Video Cables
Coaxial Cable
Coaxial Cable is used for connecting cable and satellite signals, to their respective TV, or receiver. You simply screw it into the back of the television, or receiver, and make sure its snug. Coax can carry analog video signals (antenna TV, older VCRs, or traditional 1st generation game consoles), and digital data (satellite, digital cable, cable internet). The receiver does much of the decoding for high quality applications though, as the cable itself has limited resolution capabilities. The coaxial cable is capable, and will likely be around for many years to come; as cable companies all use coax, as a way to deliver the signal to homes from their satellite locations. But among modern signal delivery cables, coax rates the lowest in quality transfer.
Audio & Video Cable
Audio & Video Cables are red, white and yellow cables that we have all used over the years. They're popularity has dwindled, but were all the rage back in the nineties, when VCRs and gaming consoles adapted HIFI technology. They were also the only way you could view programs with a DVD player, when they first entered the market. They are a step above the quality a coax offers, but the audio quality is still a stereo sound and not particularly capable of Dolby quality sound. They only offer analog signal quality.
S-Video Cable
They produces a slightly improved picture over Audio & Video cable. One end looks similar to a PS/2 mouse connector, with the other end the same as that of the Audio & Video connectors. This is the best type of cable, among the non-HD rated cables. This type of cable showed marked improvement over coax, and Audio Video Cables, but is rarely seen today. Many gaming consoles from the late 90's used S-Video.
Component Video Cables
Component video cables include three separate cables just for video signal, with two others allotted for sound. The three image cables all carry a separate part of the video signal, to preserve the image better. Component video cables are able to carry 480p signals, and make for decent HD video play also. Earlier HD devices like televisions, and DVD players had component connections for progressive scan, 480p. In the first few years of HD. Modern TVs still have two or more component video jacks.
HDMI & DVI
HDMI cables are the new standard in the signal transfer business. They provide an unfettered image, with zero signal loss issue. Developers have made these cables versatile enough to carry 1080p HDTV, and Dolby Digital Surround signals. Pristine video quality, and perfect sound are brought together in one simple cable. Not much needs to be said about them. They are the essence of modern viewing, and listening technology!
