-          This driver allows you to transmit and receive DV (digital video)
-          streams on an OHCI-1394 card using a simple frame-oriented
-          interface.

-          The user-space API for dv1394 is documented in dv1394.h.

-          To compile this driver as a module, say M here: the
-          module will be called dv1394.
+          The dv1394 driver will be removed from Linux in a future release.
+          Its functionality is now provided by raw1394 together with libraries
+          such as libiec61883.
