Foreword This Euro
31、pean Standard (Telecommunications series) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU). ComitC EuropCen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBUJETSI JTC Broadc
32、ast 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 responsible for the standardization of radio and
33、 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 members in about 60 countries in the European broadc

35、. 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 countries around the world. DVB fosters market-led systems. which meet the real needs. and economic circumstances. of the consumer electro

37、icting National Standard (dou): 3 1 January 2007 The present document specifies the Service Information (SI) data which forms a part of DVB bitstreams. in order that the user can be provided with information to assist in selection of services and/or events within the bitstream. and so that the Integ
38、rated Receiver Decoder (IRD) can automatically configure itself for the selected senrice. SI data for automatic configuration is mostly specified within ISOIIEC 13818-1 20 as Program Specific Information (PSI). The present document specifies additional data which complements the PSI by providing dat
39、a to aid automatic tuning of IRDs. and additional information intended for display to the user. The manner of presentation of the information is not specified in the present document. and IRD manufacturers have freedom to choose appropriate presentation methods. It is expected that Electronic Progra
40、mme Guides (EPGs) will be a feature of Digital TV transmissions. The definition of an EPG is outside the scope of the present document (i.e. the SI specification). but the data contained within the SI specified in the present document may be used as the basis for an EPG.
