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 JTC1) for the Standards Council of Canada (SCC), the ISO 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 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
The concepts and protocols of this part of ISO/IEC 138 18 (DSM-CC) provide the general capability to browse, select, download, and control a variety of bit stream types. DSM-CC also provides a mechanism to manage network and application resources through the concept of a Session, an associated collection of resources required to deliver a Service. The Session complements a Service Domain, a collection of interfaces to browse and select services, and control the delivery of bit streams.
DSM-CC defines the syntax and semantics for a set of User-to-Network and User-to-User protocols:
- DSM-CC Message Header
- U-N Configuration messages
- U-N Session messages and flow diagrams for Session and Resource management
- U-N Download messages
- U-N Switched Digital Broadcast Channel Change Protocol
- U-N Pass Thru messages
- The transport of DSM-CC U-N messages using ISO/IEC 13818-1.
- The transport of generic IP messages using DSM-CC sections and ISO/IEC 138 18- 1, clause 9
- U-U Remote Procedure Call
- U-U Session interface
- U-U Download interface
- U-U Object Carousel interface
- U-U Local Object interface
- U-U Stream Descriptors
