22、ommittee, 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 were designed to enable

23、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 adaptation layer, was developed.

24、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 documents were released. Part 2

25、 (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 March 1999, CEN TC 278/WG 4,

26、 in conjunction with ISO/TC 204/WG 10, 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 (TPEG-SNI, ISO/TS

27、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 also contain

28、ed 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 deliver either m

29、ap-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 Generation 2 When

30、 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) was seen as

31、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 superseded) h

32、ad 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 be UML based

33、, 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 strategy cove

34、red in ISO/TS 21219-2, ISO/TS 21219-3, 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 minimize drafting errors

35、, that forms the Annex for each physical format.vi ISO 2016 All rights reservedPD ISO/TS 21219-10:2016ISO/TS 21219-10:2016(E) TPEG2 has a three container conceptual structure: Message Management (ISO/TS 21219-6), Application (many Parts) and Location Referencing (ISO/TS 21219-7). This structure has

36、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 referencing options as required by the service provider community, any of which may be delivered by vectoring data i

37、ncluded 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), T

38、PEG2-SFW (ISO/TS 21219-5), TPEG2-MMC (ISO/TS 21219-6), TPEG2-LRC (ISO/TS 21219-7); Special applications: TPEG2-SNI (ISO/TS 21219-9), TPEG2-CAI (ISO/TS 21219-10); Location referencing: TPEG2-ULR (ISO/TS 21219-11), TPEG2-GLR (ISO/TS 21219-21), TPEG2-OLR (ISO/TS 21219-22); Applications: TPEG2-PKI (ISO/

39、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). TPEG2 has been developed to be broadly (but not totally) backward compatible with TPEG1 to assist in transitions from earlier implementation

40、s, 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 Information.

42、2-CAI) 1 Scope This part of ISO/TS 21219 defines the TPEG Conditional Access Information (CAI) application. It allows to protect the content of a TPEG service from unauthorized access. It further supports the management of subscriber information (e.g. Control Words and ECM) on the client devices in

43、order to setup, prolong or revoke a subscription on a given client device. The application defines the logical channel, for the transmission of the additional CA information (CAI), and how the CAI is linked and synchronized to the scrambled content. This part of ISO/TS 21219 is related to conditiona

44、l access applied on service component level. It is open for an integration of different conditional access systems. NOTE The basic concept behind the CAI application is to transport CAI in separate TPEG service components of a dedicated application type and to define an SNI table that contains the l

45、ink between scrambled content and related CAI. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 service collection of different information streams (applications) logically bound together and delivered from a service provider to the end user 2

46、.2 service component information stream (application) that is part of a service (2.1) Note 1 to entry: A TPEG stream is logically divided into parts known as service components. Each service component carries an application instance. A service component is effectively a “channel” within the multiple

47、x of a TPEG stream. Each stream comprises a number of these “channels” which are identified by the component identifier in TPEG2-SFW 5 and linked to the COID and AID in the TPEG2-SNI application. 3 Abbreviated terms For the purposes of this Technical Specification, the following abbreviated terms ap
