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.
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. Its core strength lies in its universal benefits and long-term stability.
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.

Famous quotes containing the words standard and/or number:
“If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
—Leon Trotsky (1879–1940)
“How often should a woman be pregnant? Continually, or hardly ever? Or must there be a certain number of pregnancy anniversaries established by fashion? What do you, at the age of forty-three, have to say on the subject? Is it a fact that the laws of nature, or of the country, or of propriety, have ordained this time of life for sterility?”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
