Digital Video (DV) is a
digital video format launched in
1994, and, in its smaller tape form factor MiniDV, has since become a standard for home and semiprofessional video production; it is sometimes used for professional purposes as well, such as
filmmaking and
electronic news gathering (ENG). The DV specification (originally known as the Blue Book, current official name
IEC 61834) defines both the
codec and the tape format. Features include intraframe compression for uncomplicated editing, a standard interface for transfer to
non-linear editing systems (
FireWire, also known as IEEE 1394), and good video quality, especially compared to earlier consumer analog formats such as
8 mm,
Hi8 and
VHS-C. DV now enables filmmakers to produce movies inexpensively, and is strongly associated with
independent film and
citizen journalism.
