‘DCP’ is the abbreviation for ‘Digital Cinema Package’. As the word ‘Package’ suggests, a DCP is a collection of files rather than a single file.
A DCP basically consists of two categories of elements:
- media assets (video, audio, subtitles)
- index files, referring to those media assets
The term DCP has been defined by the DCI, The Digital Cinema Initiatives, LLC in their recommendations for packaging of contents for Digital Cinema.
