The present document specifies a transmission protocol, which allows to broadcast various kinds of data using the
Digital Audio Broadcasting (DAB) system. It is tailored to the needs of Multimedia services and the specific constraints
given by the broadcasting characteristics of the DAB system. After reception this data can be processed and presented
to the user.
The present document defines the transport specific encoding for data types not specified in EN 300 401 [1] according
to the transport mechanisms provided by DAB. It allows a flexible utilization of the data channels incorporated in the
DAB system, as well as methods to manage and maintain a reliable transmission in a uni-directional broadcast
environment. Provisions are also made for the creation and presentation of advanced Multimedia services using formats
such as Hyper Text Markup Language (HTML) (see RFC 2854 [2]) or Multimedia and Hypermedia information coding
Experts Group (MHEG) (see ISO/IEC 13522 [3]).
The present document describes the core transport protocol. Subsequent parts or revisions of the present document will
describe backwards compatible extensions.
Aspects related to the further decoding and processing of the data objects carried are outside the scope of the present
document. Hardware implementation considerations are not covered.
