    I’m not a professional, but have plenty of experience with this, so I’ll do my best to explain in laymen’s terms.

    In the case of Apple's AV cables to be used with your iPod or iPhone, it's the difference in how you connect your video feed.

    Component AV consists of 3 RCA-type plugs to carry the video feed to your TV/Monitor. With this connection you are able to send the lowest form of an HD video signal (720i and maybe 720p, but I’m not positive about the ‘p’). So with this product you’ll see 5 RCA-type plugs; 3 for the video and 2 for the audio.

    Composite AV consists of a single RCA-type plug to carry the video feed to your TV/Monitor. This is the simplest form of video feed and will have 3 RCA-type plugs; 1 for the video and 2 for the audio.

    Newer TV's and Monitors often have both options available or only component, whereas the older TV's and Monitors only have the composite option available. Be sure you check out what connections are available on your specific TV.

  • Component AV is a higher quality and has the Red, Green and Blue inputs as well as the Right and Left channel audio. Composite AV is a standard RCA with the yellow for video and red and white for audio left and right.

  • Component offers the red green blue input and this can be scaled upto full 1080p (source allowing) this is still regarded as a superior connection to HDMI.

    Composite is your general all round video input which can be put into most tvs games consoles video cameras and some dvd players come with this, if your tv doesnt have this input you can simply get a adapter which plugs into a scart plug on the back of your telly.

  • Component produces a clearer picture and has 5 plugs (Red, Green, and Blue: video, Red and White: sound). Composite is less clear but far more common and has 3 plugs (yellow: video, Red and White: sound)

    HOW IT WORKS: Your TV picture is made up of 3 colours (Red, Green, Blue). These colours combined, and at the right brightness will make up the colours we see. all 3 lit-up you get white. Red and Blue and you get violet, etc.........

    when using composite out, these tree colours are sent down 1 cable. Then are split in to there separate signals (colours) at the other end (your TV). Due to the re-separating of these colour some don't go where they are suppose to, eg: some red in the green. (not really that simple, but you get the point. lol)

    EG (composite, SD): cars, trucks and buses are going down a highway in 3 separate lanes then they come to a single lane tunnel (the cable) at witch they all merge together. At the other end they separate back in to there separate lanes, BUT, some buses are stuck in the cars lane for a few Km's until they can merge back into there lanes. ie: slowing down the traffic and mixing vehicles.(the data) not as clear as when it was sent.

    EG: (component, HD): The same theory as above applies but when you get to the tunnel (the cable) there are three lanes (Red, Green, Blue) . There for - there is no merging or slowing of the traffic (data) no need to mix the lanes. and so, a smooth clears delivery. This is the reason that this type of cabling can produce HD (720i and 720P). But don't be fooled HD and FULL HD are 2 different grades. HD has a max signal output of 720 i or p. FULL HD can produce up 1080i and 1080p. (component can support this but at a reduced quality)

    THE Difference: Component is clearer but not as common as composite.

  • the difference between those two are that the composite cables are for 480i (standard definition) TVs and the component cables are for 480p, 720p, 1080i and 1080p (enchanted and high definition) TVs

  • I also wanted to add that the P in 480p or 720p or 1080p stands for Progressive Scan which pretty much means more color changes per second resulting in a better picture or 480i 720i 1080i which means interlaced and has less color changes in a second.

  • The difference between component video and composite video is picture quality. Component video is capable of video resolutions of 1080i (HD video) where as composite video is only 240i...

    Composite video has been around for many years (25 years of my life time!) and was at the time better that your average cable TV signals. But now that we have entered the HD world, composite video is considered "old" where as component is still with the times, even though a resolution of 1080i may be considered "old" also with today's HDMI resolutions of 1080p... But component video is still around and still good enough for many HD video sources...

    If your TV has component video inputs (red, blue, green indications), then the component video cable adapter will work... However, if you still have an older TV set or even plan to connect the iPod unit to some basic video screens (especially those available for vehicle's like I plan too!), the composite video adapter will be enough...

    Hope this info helps out!

    Take care...
