National bodies that are members of IS0 or IEC parti

19、cipate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmenta

20、l and non-governmental, in liaison with IS0 and IEC, also take part in the work. International Standards are drafted in accordance with the rules given in the ISOAEC Directives, Part 3. In the field of information technology, IS0 and IEC have established a joint technical committee, ISOAEC JTC 1. Dr

21、aft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISOAEC 13818-l 0 was prepared by Joint Technica

25、M-CC) 1 Scope This part of ISO/IEC 138 18 defines compliance to Data Storage Media Command and Control (DSMCC) standard in 2 steps: the static review and the dynamic review as defined in ISO/IEC 9646 Conformance Testing standard 1, 2, 31. The static review requirements are specified in clause 4 of t

26、his part of ISO/IEC 138 18 in the form of Protocol Implementation Conformance Statement (PICS) proforma. The ATS used for dynamic review is described in clause 5. This part of ISO/IEC 138 18 does not specify all the requirements with which terminal equipment intended for use in conjunction with mult

27、imedia information retrieval services has to comply. In particular, this part of ISO/IEC 138 18 does not specify (lower layer) protocols to be used to deliver/transport DSM-CC protocol data units. Neither does it specify requirements related to safety, protection, and electromagnetic compatibility (

28、EMC) of the equipment, or regulatory requirements with which such equipment may be required to comply. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO/IEC 138 18. At the time of publication, the editio

29、ns indicated were valid.

35、ts of ISO/IEC 138 18-6. The PICS proforma is in compliance with the relevant requirements, and in accordance with the relevant guidance for a PICS proforma, g oiven in IS0 9646-2. Detail of the use of this proforma is provided in this part of ISO/IEC 13818. Implementations claiming conformance to IS

36、O/IEC 138 18-6 shall complete the proforma as part of the conformance requirements. The DSM-CC specification is a collection of protocols and interfaces that accomplish the control of bit streams. DSM-CC can be viewed as consisting of two broad categories of functionality; User-to-User and User-to-N

37、etwork. Each of these categories is further divided into functional groups. The following table defines the functional groups of DSM-CC User-to-Network and provides a brief description of each group: Table 1 - DSM-CC User-to-Network Functional Groups Functional Group U-N Configuration Description A

39、 A set of messages which are used to download information to a DSM-CC User. A set of messages which are used by the User to request stream switching by the Network. A set of messages which are used to communicate between Users through the Network and outside of a session. DSM-CC Message Header All D

40、SM-CC UN messages begin with the DSM-CC Message Header, which contains information about the type of message being passed The following table defines the functional groups of DSM-CC User-to-User and provides a brief description of each group: Table 2 - DSM-CC User-to-User Functional Groups Functiona

43、method by which the messages and data shall be transported when these messages or data are transported in an MPEG-2 Systems Transport. This clause does not specify transport methods other than MPEG-2 Systems Transport. An implementation may be compliant with any or all of the functional groups as re

44、quired by that implementation. 4.1 ISOllEC Protocol Versions Implemented ISO/IEC 138 18-6 identifies the protocol version through the use of the dsmccType field in the message header of User to Network messages. If the protocol is modified, the dsmccType for that class of messages shall be assigned

45、a new value. The following table (from ISO/IEC 138 18-6 clause 2, table 2-2) identifies the current versions of the DSM-CC protocol: Table 3 - DSM-CC Protocol Versions dsmccType 0x00 0x01 0x02 0x03 0x04 0x05 0x06-Ox7F 0x80-OxFF Description ISO/IEC 13 8 18-6 Reserved Identifies the message as an ISO/

46、IEC 138 18-6 User-to-Network configuration message. Identifies the message as an ISO/IEC 138 18-6 User-to-Network session message. Identifies the message as an ISO/IEC 138 18-6 Download message. Identifies the message as an ISO/IEC 138 18-6 SDB Channel Change Protocol message. Identifies the message

47、 as an ISO/IEC 138 18-6 User-to- Network pass-thru message. ISO/IEC 13 8 18-6 Reserved. User Defined message type. For DSM-CC User-to-User, the protocol version is identified by the object version in the message header. An implementation shall be described by completing a separate PICS proforma for

48、each supported protocol version. The PICS for all versions of the protocol for which conformance is claimed, should be attached to each other, and used together. 4.2 Global Statement of Conformance Table 4 - DSM-CC Functional Units Item Does the implementation support . . .
