The HDTV Component Cable was invented alongside the creation of high-definition television by Nippon Hyoso Kyokai in the year 1969. In the early years of the new millennium, a number of component cables for high-definition television are now being used as a standard for gradually developing niche markets. The HDTV Component Cable provides televisions with theater-quality sounds that can totally enhance viewing experience. In some instances, the component cable even displays a better picture, due to the problems that are still occurring with HDMI. DVD's are also great for the component cables, the picture is crystal clear and fantastic compared to the A/V or S-Video connections. Component Video Cable Component video is a video signal that has been split into two or more components. When used without any other qualifications the term component video generally refers to analog YPbPr component video with sync on luma. When a signal is separated this way it is called 'component video'. Component video is capable of carrying signals such as 480i, 480p, 576i, 576p, 720p, 1080i and 1080p[1], and new high definition TVs support the use of component video up to their native resolution. A full composite sync video signal requires four wires †red, green, blue, sync. The YPbPr scheme is usually what is meant when people talk of component video today. Hence, a common complaint is that the component video signals are very green, with very dark reds and blues. Naturally, people want to know: what makes the best component video cable. How can I choose the component video cable that will do the best job in my system. At one extreme is composite video; all of the information, from the sync pulses used to deliver scan information to the luminance (brightness) and chrominance (color) portions of the signal are all delivered as one unified, "composite" signal, traveling down one wire. Not too surprisingly, when component and RGB video came into common use, the same type of cable was used to hook them up--the difference being, of course, that when there are three signals, as in a Y/Pb/Pr component video cable run, one needs three cables to run them in. Hdmi HDMI contains audio and video, DVI only connects video, for DVI you would need seperate audio connectors. HDMI cables not only do video and audio but can carry 10 bit and even up to 12 bit video transmissions. HDMI is just a more portable format and more convenient due to size and the fact that it includes the audio signal. HDMI does have some advantages over component but the hardware handshaking issues with pieces of kit that are at spec wipes them out. HDMI is all about closing that last Analog Loop hole. First, to clear away one element that can be confusing: DVI and HDMI are exactly the same as one another, image-quality-wise. The principal important difference is that DVI/HDMI deliver the signal in a digital format, much the same way that a file is delivered from one computer to another along a network, while Component Video is an analog format, delivering the signal not as a bitstream, but as a set of continuously varying voltages representing (albeit indirectly, as we'll get to in a moment) the red, green and blue components of the signal. I have had several debates with so-claimed audio/video experts on the use of HDMI/DVI versus Component and around the subject of upscaling. Component connections ALWAYS have poorer display results compared to DVI or HDMI. Some HDMI outputs on dvd players and set top boxes cannot upscale to 1080i. component cables, component video cables show Connects DVDs, DVRs other audio/video equipment to televisions or receivers equipped with component composite audio connections. DVD's are also great for the component cables, the picture is crystal clear and fantastic compared to the A/V or S-Video connections. You need to have these component cables if you have a hdtv and are still using a composite video or s-video cable. There is no doubt that the component cable improves the picture. There are actually three HDTV standards that maintain the quality of a specific HDTV Component Cable being produced in the market. Given decent quality component cables, with reasonable lengths typical of a home user, component will look just as good as DVI, or HDMI.
