Methods for projecting cinematic materials digitally first set forth in the Digital Cinema System Specification, a proposal authored by the Digital Cinema Initiatives (DCI), a group of six Hollywood studios, in 2005. Traditional film containing the movie is replaced by an electronic copy contained on a storage device. Instead of projecting light through print film, digital cinema uses technologies such as DLP and LCOS to accomplish the task. The DCI has mandated industry-wide compliance with digital projection standards by 1 January 2014.
