There are available today quite a bewildering array of connection types utilized for Audio and Video. To further complicate things a few of the same connectors and leads can be used for multiple connection types.
This informative guide will start with the very first audio and video connections and move up to Cayin A88t Mk2 and leads. It can give the pros and cons of them all and hopefully at the end you will end up a little bit more informed about how for the best quality images from your setup.
At First – In the beginning things where simpler as there was only a good way to receive TV signals, via an aerial. This connection technique is called Coax and is still used today to connect Freeview Receivers up to the aerial on your own roof (the freeview receiver can either become a separate box or that are part of your TV). Coax cable is what is known as screened cable and is comprised of a good inner wire (core) using a wire mesh or foil surrounding it.
As each of the Video and Audio Details are carried down the same cable Coax is bottom of the pile in terms of quality. Coax cannot be utilized to have a hi-def signal
Composite Video – Composite video is a step-up from Coax in that the photo and Audio details are sent separately. It genuinely requires 3 separate connections (Video, Audio Left and Audio Right) to get made so that you can show an image with sound. The connectors used are referred to as Phono (RCA) connectors and should be immediately familiar to anyone that owns a Hifi Separates System.
Component video continues to be used now to connect such things as Video cameras and Nintendo Wii’s to TV’s. Most TV’s could have a socket on the front or side in order to easily connect equipment to the TV. The photo quality achieved with a composite connection is superior to with Coax but still not great and so is not actually suitable for Hi-Fi Speaker Cable. Composite cannot be used to possess a high-definition signal.
S-Video – S-Video or S-VHS is surely an evolution from the original composite video standard in that instead of all the video data being sent down 2 pieces of wire the picture is divided in to a signal that contains colour data (Chroma) as well as a signal which has brightness data (Luma). This provides a better picture than Composite. Comparable to Composite Video, separate connections are required for Audio and utilize the identical Phono (RCA) connectors as shown above.
S-Video connections could also very often found on the front of recent TV and can utilized to quickly connect equipment such as Camcorders to your TV so that you can show home video footage. S-Video cannot be utilized to carry high-definition signals.
Scart Connections – Scart Connectors where introduced so that you can allow simple single cable connections between video equipment. Scart connections may still be found today on DVD players, Sky boxes and modern TV’s. Nonetheless they are now being eliminated and can not be seen on Hi-def video sources including Bluray players.
Scart is actually a multicored cable that carries many different video connections like Composite and S-Video as well as Right and left Audio Data all conveniently located in a single socket. Generally when using a Scart Connection here is the only connection necessary to connect a source to a display.
Scart cables also introduced a whole new video standard called RGB in which the separate Red, Green and Blue colour signal. This additional separation gives higher quality then Composite or S-Video connections. The RGB video wcmlld eventually become the Component Video standard which is discussed below. Scart cables cannot be employed to carry high-definition video signals.
Component Video (Y, PB, PR) – Component video is definitely an evolution of RGB mentioned previously which uses better quality cable and connectors so you can use it to carry hi-def video signals (720P, 1080i however, not 1080P). Component Video connectors are Phono (RCA) connectors as stated before for Composite Video but remember that the cable differs.
Component video connections are the best quality Analogue (i.e. none digital) connections available. Component Video connections are available on all High Definition equipment i.e. HD TV’s, Bluray Players etc. Component Video Cables can be used for Line Magnetic but please be aware that they cannot be employed to carry 1080P signals.
