24、ide federation of national standards bodies (ISO member bodies). The work 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 th
25、at committee. International organizations, governmental and non-governmental, 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
26、accordance with the rules given in the ISO/IEC Directives, Part 2. The main 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 r
27、equires approval by at least 75 % of the member bodies casting a vote. In 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)
28、represents an agreement between technical experts in an ISO working group 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 comm
29、ittee and is accepted for publication if it is approved by 2/3 of the members 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order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn.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 t
30、he ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn.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 s
31、hall not be held responsible for identifying any or all such patent rights. ISO/TS 18234-6 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.

33、t 6: Location referencing applications CEN ISO/TS 18234-6:2006vIntroduction The TPEG technology uses a byte-oriented 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, and are used to
34、 transfer information from the database of a service provider to an end-users equipment. The TPEG-Loc methodology has been developed to provide a unified location referencing system for all TPEG applications that require such referencing systems. This CEN ISO Technical Specification describes the TP
35、EG-Loc application in detail. TPEG-Loc is designed to offer service providers and end-users several large and significant advantages over previous location based services. TPEG-Loc forms the basis of location referencing for any TPEG application that may be specified. It is very important to remembe
36、r the original TPEG objectives, which ensure that the TPEG-Loc is designed to meet all needs. It is flexible in use, from both a service provision and end-user viewpoint. TPEG-Loc offers choices for service providers to provide simple single-application services through to multi-application services
37、 using the same location referencing method. TPEG-Loc offers filtering choices for end-users to provide wide or narrowly focussed information, both urban and inter-urban and for single or multi-modal journeys. TPEG-Loc provides for both large networked service providers and small single area service
38、 providers and allows a full range of end-user products to be developed, from thick clients such as navigation systems to thin clients such as small hand held travel assistants. The Broadcast Management Committee of the European Broadcast Union (EBU) established the B/TPEG project group in autumn 19
39、97 with the mandate to develop, as soon as possible, a new protocol for broadcasting traffic and travel-related information in the multimedia environment. The TPEG technology, its applications and service features are designed to enable travel-related messages to be coded, decoded, filtered and unde
40、rstood by humans (visually and/or audibly in the users language) and by agent systems. One year later in December 1998, the B/TPEG group produced its first public specifications. Two documents were released. Part 2 (TPEG-SSF, CEN ISO/TS 18234-2) described the Syntax, Semantics and Framing structure,
41、 which will be used for all TPEG applications. Part 4 (TPEG-RTM, CEN ISO/TS 18234-4) described the first application, for Road Traffic Messages. CEN /C 278/WG 4, in conjunction with ISO/TC 204/WG 10, established a project group comprising the members of B/TPEG and they have continued the work concur
42、rently since March 1999. Since then two further parts have been developed to make the initial complete set of four parts, enabling the implementation of a consistent service. Part 3 (TPEG-SNI, CEN ISO/TS 18234-3) describes the Service and Network Information Application, which is likely to be used b
43、y all service implementations to ensure appropriate referencing from one service source to another. Part 1 (TPEG-INV, CEN ISO/TS 18234-1), completes the work, by describing the other parts and their relationship; it also contains the application IDs used within the other parts. In April 2000, the B/
44、TPEG group released revised Parts 1 to 4, all four parts having been reviewed and updated in the light of initial implementation results. Thus a consistent suite of specifications, ready for wide scale implementation, was submitted to the CEN/ISO commenting process. In November 2001, after extensive
45、 response to the comments received and from many internally suggested improvements, all four parts were completed for the next stage: the Parallel Formal Vote in CEN and ISO. But a major step forward has been to develop the so-called TPEG-Loc location referencing method, which enables both map-based
46、 TPEG-decoders and non map-based ones to deliver either map-based location referencing or human readable information. Part 6 (TPEG-Loc, CEN ISO/TS 18234-6, this document) is now a separate specification and is used in association with the other parts of CEN ISO/TS 18234 to provide comprehensive loca
47、tion referencing. Additionally Part 5, the Public Transport Information Application (TPEG-PTI, CEN ISO/TS 18234-5), has been developed and been through the commenting process. CEN ISO/TS 18234-6:2006vi This Technical Specification, CEN ISO/TS 18234-6, describes the data structure, the encoding and d
48、ecoding of “TPEG-Loc”. This document has been prepared by CEN/TC 278 Road Transport and Traffic Telematics in co-operation with ISO/TC 204, Intelligent Transport Systems. During the development of the TPEG technology a number of versions have been documented and various trials implemented using vari
49、ous versions of the specifications. At the time of the publication of this Technical Specification, all parts are fully inter-workable and no specific dependencies exist. This Technical Specification has the technical version number TPEG-Loc_3.0/001.
