Looking at the rear area of an HDTV television can be a frightening experience for those that are technologically handicapped. The many connection options and different connecting interfaces that are available in most of the sets that are being produced today can really scare the uninitiated away.
The truth is that the vast majority of people only use two or maybe three of these interfaces. Still, manufacturers include mostly all of the interfaces that are available even if they are not very popular to avoid losing one customer over compatibility issues with other devices they own. These are the four most important connection types that are available in HDTV televisions:
Composite: Composite connections are the now classic RCA A/V Jack. They use three cables; one yellow video cable, and two audio cables (red and white). They are very handy when it comes to connecting DVD players, MP3 and video game consoles.
DVI : DVI connections only transmit video and are useful to connect computers. This is a video only interface and you need to make audio connections separately.
HDMI: HDMI is the best connection that is currently available when it comes to High Definition. It is used to connect Blu-Ray players, computer and High Definition camcorders. HDMI uses only one cable and does not require additional audio cables.
Coaxial: This is the connection that is used to connect antennas and cable television most of the time. It uses only one cable for both video and audio. This is the usual black screw-on cable that has been around for more than 20 years.
These four interfaces that are used most of the time. HDTV televisions that have these connections are compatible with practically all the devices related to audio and video that you may have in you home. Although some devices may require and USB connection or an SD card slot.
