Digital Broadcasting Systems for Television@ Sound and Data Services; Specification for Service Information (SI) in Digital Video Broadcasting (DVB) Systems
This 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). The 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.
