Digital Broadcasting Systems for Television@ Sound and Data Services; Specification for Service Information (SI) in Digital Video Broadcasting (DVB) Systems Second Edition
This 2nd edition of European Telecommunication Standard (ETS) 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 Integrated Receiver Decoder (IRD) can automatically configure itself for the selected service. SI data for automatic configuration is mostly specified within ISO/IEC 13818-1 [1] as Program Specific Information (PSI). This ETS specifies additional data which complements the PSI by providing data 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 this ETS@ and IRD manufacturers have freedom to choose appropriate presentation methods. It is expected that Electronic Programme Guides (EPGs) will be a feature of Digital TV transmissions. The definition of an EPG is outside the scope of the SI specification@ but the data contained within the SI specified here may be used as the basis for an EPG. Rules of operation for the implementation of ETS 300 468 are specified in ETR 211 [7].
