You will find available today quite a bewildering array of connection types used for Audio and Video. To further complicate things some of the same connectors and leads can be used for multiple connection types.
This guide will begin with the first audio and video connections and move up to Cayin A88t Mk2 and leads. It will give the advantages and disadvantages of those all and hopefully at the end you will be a little bit more informed about how for the best quality images from your setup.
At First – At first things where simpler since there was just one way to receive TV signals, with an aerial. This connection strategy is called Coax and is still used today to connect Freeview Receivers up to the aerial on the roof (the freeview receiver either can become a separate box or that are part of your TV). Coax cable is what is known as screened cable and is made up of a solid inner wire (core) having a wire mesh or foil surrounding it.
As all the Video and Audio Information is carried on the same cable Coax is bottom of the pile with regards to quality. Coax cannot be used to carry a high definition signal
Composite Video – Composite video is really a step up from Coax in this the photo and Audio information is sent separately. It actually requires 3 separate connections (Video, Audio Left and Audio Right) to get made to be able to show a picture with sound. The connectors used are classified as Phono (RCA) connectors and should be immediately familiar to anybody who owns a Hifi Separates System.
Component video is still 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 to be able to easily connect equipment to the TV. The picture quality achieved by way of a composite connection is preferable to with Coax but nonetheless not great and thus is not really suitable for Audiophile Cables. Composite cannot be used to have a hi-def signal.
S-Video – S-Video or S-VHS is definitely an evolution in the original composite video standard because instead of all the video data being sent down 2 pieces of wire the image is divided right into a signal which contains colour data (Chroma) along with a signal which has brightness data (Luma). This gives a much better picture than Composite. Comparable to Composite Video, separate connections are needed for Audio and make use of the identical Phono (RCA) connectors as shown above.
S-Video connections may also quite often found on the front of contemporary TV and will employed to quickly connect equipment such as Camcorders to a TV to be able to show home video footage. S-Video cannot be utilized to carry high-definition signals.
Scart Connections – Scart Connectors where introduced to be able to allow simple single cable connections between video equipment. Scart connections may still be found today on DVD players, Sky boxes and modern TV’s. But they are being phased out and should not be available on High-definition video sources like Bluray players.
Scart is a multicored cable that carries a number of video connections such as Composite and S-Video along with Right and left Audio Data all conveniently located in a single socket. Generally when you use a Scart Connection here is the only connection needed to connect a source to your display.
Scart cables also introduced a brand new video standard called RGB wherein 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 evolved into the Component Video standard which is discussed below. Scart cables cannot be utilized to carry high definition video signals.
Component Video (Y, PB, PR) – Component video is an evolution of RGB mentioned previously which uses better quality cable and connectors so you can use it to transport hi-def video signals (720P, 1080i although not 1080P). Component Video connectors are Phono (RCA) connectors as pointed out above for Composite Video but be aware that the cable differs.
Component video connections are the most effective 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 219ia but please bear in mind that they cannot be used to carry 1080P signals.
