You will find available today quite a bewildering variety of connection types used for Audio and Video. To further complicate things a few of the same connectors and leads can be used for multiple connection types.
The following information begins with the 1st audio and video connections and progress up to Cayin 300B and leads. It can give the advantages and disadvantages of those all and hopefully by the end you will be a little bit more informed about how exactly to get the best quality images from your setup.
In The Beginning – In the beginning things where simpler because there was only one method to receive TV signals, with an aerial. This connection method is called Coax and it is still used today to connect Freeview Receivers approximately the aerial on your own roof (the freeview receiver may either be a separate box or that are part of your TV). Coax cable is what is known as screened cable and is made up of an excellent inner wire (core) having a wire mesh or foil surrounding it.
As each of the Video and Audio Information is carried along the same cable Coax is bottom in the pile in terms of quality. Coax cannot be utilized to have a high definition signal
Composite Video – Composite video is actually a boost from Coax because the photo and Audio details are sent separately. It genuinely requires 3 separate connections (Video, Audio Left and Audio Right) to be made in order to show an image with sound. The connectors used are known as Phono (RCA) connectors and should be immediately familiar to anybody who owns a Hifi Separates System.
Component video remains used now to connect things such as Video cameras and Nintendo Wii’s to TV’s. Most TV’s may have a socket on the front or side to be able to easily connect equipment for the TV. The image quality achieved with a composite connection is superior to with Coax but still not great therefore is not actually appropriate for Audiophile Cables. Composite cannot be used to have a hi-def signal.
S-Video – S-Video or S-VHS is surely an evolution of the original composite video standard in that instead of all of the video data being sent down 2 pieces of wire the photo is split up in to a signal which has colour data (Chroma) as well as a signal that contains brightness data (Luma). This gives an improved picture than Composite. Similar to Composite Video, separate connections are needed for Audio and utilize the same Phono (RCA) connectors as shown above.
S-Video connections could also quite often found on the front of contemporary TV and may utilized to quickly connect equipment including Camcorders to some TV so that you can show home video footage. S-Video cannot be employed 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 eliminated and cannot be found on High-definition video sources such as Bluray players.
Scart is a multicored cable that carries a variety of video connections including 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 this is the only connection necessary to connect a source to your display.
Scart cables also introduced a whole new video standard referred to as 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 that is discussed below. Scart cables cannot be used to carry high-definition video signals.
Component Video (Y, PB, PR) – Component video is definitely an evolution of RGB stated earlier which uses higher quality cable and connectors so it can be used to hold high definition video signals (720P, 1080i but not 1080P). Component Video connectors are Phono (RCA) connectors as stated before for Composite Video but be aware that the cable is different.
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 Line Magnetic but please remember that they cannot be used to carry 1080P signals.
