Foreword This Technical Specification (TS) has been produced by the Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the E

16、uropean Telecommunications Standards Institute (ETSI). NOTE 1: The EBUETSI JTC Broadcast was established in 1990 to Co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of

17、Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the Co-ordination of its members activities in the technical, legal, programme-making and programme-exch

18、ange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva. European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 The Eureka Project 147 was established in 1987, with fu

19、nding from the European Commission, to develop a system for the broadcasting of audio and data to fixed, portable or mobile receivers. Their work resulted in the publication of European Standard, ETS 300 401 2, for DAB (see note) which now has worldwide acceptance. The members of the Eureka Project

20、147 are drawn from broadcasting organizations and telecommunication providers together with companies from the professional and consumer electronics industry.

21、resent document covers the core Digital Audio Broadcasting (DAB) requirements to enable interactive services supporting broadcasting to mobile, portable and fixed receivers with narrowband return channels. The system defined in the present document provides a variety of generic solutions for a varie

22、ty of future interactive services, through the adoption of the MOT protocol (specific for DAB) and the IP protocol. The interactive services are provided on systems consisting of a high bitrate downstream channel (up to the maximum bitrate of the broadcast channel) from the service providers to serv

23、ice consumers and low bitrate interaction channels. The Broadcast service provider and the interactive service provider need not operate from the same location (see figure 2). The services are seen from DAB Program Associated Data (PAD) enhanced and standalone (packet mode) data broadcasting service

24、s with interactivity. At the simplest level the interactive channel allows the consumer to react by voting, to order articles displayed in the broadcast or make reservations of hotel rooms, restaurant tables, etc. It is also possible to deliver text, graphics, audio and still pictures (including e-m

25、ail) on-demand, both via the broadcast channel and the interaction channel. There are many possible network configurations covering the currently specified DAB broadcast options including terrestrial, satellite and cable in conjunction with GSM, PSTN, ISDN, DECT and other interactive channel options

26、. The specification of the network dependent protocols are specified within TS 101 737 3. In the process of producing the present document the specifications for an interaction channel for Digital Video Broadcasting (DVB) has carefully been studied. The goal has been to as far as possible be compati

27、ble with the DVB solutions thereby creating a common concept of treating the combination broadcast-/telecommunicationsystem. Although the use of existing DAB data transfer protocols for the broadcast channel, when appropriate, has been essential in the writing of the present document. 2 References T

42、here all the physical (electrical) transmission parameters are defined. The present document addresses the lower two layers (the physical and transport) leaving the application layer open to competitive market forces. It is not the role of the present document to define standardized applications. A

43、simplified model of the OS1 layers is adopted to facilitate the production of specifications for these nodes. Figure 1 points out the lower layers of the simplified model and identifies some of the key parameters for the lower two layers. Following the user requirements for interactive services, no

In the system model, two channels are established between the service provider and the end

46、 user: Broadcast Channel (BC): an unidirectional broadband broadcast channel that can include audio, low bit-rate video and different types of data. BC is established from the service provider to the end users. It may include the forward interaction path in other words distributing individually addr

47、essed data to the end user. Interaction Channel (IC): a bi-directional interaction channel is established between the service provider and the end user for interaction purposes. It is formed by: - return interaction path (return channel): from the end user to the service provider. It is used for ins

48、tance to make requests to the service provider or to answer questions. In most cases it is a narrow-band channel also commonly known as return channel; forward interaction path: from the service provider to the end user. It is used to provide some sort of individually addressed information by the se

49、rvice provider to the end user and any other required communication for the interactive service provision. It may be embedded into the broadcast channel. It is possible that this channel is not required in some simple implementations which make use of the broadcast channel for the carriage of data to the end user. - The UT is formed by the DAB Receiver Module (DAB-RM), the Interaction Module (IM), the Man Machine Interface (MMI) and the application module. The UT provides interface for both broadcast and interaction channels. The interface between the UT and the intera
