A CDE Definition
(1) Any aspect of movie making in the digital domain, including capture, editing, distribution and projection.
(2) The projection of movies in digital formats using digital projectors such as the DLP units from TI. Movie distribution has migrated from analog to digital in order to eliminate the cost of making film copies. Satellite distribution of video to theaters is also being done; however, most data transfer is accomplished by shipping external hard drives via mail, UPS or FedEx that plug into the eSATA, USB or FireWire ports of the servers in each digital projection room.
The low-cost transfer of digital movies enables distribution to small theaters that cannot justify the expense of a film copy. Digital cinema also expands a theater's offerings, allowing it to show content, such as concerts, operas and sporting events, in addition to regular movies.
Still Shot on 35mm Film
As of 2012, Hollywood movies are increasingly shot entirely in digital; however, 35mm is still used. Directors have decades of experience shooting film and understand the nuances of the art. The 35mm film is then scanned at a high resolution and converted to digital. See digital intermediate.
"Digital cinema" refers to digital formats in general such as MPEG, JPEG 2000 and Windows Media. For example, MPEG-2 is widely used for pre-show videos and advertising. However, "dCinema" refers to the DCI (Digital Cinema Initiatives) specification that uses JPEG 2000 compression and the MXF packaging format. It also includes content protection and timing data. For more information about the DCI format, visit www.dcimovies.com.
