The IGuideDataEvent interface is an IConnectionPoint notification callback interface that is implemented on the BDA Network Provider filter, a Guide Store Loader, or any other object that needs to receive these events from the BDA MPEG-2 Transport Information Filter (TIF) The event consumer must not block the calling thread. If the consumer requires additional information about the event, it should queue the event to a separate thread.
