In the area of Digital Cinema no more film reels will be sent to movie theaters. The DCP (Digital Cinema Package) is the replacement for film reels and contains digital film and audio data as well as subtitles for different languages. In order to ensure that every DCP can be shown in any movie theater worldwide, SMPTE and ISO standards were brought to its way under cooperation of the Fraunhofer IIS. All manufacturers, whose devices are compliant to these accepted specifications, will playback standard-compliant DCPs.
SOFTWARE FOR DCP CREATION
The last step in the field of motion pictures productions for digital cinema is the creation of the DCP (Digital Cinema Package). With the software tool easyDCP Creator(+) Fraunhofer IIS offers an easy-to-handle solution for the creation of Interop and SMPTE compliant DCP. This tool was especially designed for small and medium-sized production companies and post houses in order to get a complete DCP for distribution to digital cinema screens with only a few clicks.

The easyDCP functionality can be integrated into other postproduction software and adapted to the existing work environment. This is achieved through an application programming interface (API) developed by Fraunhofer IIS that can be implemented as an integral part of the program, or as a plug-in alternative, in order to create, playback (for final control) and encrypt digital cinema packages, or DCPs as they are known in the industry.
Example implementations include easyDCP plug-ins for Blackmagic Design's DaVinci Resolve and Pablo Rio from Quantel.
KEY DELIVERY MESSAGES FOR DIGITAL CINEMAS
The easyDCP KDM Generator(+) enables the creation of so called Key Delivery Messages (KDM) for digital cinemas. A KDM allows for the playback of an encrypted DCP for a certain time window on a specific playback device. With this tool one can easily generate hundreds of KDMs within a single run.
Besides the KDM generation tool we offer the creation of a personalized and DCI-compliant digital signature for all our easyDCP KDM Generator(+) customers. This enables you to sign your generated KDMs and your customers can feel certain that your KDMs are trustworthy.
It’s as simple as that:
- loading of the distribution KDM (DKDM) or Fraunhofer Digest
- choose the folder with all playback-server-certificates

Most film producers and distributors rely on digital cinema encoding facilities to produce and quality control check a digital cinema package before release. Facilities follow strict guidelines set out in the DCI recommendations to ensure compatibility with all digital cinema equipment. For bigger studio release films, the facility will usually create a DCDM (Digital Cinema Distribution Master), a DCDM is the post-production step prior to a DCP, and a DCP can be encoded directly from a DCDM.
The DCP format is also used to store stereoscopic (3D) contents. In this case, 48 frames exist for every second - 24 frames for the left eye, 24 frames for the right. Depending on the projection system used, the left eye and right eye pictures are either shown alternatively (double or triple flash systems) at 48 fps or, on 4k systems, both left and right eye pictures are shown simultaneously, one above the other, at 24 fps. In triple flash systems, active shutter glasses are required whereas optical filtering such as circular polarization is used in conjunction with passive glasses on polarized systems.
The AES encryption is applied to all files. The encryption keys are generated and transmitted via a KDM (Key Delivery Message) to the projection site. KDMs are XML files containing encryption keys that can be used only by the destination device. A KDM is associated to each playlist and defines the start and stop times of validity for the projection of that particular feature.
HOW DO WE PROTECT CONTENT
Digital supports a set of proprietary technologies to protect the content of our Products.
These technologies are:
- AES encryption: This allows any supported codec to be encrypted. The DCP Player will then need a D-Key generated for that content on that DCP Player before it can be played.
- Watermarking: This imprints a small visual mark into the video stream that can be pickup up of pirated content and used to work out where and when the content was pirated
- The DCP KDM (Key Delivery Messages) Generator enables the creation of so called Key Delivery Messages (KDM) for digital cinemas. A KDM allows for the playback of an encrypted DCP for a certain time window on a specific playback device. Supports distribution KDM (DKDM).
This device is installed in front of projection lens and acts as a light gate for a projector, when this device is activated this device overlay an infrared noise on the projection screen, Infrared rays are not visible to human eye but visible to the camera, so it can’t successfully capture clear image. The projection screen. This device is directly activate from the DCP Player, when the DCP content is played. In this way we can prevent piracy in theatres.
DCP DELIVERY METHODS
The most common method uses a specialist hard disk designed specifically for digital cinema servers to ingest from. We are using AES encrypted Solid State Drive (SSD) to deliver the content. Other less common methods adopt a full digital delivery, using either dedicated satellite links or high speed Internet connections.
FILES WE SUPPORT
The frames should be in DPX/TIFF (we are supporting up to 16Bit color space per channel) The audio file should be in Wave/Linear PCM format (we are supporting up to 16 Tracks) * 5.1/7.1 Mix, Auro 3D, Atmos.
DCP OUTPUT FILE SIZE
- 145min 2K/24fps DCP max 300GB file size
- 145min 4K/24fps DCP max 525GB file size
- 145min 3D 2K/48fps DCP max 600GB file size
