Digital cinema

Digital cinema refers to the use of digital technology to distribute or project motion pictures as opposed to the historical use of motion picture film. A movie can be distributed via hard drives, the Internet, dedicated satellite links or optical disks such as Blu-ray Discs. Digital movies are projected using a digital projector instead of a conventional film projector. Digital cinema is distinct from high-definition television and is not dependent on using television or high-definition video standards, aspect ratios, or frame rates. In digital cinema, resolutions are represented by the horizontal pixel count, usually 2K (2048×1080 or 2.2 megapixels) or 4K (4096×2160 or 8.8 megapixels).

As digital cinema technology has improved in early 2010s, most of the theaters across the world have converted to digital.

History

Digital media playback of hi-resolution 2K files has at least a 20-year history with early video data storage units (RAIDs) feeding custom frame buffer systems with large memories. Content was usually restricted to several minutes of material. Transfer of content between remote locations was slow and had limited capacity. It wasn't until the late 1990s that feature-length projects could be sent over the 'wire' (Internet or dedicated fiber links).

Canon Cinema EOS

The Canon Cinema EOS (Cinema Electro-Optical System) autofocus digital photographic and cinematographic SLR and mirrorless interchangeable lens camera system was introduced in late 2011 with the Canon EOS C300 and followed by the Canon EOS C500 and Canon EOS 1D C in early 2012.

History

Cinema EOS is a branch off from the existing EOS line of cameras that date back to 1987 with the introduction of the analog Canon EOS 650. With many Canon DSLRs adding motion video capabilities starting with the Canon EOS 5D Mark II in 2008, Canon decided to focus on making cameras specially designed for motion video instead of just producing still video cameras with some motion video capabilities.

The Cinema EOS line started in late 2011, with the introduction of the C300, a motion video camera with a mirrorless design and Super 35 sensor, and new CN-E lenses (with both Canon EF and Arri PL mounts). The announcement also unveiled an upcoming Canon camera that would feature 4K motion video capabilities in a DSLR body. The demonstration of a prototype device from Canon was a rarity and was seen as a sign of their intent to enter the new still and motion camera market.
