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.
