You can find available today quite a bewildering variety 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.
This guide begins with the 1st audio and video connections and move up to Cayin 300B and leads. It is going to give the advantages and disadvantages of these all and hopefully at the end you will be a bit more informed about how for the best quality images from your setup.
At First – At first things where simpler since there was just one method to receive TV signals, through an aerial. This connection method is called Coax and is also still used today to connect Freeview Receivers as much as the aerial on your roof (the freeview receiver may either be considered a separate box or that are part of your TV). Coax cable is what is known as screened cable and is comprised of an excellent inner wire (core) with a wire mesh or foil surrounding it.
As all of the Video and Audio Details are carried down the same cable Coax is bottom in the pile with regards to quality. Coax cannot be utilized to carry a high definition signal
Composite Video – Composite video is really a boost from Coax in this the Picture and Audio details are sent separately. It actually requires 3 separate connections (Video, Audio Left and Audio Right) to be made so that you can show a graphic with sound. The connectors used are known as Phono (RCA) connectors and should 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 to be able to easily connect equipment to the TV. The picture quality achieved with a composite connection is superior to with Coax but still not great therefore is not really appropriate for Hifi RCA Cable. Composite cannot be used to carry a high-definition signal.
S-Video – S-Video or S-VHS is definitely 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 split up into a signal which contains colour data (Chroma) as well as a signal which has brightness data (Luma). This gives an improved picture than Composite. Similar to Composite Video, separate connections are required for Audio and make use of the same Phono (RCA) connectors as shown above.
S-Video connections could also quite often found on the front of contemporary TV and can employed to quickly connect equipment including Camcorders to your 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 may still be found today on DVD players, Sky boxes and modern TV’s. Nonetheless they are now being eliminated and should not be seen 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 as well as Left and Right Audio Data all conveniently located in a single socket. Generally when you use a Scart Connection this is the only connection required to connect a source to your display.
Scart cables also introduced a brand new video standard called 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 that is discussed below. Scart cables cannot be utilized to carry hi-def video signals.
Component Video (Y, PB, PR) – Component video is definitely an evolution of RGB mentioned previously which utilizes higher quality cable and connectors so you can use it to transport 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 is unique.
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 as Line Magnetic 219ia but please bear in mind that they cannot be utilized to carry 1080P signals.
