Foreword This ETSI Standard (ES) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (

16、ETSI)(Broadcast). NOTE 1: The EBU/ETSI 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 Understanding also CENELEC, which is

17、 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-exchange domains. The EBU has active mem

18、bers in about 60 countries in the European broadcasting area; its headquarters is in Geneva.

19、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 147 are drawn from broadcasting orga

20、nizations and telecommunication providers together with companies from the professional and consumer electronics industry.

21、al 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 variety of future interactive services, th

22、rough 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 service consumers and low bitrate interac

23、tion 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 services with interactivity. At the simplest

24、 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-mail) on-demand, both via the broadcas

25、t 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. The specification of the network de

26、pendent 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 compatible with the DVB solutions thereby cr

27、eating 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 The following documents contain provis

40、For asymmetric interactive services supporting broadcast to mobile/portable/stationary receivers with a narrowband return channel, a simple communication model consists of the following layers: application layer: is the interactive application software and runtime environments (e.g. home shopping ap

41、plication, script interpreter, etc.). transport layer: defines all the relevant data structures and communication protocols. physical layer: where all the physical (electrical) transmission parameters are defined. The present document addresses the lower two layers (the physical and transport) leavi

42、ng the application layer open to competitive market forces. It is not the role of the present document to define standardized applications. A 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 simp

43、lified model and identifies some of the key parameters for the lower two layers. Following the user requirements for interactive services, no attempt will be made to consider higher layers in the present document.

45、 is to be used within DAB for interactive services. In the system model, two channels are established between the service provider and the end user: Broadcast Channel (BC): an unidirectional broadband broadcast channel that can include audio, low bit-rate video and different types of data. BC is est

46、ablished from the service provider to the end users. It may include the forward interaction path in other words distributing individually addressed data to the end user. Interaction Channel (IC): a bi-directional interaction channel is established between the service provider and the end user for in

47、teraction purposes. It is formed by: - return interaction path (return channel): from the end user to the service provider. It is used for instance 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; forwar

48、d interaction path: from the service provider to the end user. It is used to provide some sort of individually addressed information by the service provider to the end user and any other required communication for the interactive service provision. It may be embedded into the broadcast channel. It i

49、s 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 interaction network is via the interaction module.
