Digital cinema refers to the adoption of digital technology within the film industry to distribute or project motion pictures as opposed to the historical use of reels of motion picture film, such as 35 mm film. Whereas film reels have to be shipped to movie theaters, a digital movie can be distributed to cinemas in a number of ways: over the Internet or dedicated satellite links, or by sending hard drives or optical discs such as Blu-ray discs.
Serial digital interface (SDI) is a family of digital video interfaces first standardized by SMPTE in 1989. For example, ITU-R BT.656 and SMPTE 259M define digital video interfaces used for broadcast-grade video. A related standard, known as high-definition serial digital interface (HD-SDI), is standardized in SMPTE 292M; this provides a nominal data rate of 1.485 Gbit/s.
1080p is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes referred to as 2K resolution, other sources differentiate between 1080p and (true) 2K resolution.
Digital Cinema Initiatives, LLC (DCI) is a consortium of major motion picture studios, formed to establish specifications for a common systems architecture for digital cinema systems.
SxS (S-by-S) is a flash memory standard compliant to the Sony and SanDisk-created ExpressCard standard. According to Sandisk and Sony, the cards have transfer rates of 800 Mbit/s and burst transfer rate of up to 2.5 Gbit/s over the ExpressCard's PCI Express interface. Sony uses these cards as the storage medium for their XDCAM EX line of professional video cameras.
The following is a list of H.264/MPEG-4 AVC products and implementations.
Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices, and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay. It is conveyed over various types of baseband digital video interfaces, such as HDMI, DVI, DisplayPort and SDI. Standards also exist for the carriage of uncompressed video over computer networks.
4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 3840 × 2160 with a 16:9 aspect ratio is the dominant 4K standard, whereas the movie projection industry uses 4096 × 2160.
A Digital Cinema Package (DCP) is a collection of digital files used to store and convey digital cinema (DC) audio, image, and data streams.
GoPro, Inc. is an American technology company founded in 2002 by Nick Woodman. It manufactures action cameras and develops its own mobile apps and video-editing software. Founded as Woodman Labs, Inc, the company eventually focused on the connected sports genre, developing its line of action cameras and, later, video editing software. It is based in San Mateo, California.
Doremi Laboratories, Inc., often shortened to Doremi Labs, was a developer and manufacturer of digital servers and format converters for the digital cinema, broadcast, post-production and professional A/V markets. It was established in 1985 in Burbank, California, United States, and was absorbed into Dolby Laboratories in a 2014 acquisition.
The Sony Alpha 57 is a Digital single-lens reflex camera that replaced the A55 in 2012. The camera features an electronic viewfinder and a translucent mirror. The main advantage of a translucent mirror is that it needn't flip up out of the way when taking a picture in order to expose the sensor, but the camera can focus and capture images simultaneously. The camera's 15-point autofocus system can be set to single, continuous or automatic and is arranged towards the centre. The 12-fps burst mode is available only in "speed priority" mode but can reach up to 5.5 fps burst rate in combination with any other settings.
XAVC is a recording format that was introduced by Sony on October 30, 2012. XAVC is a format that will be licensed to companies that want to make XAVC products.
CineAsset is a complete mastering software suite by Doremi Labs that can create and playback encrypted and unencrypted DCI compliant packages from virtually any source. CineAsset includes a separate "Editor" application for generating Digital Cinema Packages (DCPs). CineAsset Pro adds the ability to generate encrypted DCPs and Key Delivery Messages (KDMs) for any encrypted content in the database.
Apple ProRes is a high quality, "visually lossless" lossy video compression format developed by Apple Inc. for use in post-production that supports video resolution up to 8K. It is the successor of the Apple Intermediate Codec and was introduced in 2007 with Final Cut Studio 2. Much like the H.26x and MPEG standards, the ProRes family of codecs use compression algorithms based on the discrete cosine transform (DCT). ProRes is widely used as a final format delivery method for HD broadcast files in commercials, features, Blu-ray and streaming.
CinePlayer is a software based media player used to review Digital Cinema Packages (DCP) without the need for a digital cinema server by Doremi Labs. CinePlayer can play back any DCP, not just those created by Doremi Mastering products. In addition to playing DCPs, CinePlayer can also playback JPEG2000 image sequences and many popular multimedia file types.
Ultra-high-definition television today includes 4K UHD and 8K UHD, which are two digital video formats with an aspect ratio of 16:9. These were first proposed by NHK Science & Technology Research Laboratories and later defined and approved by the International Telecommunication Union (ITU).
Ultra HD Forum is an organization whose goal is to help solve the real world hurdles in deploying Ultra HD video and thus to help promote UHD deployment. The Ultra HD Forum will help navigate amongst the standards related to high dynamic range (HDR), high frame rate (HFR), next generation audio (NGA), and wide color gamut (WCG). The Ultra HD Forum is an industry organisation that is complementary to the UHD Alliance, covering different aspects of the UHD ecosystem.
The Blackmagic URSA is a digital movie camera developed and manufactured by Blackmagic Design, released on August 8, 2014. It is the first camera to be user-upgradeable for additional equipment manufactured by Blackmagic and other third-party makers.
