23、G Public Transport Information application (tpeg-ptiML.ent) 25 CEN ISO/TS 24530-4:2006iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out

24、 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-governmental, in liaison with ISO, also take part in the work. ISO col

25、laborates 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 main task of technical committees is to prepare International S

26、tandards. 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 other circumstances, particularly when there is an urgent ma

27、rket 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 and is accepted for publication if it is approved by more th

28、an 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 members of the committee casting a vote. An ISO/PAS or ISO/TS is

29、 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to deciding whether it should be confirmed for a further three years, revised to become an International Standard, or withdrawn.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 a confirmed ISO/PAS or ISO/TS, it is reviewed again after six years at which time it has to be either transposed int

30、o an International Standard or withdrawn.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 responsible for identifying any or all such patent rights. ISO/TS 24530-4 was prepared by the European Committee for S

31、tandardization (CEN) in collaboration with Technical Committee ISO/TC 204, Intelligent transport systems, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

33、rt 4: tpeg-ptiML CEN ISO/TS 24530-4:2006vIntroduction TPEG in XML (tpegML) provides a solution for diverse requirements for the ultimate delivery of TPEG applications (potentially simultaneously) via for example ARIB, ATSC, DAB, DVB and the Internet. This will solve the minimal adaptation layers req

34、uirement 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 on almost any digital bearer with an appropriate adaptation layer. TPEG messages are delivered fr

35、om 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 brief, from the EBUs Broadcast Management Committee; to develop a new protocol for Traffic and Trave

36、l 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, filtered and understood both by humans (visually and/or audibly) and by agent systems. This brief was al

37、so 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 technically and economically to DAB and possibly to internet bearers, where of the order of up to 10 kbi

38、ts/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 structured (layered) in their ability to handle transparent data services and they include mechanisms

39、 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 Providers who would have a standardised message generation interface, yet be able to develop systems su

40、ited 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 been developed using the DTD approach, which allows the use of different language entity files to

41、 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 browser. This document provides English language entity files only. For other languages the entity f

42、iles 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 Forum Standards Task Force. Attention is drawn to the EBU sponsored TPEG Forum development principl

44、ument establishes the XML encoding of the method of the Public Transport Information application. The Public Transport Information Application is intended to cover all modes of public (ie collective) transport as well as inter-urban and intra-urban travel. The application itself is designed to allow

45、 the efficient and language independent transmission of public transport information either directly to an end-user, be it the public or another service provider, such as broadcasters, service operators or other information disseminating points or centres for onward transmission. TPEG-PTI aims at de

46、scribing “legs” of a journey also described as “rides” by other methodologies. However, it is important to note that TPEG-PTI is not limited to describing single services, because it also allows the more general description of route, service and area wide problems. Public (or collective) transport i

47、nformation is usually consumed in one of four principle ways, and in TPEG-PTI these are labelled views, they are somewhat an analogue to: Leader board information as used at stations or terminals A report on the state of a network The description of an individual service As a news flash report While

48、 the elements needed to produce information for any one of these four “views” are largely germane across the presentations, the end-user focus of TPEG applications is seen as useful to be able to mimic presentations, to which end-users are accustomed. TPEG-PTI views are intended to present informati

49、on to end-users in a way that they are accustomed. TPEG-PTI messages can therefore group data elements to present one of the following views: Incident Report View Station/Terminal View Route View Individual Service View CEN ISO/TS 24530-4:20062 It is important to bear in mind that these “views” are merely presentational aides; they have little to do with the content in the individual data elements. They do, however, indicate how data elements must be grouped if a presentation in any of these
