There are available today quite a bewildering array 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.
This guide begins with the 1st audio and video connections and progress up to Cayin A88t Mk2 and leads. It will give the advantages and disadvantages of them all and hopefully at the end you will end up a little bit more informed regarding how for the best quality images from your setup.
Initially – In the beginning things where simpler since there was only one method to receive TV signals, via an aerial. This connection method is called Coax and is also still used today to connect Freeview Receivers up to the aerial on your roof (the freeview receiver can either become a separate box or that are part of your TV). Coax cable is what is known as screened cable and consists 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 have a high-definition signal
Composite Video – Composite video is actually a step-up from Coax in that the Picture and Audio details are sent separately. It genuinely requires 3 separate connections (Video, Audio Left and Audio Right) to become made to be able to show a graphic with sound. The connectors used are known as Phono (RCA) connectors and should be immediately familiar to anyone who owns a Hifi Separates System.
Component video remains used now to connect things like Video cameras and Nintendo Wii’s to TV’s. Most TV’s could have a socket on the front or side in order to easily connect equipment for the TV. The photo quality achieved with a composite connection is preferable to with Coax yet still not great and thus is not actually appropriate for HiFi XLR cable. Composite cannot be utilized to possess a hi-def signal.
S-Video – S-Video or S-VHS is surely an evolution from the original composite video standard in that instead of all of the video data being sent down 2 pieces of wire the picture is divided right into a signal which contains colour data (Chroma) and a signal that contains brightness data (Luma). This gives a better picture than Composite. Similar to Composite Video, separate connections are needed for Audio and use the identical Phono (RCA) connectors as shown above.
S-Video connections may also quite often found on the front of recent TV and can employed to quickly connect equipment like Camcorders to your TV so that you can show home video footage. S-Video cannot be employed 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 can still be found today on DVD players, Sky boxes and modern TV’s. But they are now being phased out and cannot be seen on Hi-def video sources such as Bluray players.
Scart is a multicored cable that carries a number of video connections including Composite and S-Video in addition to Right and left Audio Data all conveniently located in a single socket. Generally when you use a Scart Connection here is the only connection required to connect a source to your display.
Scart cables also introduced a new video standard known as RGB where 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 that is discussed below. Scart cables cannot be employed to carry hi-def video signals.
Component Video (Y, PB, PR) – Component video is surely an evolution of RGB stated earlier 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 pointed out above for Composite Video but be aware that the cable differs.
Component video connections are the best 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 for Line Magnetic 219ia but please be aware that they cannot be used to carry 1080P signals.
