Digital technology has transformed the information flow and support infrastructure for numerous application domains, such as cellular communications. Cinematography, traditionally, a film based medium, has embraced digital technology leading to innovative transformations in its work flow. Digital cinema supports transmission of high resolution content enabled by the latest advancements in optical communications and video compression. In this paper we provide a survey of the optical network technologies for supporting this bandwidth intensive traffic class. We also highlight the significance and benefits of the state of the art in optical technologies that support the digital cinema work flow.

Digital Cinema Initiatives (DCI)

Digital Cinema Initiatives specification  is approved by seven major motion picture studios and provides the main objectives. It specifies a store-and-forward non-real-time method of distribution to the theatres ahead of playback. The data transport can be through any (satellite, fibre, and copper) method but must provide a secure environment for content as well as safeguards against corruption of data.

The content is acquired as Digital Source Master (DSM) which is then transformed as Digital Cinema Distribution Master (DCDM). This is further transformed as a Digital Cinema Package (DCP). The DCP is the standard Media Exchange Format (MXF) in which movies are delivered to theatres. The distribution can take various forms such as physical mediums like hard disks and transmission over satellite or broadband or delivered live over optical networks from a distribution centre.
