FireWire 800
FireWire 800, also called IEEE 1394b, is the next generation of FireWire after IEEE 1394a, a
higher-bandwidth version capable of data transfer speeds of up to 800 Mbps. FireWire
800 is also capable of supporting cable distances of up to 100 meters.
In addition to the standard 9-pin-to-9-pin FireWire 800 cables, 9-pin-to-4-pin and
9-pin-to-6-pin FireWire 400 to FireWire 800 cables are also available to connect older
devices to a FireWire 800 interface.

Note: FireWire 800 is commonly used to connect hard disks and other data peripherals
to your computer, but this connector is rarely used to connect video devices.
SDI
Serial Digital Interface (SDI) is the standard for high-end, uncompressed digital video
formats such as D1, D5, and Digital Betacam. If you want to capture digital video from
these formats at the highest possible quality, you need a video interface with an SDI input
and output, as well as a high-performance disk array (a set of disk drives grouped together
to read and write in parallel), to accommodate the high data rates you’ll work with. Many
devices can send both video and audio data through a single SDI connection.

HD-SDI
High Definition Serial Digital Interface (HD-SDI) is a higher-bandwidth version of SDI
designed for the extremely high data rates required by uncompressed HD video. Like
SDI, HD-SDI is capable of sending both video and audio through a single connection. The
following decks have HD-SDI interfaces: DVCPRO HD, D-5 HD, and HDCAM decks.
Some devices provide even higher data rates by pairing two HD-SDI channels together
(known as dual-link HD-SDI). Uncompressed HD RGB video and other digital cinema
formats can be transmitted using dual-link HD-SDI.
