Digital Audio Broadcasting (DAB); Multimedia Object Transfer (MOT) protocol

Scope

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 ETS 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 1866 [3]) or Multimedia and Hypermedia information coding Experts Group (MHEG) (see ISO/IEC CD 13522 [4]).
