You can find available today quite a bewildering array 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.
The following information begins with the 1st audio and video connections and move up to Cayin 300B and leads. It is going to give the pros and cons of those all and hopefully by the end you will be a little more informed about how for the greatest quality images out of your setup.
In The Beginning – In the beginning things where simpler since there was just a good way to receive TV signals, via an aerial. This connection method 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 a separate box or that are part of your TV). Coax cable is what is known screened cable and is made up of a good inner wire (core) having a wire mesh or foil surrounding it.
As all the Video and Audio Data is carried down the same cable Coax is bottom from the pile with regards to quality. Coax cannot be employed to carry a high definition signal
Composite Video – Composite video is actually a step up from Coax in that the photo and Audio data is sent separately. It really requires 3 separate connections (Video, Audio Left and Audio Right) to get made so that you can show a picture with sound. The connectors used are referred to as Phono (RCA) connectors and really should be immediately familiar to anybody 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 may have a socket on the front or side so that you can easily connect equipment to the TV. The picture quality achieved by way of a composite connection is preferable to with Coax yet still not great and so is not actually appropriate for Hifi RCA Cable. Composite cannot be utilized to carry a hi-def signal.
S-Video – S-Video or S-VHS is an evolution from the original composite video standard because instead of all the video data being sent down 2 pieces of wire the image is divided in to a signal which has colour data (Chroma) as well as a signal which has brightness data (Luma). This gives a better picture than Composite. Much like Composite Video, separate connections are essential for Audio and use the same Phono (RCA) connectors as shown above.
S-Video connections could also very often found on the front of recent TV and can used to quickly connect equipment like Camcorders to your TV in order to show home video footage. S-Video cannot be employed 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 can still be found today on DVD players, Sky boxes and modern TV’s. Nonetheless they are now being phased out and cannot be seen on High-definition video sources including Bluray players.
Scart is actually a multicored cable that carries a number of 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 needed to connect a source to a display.
Scart cables also introduced a new video standard called RGB in which 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 utilized 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 transport hi-def video signals (720P, 1080i but not 1080P). Component Video connectors are Phono (RCA) connectors as stated before 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 Line Magnetic 518ia but please be aware that they cannot be employed to carry 1080P signals.
