IISDB_LDT interface (dvbsiparser.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
Implements methods that get information from an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). An LDT contains data used to collect reference information from other tables.
To obtain a pointer to this interface, first make sure that the media graph is in a running state and that the stream you are tuned to contains an LDT. Then:
- Query the BDA MPEG-2 Transport Information Filter to obtain a pointer to the IPSITables interface. (You can also go through the graph and query each filter until you find one that supports IPSITables.)
- Call the IPSITables::GetTable method. The interface pointer for the desired table is returned in the ppIUnknown output parameter.
Inheritance
The IISDB_LDT interface inherits from the IUnknown interface. IISDB_LDT also has these types of members:
Methods
The IISDB_LDT interface has these methods.
| IISDB_LDT::GetCountOfRecords Gets the number of records in an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). An LDT contains data used to collect reference information from other tables. |
| IISDB_LDT::GetOriginalNetworkId Gets an identifier that identifies the broadcaster that originated the MPEG-2 transport stream from an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). |
| IISDB_LDT::GetOriginalServiceId Gets the original_service_id field from an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). |
| IISDB_LDT::GetRecordCountOfDescriptors Returns the number of descriptors for a record in an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). |
| IISDB_LDT::GetRecordDescriptionId Gets the record description ID from an Integrated services Digital Broadcasting System (IDBS) linked description table (LDT). The description ID field identifies a collected description in the LDT. |
| IISDB_LDT::GetRecordDescriptorByIndex Returns a descriptor for a specified record in an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). |
| IISDB_LDT::GetRecordDescriptorByTag Searches a record in an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT) for a specific descriptor tag. |
| IISDB_LDT::GetTransportStreamId Returns the transport stream identifier (TSID) for an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). |
| IISDB_LDT::GetVersionHash Returns a hash value for this instance of an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). |
| IISDB_LDT::GetVersionNumber Gets the version number for an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). |
| IISDB_LDT::Initialize Initializes the object using captured table section data for an Integrated Services Digital Broadcasting (ISDB) linked description table (LDT). |
