22、 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 that committee. Int
23、ernational 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 accordance with t
24、he 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 requires approval
25、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) represents an agr
26、eement 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 committee and is acce
27、pted 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 with a view to deciding whether it should be confirmed for a further three years, revised to become an International Standard, or withdrawn. In the case of
28、 a confirmed ISO/PAS or ISO/TS, it is reviewed again after six years at which time it has to be either transposed into an International Standard or withdrawn.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 r
29、esponsible for identifying any or all such patent rights. ISO/TS 24530-2 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 204, Intelligent transport systems, in accordance with the Agreement on technical cooperation between ISO and CEN
30、 (Vienna Agreement). Throughout the text of this document, read “.this European pre-Standard.” to mean “.this Technical Specification.”. ISO/TS 24530 consists of the following parts, under the general title Traffic and Travel Information (TTI) TTI via Transport Protocol Experts Group (TPEG) Extensib
31、le Markup Language (XML): Part 1: Introduction, common data types and tpegML Part 2: tpeg-locML Part 3: tpeg-rtmML Part 4: tpeg-ptiML v Introduction TPEG in XML (tpegML) provides the solution to diverse requirements for the ultimate delivery of TPEG applications (potentially simultaneously) via for
32、example ARIB, ATSC, DAB, DVB and the Internet. This will solve the minimal adaptation layers requirement and without doubling up on message carousels, which are handled at different layers of the protocol stacks. The original TPEG technology uses a byte-oriented stream format, which may be carried o
33、n almost any digital bearer with an appropriate adaptation layer. TPEG messages are delivered from service providers to end- users, and are used to transfer application data from the database of a service provider to an end-users equipment. TPEG binary was initially designed to meet a particular bri
34、ef, from the EBUs Broadcast Management Committee; to develop a new protocol for Traffic and Travel Information, for use in the multimedia broadcasting environment. TPEG applications were developed with service and transport features, which enable travel-related messages to be coded, decoded, filtere
35、d and understood both by humans (visually and/or audibly) and by agent systems. This brief was also endorsed by the EBU TTI Broadcast Strategy Team, who recognized the vital importance of a bearer independent TTI protocol. The development of TPEG binary technology is excellently matched both technic
36、ally and economically to DAB and possibly to internet bearers, where of the order of up to 10 kbits/s is considered acceptable. However other bearers such as ARIB, ATSC and DVB may be able to offer much higher data rates with economic and technical utility. Nevertheless these bearers are highly stru
37、ctured (layered) in their ability to handle transparent data services and they include mechanisms suitable for carousel delivery, which would require a considerably different TPEG data structure before real transparency could be achieved. Another potential use of tpegML is provided to Service Provid
38、ers who would have a standardised message generation interface, yet be able to develop systems suited to their own requirements. This will enable Service Providers to exchange pre-edited information regardless of their message generation systems and be substantially language independent. tpegML has
39、been developed using the DTD approach, which allows the use of different language entity files to easily provide a truly language independent service. This approach has the advantage that tpegML files can be rendered in any language, provided the language entity file is available to the internet bro
40、wser. This document provides English language entity files only. For other languages the entity files in this document only require direct translation. The development of this ISO/TS 24530 series was undertaken jointly with European Broadcasting Union B/TPEG Group, which has evolved into the TPEG Fo
41、rum Standards Task Force. Attention is drawn to the EBU sponsored TPEG Forum development principles, which require all inputs containing IPR to be declared during drafting work. No such declarations have been made. CEN ISO/TS 24530-2:2006blank1 Traffic and Travel Information (TTI) TTI via Transport
42、Protocol Experts Group (TPEG) Extensible Markup Language (XML) Part 2: tpeg-locML 1 Scope This document establishes the XML encoding of the method of Location Referencing used by TPEG applications. TPEG applications contain the information required by a client TPEG decoder (i.e. both Location Refere
43、ncing and event information), to present all the information intended for the end-user when it was originated by the service provider. Location Referencing requires a service provider to give an impression or image, to the human end-user, of where an event has taken place. This cannot be done easily
44、 because the human end-user may or may not be familiar with the location. tpeg-loc has the added challenge of attempting to be as language independent as possible. This is achieved by the use of tpeg-loc tables (essentially word-oriented data object dictionaries). tpeg-loc is the recommended Locatio
45、n Referencing system for TPEG. It provides location data in a machine readable form that allows a “thick” client such as a navigation system to map-match, on-the-fly, to locate the event being described onto a digital map display. However, it is possible to additionally use other location methods, s
46、uch as the Link-id method by suitably modifying the tpegML.dtd to include the relevant lines, e.g.: %link-idML; It is vital, for further understanding of this document, to have more than a passing understanding of the tpeg-loc binary specification which describes, among other things, in a step-by st
47、ep approach: point, link and area definitions, and how they are structured to provide a full Location Referencing system. 2 Normative references The following referenced documents are indispensable for the application of this document.
