A list of all parts in the ISO 21219 series can be found on the ISO website.iv ISO 2017 All rights reserved ISO/TS 21219-7:2017(E) Introduction History TPEG technology was originally proposed by the European Broadcasting Union (EBU)

15、 Broadcast Management Committee, who established the B/TPEG project group in the autumn of 1997 with a brief 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 w

16、ere designed to enable travel-related messages to be coded, decoded, filtered and understood by humans (visually and/or audibly in the users language) and by agent systems. Originally, a byte-oriented data stream format, which may be carried on almost any digital bearer with an appropriate adaptatio

17、n layer, was developed. Hierarchically structured TPEG messages from service providers to end-users were designed to transfer information from the service provider database to an end-users equipment. One year later, in December 1998, the B/TPEG group produced its first EBU specifications. Two docume

18、nts were released. Part 2 (TPEG-SSF, which became ISO/TS 18234-2) described the syntax, semantics and framing structure, which was used for all TPEG applications. Meanwhile, Part 4 (TPEG- RTM, which became ISO/TS 18234-4) described the first application for road traffic messages. Subsequently, in Ma

19、rch 1999, CEN/TC 278, in conjunction with ISO/TC 204, established a group comprising members of the former EBU B/TPEG and this working group continued development work. Further parts were developed to make the initial set of four parts, enabling the implementation of a consistent service. Part 3 (TP

20、EG-SNI, ISO/TS 18234-3) described the service and network information application used by all service implementations to ensure appropriate referencing from one service source to another. Part 1 (TPEG-INV, ISO/TS 18234-1) completed the series by describing the other parts and their relationship; it

21、also contained the application IDs used within the other parts. Additionally, Part 5, the public transport information application (TPEG-PTI, ISO/TS 18234-5), was developed. The so-called TPEG-LOC location referencing method, which enabled both map-based TPEG-decoders and non-map- based ones to deli

22、ver either map-based location referencing or human readable text information, was issued as ISO/TS 18234-6 to be used in association with the other applications parts of the ISO/TS 18234 series to provide location referencing. The ISO/TS 18234 series has become known as TPEG Generation 1. TPEG Gener

23、ation 2 When the Traveller Information Services Association (TISA), derived from former forums, was inaugurated in December 2007, TPEG development was taken over by TISA and continued in the TPEG applications working group. It was about this time that the (then) new Unified Modelling Language (UML)

24、was seen as having major advantages for the development of new TPEG applications in communities who would not necessarily have binary physical format skills required to extend the original TPEG TS work. It was also realized that the XML format for TPEG described within the ISO/TS 24530 series (now s

25、uperseded) had a greater significance than previously foreseen, especially in the content-generation segment, and that keeping two physical formats in synchronism, in different standards series, would be rather difficult. As a result, TISA set about the development of a new TPEG structure that would

26、 be UML based. This has subsequently become known as TPEG Generation 2. TPEG2 is embodied in the ISO/TS 21219 series and it comprises many parts that cover introduction, rules, toolkit and application components. TPEG2 is built around UML modelling and has a core of rules that contain the modelling

27、strategy covered in ISO/TS 21219-2, ISO/TS 21219-3 and ISO/TS 21219- 4 and the conversion to two current physical formats: binary and XML; others could be added in the future. TISA uses an automated tool to convert from the agreed UML model XMI file directly into an MS Word document file, to minimiz

28、e drafting errors, that forms the annex for each physical format. ISO 2017 All rights reserved v ISO/TS 21219-7:2017(E) TPEG2 has a three container conceptual structure: message management (ISO/TS 21219-6), application (several parts) and location referencing (ISO/TS 21219-7). This structure has fle

29、xible capability and can accommodate many differing use cases that have been proposed within the TTI sector and wider for hierarchical message content. TPEG2 also has many location referencing options as required by the service provider community, any of which may be delivered by vectoring data incl

30、uded in the location referencing container. The following classification provides a helpful grouping of the different TPEG2 parts according to their intended purpose. Toolkit parts: TPEG2-INV (ISO/TS 21219-1), TPEG2-UML (ISO/TS 21219-2), TPEG2-UBCR (ISO/TS 21219-3), TPEG2-UXCR (ISO/TS 21219-4), TPEG

31、2-SFW (ISO/TS 21219-5), TPEG2-MMC (ISO/TS 21219-6), TPEG2-LRC (ISO/TS 21219-7) and TPEG2-LTE (ISO/TS 21219-24). Special applications: TPEG2-SNI (ISO/TS 21219-9) and TPEG2-CAI (ISO/TS 21219-10). Location referencing: TPEG2-ULR (ISO/TS 21219-11 1) ), TPEG2-GLR (ISO/TS 21219-21 1) ) and TPEG2- OLR (ISO

32、/TS 21219-22). Applications: TPEG2-PKI (ISO/TS 21219-14), TPEG2-TEC (ISO/TS 21219-15), TPEG2-FPI (ISO/TS 21219-16), TPEG2-TFP (ISO/TS 21219-18), TPEG2-WEA (ISO/TS 21219-19), TPEG2-RMR (ISO/TS 21219-23) and TPEG2-EMI (ISO/TS 21219-25). TPEG2 has been developed to be broadly (but not totally) backward

33、 compatible with TPEG1 to assist in transitions from earlier implementations, while not hindering the TPEG2 innovative approach and being able to support many new features, such as dealing with applications having both long-term, unchanging content and highly dynamic content, such as parking informa

35、 experts group, generation 2 (TPEG2) Part 7: Location referencing container (TPEG2-LRC) 1 Scope This document establishes the method of signalling the specific location referencing used by all TPEG2 applications that require detailed location information to be delivered to client devices such as TPE

36、G2- TEC. The TPEG2-location referencing container (TPEG2-LRC) is described and shows how it is used to signal which specific location referencing method is in use for a particular TPEG message. It is able to handle location referencing methods that are external to the present ISO series and the inte

ISO 2017 All rights reserved 1 ISO/TS 21219-7:2017(E) Digital map based systems, either on the message generation (server) side or on the client (end-user) side, tend to be based upon road mapping rather than, for example, rail track mapping. Therefore, throughout this specification s

44、eries, there is a tendency to use roads as examples. However, roads are not necessarily implied, so the use and context of an element shall be clarified. 3.1 TPEG client end users device, usually consisting of a bearer level tuner/receiver, a TPEG decoder and a human machine interface 3.2 dynamic lo

47、gether in one place Note 1 to entry: Many TPEG applications are designed to deliver TPEG messages, which consist of three high-level containers, each with one or more elements. These containers are for: message management, event information and location referencing information. Note that some specia

48、l application messages do NOT include a location referencing container, such as a cancellation message. It should also be noted that each container does not necessarily have all possible lower level elements included. Figure 1 shows the “container view” structure used, for example, when a TPEG2-TEC

49、(ISO/TS 21219-15) application message is generated to describe a road event and location references need to be given to the end-user. The main purpose of the location referencing container is to provide both human understandable and machine- readable elements to appropriate client decoders. It may be delivered to a “thin client”, which, for example, is only able to convey limited location referencing information to the end-user or it may be delivered to a “thick client” using a considerable number of ele
