The IDVB_BAT interface enables the client to get data from a bouquet association table (BAT). The IDvbSiParser::GetBAT method returns a pointer to this interface.
A bouquet is a collection of services that are marketed as one entity. A single bouquet may contain several transport streams that are delivered across different distribution media (satellite, cable, or terrestrial).
The BAT may contain one or more table-wide descriptors. In addition, each record in the BAT 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.
