The IDVB_NIT interface enables the client to get information from a network information table (NIT). The IDvbSiParser::GetNIT method returns a pointer to this interface.
A NIT contains information about the network and the physical organization of the transport streams. Because a network typically carries more than one transport stream, the NIT can provide information for tuning and for locating particular transport streams. A NIT carried on one network may contain information about another network.
The original_network_id and transport_stream_id fields together uniquely define a transport stream within the network.
The NIT may contain one or more table-wide descriptors. In addition, each record in the NIT 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.
