The IDvbServiceDescriptor interface enables the client to get a service descriptor from a DVB stream. The service descriptor may be present in the service description table (SDT). For more information, refer to ETSI EN 300 468.
Methods
The IDvbServiceDescriptor interface inherits the methods of the IUnknown interface.
In addition, IDvbServiceDescriptor defines the following methods.
| Method | Description |
|---|---|
Returns the length of the descriptor body. |
|
Returns the service name converted into a readable string. |
|
Returns the raw service name. |
|
Returns the emphasized version of the service name. |
|
Returns the raw service provider name. |
|
Returns the service provider name converted into a readable string. |
|

Remarks
To obtain a pointer to this interface, do the following:
- Call IDvbSiParser::GetSDT to get the IDVB_SDT interface.
- Call IDVB_SDT::GetRecordDescriptorByTag and pass in the logical channel descriptor tag (0x47). If the descriptor is present, the method returns an IGenericDescriptor pointer.
- Query the returned IGenericDescriptor pointer for the IDvbServiceDescriptor interface.
