eSATA is a bus technology designed to connect external mass storage
devices, such as hard drives and optical drives, to your computer. eSATA
provides considerably higher throughput as compared to USB 2.0 or
FireWire 800. eSATA cables can be up to 2 meters long.
eSATA ports can be standalone or can be present in the form of an
eSATA/USB combo port.
S/PDIF is a standard for transferring audio in digital format.
You can connect the S/PDIF output from your computer to the S/PDIF
input on your home theater receiver. This connection allows you to set
up a 5.1 audio (also known as 6-channel audio) connection.
There are two kinds of S/PDIF connections:
• Optical – Set up by optical fiber with TOSLINK connectors
• Coaxial – Set up by coaxial cable with RCA connectors
The IEEE 1394 interface is a serial bus interface standard and enables
simple, low-cost, high-bandwidth isochronous (real-time) data
interaction between computers, peripherals, and consumer electronics
products such as camcorders, VCRs, printers, TVs, and digital cameras.
With IEEE 1394-compatible products and systems, you can transfer video
or still images without losing quality.
• Digital – Provides better signal quality as it does not require
• Connectivity – Uses a thin serial cable that, through the use of
repeaters, can be extended to 100 meters or more over CAT5,
fiber optic, or coaxial cables.
• Easy to use – Eliminates the need for special drivers or perform
• Hot pluggable – Enables devices to be added and removed while the
device and computer are turned on.
