19、rved v ISO/TS 21219-5:2015(E) Introduction History TPEG technology was originally proposed by the European Broadcasting Union (EBU) 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 broadcas
20、ting traffic and travel-related information in the multimedia environment. TPEG technology, its applications and service features were 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 syste
21、ms. Originally a byte-oriented data stream format, which may be carried on almost any digital bearer with an appropriate adaptation layer, was developed. Hierarchically structured TPEG messages from service providers to end-users were designed to transfer information from the service provider databa
22、se to an end-users equipment. One year later in December 1998, the B/TPEG group produced its first EBU specifications. Two documents 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. Meanwhil
23、e Part 4 (TPEG-RTM, which became ISO/TS 18234-4) described the first application, for Road Traffic Messages. Subsequently in March 1999, CEN TC 278/WG 4, in conjunction with ISO/TC 204/WG 10, established a project group comprising members of the former EBU B/TPEG and they continued the work concurre
24、ntly. Further parts were developed to make the initial set of four parts, enabling the implementation of a consistent service. Part 3 (TPEG-SNI, ISO/TS 18234-3) described the Service and Network Information Application, used by all service implementations to ensure appropriate referencing from one s
25、ervice source to another. Part 1 (TPEG-INV, ISO/TS 18234-1), completed the series, by describing the other parts and their relationship; it also contained the application IDs used within the other parts. Additionally, Part 5, the Public Transport Information Application (TPEG-PTI, ISO/TS 18234-5), w
26、as developed. The so- called TPEG-LOC location referencing method, which enabled both map-based TPEG-decoders and non map-based ones to deliver 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
27、 parts of the ISO/TS 18234-series to provide location referencing. The ISO/TS 18234-series has become known as TPEG Generation 1. TPEG Generation 2 With the inauguration of the Traveller Information Services Association (TISA) in December 2007 derived from former Forums and the CEN/ISO development p
28、roject group, the TPEG Applications Working Group took over development work for TPEG technology. It was about this time that the (then) new Unified Modelling Language (UML) was seen as having major advantages for the development of new TPEG Applications in communities who would not necessarily have
29、 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 superseded) had a greater significance than previously foreseen; especially in the content-generation segment and that keeping
30、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 be UML based this has subsequently become known as TPEG Generation 2. TPEG2 is embodied in the ISO/TS 21219-series and it compr
31、ises 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 strategy covered in Parts 2, 3, 4 and the conversion to two current physical formats: binary and XML; others could be added in th
32、e future. TISA uses an automated tool to convert from the agreed UML model XMI file directly into an MS Word document file, to minimize drafting errors, that forms the Annex for each physical format.vi ISO 2015 All rights reserved ISO/TS 21219-5:2015(E) TPEG2 has a three container conceptual structu
33、re: Message Management (Part 6), Application (many Parts) and Location Referencing (Part 7). This structure has flexible 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 refe
34、rencing options as required by the service provider community, any of which may be delivered by vectoring data included in the Location Referencing Container. The following classification provides a helpful grouping of the different TPEG2 parts according to their intended purpose: Toolkit parts: TPE
35、G2-INV (Part 1), TPEG2-UML (Part 2), TPEG2-UBCR (Part 3), TPEG2-UXCR (Part 4), TPEG2-SFW (Part 5), TPEG2-MMC (Part 6), TPEG2-LRC (Part 7) Special applications: TPEG2-SNI (Part 9), TPEG2-CAI (Part 10) Location referencing: TPEG2-ULR (Part 11), TPEG2-ETL (Part 20), TPEG2-GLR (Part 21), TPEG2-OLR (Part

37、dering 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 Information.

ISO 2015 All rights reserved vii Intelligent transport systems - Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) Part 5: Service framework (TPEG2-SFW) 1 Scope This series of Technical Specifications establishes a metho
39、d of conveying data for a wide range of applications that require the efficient transmission of point to multi-point data over potentially unreliable broadcast channels. It is also suitable for point-to-point and multicast applications and may easily be encapsulated in Internet Protocol. This Techni
40、cal Specification describes the basic capabilities of the generation 2 TPEG (TPEG2) for providing a multiplex of TPEG Services and applications. Together with the definitions of the general TPEG UML modelling rules and the particular physical TPEG representations for TPEG- binary streams (TISA: TPEG
