There are 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 will start with the very first audio and video connections and move up to Cayin A100t and leads. It can give the pros and cons of them all and hopefully at the end you may be a little more informed regarding how for the greatest quality images from your setup.
Initially – In the beginning things where simpler because there was just a good way to receive TV signals, through an aerial. This connection strategy is called Coax and is also still used today for connecting Freeview Receivers as much as the aerial on the roof (the freeview receiver can either be considered a separate box or built into your TV). Coax cable is what is known screened cable and consists of a solid inner wire (core) having a wire mesh or foil surrounding it.
As all of the Video and Audio Data is carried along the same cable Coax is bottom in the pile when it comes to quality. Coax cannot be utilized to possess a high definition signal
Composite Video – Composite video is a step-up from Coax because the Picture and Audio details are sent separately. It actually requires 3 separate connections (Video, Audio Left and Audio Right) to be made to be able to show a graphic with sound. The connectors used are classified as Phono (RCA) connectors and really should be immediately familiar to anyone that owns a Hifi Separates System.
Component video is still 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 to the TV. The image quality achieved by way of a composite connection is superior to with Coax but still not great and so is not actually suitable for Audiophile Cables. Composite cannot be utilized to carry a high-definition signal.
S-Video – S-Video or S-VHS is an evolution of the original composite video standard because instead of all of the video data being sent down 2 pieces of wire the picture is split up right into a signal which has colour data (Chroma) as well as a signal which has brightness data (Luma). This provides an improved picture than Composite. Much like Composite Video, separate connections are needed for Audio and use the same Phono (RCA) connectors as shown above.
S-Video connections could 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 used 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 found on High-definition video sources such as Bluray players.
Scart is actually a multicored cable that carries a variety 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 utilizing a Scart Connection this is the only connection necessary 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 which is discussed below. Scart cables cannot be used to carry high-definition video signals.
Component Video (Y, PB, PR) – Component video is an evolution of RGB mentioned above which uses high 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 mentioned above for Composite Video but be aware that the cable is unique.
Component video connections are the most useful 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 for Line Magnetic 508ia but please remember that they cannot be employed to carry 1080P signals.
