The IDVB_SIT interface enables the client to get information from a selection information table (SIT). The IDvbSiParser::GetSIT method returns a pointer to this interface.
The presence of a SIT in a transport stream indicates that the transport stream is partial, meaning the stream contains a subset of a complete broadcast stream. A partial transport stream does not carry any service information (SI) tables other than SITs and discontinuity information tables (DITs). The SIT contains a summary of the full SI information for the stream.
The SIT may contain one or more table-wide descriptors. In addition, each record in the SIT may have one or more descriptors. To get the table-wide descriptors, use the GetTableDescriptorByIndex or GetTableDescriptorByTag method. To get the record descriptors, use the GetRecordDescriptorByIndex or GetRecordDescriptorByTag method.
