/*
 * 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.
