Applications can use this interface to reduce the frame rate on a DV stream, before the stream reaches the DV Video Decoder filter. This can be helpful for processor-intensive tasks, such as real-time transcoding.

In addition to the methods inherited from IUnknown, the IDVSplitter interface exposes the following method.
