You will find available today quite a bewildering array 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.
This guide begins with the first audio and video connections and move up to Cayin A100t and leads. It is going to give the pros and cons of them all and hopefully at the end you will be a little more informed about how exactly to get the best quality images from your setup.
Initially – At first things where simpler because there was just one way to receive TV signals, with an aerial. This connection strategy is called Coax and it is still used today to connect Freeview Receivers as much as the aerial on the roof (the freeview receiver can either be considered a separate box or built into your TV). Coax cable is what is known screened cable and is made up of a good inner wire (core) having a wire mesh or foil surrounding it.
As all of the Video and Audio Data is carried on the same cable Coax is bottom from the pile in terms of quality. Coax cannot be utilized to possess a high-definition signal
Composite Video – Composite video is really a step-up from Coax because the photo and Audio details are sent separately. It really requires 3 separate connections (Video, Audio Left and Audio Right) to become made in order to show an image 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 right now to connect things like Video cameras and Nintendo Wii’s to TV’s. Most TV’s will have a socket on the front or side so that you can easily connect equipment for the TV. The picture quality achieved with a composite connection is better than with Coax yet still not great therefore is not really suitable for Hifi RCA Cable. Composite cannot be employed to carry a high definition signal.
S-Video – S-Video or S-VHS is an evolution in the original composite video standard because instead of all video data being sent down 2 bits of wire the photo is split up into a signal that contains colour data (Chroma) and a signal that contains brightness data (Luma). This gives an improved picture than Composite. Similar to Composite Video, separate connections are essential for Audio and use the identical Phono (RCA) connectors as shown above.
S-Video connections can also frequently found on the front of contemporary TV and can employed to quickly connect equipment including Camcorders to a 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 so that you can allow simple single cable connections between video equipment. Scart connections can nonetheless be found today on DVD players, Sky boxes and modern TV’s. Nonetheless they are being eliminated and should not be available on Hi-def video sources including Bluray players.
Scart is really a multicored cable that carries a number of video connections including Composite and S-Video in addition to Right and left Audio Data all conveniently located in a single socket. Generally when you use a Scart Connection this is actually the only connection required to connect a source to a display.
Scart cables also introduced a brand new video standard referred to as 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 become the Component Video standard which is discussed below. Scart cables cannot be employed to carry hi-def 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 high-definition video signals (720P, 1080i but 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 Line Magnetic 518ia but please bear in mind that they cannot be employed to carry 1080P signals.
