The work
21、 of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmen
22、tal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The ma
23、in task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In
24、 other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group
25、 and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the mem
26、bers of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further t
27、hree years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent right

ISO/TS 18234-10 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 278, Road transport and traffic telematics, in collaboration with ISO Technical Committee ISO/TC 204, Intelligent transport systems, in accordance with the Agreement on technical cooperatio

32、CEN ISO/TS 18234-10:2013ISO/TS 18234-10:2013(E) vi ISO 2013 All rights reservedIntroduction TPEG technology uses a byte-oriented data stream format, which may be carried on almost any digital bearer with an appropriate adaptation layer. TPEG-messages are delivered from service providers to end-users
33、 and used to transfer information from the database of a service provider to an end-users equipment. The brief history of TPEG technology development dates back to the European Broadcasting Union (EBU) Broadcast Management Committee establishing the B/TPEG project group in autumn 1997 with the manda
34、te to develop, as soon as possible, a new protocol for broadcasting traffic and travel-related information in the multimedia environment. TPEG technology, its applications and service features are designed to enable travel-related messages to be coded, decoded, filtered and understood by humans (vis
35、ually and/or audibly in the users language) and by agent systems. One year later in December 1998, the B/TPEG group produced its first EBU specifications. Two Technical Specifications were released. ISO/TS 18234-2, described the Syntax, Semantics and Framing Structure, which is used for all TPEG app
36、lications. ISO/TS 18234-4 (TPEG-RTM) described the first application, for Road Traffic Messages. Subsequently, CEN/TC 278/WG 4, in conjunction with ISO/TC 204, established a project group comprising the members of B/TPEG and they have continued the work concurrently since March 1999. Since then two
37、further parts were developed to make the initial complete set of four parts, enabling the implementation of a consistent service. ISO/TS 18234-3 (TPEG-SNI) describes the Service and Network Information Application, which should be used by all service implementations to ensure appropriate referencing
38、 from one service source to another. ISO/TS 18234-1 (TPEG-INV), completes the series, by describing the other parts and their relationship; it also contains the application IDs used within the other parts. Additionally ISO/TS 18234-5 the Public Transport Information Application (TPEG-PTI) and ISO/TS
39、 18234-6 (TPEG-LRC), were developed. TPEG applications are developed using UML modelling and a software tool is used to automatically select content which then populates this TS. Diagrammatic extracts from the model are used to show the capability of the binary coding in place of lengthy text descri
40、ptions; the diagrams do not necessarily include all relevant content possible. This Technical Specification describes the binary data format of the on-air interface of the Conditional Access Information application, (TPEG-CAI) with the technical version number TPEG-CAI_1.0/001. CAI application The b
41、asic concept behind the CAI application is to transport CAI in separate TPEG service components of a dedicated application type and to define an SNI table that contains the link between scrambled content and related CAI.

42、2013 All rights reserved 1Intelligent transport systems Traffic and travel information via transport protocol experts group, generation 1 (TPEG1) binary data format Part 10: Conditional access information (TPEG-CAI) 1 Scope This Technical Specification contains the definition of the TPEG Conditional
43、 Access Information (CAI) application. It enables dedicated conditional access data, such as management messages (e.g. Control Words and Entitlement Control Messages) to be delivered to recipient client devices. This TPEG application is designed for a service provider to: establish setup, prolongati
44、on or revocation of services to a specific client device, using a limited capacity unidirectional broadcast channel and without recourse to service-client handshaking. This TPEG application defines: the logical channel, for the transmission of the additional CA information (CAI); how the CAI is link
45、ed and synchronized to the scrambled content. This Technical Specification is related to conditional access applied at the service component level of a TPEG service. It is an open design for the integration of various different conditional access systems, externally specified, which are signalled by
46、 the TPEG service Encryption Indicator to allow client devices to operate correctly. 2 Normative References The following referenced documents are indispensable for the application of this Technical Specification.
