The WST Decoder is a kernel-mode filter that accepts decoded World Standard Teletext data from the WST Codec and delivers the bitmaps to Pin 2 on the Overlay Mixer using fonts supplied by Microsoft. Only Western European languages are supported at this time; no Unicode fonts are currently provided.
This filter can be added to the graph automatically by calling ICaptureGraphBuilder2::RenderStream, using the output pin of the WST Codec.
