I have just quoted what he commented on the original article about the video cable wiring. Chances that you'll get hold of him over there is better: http://www.oreillynet.com/cs/user/view/cs_msg/76989 His nick is <em>iPod_Brett</em> Hector, I doubt you’ll get in contact with Brett through this web page.

I know nothing, but I like to know if you can tell me how to re-connect my Monster cable to my (i.EEE 1394) digital interface. Or may be make a connection to a USB cable end. ??? Do you understand me? I am not too good at this but I am very persistant at trying to figure things up.! I have a Sony camcorder with an av mini rc jack output, and I'd like to connect it to my Sony Laptop that has the firewire connection. Can you show me how to do it? I guess it's a matter of knowing what wire goes where? Please help, or if you have any comments please do so. Yours Truly: Hector Hey Brett, it sounds like you know plenty in wiring!!!

As an engineer of portable devices, I can honestly say I probably would have done the same thing as Apple.

Here’s why:

If you look first at the IPOD AUDIO vs STANDARD AUDIO, you’ll notice the LEFT and RIGHT channels are reversed. I’m not sure why they did that but it’s bunk. Something to keep in mind when using any standard audio cable as well.

A typical video camera will <em>not</em> work with headphones plugged into the 3,5 mm minijack. Apple has decided to use the same port for headphones and line out (which is a good decision for a small device), and this faces them with two alternatives: 1. Use standard headphones and non-standard(*) A/V cable 2. Use a standard(*) A/V cable and non-standard headphones. I guess we all are glad that they did not choose the second alternative. Being limited to only use Apple headphones (or carrying an adapter) would not be acceptable. So Erik, you have a wonderful blog but on this post I have to disagree. PS. I bougt the Apple A/V cable with my iPod 5G as well. Expensive, allright, but it deffinately oozes with quality. (*) What I (and Erik) refer to as standard is actually not a standard. According to what I've read on the net, different brands of videocameras use different cables from 3.5 mm jack to RCA. Tor Erik is right.

Are you sure this isn’t because the connections on the mini jack has to be different on the iPod (compared to video cameras). Simply because the iPod jack also has to fit regular stereo headphones?

Would you get correct stereo sound if you plug your headphones into the AV connection on a video camera?
