ISO/TS 21219-10:2016

Intelligent transport systems — Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) — Part 10: Conditional access information (TPEG2-CAI)

ISO/TS 21219-10:2016 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 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. ISO/TS 21219-10:2016 is related to conditional 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 link between scrambled content and related CAI.

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 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 (visually
and/or audibly in the user’s 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
designed to transfer information from the service provider database to an end-user’s 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. 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
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 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 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 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 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 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 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) 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 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 strategy covered 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, that forms the Annex for each physical format.

ISO/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 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 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: TPEG2-INV (ISO/TS 21219-1), TPEG2-UML (ISO/TS 21219-2), TPEG2-UBCR
(ISO/TS 21219-3), TPEG2-UXCR (ISO/TS 21219-4), TPEG2-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
