You can 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.
The following information will begin with the 1st audio and video connections and move up to Cayin Tube Amp and leads. It is going to give the pros and cons of them all and hopefully at the end you will end up a little more informed about how to get the best quality images from your setup.
At First – In the beginning things where simpler as there was only one way to receive TV signals, via an aerial. This connection technique is called Coax and is also still used today for connecting Freeview Receivers approximately the aerial on your roof (the freeview receiver either can be a separate box or that are part of your TV). Coax cable is what is known screened cable and is comprised of a solid inner wire (core) with a wire mesh or foil surrounding it.
As all the Video and Audio Details are carried on the same cable Coax is bottom of the pile with regards to quality. Coax cannot be utilized to carry a high definition signal
Composite Video – Composite video is actually a step up from Coax in that the Picture and Audio information is sent separately. It genuinely requires 3 separate connections (Video, Audio Left and Audio Right) to become made to be able to show an image with sound. The connectors used are referred to as Phono (RCA) connectors and should be immediately familiar to anyone that owns a Hifi Separates System.
Component video remains used right now to connect things such 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 towards the TV. The image quality achieved by a composite connection is superior to with Coax but still not great and so is not really appropriate for Audiophile Cables. Composite cannot be used to have a high-definition signal.
S-Video – S-Video or S-VHS is surely an evolution in the original composite video standard because instead of all video data being sent down 2 pieces of wire the photo is broken down right into a signal which has colour data (Chroma) along with a signal that contains brightness data (Luma). This offers a better picture than Composite. Much like Composite Video, separate connections are essential for Audio and use the identical Phono (RCA) connectors as shown above.
S-Video connections can also quite often found on the front of modern TV and will utilized to quickly connect equipment such as Camcorders to your TV to be able to show home video footage. S-Video cannot be utilized to carry hi-def 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. However they are being eliminated and can not be available on High Definition video sources including Bluray players.
Scart is actually a multicored cable that carries a variety of video connections like Composite and S-Video in addition to Right and left Audio Data all conveniently located in a single socket. Generally when utilizing a Scart Connection this is actually the only connection necessary to connect a source to a display.
Scart cables also introduced a new video standard known as RGB wherein 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 is discussed below. Scart cables cannot be used to carry hi-def 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 you can use it to transport hi-def video signals (720P, 1080i but not 1080P). Component Video connectors are Phono (RCA) connectors as mentioned above 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 518ia but please bear in mind that they cannot be utilized to carry 1080P signals.
