BDA Network Provider Filter
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The BDA Network Provider is the source filter for any digital television filter graph based on Microsoft Broadcast Driver Architecture (BDA). The following Network Provider filter is available. The Microsoft Network Provider Filter supports all legacy network providers.

Remarks
The Network Provider acts as the default tuner in a BDA filter graph, by exposing the ITuner interface. No signals or data actually pass through this filter. It works closely with the Transport Information Filter (TIF) and the MPEG-2 Demultiplexer to acquire transport streams and route the elementary stream to the appropriate downstream filters.
If you are creating a digital TV graph manually (rather than using the Video Control), use CoCreateInstance and IFilterGraph::AddFilter to add this filter to the graph. The ICaptureGraphBuilder2 interface does not automatically add this filter to the graph.
