Intelligent transport systems - Traffic and travel information (TTI) via transport protocol experts group, generation 1 (TPEG1) binary data format - Part 10: Conditional access information (TPEG1-CAI) (ISO/TS 18234-10:2013)

This Technical Specification contains the definition of the TPEG Conditional Access Information (CAI) application. It enables dedicated conditional access data, such as management messages (e.g. Control Words and Entitlement Control Messages) to be delivered to recipient client devices. This TPEG application is designed for a service provider to: establish setup, prolongation or revocation of services to a specific client device, using a limited capacity unidirectional broadcast channel and without recourse to service-client handshaking. This TPEG application defines: - the logical channel, for the transmission of the additional CA information (CAI); - how the CAI is linked and synchronized to the scrambled content. This Technical Specification is related to conditional access applied at the service component level of a TPEG service. It is an open design for the integration of various different conditional access systems, externally specified, which are signalled by the TPEG service Encryption Indicator to allow client devices to operate correctly.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
 an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
 an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 18234-10 was prepared by the European Committee for Standardization (CEN) Technical Committee

Introduction
TPEG technology uses a byte-oriented data stream format, which may be carried on almost any digital bearer
with an appropriate adaptation layer. TPEG-messages are delivered from service providers to end-users and
used to transfer information from the database of a service provider to an end-user’s equipment.
The brief history of TPEG technology development dates back to the European Broadcasting Union (EBU)
Broadcast Management Committee establishing the B/TPEG project group in autumn 1997 with the mandate
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 are 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.
One year later in December 1998, the B/TPEG group produced its first EBU specifications. Two Technical
Specifications were released. ISO/TS 18234-2, described the Syntax, Semantics and Framing Structure,
which is used for all TPEG applications. ISO/TS 18234-4 (TPEG-RTM) described the first application, for
Road Traffic Messages.
Subsequently, CEN/TC 278/WG 4, in conjunction with ISO/TC 204, established a project group comprising the
members of B/TPEG and they have continued the work concurrently since March 1999. Since then two further
parts were developed to make the initial complete set of four parts, enabling the implementation of a
consistent service. ISO/TS 18234-3 (TPEG-SNI) describes the Service and Network Information Application,
which should be used by all service implementations to ensure appropriate referencing from one service
source to another. ISO/TS 18234-1 (TPEG-INV), completes the series, by describing the other parts and their
relationship; it also contains the application IDs used within the other parts. Additionally ISO/TS 18234-5 the
Public Transport Information Application (TPEG-PTI) and ISO/TS 18234-6 (TPEG-LRC), were developed.
TPEG applications are developed using UML modelling and a software tool is used to automatically select
content which then populates this TS. Diagrammatic extracts from the model are used to show the capability
of the binary coding in place of lengthy text descriptions; the diagrams do not necessarily include all relevant
content possible.
This Technical Specification describes the binary data format of the on-air interface of the Conditional Access
Information application, (TPEG-CAI) with the technical version number TPEG-CAI_1.0/001.
CAI application
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.

binary data format —
Part 10:
Conditional access information (TPEG-CAI)
1 Scope
This Technical Specification contains the definition of the TPEG Conditional Access Information (CAI)
application. It enables dedicated conditional access data, such as management messages (e.g. Control
Words and Entitlement Control Messages) to be delivered to recipient client devices. This TPEG application is
designed for a service provider to: establish setup, prolongation or revocation of services to a specific client
device, using a limited capacity unidirectional broadcast channel and without recourse to service-client
handshaking.
This TPEG application defines:
 the logical channel, for the transmission of the additional CA information (CAI);
 how the CAI is linked and synchronized to the scrambled content.
This Technical Specification is related to conditional access applied at the service component level of a TPEG
service. It is an open design for the integration of various different conditional access systems, externally
specified, which are signalled by the TPEG service Encryption Indicator to allow client devices to operate
correctly.

4 Application identification and version number signalling
4.1 Application identification
The word 'application' is used in the TPEG specifications to describe specific subsets of the TPEG structure.
An application defines a limited vocabulary for a certain type of messages, for example parking information or
road traffic information. Each TPEG application is assigned a unique number, called the Application
Identification (AID). An AID is defined whenever a new application is developed and these are all listed in
ISO/TS 18234-1.
The application identification number is used within the TPEG-SNI application to indicate how to process
TPEG content and facilitates the routing of information to the appropriate application decoder.
4.2 Version number signalling
Version numbering is used to track the separate versions of an application through its development and
deployment. The differences between these versions may have an impact on client devices.
The version numbering principle is defined in ISO/TS 18234-1.
Table 1 shows the current version numbers for signalling CAI within the SNI application:

5 Service Component Data
TPEG-CAI makes use of the "Service component data with dataCRC" according to Annex A, section
A.3.2.6.2.1. For explanatory purposes, this is repeated here.
< ServCompFrameProtected >:= : CRC protected service component frame
(header), : Component frame header as defined in A.3.2.6.1
external (content), : Content specified by the individual application
(dataCRC); : CRC starting with first byte after the header

The main frame of CAI defines ApplicationContent as follows:

:= : application content
messageCount * (msg);
: Any number of any CAI message components

6 Conditional Access Methodology
Conditional access (CA) is specified within TPEG-SSF and TPEG-SNI as a function being applied on service
frame or service component level. The method used is indicated via the Encryption Identifier (EncID) directly
in the service frame or for components via the SNI Fast Tuning Table (Guide to the Services 1). This
specification is related to conditional access applied on service component level.
Generally, a broadcast based CA-system requires encryption related data to be transmitted which is
independent from the content, but necessary for decryption and subscriber management.
If a conditional access system is applied on the TPEG service component level, some service components
may be encrypted using the same "encryption key", while others remain unencrypted or use different
"encryption keys". Therefore, several service components can share the same conditional access information
, if they are supposed to be offered as one bundle and hence are encrypted with the same keys.
Each of the aforementioned bundles may require CA-management-messages, which have to be transmitted
separated from the (encrypted) content in the corresponding service components. The most appropriate way
for the transport is the use of separate service components of a dedicated application type.
For each encrypted TPEG-Service component a link or reference to the service component carrying the
relevant CA information is required. This is handled by TPEG-SNI GST-Table 6, Conditional Access
Information Reference.
EXAMPLE
A TPEG Service may contain the following service components:
SCID Application
0 SNI
2 TEC
5 TEC (encrypted)
7 TEC (encrypted)
8 PTI
10 PKI (encrypted)
20 CAI
21 CAI
30 CAI

---------------------- Page: 15 ----------------------

SIST-TS CEN ISO/TS 18234-10:2014
ISO/TS 18234-10:2013(E)
The service components 5 and 7 are encrypted with key 1, while service component 10 is encrypted using key
2. Hence two components with CA-meta information for the corresponding component are required, in the
example listed as SCID 20 and 21. A third CAI component, in the example number 30, contains CA-meta
information that relates to all encrypted components independent which key is applied.
This specification describes the generic containers for the CAI application. The container content will be
proprietary and specified individually for each CA-System indicated by the encryption indicator (EncID). The
linking between encrypted service components and related CAI-Components is achieved via a reference table
within the TPEG-SNI application.
7 Message Components
Unlike other TPEG applications, TPEG-CAI does not use a Message Management Container and does not
use a Location Referencing Container; it only uses an Application Event Container.

A TPEG-CAI Message includes solely one single container for proprietary CA data.
The CAI Message Container is available to carry data, which is defined within the CA system specific
specifications. The CAIDataUnit is directly following after the lengthAttr of the CAIMessage.

Annex A
(normative)

Binary SSF and Data Types
A.1 Conventions and symbols
A.1.1 Conventions
A.1.1.1 Byte ordering
All numeric values using more than one byte are coded in “Big Endian” format (most significant byte first).
Where a byte is subdivided into bits, the most significant bit (“b7”) is at the left-hand end and the least
significant bit (“b0”) is at the right-hand end of the structure.
A.1.1.2 Method of describing the byte-oriented protocol
TPEG uses a data-type representation for the many structures that are integrated to form the transmission
protocol. This textual representation is designed to be unambiguous, easy to understand and to modify, and
does not require a detailed knowledge of programming languages.
Data types are built up progressively. Primitive elements, which may be expressed as a series of bytes are
built into compound elements. More and more complex structures are built up with compound elements and
primitives. Some primitives, compounds and structures are specified in this Technical Specification, and apply
to all TPEG Applications. Other primitives, compounds and structures are defined within applications and are
local only to that application.
A resultant byte-stream coded using C-type notation is shown in ISO/TS 18234-2:2006, Annex E.
A.1.1.3 Reserved data fields
