Component cables have three connectors for your TV. One cable has three separate wires, each of which goes into a separate port. The wires are red, green and blue. Component cables provide a high-definition connection between HD devices. Component cables only provide video, so you need a separate audio cable in addition to this cable.
S-video Cables
An S-Video cable provides a standard-definition video connection but has a slightly better picture than a composite cable. This cable type only provides video and requires a separate audio cable. S-Video cables do not provide high-definition video. The most common S-Video connector is a four-pin mini DIN connector. Seven-pin connectors also are available.
HDMI Cables
HDMI stands for high-definition multimedia interface. HDMI cables connect your converter to your HDTV. HDMI cables also make it possible to connect your TV to your laptop and use your TV as a computer monitor. HDMI provides both audio and video, eliminating the need for extra cables.
DVI Cables
DVI stands for digital visual interface. DVI cables most often connect a video source to a computer monitor. These cables only provide video, so you need a separate audio cable. DVI cables come in two types. The DVI-D cable provides a digital signal. The DVI-I cable provides an analog signal.
Coaxial Cables
A coaxial cable connects your wall outlet to your TV or converter. This cable provides a signal for TV, high-speed Internet and home phone. A coaxial cable is often known simply as a cable wire. A coaxial cable consists of a conducting shield and an insulating layer that surrounds an inner conductor. A plastic outer jacket protects the cable interior.
