You will find 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 guide will begin with the very first audio and video connections and progress to Cayin Tube Amp and leads. It will give the advantages and disadvantages of them 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.
Initially – In the beginning things where simpler as there was only one way to receive TV signals, with an aerial. This connection technique is called Coax and is still used today for connecting Freeview Receivers up to the aerial on your own roof (the freeview receiver either can be considered a separate box or that are part of your TV). Coax cable is what is known as screened cable and consists of an excellent inner wire (core) using a wire mesh or foil surrounding it.
As each 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 used to possess a high definition signal
Composite Video – Composite video is a step up from Coax because the Picture and Audio data is sent separately. It actually requires 3 separate connections (Video, Audio Left and Audio Right) to become made to be able to show a picture with sound. The connectors used are referred to as Phono (RCA) connectors and really should be immediately familiar to anyone that owns a Hifi Separates System.
Component video continues to be used right now to connect such things as Video cameras and Nintendo Wii’s to TV’s. Most TV’s will have a socket on the front or side to be able to easily connect equipment for the TV. The image quality achieved by way of a composite connection is preferable to with Coax yet still not great therefore is not actually suitable for Audiophile Cables. Composite cannot be employed to carry a high definition signal.
S-Video – S-Video or S-VHS is surely an evolution in the original composite video standard in this instead of all the video data being sent down 2 bits of wire the image is split up right into a signal that contains colour data (Chroma) as well as a signal which has brightness data (Luma). This provides a better picture than Composite. Similar to Composite Video, separate connections are needed for Audio and utilize the identical Phono (RCA) connectors as shown above.
S-Video connections may also quite often found on the front of modern TV and can utilized to quickly connect equipment including Camcorders to your TV in order to show home video footage. S-Video cannot be employed to carry high-definition signals.
Scart Connections – Scart Connectors where introduced in order to 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 now being phased out and should not be available on High-definition video sources like Bluray players.
Scart is a multicored cable that carries many different video connections including Composite and S-Video as well as Right and left Audio Data all conveniently located in a single socket. Generally when you use a Scart Connection here is the only connection necessary to connect a source to a display.
Scart cables also introduced a 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 can be discussed below. Scart cables cannot be utilized to carry high-definition video signals.
Component Video (Y, PB, PR) – Component video is surely an evolution of RGB mentioned previously which utilizes better quality cable and connectors so you can use it to carry high definition video signals (720P, 1080i but 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 found on all High Definition equipment i.e. HD TV’s, Bluray Players etc. Component Video Cables can be used as Line Magnetic 219ia but please be aware that they cannot be used to carry 1080P signals.
