If you’re using DVI-D connections, watch out for two problems:

• Not all DVI connectors work with HDTV. Make sure you have DVI-D cables if you use DVI-D in your HDTV system.
  
  Computers use another type of DVI connector that has a confusingly similar name: DVD-I. The DVD-I connector has five extra pins (four pins around a central crosshair-shaped pin) on one side; these send analog video signals from computer video cards to computer monitors. You typically won’t find DVI-I in home HDTV systems. (There are some projection systems that are also used with computers to beam PowerPoint slides up onto the conference room wall.) You can use an inexpensive adapter to connect a DVD-I cable to the DVD-D receptacle on your HDTV _but you’ll only be able to receive digital video signals that way, not analog.
• DVI-D connections often require the HDCP copy protection system for true HDTV video performance. If just one of your HDTV components doesn’t have HDCP, you may not get true HDTV performance from DVI-D connections. DVI-D is the only digital HDTV connection that can’t carry audio.

HDMI
The HDMI system (for High-Definition Multimedia Interface) is specially designed for HDTV connections. It carries both HDTV video and digital surround sound.

HDMI has a couple of advantages in an HDTV system:

• You need only one HDMI cable to connect both HDTV video and surround-sound digital audio signals. HDMI is an extremely high-bandwidth technology (5 gigabits per second). It has extra bandwidth to accommodate future HDTV formats.
• HDMI connections often require the HDCP copy-protection system for true HDTV video performance. If you’re using any HDMI connections, make sure that all your HDTV components support HDCP.

FireWire
FireWire is the least-used HDTV connector. It can transmit both video and audio. FireWire is the only two-way connection for HDTV _the same cable can send HDTV video (and audio) to and from devices. This two-way connection is great for HDTV recording systems _for example, one cable fully connects an HDTV with a D-VHS VCR.

The name FireWire _the same system is known by a couple of other names:

• Engineers and nerds call FireWire the IEEE 1394Standard. (IEEE is the Institute of Electrical and Electronic Engineers.)
• Some manufacturers use the name i.LINK instead of FireWire. Consumer-electronics manufacturers usually prefer a snappy name like i.LINK or FireWire over something boring like 1394.

Some DVD players hold high-definition connectors. However, none of these were HDTV DVD players. Instead, a circuit called a scaler converts the standard DVD picture to work a little renovate on an HDTV screen. It’s a worthwhile improvement, but you probably should use all your high-definition connections for pure HDTV components before you use a high-definition connection on a DVD player.

Digital connections
Digital video connections ( such as DVI-D, HDMI and FireWire ) are the elite preference for often – used HDTV video connections, such as the link to your HDTV from a satellite or cable receiver.

Not all HDTV devices use the same digital connections, but it’s usually worth the mishap to use digital connections when you can, even if you scarcity an adapter for different digital connections. As the HDMI connection replaces DVI-D, you may find yourself in a situation where you want to use an inexpensive adapter. For example, if your HDTV has an HDMI connector and your HDTV coagulate top box or tuner uses DVI – D, you can connect your devices through one of these converters.

The top rule of HDTV connections: Use a digital video connection to connect from a source device to your HDTV, if you can. Digital connections halfway always provide the finest picture.

Theoretically, HDMI connections can proposal the best representation superiority of any of the digital connections available on HDTVs, simply because these cables own so much bandwidth that they can proposition uncompressed HDTV signal transmission. In the veritable universe, however, any of these digital connections offers an exceptionally clear and sharp picture, and HDTV signals are halfway always compressed for transmission or storage anyway.

On some pieces of gear, some of the digital connections may be limping _the connections are physically present, but the software within the device that lets them work is bad off. So, for example, if an HDTV coagulate – top box from your cable company has a FireWire port, you probably can’t use that FireWire port to connect a D-VHS recorder. Inspection with your cable company before spending money on cables and equipment that use these ports!
