Refers to the digital distribution and projection of cinema material. With virtually all films now using the DI process, the next step is to distribute and replay digital material. Thanks to the DCI’s Digital Cinema System Specification (July 2005), a set of standards is in place and the majority of cinemas worldwide are now converted to digital.
The digital cinema chain includes DCI-compliant equipment for mastering which generally uses JPEG 2000 compression encoding and high strength encryption. At the cinema players and digital projectors include decryption, image decoding and predominantly DLP, D-ILA technologies to display the images and provide consistently high quality viewing on large screens – no matter how many times the movie is shown.
Digital Cinema offers new methods for duplication, high-level security, efficient duplication distribution and greater flexibility. In addition, stereo cinema (a.k.a. 3D) is easy to set up and present using just one projector (not two), along with a left and right eye selective viewing system.
Many digital cinemas can also show live (or recorded) footage originating in HDTV. These presentations typically include live sports, big events and theatrical performances from around the world, creating new markets for cinemas.
