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

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

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

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

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

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

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

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

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

Structure of ISAN w/Version (3) Construction of ISAN w/Version Info

Structure of V-ISAN (4) Construction of ISAN Check Digits

Registration of ISAN ISAN International Agency (ISAN-IA) Established by ISO standard — 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

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 Registration Now Open Back stock currently being entered  From AGICOA database

Registration of ISAN Version 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

Registration of ISAN Version 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

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

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

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

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

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
