IDVB_SDT Interface
This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005 and later.
The IDVB_SDT interface enables the client to get information from a service description table (SDT). The IDvbSiParser::GetSDT method returns a pointer to this interface.
An SDT describes one or more services that are carried in a particular transport stream. The services may be carried in the same transport stream that carries the SDT, or a different transport stream.
In addition to the methods inherited from IUnknown, the IDVB_SDT interface exposes the following methods.
| Method | Description |
| ConvertNextToCurrent | Converts a next table to a current table. |
| GetCountOfRecords | Returns the number of records in the SDT. |
| GetNextTable | Retrieves the next table that follows the current table. |
| GetOriginalNetworkId | Returns the original network identifier. |
| GetRecordCountOfDescriptors | Returns the number of descriptors for a record in the SDT. |
| GetRecordDescriptorByIndex | Retrieves a descriptor for a specified record in the SDT. |
| GetRecordDescriptorByTag | Searches a record in the SDT for a descriptor with a specified descriptor tag. |
| GetRecordEITPresentFollowingFlag | Queries whether the current transport stream contains present/following EIT information for a particular service. |
| GetRecordEITScheduleFlag | Queries whether the current transport stream contains schedule EIT information for a particular service. |
| GetRecordFreeCAMode | Queries whether any of the component streams for a particular service are scrambled. |
| GetRecordRunningStatus | Returns the running status of a particular service in the SDT. |
| GetRecordServiceId | Returns the service identifier for a record in the SDT. |
| GetTransportStreamId | Returns the transport stream identifier (TSID) for the SDT. |
| GetVersionHash | Returns a hash value for this table instance. |
| GetVersionNumber | Returns the version number for the SDT. |
| Initialize | Initializes the object. |
| RegisterForNextTable | Registers the client to be notified when a next table arrives that will replace the current table. |
