There are 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.
The following information will start with the 1st audio and video connections and move up to Cayin Audio and leads. It can give the advantages and disadvantages of those all and hopefully by the end you will be a little more informed about how for the best quality images from your setup.
At First – In the beginning things where simpler because there was only a good way to receive TV signals, with an aerial. This connection technique is called Coax and it is still used today for connecting Freeview Receivers as much as the aerial on your own roof (the freeview receiver either can become a separate box or built into your TV). Coax cable is what is known as screened cable and is comprised of a good inner wire (core) having a wire mesh or foil surrounding it.
As all of the Video and Audio Information is carried down the same cable Coax is bottom in the pile in terms of quality. Coax cannot be used to have 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 really requires 3 separate connections (Video, Audio Left and Audio Right) to be made so that you can show a picture with sound. The connectors used are referred to as Phono (RCA) connectors and must be immediately familiar to anyone that owns a Hifi Separates System.
Component video continues to be used now to connect things such as Video cameras and Nintendo Wii’s to TV’s. Most TV’s could have a socket on the front or side so that you can easily connect equipment for the TV. The image quality achieved by way of a composite connection is better than with Coax but nonetheless not great and thus is not actually suitable for HiFi XLR cable. Composite cannot be utilized to have a high-definition signal.
S-Video – S-Video or S-VHS is surely an evolution of the original composite video standard because instead of all the video data being sent down 2 bits of wire the image is divided in to a signal which has colour data (Chroma) as well as a signal which has brightness data (Luma). This gives a much better picture than Composite. Comparable to Composite Video, separate connections are required for Audio and utilize exactly the same Phono (RCA) connectors as shown above.
S-Video connections may also very often found on the front of contemporary TV and can employed to quickly connect equipment like Camcorders to some TV to be able to show home video footage. S-Video cannot be employed 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 can still be found today on DVD players, Sky boxes and modern TV’s. But they are being eliminated and can not be available on High Definition video sources such as Bluray players.
Scart is a multicored cable that carries a variety of video connections such as Composite and S-Video along with Left and Right 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 some display.
Scart cables also introduced a new video standard referred to as RGB in which the separate Red, Green and Blue colour signal. This additional separation gives better quality then Composite or S-Video connections. The RGB video wcmlld eventually evolved into the Component Video standard which can be 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 stated earlier which utilizes better quality cable and connectors so it can be used to hold hi-def video signals (720P, 1080i although not 1080P). Component Video connectors are Phono (RCA) connectors as stated before for Composite Video but bear in mind that the cable differs.
Component video connections are the most useful quality Analogue (i.e. none digital) connections available. Component Video connections can be obtained on all Hi-def equipment i.e. HD TV’s, Bluray Players etc. Component Video Cables can be used as Line Magnetic 219ia but please bear in mind that they cannot be employed to carry 1080P signals.
