International Standard Audiovisual Number

International Standard Audiovisual Number (ISAN) is a unique identifier for audiovisual works and related versions, similar to ISBN for books. It was developed within an ISO (International Organisation for Standardisation) TC46/SC9 working group. ISAN is managed and run by ISAN-IA.

ISAN's logo


The ISAN standard (ISO standard 15706:2002 & ISO 15706-2) is recommended or required as the audiovisual identifier of choice for producers, studios, broadcasters, Internet media providers and video games publishers who need to encode, track, and distribute video in a variety of formats. It provides a unique, internationally recognized and permanent reference number for each audiovisual work and related versions registered in the ISAN system.

ISAN identifies works throughout their entire life cycle from conception, to production, to distribution and consumption.

ISANs can be incorporated in both digital and physical media, such as theatrical release prints, DVDs, publications, advertising, marketing materials and packaging, as well as licensing contracts to uniquely identify works.

The ISAN identifier is incorporated in many draft and final standards such as AACS, DCI, MPEG, DVB, and ATSC.[1] The identifier can be provided under descriptor 13 (0x0D) for Copyright identification system and reference within an ITU-T Rec. H.222 or ISO/IEC 13818 program.

Number format

Example ISAN with two-dimensional barcode

The ISAN is a 12 byte block comprising three segments: a 6 byte root, a 2 byte episode or part, and a 4 byte version.

Length Name Type Default
48 bits isan_root uimsbf varies
16 bits root_part uimsbf 0
32 bits part_version uimsbf 1

uimsbf: unsigned integer, most significant bit first

A root is assigned to a core work by the ISAN-IA.

If a root has subsequent film parts (i.e., sequels) or television episodes then the root_part is incremented and started at a point defined by the producing studio. (i.e., relates to the production number)

If a root_part has been modified in some way—for example, dubbing, 24/30/25 frame conversions and subtitling the work into other languages—can have different versions. Common uses are when the native North American 30/1001 frame version is set to one, the 25 frame conversion for PAL compatible markets is set to two.

When the 12 byte ISAN is represented in hexadecimal form it has 24 digits, for example: 000000018947000000000000. However, a printed ISAN designed for human reading always begins with the ISAN label, appears with hyphens to separate the number into more manageable groups of digits, and adds two check characters (alphanumeric) to help identify transcription errors. The resulting number appears as: ISAN 0000-0001-8947-0000-8-0000-0000-D

ISAN-IA has also developed a recommended practice for encoding the ISAN in a two-dimensional barcode 96 pixels square.

An ISAN is a centrally registered and permanently assigned reference number. The work or content it references is identified by a metadata set registered with ISAN-IA. Appointed Registration Agencies and ISAN-IA work together to prevent duplicate assignments of ISANs with the same metadata set. The ISAN metadata set includes the title (original and alternative), cast (director, actors, producer, screenwriter, etc...), type of works (movie, documentary, TV series or entertainment show, sport events, video games, etc...), duration, year of production and dozens of other fields related to the work. This metadata applies to all type of audiovisual works, including their related versions of trailers, excerpts, videos and broadcasts.

The Microsoft High Capacity Color Barcode will be used too.[2]


ISAN-IA (ISAN International Agency) is a Geneva-based non-profit association, founded in 2003, by AGICOA, CISAC, and FIAPF to run the ISAN standard.

ISAN-IA is in charge of:

  • maintaining the ISAN central repository
  • implementing, running and managing the ISAN system
  • accrediting and appointing the ISAN registration agencies worldwide
  • promoting with the help of the registration agencies, the ISAN standard to the audiovisual industry.

Confédération Internationale des Sociétés d'Auteurs et Compositeurs

The International Confederation of Societies of Authors and Composers (French: Confédération Internationale des Sociétés d'Auteurs et Compositeurs, CISAC) is an international non-governmental, not-for-profit organisation that aims to protect the rights and promote the interests of creators worldwide. It advocates for strong legal protection of copyright and authors' rights. It is the world's largest international network of authors' societies, also known as Collective Management Organisations (CMOs), copyright / royalty collection societies, collecting societies, or Performing Rights Organisations (PROs).

The president of CISAC is French electronic music composer Jean Michel Jarre, who was appointed in June 2013. His predecessor was singer/songwriter Robin Gibb of the Bee Gees, who served as President until his death in 2012. Painter Hervé Di Rosa serving as President in the interim, until the appointment of Jarre.

In 2013, the organisation expanded its Vice Presidency to four new positions, allowing for the representation of more territories and a broader range of creative repertoires. The four new Vice Presidents include: Angélique Kidjo, a Grammy award-winning performing artist and activist from Benin, Javed Akhtar, a celebrated scriptwriter, poet, lyricist from India, Marcelo Piñeyro, an Academy Award-winning producer and film director from Argentina, and Ousmane Sow, a revered sculptor from Senegal.

Currently, 238 authors' societies from 121 countries are members of CISAC. Together, these authors' societies represent music publishers and approximately four million creators and publishers from all geographic regions and all artistic fields (music, audiovisual, drama, visual arts and literature).In 2015, CISAC's member societies collected, €8.6bn in royalties from their respective national territories.

CISAC was founded in 1926. Its international headquarters are located in Neuilly-sur-Seine, France, with four regional offices based in Budapest, Hungary (European Affairs), Santiago, Chile (Latin American and Caribbean Affairs), Burkina Faso (African Affairs) and, since January 2013, Beijing, China (Asia-Pacific Affairs).

CISAC is financed by membership dues and has three official languages: English, French and Spanish.

Digital object identifier

In computing, a Digital Object Identifier or DOI is a persistent identifier or handle used to uniquely identify objects, standardized by the International Organization for Standardization (ISO). An implementation of the Handle System, DOIs are in wide use mainly to identify academic, professional, and government information, such as journal articles, research reports and data sets, and official publications though they also have been used to identify other types of information resources, such as commercial videos.

A DOI aims to be "resolvable", usually to some form of access to the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL, indicating where the object can be found. Thus, by being actionable and interoperable, a DOI differs from identifiers such as ISBNs and ISRCs which aim only to uniquely identify their referents. The DOI system uses the indecs Content Model for representing metadata.

The DOI for a document remains fixed over the lifetime of the document, whereas its location and other metadata may change. Referring to an online document by its DOI is supposed to provide a more stable link than simply using its URL. But every time a URL changes, the publisher has to update the metadata for the DOI to link to the new URL. It is the publisher's responsibility to update the DOI database. If they fail to do so, the DOI resolves to a dead link leaving the DOI useless.

The developer and administrator of the DOI system is the International DOI Foundation (IDF), which introduced it in 2000. Organizations that meet the contractual obligations of the DOI system and are willing to pay to become a member of the system can assign DOIs. The DOI system is implemented through a federation of registration agencies coordinated by the IDF. By late April 2011 more than 50 million DOI names had been assigned by some 4,000 organizations, and by April 2013 this number had grown to 85 million DOI names assigned through 9,500 organizations.


EIDR, or the Entertainment Identifier Registry, is a global unique identifier system for a broad array of audio visual objects, including motion pictures, television, and radio programs. The identification system resolves an identifier to a metadata record that is associated with top-level titles, edits, DVDs, encodings, clips, and mash-ups. EIDR also provides identifiers for Video Service providers, such as broadcast and cable networks.

As of February, 2018, EIDR contains over 1.8 million records, including 298K movies, and 794K episodes of over 25K TV series.

EIDR is an implementation of a Digital Object Identifier (DOI).

High Capacity Color Barcode

High Capacity Color Barcode (HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes. Data density is increased by using a palette of 4 or 8 colors for the triangles, although HCCB also permits the use of black and white when necessary. It has been licensed by the ISAN International Agency for use in its International Standard Audiovisual Number standard, and serves as the basis for the Microsoft Tag mobile tagging application.

The technology was created by Gavin Jancke, an engineering director at Microsoft Research. Quoted by BBC News in 2007, he said that HCCB was not intended to replace conventional barcodes. "'It's more of a 'partner' barcode', he said. 'The UPC barcodes will always be there. Ours is more of a niche barcode where you want to put a lot of information in a small space.'"

ISO 15706-2

The ISO 15706-2 is the ISO standard, an extension to the existing 2002 published standard ISO 15706:2002. The ISO 15706-2 is the Information and documentation — International Standard Audiovisual Number — Part 2: Version identifier.

ISO 15706-2:2007 establishes a voluntary system for the identification of versions of audiovisual works and other content derived from or closely related to an audiovisual work. It is based on the International Standard Audiovisual Number (ISAN) system defined in ISO 15706:2002. An ISAN combined with the version segment, as specified in ISO 15706-2:2007 constitutes an ISAN version identifier, is referred to as a V-ISAN. A V-ISAN is a registered, globally unique identifier for versions of an audiovisual work and related content.

ISO 15706-2:2007 specifies the basic systems and procedures to support the issuance and administration of V-ISANs.

ISO TC 46/SC 9

ISO TC 46/SC 9 is the ninth subcommittee of ISO technical committee 46, and is responsible for identification and description of information resources.

As of April 2008, the TC 46/SC 9 Secretariat was transferred to ANSI (U.S.A.).

International Bank Account Number

The International Bank Account Number (IBAN) is an internationally agreed system of identifying bank accounts across national borders to facilitate the communication and processing of cross border transactions with a reduced risk of transcription errors. It was originally adopted by the European Committee for Banking Standards (ECBS), and later as an international standard under ISO 13616:1997. The current standard is ISO 13616:2007, which indicates SWIFT as the formal registrar. Initially developed to facilitate payments within the European Union, it has been implemented by most European countries and numerous countries in the other parts of the world, mainly in the Middle East and in the Caribbean. As of February 2016, 69 countries were using the IBAN numbering system.The IBAN consists of up to 34 alphanumeric characters comprising: a country code; two check digits; and a number that includes the domestic bank account number, branch identifier, and potential routing information. The check digits enable a check of the bank account number to confirm its integrity before submitting a transaction.

International Securities Identification Number

An International Securities Identification Number (ISIN) uniquely identifies a security. Its structure is defined in ISO 6166. The ISIN code is a 12-character alphanumeric code that serves for uniform identification of a security through normalization of the assigned National Number, where one exists, at trading and settlement.

International Standard Book Number

The International Standard Book Number (ISBN) is a numeric commercial book identifier which is intended to be unique. Publishers purchase ISBNs from an affiliate of the International ISBN Agency.An ISBN is assigned to each edition and variation (except reprintings) of a book. For example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, and 10 digits long if assigned before 2007. The method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country.

The initial ISBN identification format was devised in 1967, based upon the 9-digit Standard Book Numbering (SBN) created in 1966. The 10-digit ISBN format was developed by the International Organization for Standardization (ISO) and was published in 1970 as international standard ISO 2108 (the SBN code can be converted to a ten-digit ISBN by prefixing it with a zero digit "0").

Privately published books sometimes appear without an ISBN. The International ISBN agency sometimes assigns such books ISBNs on its own initiative.Another identifier, the International Standard Serial Number (ISSN), identifies periodical publications such as magazines and newspapers. The International Standard Music Number (ISMN) covers musical scores.

International Standard Link Identifier

The International Standard Link Identifier (ISLI), is an identifier standard. ISLI is a universal identifier for links between entities in the field of information and documentation. It was developed by the International Organization for Standardization (ISO) and published on May 15, 2015. ISO/TC 46/SC 9 is responsible for the development of the ISLI standard.ISLI is used for identifying links between entities in the field of information and documentation. A linked entity can be physical, e.g. a print book or an electronic resource (text, audio, and video); or something abstract, e.g. a physical position within a frame of reference or the time of day.

In the context of modern information technology, the application of resources in the field of information and documentation is increasingly getting diversified. Isolated content products can no longer satisfy the ever-increasing user demand.

Using a link identifier to build links between resources in the field of information and documentation provides a basis for a combined application of resources in the field, and supports collaborative creation of content and data interoperability between systems.

The openness of the ISLI system will boost the emergence of new applications in both multimedia and other fields, which increases the value of the linked-resources.

International Standard Music Number

The International Standard Music Number or ISMN (ISO 10957) is a thirteen-character alphanumeric identifier for printed music developed by ISO.

International Standard Musical Work Code

International Standard Musical Work Code (ISWC) is a unique identifier for musical works, similar to ISBN for books. It is adopted as international standard ISO 15707. The ISO subcommittee with responsibility for the standard is TC 46/SC 9.

International Standard Number

International Standard Number may refer to:

International Standard Book Number, a unique numeric commercial book identifier based upon the 9-digit Standard Book Numbering code

International Standard Serial Number, a unique eight-digit number used to identify a print or electronic periodical publication

International Standard Name Identifier, a unique sixteen-digit number used to identify the public identities of contributors to media content

International Standard Music Number, a thirteen-character alphanumeric identifier for printed music

International Standard Audiovisual Number, a unique identifier for audiovisual works and related versions

ISWN, the abbreviation of International Standard Wine Number, a coding scheme intended to give a unique identifier for each wine worldwide

International Standard Recording Code

The International Standard Recording Code (ISRC) is an international standard code for uniquely identifying sound recordings and music video recordings. The code was developed by the recording industry in conjunction with the ISO technical committee 46, subcommittee 9 (TC 46/SC 9), which codified the standard as ISO 3901 in 1986, and updated it in 2001.

An ISRC identifies a particular recording, not the work (composition and lyrical content) itself. Therefore, different recordings, edits, and remixes of the same work should each have their own ISRC. Works are identified by ISWC. Recordings remastered without significant audio-quality changes should retain their existing ISRC, but the threshold is left to the discretion of the record company.

International Standard Serial Number

An International Standard Serial Number (ISSN) is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is especially helpful in distinguishing between serials with the same title. ISSN are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature.The ISSN system was first drafted as an International Organization for Standardization (ISO) international standard in 1971 and published as ISO 3297 in 1975. ISO subcommittee TC 46/SC 9 is responsible for maintaining the standard.

When a serial with the same content is published in more than one media type, a different ISSN is assigned to each media type. For example, many serials are published both in print and electronic media. The ISSN system refers to these types as print ISSN (p-ISSN) and electronic ISSN (e-ISSN), respectively. Conversely, as defined in ISO 3297:2007, every serial in the ISSN system is also assigned a linking ISSN (ISSN-L), typically the same as the ISSN assigned to the serial in its first published medium, which links together all ISSNs assigned to the serial in every medium.

International Standard Text Code

The International Standard Text Code (ISTC) is a unique identifier for text-based works. The ISO standard was developed by TC 46/SC 9 and published in March 2009 as ISO 21047:2009. The authority responsible for implementing the standard is The International ISTC Agency.
