23、ef 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 were designed to enable travel-related messages to be coded, decoded, filtered and understood by humans (vi
24、sually 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 adaptation layer, was developed. Hierarchically structured TPEG messages from service providers to end-users were de
25、signed 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 documents were released. Part 2 (TPEG-SSF, which became ISO/TS 18234-2) described the Syntax, Semantics and Framing
26、 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 March 1999, CEN TC 278/WG 4, in conjunction with ISO/TC 204/WG 10, established a project group comprising members
27、of the former EBU B/TPEG and they continued the work concurrently. 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
28、 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 also contained the application IDs used within the other parts. Additionally, Part 5, the Public Tra
29、nsport 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 deliver either map-based location referencing or human readable text information, was issued as ISO/TS 18
30、234-6 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 Generation 2With the inauguration of the Traveller Information Services Association (TISA) in December 2007
31、derived from former Forums and the CEN/ISO development project group, the TPEG Applications Working Group took over development work for TPEG technology.It was about this time that the (then) new Unified Modeling Language (UML) was seen as having major advantages for the development of new TPEG Appl
32、ications in communities who would not necessarily have binary physical format skills required to extend the original TPEG TS work. It was also realised that the XML format for TPEG described within the ISO/TS 24530-series (now superseded) had a greater significance than previously foreseen; especial
33、ly 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 be UML based this has subsequently become known as TPEG Generation 2.TPEG2
34、 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 strategy covered in Parts 2, 3, 4 and the conversion to two current physical
35、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 minimise drafting errors, that forms the Annex for each physical format.vi ISO 2014 All rights reservedPD ISO/TS 21219-2:
36、2014ISO/TS 21219-2:2014(E)TPEG2 has a three container conceptual structure: 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 w
37、ider for hierarchical message content.Toolkit parts: TPEG2-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), TPE

39、hich may be delivered by vectoring data included in the Location Referencing Container.TPEG2 has been developed to be broadly (but not totally) backward compatible with TPEG1 to assist in transitions from earlier implementations, whilst not hindering the TPEG2 innovative approach and being able to s
40、upport many new features, such as dealing with applications having both long-term, unchanging content and highly dynamic content, such as Parking Information.
