+/*
+ * VIDIX - VIDeo Interface for *niX.
+ *
+ * This interface is introduced as universal one to MPEG decoder,
+ * Back End Scaler (BES) and YUV2RGB hw accelerators.
+ *
+ * In the future it may be expanded up to capturing and audio things.
+ * Main goal of this this interface imlpementation is providing DGA
+ * everywhere where it's possible (unlike X11 and other).
+ *
+ * This interface is based on v4l2, fbvid.h, mga_vid.h projects
+ * and personally my ideas.
+ *
+ * NOTE: This interface is introduced as driver interface.
