  2. Agenda • Definition of ISAN • Applications of ISAN • ISAN Version Extension • Applications of ISAN Version Info • Structures of ISAN & V-ISAN • ISAN & V-ISAN Registries

  3. Definition of ISAN • International Standard Audiovisual Number • Unique, Registered Identifier • Individual works • Series & their episodes • Identifies Completed Works • Motion pictures • Television programs • Other works having moving images • Includes Associated Audio & Data

  4. Applications of ISAN • Unique, Registered Identifier for Works • Compared to unregistered identifiers such as UMID • Can Serve as Key to Related Databases • Some major rights ownership • Cast membership • Crew membership • Residuals obligations • Production details • Other metadata • Permanently Assigned, Registered, & Published

  5. ISAN Version Extension • Unique, Registered Identifiers • Versions of Standalone Works • Versions of Episodes • Versions Indicate Editorial Differences • Some major, most minor rights ownership • Actual cutting of the work • Associated languages in audio • Associated languages in captions / subtitles • Associated data elements • Different video formats / audio formats

  6. Applications of ISAN Version • Identification of Content for Release / Distribution • E.g., if it matters which tape or file is played back • Automation of Release Procedures • Automation of Quality Control Procedures • Automation of Auditing Procedures • Automation of Program Schedule Creation • Automation of Program Listings Data Collection

  7. Structure of ISAN • “Dumb” Number – No Meaning • Root & Episode Portions • Root identifies individual works & series • Episode identifies works within series • 64-bit Number • 48 bits for Root • 16 bits for Episode • Expressed as 16 hexadecimal digits

  8. Structure of ISAN (2) • Check Digit Added for Human Interaction • For display of ISAN • For manual entry of ISAN • Structure of ISAN for Human Interaction • ISAN RRRR-RRRR-RRRR-EEEE-X • Capacity of Root & Episode Portions • Root = 281,474,976,710,656 identifiers • Episode = 65,535 identifiers • Objective is Capacity for 150 Years of Use

  9. Structure of ISAN w/Version • “Dumb” Number – No Meaning • Version Portion Added to ISAN • ISAN identifies Root & Episode of works • Version portion differentiates individual versions • 96-bit Number • 48 bits for Root • 16 bits for Episode • 32 bits for Version • Expressed as 24 hexadecimal digits

  10. Structure of ISAN w/Version (2) • Check Digits Added for Human Interaction • For display / manual entry of V-ISAN • Original ISAN check digit + Version check digit • Structure of ISAN for Human Interaction • ISAN RRRR-RRRR-RRRR-EEEE-X-VVVV-VVVV-Y • Capacity of Root, Episode & Version Portions • Root = 281,474,976,710,656 identifiers • Episode = 65,535 identifiers • Version = 4,294,967,296 identifiers • Capacity Objective Remains 150 Years of Use

  11. Structure of ISAN w/Version (3) • Construction of ISAN w/Version Info

  12. Structure of V-ISAN (4) • Construction of ISAN Check Digits

  13. Registration of ISAN • ISAN International Agency (ISAN-IA) • Established by ISO standard — 15706 • Single Database for Registry • Maintained by ISAN International Agency • Multiple ISAN Registration Agencies • Provide registration services to registrants • Provide access to ISAN database information • May maintain copies of ISAN database • Two agencies already appointed

  14. Registration of ISAN (2) • ISAN Database Contains Descriptive Info • Establishes uniqueness of works • Permits obtaining basic info about works • Provides links to additional information • ISAN Database Accessible On Line • www.isan.org • Registration Now Open • Back stock currently being entered • From AGICOA database

  15. Registration of ISANVersion Extension (V-ISAN) • V-ISAN Authority • Provides accreditation of V-ISAN Agencies • Multiple V-ISAN Registration Agencies • Provide all ISAN & V-ISAN services • Provide registration services to registrants • Provide access to ISAN/V-ISAN database information • Maintain V-ISAN distributed database • Multiple mirrored copies around the world

  16. Registration of ISANVersion Extension (V-ISAN) (2) • Resolution Service Providers • Maintain associated metadata for V-ISAN • Record points to one as designated RSP • Provide mechanism for obtaining info • Since version info not published by agencies • Can be organizations registering versions • Self publication of metadata • Must respond to queries using standard protocol

  17. ISAN Characteristics • Predictable • Assignable, useful in contracts, many other uses – prior to production • External • Suitable for interchange between organizations • Enumerable • Provides exhaustive list • Allows determination of database completeness

  18. ISAN Characteristics (2) • Inspectable • Allows identification of all versions of a work • Allows identification of all versions of all episodes of a series • Permanent • Registry external to any producing organization • Will survive any changes in producing / owning organizations

  19. Status of ISAN/V-ISAN Standards • ISAN is ISO Standard • ISO 15706 Part 1 • ISAN Version Extension in Balloting Process • ISO 15706 Part 2 (V-ISAN) • ISAN Operational Guidelines in Balloting • ISO 20925

  20. Issues Regarding ISAN / V-ISAN • ISAN Scope Limited to Sequences of Images • Related images with or without sound • Intended to be made visible as moving images • No Support for Audio- or Data-Only Works • Some covered by other ISO registration systems • Some not covered by ISO registrations • Components of Works Can Have V-ISAN • Helps in production / distribution • Work Needed to Expand ISAN Scope • Or alternative registration mechanisms needed

  21. Application Issues re: V-ISAN • Can Be Used to Identify Show Elements • Main work of show • Commercials/promos inserted into show • Useful for operations purposes • Possibility of Enabling Commercial Killers • If IDs of commercials/promos are broadcast • Encryption needed if all IDs broadcast • Encryption must not expose changes in IDs • Only main work identified in the clear
