Foreword This European Standard (Telecommunications series) has been produced by the Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) an
11、d the European Telecommunications Standards Institute (ETSI). NOTE: 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 Memorandu
12、m of 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
13、-exchange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva.

14、n September 1993, the DVB Project is a marked-led consortium of public and private sector organizations in the television industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television services. Now comprising over 200 organizations from more than 25 countrie
15、s around the world, DVB fosters marked-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast industry.

17、aseline specification for the provision of an interaction channel based on Global System for Mobile communications (GSM) to Digital Video Broadcasting (DVB) systems. The DVB project does not intend to specify an interaction channel solution associated to each broadcast system because the interoperab
18、ility of different delivery media to transport the interaction channel is desirable. Therefore the GSM solution for the interaction channel apply to satellite, cable, MATV, SMATV, terrestrial, microwave or any future DVB broadcasting or distribution system. The solutions provided in the present docu
19、ment for an interaction channel through GSM are a part of a wider set of alternatives to implement interactive services for DVB systems. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

The present document addresses the lower two layers (the physical and transport layers), leaving the application layer open to competitive market forces. A simplified model of the OS1 layers was adopted to facilitate the
41、production of specifications for these nodes. Figure 1 points out the lower layers of the simplified model and identifies some of the key parameters.

44、odel which is to be used within DVB for interactive services. In the system model, two channels are established between the service provider and the user: - Broadcast Channel (BC): A unidirectional broadband BC including video, audio and data. BC is established from the service provider to the users
45、. It may include the forward interaction path. Znreruction Channel (IC): A bi-directional IC is established between the service provider and the user for interaction purposes. It is formed by: - - Return interaction path (return channel): From the user to the service provider. It is used to make req
46、uests to the service provider or to answer questions. It is a narrowband channel. Also commonly known as return channel. - Forwurd interaction path: From the service provider to the user. It is used to provide some sort of information by the service provider to the user and any other required commun
47、ication 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 user.

49、Module (IIM) and the Set Top Unit (STU). The user terminal provides interfaces for both broadcast and interaction channels. The interface between the user terminal and the interaction network is via the Interactive Interface Module (IIM).
