IEEE 1394 (FireWire)
IEEE-1394 is a high speed serial digital interfacing standard used to transfer digital video signals from one piece of equipment to another. The technology was developed by Apple and is also known as FireWire or iLink.
It can transmit at data rates of up to 400Mb/s, more than enough to handle MPEG1 or MPEG2 compressed digital bitstreams, and sufficient for some uncompressed digital video formats. Updated versions allow a transfer rate of close to 800Mb/s. A typical IEEE-1394 interface cable may have two shielded TWP cables for bidirectional information transfer, plus two optional additional wires for supply of DC power. This type of cable can convey digital video bitstreams over distances up to about 4.5m.
