You will find available today quite a bewildering variety 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 informative guide begins with the very first audio and video connections and progress to Cayin Audio and leads. It can give the advantages and disadvantages of those all and hopefully at the end you will end up a little more informed regarding how to get the best quality images out of your setup.
In The Beginning – Initially things where simpler as there was only one method to receive TV signals, via an aerial. This connection technique is called Coax and it is still used today for connecting Freeview Receivers up to the aerial on the roof (the freeview receiver can either become a separate box or built into your TV). Coax cable is what is known screened cable and is made up of an excellent inner wire (core) with a wire mesh or foil surrounding it.
As all of the Video and Audio Details are carried along the same cable Coax is bottom of the pile in terms of quality. Coax cannot be employed to possess a high-definition signal
Composite Video – Composite video is really a step-up from Coax in that the photo and Audio information is sent separately. It really requires 3 separate connections (Video, Audio Left and Audio Right) to be made to be able to show a picture with sound. The connectors used are classified as Phono (RCA) connectors and must be immediately familiar to anyone who owns a Hifi Separates System.
Component video remains used today 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 for the TV. The image quality achieved by a composite connection is better than with Coax yet still not great and so is not actually ideal for Hi-Fi Speaker Cable. Composite cannot be employed to possess a high-definition signal.
S-Video – S-Video or S-VHS is surely an evolution from the original composite video standard in that instead of all the video data being sent down 2 bits of wire the picture is divided in to a signal which has colour data (Chroma) as well as a signal that contains brightness data (Luma). This provides an improved picture than Composite. Similar to Composite Video, separate connections are essential for Audio and make use of exactly the same Phono (RCA) connectors as shown above.
S-Video connections can also frequently found on the front of recent TV and can utilized to quickly connect equipment including Camcorders to a TV to be able to show home video footage. S-Video cannot be used to carry high definition signals.
Scart Connections – Scart Connectors where introduced in order 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 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 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 here is the only connection needed to connect a source to some display.
Scart cables also introduced a brand new video standard known 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 evolved into the Component Video standard which can be 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 mentioned previously which uses high quality cable and connectors so it can be used to carry high-definition 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 unique.
Component video connections are the most effective quality Analogue (i.e. none digital) connections available. Component Video connections can be obtained on all High-definition equipment i.e. HD TV’s, Bluray Players etc. Component Video Cables can be used as Line Magnetic 508ia but please remember that they cannot be employed to carry 1080P signals.
