Introduction
Digital Multimedia Broadcasting (DMB) is the first global mobile TV service based on a digital radio
transmission system. DMB provides people with crystal-clear video, theatre-quality audio, and other data
services on the move via in-vehicle terminals or hand-held gadgets like mobile phones so that it makes
possible the information acquisition and consumption anywhere. DMB contents on air include audio-visual
programs, interactive data, web pages, slideshows, TTI (traffic & travel information), etc.
Most users want to store their preferred DMB contents for consuming the contents at their preferred time and
on their preferred device. Many of them also want to share the contents with other people. Contents providers
also want to serve their DMB contents not only through broadcast but also through communication networks.
Thus a standardized format needs to be specified to guarantee the interoperability of the DMB contents
across various devices from different vendors.
DMB AF (Application Format) specification defines a file format that pertains to DMB (more specifically T-DMB
and S-DMB) contents and services. It specifies how to combine the variety of DMB contents with associated
information for a presentation in a well-defined format that facilitates storage, interchange, management,
editing, and presentation of the DMB contents in protected, governed, and interoperable ways.

4 Overview of technology
4.1 Components summary
Figure 1 shows a brief summary of the components of DMB-AF which consists of the MPEG Standards and
non-MPEG Standards. The components of DMB-AF include native DMB contents which can be broadcasted
on air and additional components added by this specification such as file format and metadata.
The native DMB contents include MPEG-4 AVC video, MPEG-1/2/4 audio, interactive video based on MPEG-
4 BIFS, and various kind of data such as MOT slide show, Dynamic Label (DLS), Broadcast web site (BWS),
Traffic and travel information (TTI) based on TPEG, and Java applications (midlet).
For this specification, ISO Base Media File Format and MP4 File Format are used for base file format
structure. MPEG-21 DID is used for organizing and listing content items. TV-Anytime Metadata is used for
contents and user description and is encapsulated by MPEG-21 DID. MPEG-21 REL and IPMP Components
are used for protection and governance of content resources and descriptive metadata. 3GPP Timed Text
Format is used when characters and glyphs rendering in timed manner is required, for example as in karaoke
application.

Figure 3 — Relation to other file formats
4.3 Organization of contents – MPEG-21 DID
MPEG-21 DID (ISO/IEC 21000-2) describes a set of abstract terms and concepts to form a useful model for
defining Digital Items. In the MPEG-21 multimedia framework, the digital item (DI) is a fundamental unit with a
standard representation, identification and metadata for the distribution, and transaction. For the declaration of
the digital item in flexible and general ways, MPEG-21 DID aims to standardize the description for the
definition of the digital item and provides the basic structure for content representation for the DMB content
storage and distribution scenario.
4.4 Content creation and consumption description – TV Anytime Metadata
TV-Anytime (ETSI TS 102 822-1 to 822-9) is a set of specifications for the controlled delivery of multimedia
content to a user's digital video recorder (DVR). It enables applications to exploit local and remote storage in
consumer electronics platforms.
The TV-Anytime metadata are sub-divided into two categories: phase 1 metadata (ETSI TS 102 822-3-1) and
phase 2 metadata (ETSI TS 102 822-3-3). The phase 1 metadata schema has the root element of
TVAMainType and defines mainly about program and user descriptions. The phase 2 metadata schema has
the root element of ExtendedTVAMainType and extends the phase 1 schema for including various content
types and consumption conditions.
For describing creation and consumption information of DMB contents, DMB-AF uses a restricted subset of
the TV-Anytime metadata specification. The restricted subset of TV-Anytime metadata for DMB-AF is defined
in subclause 5.3 of this specification.
DMB-AF also adopts CRID (content referencing Identifier) defined in TV-Anytime Part 4 (ETSI TS 102 822-4)
for identifying a specific content item independent of its location.
© ISO/IEC 2008 – All rights reserved 5

4.5 Protection and governance – MPEG-21 IPMP and REL
4.5.1 Right management and protection
MPEG-21 IPMP (Intellectual Property Management and Protection) Components standard is a DRM (Digital
Right Management) framework developed by MPEG for safe and easy distribution of contents between the
different user terminals and the different content providers. The MPEG-21 IPMP Components standard
provides the means to represent which parts of Digital Items are protected with what IPMP Tools.
For supporting governed and protected usage of DMB contents, DMB-AF adopts a restricted subset of
MPEG-21 IPMP Components. The lists of the functionalities are explained in subclause 5.2 of this
specification. Note that unless specifically mentioned in this specification, the requirements of MPEG-21 DID
and IPMP (ISO/IEC 21000-2 and ISO/IEC 21000-4) apply for digital item declaration and protection in
DMB-AF.
4.5.2 Right expression
ISO/IEC 21000-5 defines a right expression language (REL), which is designed to be domain-agnostic and
comprehensive, and also very flexible and adaptive to the specific scope and requirements of applications
within a particular domain. The language provides extension and profile mechanisms for these purposes.
In DMB-AF, licenses governing the use of content or parts thereof are expressed according to the
dissemination and capture DAC profile of the MPEG-21 REL. The REL DAC profile is designed for usage in
broadcasting applications, which can handle various use cases for DMB-AF applications. Note that the
requirements of the DAC profile of MPEG-21 REL (ISO/IEC 21000-5) apply for right expression in DMB-AF.
4.6 Timed text
3GPP Timed Text format describes the normative behavior of text data for rendering. Timed text supports the
characters and glyphs rendering, font support such as name, size and style, color support of text and
background, text rendering position and composition, etc. By using these functionalities, various applications
such as closed captioning, karaoke, dynamic highlighting and other visual annotation can be deployed in the
user’s terminal.
The synchronized usage of the timed text with other timed media is described in subclause 6.6.
5 Components of DMB-AF
5.1 Supported components and restrictions
In general, DMB Video Service components include audio and visual objects and associated auxiliary data,
which can be carried in MPEG-2 SPTS (Single Program Transport Stream). DMB Audio Service components
include audio stream and associated auxiliary data. DMB Data Service components include various kind of
NPAD (Non Program-Associated-Data).
In Table 1, all the supported components of DMB-AF, except the file format, are listed with the specification
reference of the respective component. Note that DMB-AF does not mandate all the syntax and semantics of
the ‘Specification’ column of Table 1. Instead, it does mandate the component specification with some
restrictions on profiles, levels, and usages, which are defined in the specification of ‘Restriction’ column of the
table. In other words, for each component listed in Table 1, the requirements of the corresponding
specification in the ‘Restriction’ column apply. For example, MPEG-4 AVC in T-DMB service is restricted such
that Baseline Profile Level 1.3 apply with “num_ref_frames = 3” and “pic_order_cnt_type = 2”
according to ETSI TS 102 428. Implementers of this specification shall carefully consult to the specifications in
the ‘Restriction’ column for the exact restrictions made on the supported components.
For the file format components, refer to Section 6 of this specification.

The ipmpinfo:RightsDescriptor element is used for containing rights information that governs the IPMP
information. The ipmpinfo:RightsDescriptor element under the ipmpinfo:Tool element is for each
IPMP Tool. The common rights information about all tools in ipmpinfo:IPMPInfoDescriptor can be
expressed by the ipmpinfo:RightsDescriptor under the ipmpinfo:IPMPInfoDescriptor.
Regarding encryption of resources, AES-128 CTR [32] is used as a default encryption tool in DMB-AF,
meaning that DMB-AF file players compliant to the protection supporting brands of this specification shall be
able to decrypt the resources encrypted by the default encryption tool. In addition, the initiation vector (IV) can
be used as a value of ipmpinfo:initializationSettingsData for AES-128 CTR method.
5.2.4 IPMP General Information Descriptor
IPMP General Information Descriptors in DMB-AF are composed of a subset of MPEG-21 IPMP Information
Descriptor schema in MPEG-21 IPMP Components and MPEG-A Media Streaming Player application
format [17]. The selected elements with restrictions are tabulated as follows.

5.3 Restrictions on TV-Anytime metadata
5.3.1 Introduction
DMB-AF uses a restricted subset of TV-Anytime Metadata for the rich content description and consumption.
The followings are taken into considerations in order to customize the TVA metadata schema for DMB-AF
applications.
- There are many elements that can be used to describe the same information. To reduce usage
ambiguity of such elements, some redundant elements should be eliminated as much as possible.
- There are recursive elements such as ‘item’, which can contain ‘item’s recursively. For a simple
description and devices with limited system resources, the level of recursion should be restricted to a
certain level.
- Those elements which are not essential for DMB-AF applications should be optimized in regards to
the required system resources and possible future usages.
5.3.2 Restricted schema elements
Figure 4 shows a high-level view of the restricted TV-Anytime metadata schema for DMB-AF.
