IEEE 1394 is a high-bandwidth isochronous (real-time) interface for computers, peripherals, and consumer electronics products such as camcorders, VCRs, printers, PCs, TVs, and digital cameras. With IEEE 1394-compatible products and systems, users can transfer video or still images from a camera or camcorder to a printer, PC, or television, with no image degradation. IEEE 1394 enables one cable to simultaneously carry digital video signals, digital audio signals, computer data and control signals. Cables are available in a variety of lengths. There are three types of connectors/ports:

• 6-pin (Firewire 400. Can act as a power source for peripheral devices).
• 4-pin (Firewire 400. Does not provide power to peripheral devices).
• 9-pin (Firewire 800. Can act as a power source for peripheral devices).

6-pin to 6-pin. 9-pin to 9-pin. 6-pin to 4-pin. 9-pin to 6-pin. 4-pin to 4-pin. 9-pin to 4-pin.
