatre wishes to move the title to another screen or extend the run, a new key must be obtained from the distributor. Two levels of resolution for both content and projectors are supported: No current digital medium—be it optical discmagnetic hard drive or digital tape—can reliably store a motion picture for as long as a hundred years or more something that film—properly stored and handled—does very well.
