scope:

The concepts and protocols of this part of ISO/IEC 13818 (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 ISODEC 13818-1, 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
