IDvbLinkageDescriptor 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.]

Defines methods that get data from a Digital Video Broadcast (DVB) linkage descriptor. The linkage descriptor appears as part of the DVB service information in the network information table (NIT), bouquet association table (BAT), service description table (SDT), event information table (EIT), or service information table (SIT).

The linkage descriptor identifies a service that can be presented if the consumer requests additional information related to a service. The table that contains the linkage descriptor indicates the entity for which additional information is available. For example, a linkage descriptor in the NIT points to a service that provides additional information on the network, while a linkage descriptor in the BAT links to a service that provides information about the bouquet.

Inheritance

The IDvbLinkageDescriptor interface inherits from the IUnknown interface. IDvbLinkageDescriptor also has these types of members:
