There are available today quite a bewildering variety of connection types utilized 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 1st audio and video connections and move up to Cayin A88t Mk2 and leads. It can give the pros and cons of those all and hopefully by the end you will end up a little more informed regarding how to get the best quality images out of your setup.
Initially – Initially things where simpler because there was only a good way to receive TV signals, through an aerial. This connection strategy is called Coax and is still used today to connect Freeview Receivers as much as the aerial on the 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 is made up of an excellent inner wire (core) with a wire mesh or foil surrounding it.
As each of the Video and Audio Details are carried down the same cable Coax is bottom of the pile when it comes to quality. Coax cannot be used to possess a high-definition signal
Composite Video – Composite video is really a boost from Coax in that the photo and Audio information is sent separately. It genuinely 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 classified as Phono (RCA) connectors and should be immediately familiar to anyone that owns a Hifi Separates System.
Component video is still used today 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 to be able to easily connect equipment towards the TV. The photo quality achieved by a composite connection is superior to with Coax yet still not great and thus is not actually ideal for HiFi XLR cable. Composite cannot be employed to have 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 the video data being sent down 2 bits of wire the picture is divided right into a signal that contains colour data (Chroma) and a signal which contains brightness data (Luma). This gives a better picture than Composite. Comparable to Composite Video, separate connections are essential for Audio and use the identical Phono (RCA) connectors as shown above.
S-Video connections can also quite often found on the front of contemporary TV and will used to quickly connect equipment like Camcorders to some 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 in order 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. But they are being phased out and should not be found on High-definition video sources including Bluray players.
Scart is actually a multicored cable that carries a variety of video connections like Composite and S-Video along with Left and Right Audio Data all conveniently located in a single socket. Generally when using a Scart Connection this is the only connection needed to connect a source to your display.
Scart cables also introduced a whole new video standard referred to as RGB where 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 become the Component Video standard which is 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 utilizes higher quality cable and connectors so you can use it to carry hi-def video signals (720P, 1080i however, not 1080P). Component Video connectors are Phono (RCA) connectors as mentioned above for Composite Video but be aware that the cable is different.
Component video connections are the most useful quality Analogue (i.e. none digital) connections available. Component Video connections are available on all Hi-def equipment i.e. HD TV’s, Bluray Players etc. Component Video Cables can be used for Line Magnetic 518ia but please remember that they cannot be used to carry 1080P signals.
