backup tool using MiniDV camcorders

Dvbackup hides the data it receives on standard input in a perfectly legal DV (digital video) stream. This allows you to use your DV camcorder and your DV cardridges as a potent mass storage system. Obviously, your system and your camcorder have to be connected via IEEE1394 (aka Firewire, iLink).

Current digital camcorders can save approximately 13 GB of data on those tiny DV cartridges at a speed of 3.6 MB/sec. That's faster than most DAT streamers which only work at 1 MB/sec or less. dvbackup can not use all of the data, but 10 GB should be good enough for everyone.

To bring the data on tape, you have to use an additional utility, called dvconnect, which is included in libdv-bin.

This packages also contains rsbep, an implementation of a special version of the Reed-Solomon FEC (forward error correction) algorithm. rsbep also spreads the bytes of the resulting blocks out to give some protection against burst errors (e.g from tape-recordings). It should be used in a pipe together with dvbackup (before dvbackup while encoding and after it while decoding). rsbep should be sufficient to make the LP mode of your camcorder usable. This mode, which puts about 50% more data on the cardridge would otherwise be too error-prone. rsbep is the fast implementation in i386 assembler, rsbepC uses pure C and is significantly slower (about ten times).
