IDvbLogicalChannel2Descriptor 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 logical channel descriptor (LCD) in a Digital Video Broadcast (DVB) MPEG-2 stream that uses the format defined in the Nordig specification used in Scandinavian countries.

The logical channel descriptor may be present in the network information table (NIT).

By default, all methods in the base interface IDvbLogicalChannelDescriptor act on the first item in a list. Once any call to a IDvbLogicalChannel2Descriptor method completes successfully, the item that the method returns remains selected so that subsequent calls to IDvbLogicalChannelDescriptor methods act on the selected item.

Inheritance

The IDvbLogicalChannel2Descriptor interface inherits from IDvbLogicalChannelDescriptor2. IDvbLogicalChannel2Descriptor also has these types of members:

Methods
