IDvbDataBroadcastDescriptor 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 data from a Digital Video Broadcast (DVB) data broadcast descriptor. The data broadcast descriptor appears in the DVB service information as part of the service description table (SDT) or event information table (EIT) and identifies the type of the data component.
Inheritance
The IDvbDataBroadcastDescriptor interface inherits from the IUnknown interface. IDvbDataBroadcastDescriptor also has these types of members:
Methods
The IDvbDataBroadcastDescriptor interface has these methods.
| IDvbDataBroadcastDescriptor::GetComponentTag Gets the component tag from a Digital Video Broadcast (DVB) data broadcast descriptor. The component tag identifies a component stream within the service. |
| IDvbDataBroadcastDescriptor::GetDataBroadcastID Gets the identifier that identifies the network broadcast from a Digital Video Broadcast (DVB) data broadcast descriptor. |
| IDvbDataBroadcastDescriptor::GetLangID Gets the three-character ISO 639 language code from a Digital Video Broadcast (DVB) data broadcast descriptor. This language code identifies the language used for the text description field. |
| IDvbDataBroadcastDescriptor::GetLength Gets the length of a Digital Video Broadcast (DVB) data broadcast descriptor, in bytes. |
| IDvbDataBroadcastDescriptor::GetSelectorBytes Gets the data from the selector in a Digital Video Broadcast (DVB) data broadcast descriptor. The selector is defined by the broadcast standard for the network. |
| IDvbDataBroadcastDescriptor::GetSelectorLength Gets the length of the selector in a DVB data broadcast descriptor, in bytes. The selector is defined by the data broadcast specification for the network. |
| IDvbDataBroadcastDescriptor::GetTag Gets the tag that identifies a Digital Video Broadcast (DVB) data broadcast descriptor. |
| IDvbDataBroadcastDescriptor::GetText Gets the text that describes the data from a Digital Video Broadcast (DVB) data broadcast descriptor. |
| IDvbDataBroadcastDescriptor::GetTextLength Gets length of the text description, in bytes, from a Digital Video Broadcast (DVB) data broadcast descriptor. |
