UltraViolet (UV) is a free, cloud-based, digital rights library that allows users of digital home entertainment content to stream and download purchased content to multiple platforms and devices. The UltraViolet ecosystem embraces a "buy once, play anywhere" approach that allows users to store digital proofs-of-purchase in an account to enable playback of purchased content on different devices, and through different streaming services. UltraViolet also allows users to share their library with up to 5 additional people, and 12 different devices, with up to three simultaneous streams.
UltraViolet is deployed by the Digital Entertainment Content Ecosystem  an alliance of 85 companies that includes film studios, retailers, consumer electronics manufacturers, cable TV companies, ISPs, network hosting vendors, and other Internet systems and security vendors, with the notable exceptions of Disney and Apple.

Jan 22: DECE launched a completely revamped UltraViolet website with new features, such as the ability to delete films from the user's collection.
Content consumers create a free UltraViolet account, either through a participating UltraViolet service provider, or through the UltraViolet website. An UltraViolet account is a Digital Rights Locker where licenses for purchased content are stored and managed irrespective of the point of sale. The Ultraviolet account holder is allowed to share their library with 5 other users, which are called members.
Consumers can acquire UltraViolet rights by purchasing a physical disc that includes an UltraViolet activation code, by purchasing a movie directly from an electronic retailer, or by using a disc to digital service. This service allows a consumer to scan a physical disc to verify ownership, and then add it to their UltraViolet collection for a small fee. Several retailers now offer this service.
Consumers can then stream or download their UltraViolet content from a participating retailer. Participating retailers are listed in the table below.
UltraViolet does not store files, and is not a "cloud storage" platform. Only the rights for purchased content are stored on the service. UltraViolet only coordinates and manages the licenses for each account, but not the content itself. The content may be obtained in any way, in its multi-DRM container format. By creating a digital-rights locker rather than a digital media storage locker, UltraViolet bypasses the cost of storage and bandwidth used when the media is accessed and passes that cost on to various service providers. In addition, by only managing the rights and licensing of content, UltraViolet insulates itself from future technological advances, allowing users to keep watching content they have purchased.
Walt Disney and its wholly owned studios are not members of DECE, and do not release any of their films with UltraViolet rights. On February 24 The Walt Disney Company launched its own competing digital movie locker called Disney Movies Anywhere that allows any Disney movie purchased or redeemed in iTunes to be played via the web or in an IOS app. Disney also includes what it calls Digital Copy Plus on its new releases, Digital Copy Plus is a redemption code that works on Amazon Instant, Vudu, iTunes, or Google Play. Non-participation in the DECE consortium does not prohibit Disney from releasing films with UltraViolet rights. In 2012 Disney's CEO Bob Iger said the studio had not ruled out UltraViolet participation, but were taking a "wait-and-see approach" and that it was too early to make conclusions.
UltraViolet content is available from many existing movie streaming services, using their existing streaming and DRM technologies. Some services offer downloads that can be saved on notebook PC's, tablets, gaming consoles, or phones for offline viewing. Below is a table of all the streaming providers and the countries they serve.
Files can also be streamed over the Internet to an unlimited number of devices, depending on the content license rights held by the streaming provider. Up to three streams can be simultaneously transmitted. CFF Compatible devices will include set-top boxes as well as Internet-enabled devices such as computers, game consoles, Blu-ray Disc players, Internet TVs, smartphones and tablets.
|United States||Canada||United Kingdom||Australia||New Zealand||France||Germany||Ireland||Switzerland||Resolution||Disc to Digital|
|Vudu||SD, HD, HDX|
|Target Ticket||SD, HD|
UltraViolet downloads, better known as the Common File Format, are not available as of Jan 1, 2013. Streaming providers who are UltraViolet ready are able to offer their own proprietary downloads. These downloaded copies are unable to be copied from one device to another, and are not cross-platform.
When the UltraViolet Common File Format is deployed, downloaded files will be able to be copied between devices, stored on physical media (e.g. DVDs, SD cards, flash memory) or cloud services, and can then be played on any UltraViolet player registered to the household account, but it will not play on devices which are not compatible with UltraViolet CFF.
The Common File Format uses the Common Encryption (CENC) system. This format is based on the ISO Base File Format, and ensures that a consistent set of codecs, media formats, DRMs, subtitling, and other kinds of data, are used across the whole UltraViolet ecosystem. The CFF uses the .uvu file extension. Because every UltraViolet title should arrive in this format, it will generally play on any UltraViolet registered device. The format is based on existing standards from MPEG, SMPTE, and others, and was originally derived from the Microsoft Protected Interoperable File Format (PIFF) specification. The goal was to avoid the problem of different file formats for different players and to make it possible to copy files from player to player.
There are two profiles for files and players: standard definition (SD) and high definition (HD). SD players can play only SD files. HD players can play both SD and HD files.
Much of the work done by DECE is being adopted by MPEG in updates to the MPEG-4 container format and as part of the MPEG Dynamic Adaptive Streaming over HTTP (DASH) format. Therefore, the common file format can be used in other systems and is expected to become broadly deployed.
UltraViolet files use the fragmented MPEG-4 container format (fMP4, technically known as ISO/IEC 14496-12 and often called an ISO container, not to be confused with an ISO disk image.)
UltraViolet files are not required to be encrypted, but it is expected that they usually will be. The files are encrypted using AES keys, which are then protected using each of the required DRM systems, with the DRM-specific information placed in the header. Both ISO scheme (PSSH/CENC) and IPMP frameworks are allowed. A player device only needs to implement one DRM.
UltraViolet files use H.264/AVC video (ISO/IEC 14496-10). Multiple resolutions, aspect ratios, and frame rates are supported. Only progressive-scan video is allowed.
UltraViolet files use stereo MPEG-4 AAC LC audio (ISO/IEC 14496-3) as a required base format, with optional multi-channel AAC, HE AAC v2 (optionally with MPEG surround), Dolby Digital, Dolby Digital Plus, Dolby TrueHD (MLP), DTS, DTS HD, DTS Master Audio, and DTS Express (low bit rate).
UltraViolet files uses SMPTE Timed Text (SMPTE TT), which is in turn based on the W3C Timed Text Markup Language (TTML). TT incorporates both Unicode text and PNG graphics for captions, subtitles for the deaf and hard of hearing (SDH), and other types of subtitles and subpictures such as sign language and written commentaries.
UltraViolet initially selected five DRM technologies allowing restrictions management on a broad range of devices: televisions, set-top-boxes, DVD & Blu-ray Disc players, games consoles, PC, tablets and smartphones.
The selected DRM technologies are:
Using the Common Encryption technology, any of these DRMs can be used to play the same file. There is no need to download another version to use a different DRM. The same file works everywhere (for a given screen size).
