CSA ISO/IEC 13522-1:00 (R2019)

CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTCI) for the Standards Council of Canada (SCC), the IS0 member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication, For a listing, refer to the CSA Information Products catalogue or CSA lnfo Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by these Committees and has been approved as a National Standard of Canada by the Standards Council of Canada. Scope This part of ISO/IEC 13522 specifies the coded representation of final-form multimedia and hypermedia information objects that are interchanged as units within or across services and applications, by any means of interchange (e.g. storage, local area network, wide area telecommunication, broadcast telecommunications or broadcast networks). These objects, called MHEG objects, define the structure of a multimedia presentation. These objects provide the following functionalities: - final-form representation, - systems with minimal resources, - interactivity and multimedia synchronization, - real-time presentation, and - real-time interchange, as a common base for many multimedia and hypermedia applications. This part of ISO/IEC 13522 defines: - the specifications of the MHEG objects without regard for the underlying representation coded representation, - the base-coded representation, using the ASN-1 representation. (Other types of coded representation may be specified in other parts of ISO/IEC 13522.) 1.1 Specificity of the Scope Since it is expected that a wide range of recommendations, standards, and using applications will be users of this part of ISO/IEC 13522, the scope focuses on the generic structuring aspects. This part of ISO/IEC 13522 recognizes the semantics implied by the specification of the MHEG objects but does not enforce any semantic interpretation by the using application. 1.2 Issues Outside the Scope of this Part of ISO/IEC 13522 The scope excludes any standardization of models, services, systems, protocols or applications that make use of MHEG objects. Integration of MHEG objects within these models, services, systems, protocols or applications, or interworking, may be defined by other standards. The coded representation of content data is not in the scope of this part of ISO/IEC 13522.
