Digital cinema refers to the use of digital technology to capture, distribute, or project motion pictures. A movie can be distributed via hard drives, the Internet, dedicated satellite links or optical disks such as DVDs and 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).

Famous quotes containing the word cinema:
“The cinema is not an art which films life: the cinema is something between art and life. Unlike painting and literature, the cinema both gives to life and takes from it, and I try to render this concept in my films. Literature and painting both exist as art from the very start; the cinema doesn’t.”
—Jean-Luc Godard (b. 1930)
