IISDB_CDT 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) common data table (CDT). A CDT contains data, such as company logos, that is needed for receivers and stored in nonvolatile memory.
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 a CDT. 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_CDT interface inherits from the IUnknown interface. IISDB_CDT also has these types of members:
Methods
The IISDB_CDT interface has these methods.
| IISDB_CDT::GetCountOfTableDescriptors Returns the number of descriptors for logos in an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::GetDataModule Receives the data module from an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::GetDataType Receives the data type value from an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::GetDownloadDataId Receives the download_data_id field value for a logo transmission descriptor from an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). The download_data_id field identifies the data to be downloaded. |
| IISDB_CDT::GetOriginalNetworkId Gets an identifier that identifies the broadcaster that originated the MPEG-2 transport stream from an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::GetSectionNumber Gets the section_number field value from an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::GetSizeOfDataModule Gets the size of a data module from an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::GetTableDescriptorByIndex Returns a specified logo transmission descriptor from an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::GetTableDescriptorByTag Searches a subtable in an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::GetVersionHash Returns a hash value for this instance of an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::GetVersionNumber Gets the version number for an Integrated Services Digital Broadcasting (ISDB) common data table (CDT). |
| IISDB_CDT::Initialize Initializes the object by using captured table section data from an Integrated Services Digital Broadcasting System (ISDB) common data table (CDT). |
