You will find available today quite a bewildering variety of connection types used for Audio and Video. To further complicate things a number of the same connectors and leads can be used for multiple connection types.
The following information begins with the very first audio and video connections and move up to Cayin Audio and leads. It can give the advantages and disadvantages of those all and hopefully by the end you will end up a little more informed about how for the best quality images from the setup.
In The Beginning – Initially things where simpler as there was just one method to receive TV signals, via an aerial. This connection technique is called Coax and is also still used today for connecting Freeview Receivers as much as the aerial on your roof (the freeview receiver may either be a separate box or that are part of your TV). Coax cable is what is known screened cable and consists of an excellent inner wire (core) having a wire mesh or foil surrounding it.
As all of the Video and Audio Information is carried on the same cable Coax is bottom in the pile in terms of quality. Coax cannot be used to have 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 genuinely requires 3 separate connections (Video, Audio Left and Audio Right) to become made in order to show a picture with sound. The connectors used are known as Phono (RCA) connectors and really should be immediately familiar to anyone who owns a Hifi Separates System.
Component video remains used 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 in order to easily connect equipment for the TV. The photo quality achieved by a composite connection is preferable to with Coax yet still not great therefore is not really 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 because instead of all the video data being sent down 2 pieces of wire the photo is broken down in to a signal which has colour data (Chroma) along with a signal that contains brightness data (Luma). This gives a much better picture than Composite. Much like Composite Video, separate connections are required for Audio and make use of exactly the same Phono (RCA) connectors as shown above.
S-Video connections could also frequently found on the front of recent TV and may used to quickly connect equipment such as Camcorders to a TV in order to show home video footage. S-Video cannot be employed to carry high-definition signals.
Scart Connections – Scart Connectors where introduced to be able 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 phased out and can not be available on High-definition video sources including Bluray players.
Scart is actually a multicored cable that carries many different video connections including Composite and S-Video in addition to Left and Right Audio Data all conveniently located in a single socket. Generally when you use a Scart Connection this is actually the only connection necessary to connect a source to some display.
Scart cables also introduced a whole 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 become 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 surely an evolution of RGB mentioned above which utilizes high quality cable and connectors so you can use it to hold high definition video signals (720P, 1080i although 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 best quality Analogue (i.e. none digital) connections available. Component Video connections can be found on all Hi-def equipment i.e. HD TV’s, Bluray Players etc. Component Video Cables can be used Line Magnetic but please be aware that they cannot be utilized to carry 1080P signals.
