The format was first called DVC (as in Digital Video Cassette), later it was called simply DV. It is used in many consumer and professional grade digital camcorders.
Digital video (DV) can be captured from a DV camcorder, stored in a file on the user's computer, or stored on tape using a video tape recorder (VTR).
On Windows, DirectShow based DV capture program normally capture the DV into an AVI file. However, QuickTime based software would generally create a .DV file without the AVI header.
